Commitments and Contingencies	Sep. 30, 2025
Other Provisions, Contingent Liabilities, and Contingent Assets [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments – The Company enters into several purchase agreements and supplementary agreements with its third-party manufacturers and suppliers for future deliveries of equipment and components. In addition, the Company enters into intellectual property and licensing agreements with third parties. The total future payments under these agreements amounted to $808 million as of September 30, 2025. Purchase commitments of $610 million are due within the next 12 months. Additionally, the Company obtained letters of credit and bank guarantees to guarantee payments for utility suppliers, foreign statutory payroll related charges, and other purposes. The Company has obtained total facilities of $132 million and $129 million as of September 30, 2025 and December 31, 2024, respectively. Contingencies – From time to time, the Company is a party to claims that arise in the normal course of business. These claims include allegations of infringement of intellectual property rights of others as well as other claims of liability. In addition, the Company, on a case by case basis, includes intellectual property indemnification provisions in the terms of sale and technology licenses with third parties. The Company is also subject to various taxes in the different jurisdictions in which it operates. These include property, goods and services, and other non-income taxes. The Company accrues costs associated with these matters when they become probable and reasonably estimable. The Company does not believe it is probable that losses associated with these matters beyond those already recognized will be incurred in amounts that would be material to the interim financial statements. The Company has determined that due to the complexity of calculation of the Advanced Manufacturing Investment Tax Credit ("AMITC") under the Internal Revenue Code Section 48D, and uncertainties regarding compliance with program conditions, it is probable that a portion of AMITC computed and claimed in the United States may be repayable. Management recorded its best estimate of the amount of the AMITC that may be repayable totaling $44 million as of September 30, 2025. The amount of the reserve may change depending on future assessments by tax authorities.

Accounting Policies, Changes In Accounting Estimates And Errors [Abstract]
Statement of Compliance	Statement of Compliance — The interim condensed consolidated financial statements ("interim financial statements") have been prepared in accordance with International Accounting Standards ("IAS") 34, Interim Financial Reporting ("IAS 34"), as issued by the International Accounting Standards Board ("IASB"). Certain information and footnote disclosures normally included in the annual audited consolidated financial statements prepared in accordance with International Financial Reporting Standards (“IFRS”) Accounting Standards, as issued by the IASB, have been omitted or condensed. These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in GlobalFoundries' Annual Report on Form 20-F for the year ended December 31, 2024. The interim financial statements have been prepared on a basis consistent with the accounting policies disclosed in the December 31, 2024 audited consolidated financial statements. The interim financial statements are unaudited and reflect adjustments (consisting of normal recurring adjustments) that are, in the opinion of management, necessary to provide a fair statement of results for the interim periods in accordance with IAS 34 as issued by the IASB. The interim financial statements were authorized by the Audit, Risk and Compliance Committee of GlobalFoundries’ Board of Directors on November 12, 2025, to be issued and subsequent events have been evaluated for their potential effect on the interim financial statements through November 12, 2025.
Summary of Material Accounting Policies and Critical Judgments, Estimates and Assumptions	Summary of Material Accounting Policies and Critical Judgments, Estimates and Assumptions — The summary of material accounting policies and critical judgments, estimates and assumptions adopted in the preparation of the interim financial statements are consistent with those followed in the preparation of the Company's annual audited consolidated financial statements contained in our Annual Report on Form 20-F for the year ended December 31, 2024 except for the additions to the Business Combination accounting policy as described below. Business Combinations — The Company accounts for its business combinations using the acquisition method of accounting. The purchase price of acquisitions is allocated to the assets, including separately identifiable assets acquired and the liabilities assumed based on their estimated fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of identifiable assets and liabilities is recorded as goodwill. The acquired intangible assets consisting of the trademark, developed technology, in-process research and development and customer relationships are recorded at fair value at the date of acquisition, based on management’s estimates. Acquisition-related expenses are expensed as incurred.
Recent Accounting Pronouncements, Not Adopted	Recent Accounting Pronouncements, Not Adopted: The Company has not adopted the following new, revised or amended IFRS standards that have been issued by the IASB that are not yet effective: Classification and Measurement of Financial Instruments (Amendments to IFRS 9, Financial Instruments and IFRS 7, Financial Instruments: Disclosures) — The amendments clarify the requirements for the timing of recognition and derecognition of certain financial assets and liabilities, add further guidance for assessing whether a financial asset meets the solely payments of principal and interest criterion and add new disclosures for certain instruments with contractual terms that can change cash flows. The effective date for adoption of these amendments is annual periods beginning on or after January 1, 2026. The Company does not expect a material impact to the financial statements upon adoption of these amendments. Annual Improvements to IFRS Accounting Standards — Volume 11 — These narrow-scope amendments relate to clarifications, simplifications, corrections or changes to improve consistency in the following IFRSs: IFRS 7, Financial Instruments: Disclosures, IFRS 9, Financial Instruments, IFRS 10, Consolidated Financial Instruments and IAS 7, Statement of Cash Flows. The effective date for adoption of these amendments is annual periods beginning on or after January 1, 2026. The Company does not expect a material impact to the financial statements upon adoption of these amendments. Contracts Referencing Nature-dependent Electricity — Amendments to IFRS 9 and IFRS 7 — These amendments help entities better report the financial effects of nature-dependent electricity contracts, which are often structured as power purchase agreements. The amendments include clarifying the application of the own-use requirements, permitted hedge accounting if these contracts are used as hedging instruments and adding new disclosure requirements to enable investors to understand the effect of these contracts on an entity’s financial performance and cash flows. The amendments are effective for annual periods beginning on or after January 1, 2026. The Company expects these amendments may require certain additional disclosures going forward, but does not expect a material impact to the financial statements upon adoption of these amendments. IFRS 18, Presentation and Disclosure in Financial Statements ("IFRS 18") — This new standard will replace IAS 1, Presentation of Financial Statements. The key concepts in IFRS 18 relate to the structure of the statement of profit or loss, required disclosures in the financial statements for certain management-defined performance measures and enhanced principles on aggregation and disaggregation which apply to the primary financial statements and notes in general. •IFRS 18 introduces new requirements for presentation within the statement of profit or loss, including specified totals and subtotals. Entities are required to classify all income and expenses within the statement of profit or loss into one of five categories: operating, investing, financing, income taxes and discontinued operations, whereof the first three are new. •IFRS 18 also requires disclosure of newly defined management-defined performance measures, subtotals of income and expenses, and includes new requirements for aggregation and disaggregation of financial information based on the identified ‘roles’ of the primary financial statements and the notes to the financial statements. •In addition, narrow-scope amendments have been made to IAS 7, Statement of Cash Flows, which include changing the starting point for determining cash flows from operations under the indirect method, from ‘profit or loss’ to ‘operating profit or loss’ and removing the optionality around classification of cash flows from dividends and interest. In addition, there are consequential amendments to several other standards. The effective date for adoption of this standard is annual periods beginning on or after January 1, 2027, and earlier adoption is permitted. Retrospective application is required. The financial impact is not yet known or reasonably estimable as of the date the accompanying financial statements were authorized for issue. The Company continues to evaluate the impact of the aforementioned standard on its financial position and performance and related applicable periods. New Legislation — On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law in the United States, which contained significant tax legislation that is expected to impact the Company. We expect to see a positive impact as a result of an increase to the Advanced Manufacturing Investment Tax Credit ("AMITC") under the CHIPS Act from 25% to 35% beginning in tax year 2026. The OBBBA also allows for immediate deduction of certain research and development costs rather than capitalization and amortization, expands accelerated tax depreciation, and contains various international tax law changes. Due to the non-recognition of net deferred tax assets in the U.S. under IAS 12 and because the Company is subject to CAMT, there is no material financial statement impact in the current period related to the Internal Revenue Code ("IRC") 174 or bonus depreciation changes. The Company anticipates a material change to its income tax disclosures for unrecognized deferred tax assets for the year ending December 31, 2025.
Earnings Per Share	Basic earnings per share ("EPS") is based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share is based upon the weighted average number of common shares outstanding during the period, assuming the issuance of common shares for all potentially dilutive common shares outstanding.

Fair value measurements of assets and liabilities [Abstract]

Fair Value Measurements

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:

•Level 1: Observable inputs such as quoted prices in active markets for identical assets or liabilities.

•Level 2: Inputs other than quoted prices in active markets in Level 1, such as quoted prices for similar assets or liabilities in active markets, quoted prices for similar assets or liabilities that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

•Level 3: Unobservable inputs for which little or no market data exists, therefore requiring management judgment to develop the Company’s own models with estimates and assumptions.

Cash Equivalents – Cash equivalents include investments in government obligation-based money market funds, other money market instruments and interest-bearing deposits with initial or remaining terms of three months or less. The fair value of cash equivalents approximates its carrying value due to the short-term nature of these instruments.

Marketable Securities – Marketable securities utilizing Level 1 and Level 2 inputs include U.S. Treasury Securities, U.S. Government Sponsored Enterprises, floating rate securities, money market mutual funds, corporate debt instruments and other notes, bonds or debt securities issued by non-U.S. sovereign or multilateral entities, as these securities all have quoted prices in active markets.

The following table presents the Company’s assets and liabilities measured at fair value on a recurring basis:


			Quoted Prices Identical Assets / Liabilities		Significant Other Inputs		Significant Unobservable Inputs

(2) Included in current and non-current receivables, prepayments and other assets on the Company’s interim condensed consolidated statements of financial position.

During the nine months ended September 30, 2025, there were no transfers between Level 1, Level 2 or Level 3 fair value measurements. During the nine months ended September 30, 2024, marketable securities with carrying amounts of $646 million, were transferred from Level 1 to Level 2. These transfers occurred as the Company reassessed the market activity of these securities.

Assets Measured and Recorded at Fair Value on a Non-Recurring Basis

Certain assets such as equity method investments, intangible assets and property, plant and equipment, and other non-financial assets, are recorded at fair value only if an impairment or observable price adjustment is recognized in the current period.

Financial Instruments Not Recorded at Fair Value on a Recurring Basis

Financial instruments not recorded at fair value on a recurring basis include grants receivable, loans receivable, lease obligations and the current and non-current portions of the Company’s long-term debt which are measured at amortized cost.

Estimated fair values of long-term debt are based on quoted prices for similar liabilities for which significant inputs are observable and represent a Level 2 valuation. The fair values are estimated based on the type of loan and maturity. The Company estimates the fair value using market interest rates for debts with similar maturities.

Related Party Disclosures

The total amounts of $0 and $9 million due from related parties as of September 30, 2025 and December 31, 2024, respectively, have been included in receivables, prepayments and other assets. The $4 million and $20 million due to related parties as of September 30, 2025 and December 31, 2024, respectively, have been included in trade and other payables.

Related party balances disclosed in the interim financial statements relate to MDC General Services Holding Company LLC, Mamoura Holdings (US) LLC, and Silicon Manufacturing Partners Pte Ltd. ("SMP"). As of December 31, 2024, we held a 49% interest in SMP, a joint venture with Avago Technologies International Sales Pte. Limited ("Avago Singapore"), and managed all aspects of its manufacturing operations. In the first quarter of 2025, we acquired the remaining 51% of the shares in the share capital of SMP from Avago Singapore, thereby making SMP a wholly-owned subsidiary of GlobalFoundries. Consequently, SMP no longer qualifies as a related party due to this change in ownership structure.

The following table presents the related party transactions included in the interim condensed consolidated statements of operations:

The interim financial statements were authorized by the Audit, Risk and Compliance Committee of GlobalFoundries’ Board of Directors on November 12, 2025, to be issued and subsequent events have been evaluated for their potential effect on the interim financial statements through November 12, 2025. Summary of Material Accounting Policies and Critical Judgments, Estimates and Assumptions — The summary of material accounting policies and critical judgments, estimates and assumptions adopted in the preparation of the interim financial statements are consistent with those followed in the preparation of the Company's annual audited consolidated financial statements contained in our Annual Report on Form 20-F for the year ended December 31, 2024 except for the additions to the Business Combination accounting policy as described below. Business Combinations — The Company accounts for its business combinations using the acquisition method of accounting. The purchase price of acquisitions is allocated to the assets, including separately identifiable assets acquired and the liabilities assumed based on their estimated fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of identifiable assets and liabilities is recorded as goodwill. The acquired intangible assets consisting of the trademark, developed technology, in-process research and development and customer relationships are recorded at fair value at the date of acquisition, based on management’s estimates. Acquisition-related expenses are expensed as incurred. Recent Accounting Pronouncements, Not Adopted: The Company has not adopted the following new, revised or amended IFRS standards that have been issued by the IASB that are not yet effective: Classification and Measurement of Financial Instruments (Amendments to IFRS 9, Financial Instruments and IFRS 7, Financial Instruments: Disclosures) — The amendments clarify the requirements for the timing of recognition and derecognition of certain financial assets and liabilities, add further guidance for assessing whether a financial asset meets the solely payments of principal and interest criterion and add new disclosures for certain instruments with contractual terms that can change cash flows. The effective date for adoption of these amendments is annual periods beginning on or after January 1, 2026. The Company does not expect a material impact to the financial statements upon adoption of these amendments. Annual Improvements to IFRS Accounting Standards — Volume 11 — These narrow-scope amendments relate to clarifications, simplifications, corrections or changes to improve consistency in the following IFRSs: IFRS 7, Financial Instruments: Disclosures, IFRS 9, Financial Instruments, IFRS 10, Consolidated Financial Instruments and IAS 7, Statement of Cash Flows. The effective date for adoption of these amendments is annual periods beginning on or after January 1, 2026. The Company does not expect a material impact to the financial statements upon adoption of these amendments. Contracts Referencing Nature-dependent Electricity — Amendments to IFRS 9 and IFRS 7 — These amendments help entities better report the financial effects of nature-dependent electricity contracts, which are often structured as power purchase agreements. The amendments include clarifying the application of the own-use requirements, permitted hedge accounting if these contracts are used as hedging instruments and adding new disclosure requirements to enable investors to understand the effect of these contracts on an entity’s financial performance and cash flows. The amendments are effective for annual periods beginning on or after January 1, 2026. The Company expects these amendments may require certain additional disclosures going forward, but does not expect a material impact to the financial statements upon adoption of these amendments. IFRS 18, Presentation and Disclosure in Financial Statements ("IFRS 18") — This new standard will replace IAS 1, Presentation of Financial Statements. The key concepts in IFRS 18 relate to the structure of the statement of profit or loss, required disclosures in the financial statements for certain management-defined performance measures and enhanced principles on aggregation and disaggregation which apply to the primary financial statements and notes in general. •IFRS 18 introduces new requirements for presentation within the statement of profit or loss, including specified totals and subtotals. Entities are required to classify all income and expenses within the statement of profit or loss into one of five categories: operating, investing, financing, income taxes and discontinued operations, whereof the first three are new. •IFRS 18 also requires disclosure of newly defined management-defined performance measures, subtotals of income and expenses, and includes new requirements for aggregation and disaggregation of financial information based on the identified ‘roles’ of the primary financial statements and the notes to the financial statements. •In addition, narrow-scope amendments have been made to IAS 7, Statement of Cash Flows, which include changing the starting point for determining cash flows from operations under the indirect method, from ‘profit or loss’ to ‘operating profit or loss’ and removing the optionality around classification of cash flows from dividends and interest. In addition, there are consequential amendments to several other standards. The effective date for adoption of this standard is annual periods beginning on or after January 1, 2027, and earlier adoption is permitted. Retrospective application is required. The financial impact is not yet known or reasonably estimable as of the date the accompanying financial statements were authorized for issue. The Company continues to evaluate the impact of the aforementioned standard on its financial position and performance and related applicable periods. New Legislation — On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law in the United States, which contained significant tax legislation that is expected to impact the Company. We expect to see a positive impact as a result of an increase to the Advanced Manufacturing Investment Tax Credit ("AMITC") under the CHIPS Act from 25% to 35% beginning in tax year 2026. The OBBBA also allows for immediate deduction of certain research and development costs rather than capitalization and amortization, expands accelerated tax depreciation, and contains various international tax law changes. Due to the non-recognition of net deferred tax assets in the U.S. under IAS 12 and because the Company is subject to CAMT, there is no material financial statement impact in the current period related to the Internal Revenue Code ("IRC") 174 or bonus depreciation changes. The Company anticipates a material change to its income tax disclosures for unrecognized deferred tax assets for the year ending December 31, 2025.

Share-Based Compensation	9 Months Ended
Share-Based Compensation	Sep. 30, 2025
Share-based payment arrangements [Abstract]
Share-Based Compensation	Share-Based Compensation We measure and recognize compensation expense related to share-based transactions, including employee, consultant, and non-employee director share option awards, in our consolidated financial statements based on fair value. The fair value of each award is estimated on the date of grant using the Black-Scholes option pricing model for options, and the Monte Carlo simulation model for the performance share units and a share price at the grant date for the restricted share units. The Black-Scholes model and Monte Carlo model both require management to make certain assumptions of future expectations based on historical and current data. The assumptions include the expected term of the awards, expected volatility, dividend yield and risk-free interest rate. The expected term represents the amount of time that awards granted are expected to be outstanding, based on forecasted exercise behavior. The option pricing model requires the input of highly subjective assumptions, including the estimated fair value of the Company’s stock, expected term of the awards, expected volatility of the price of the Company’s shares, risk free interest rate and the expected dividend yield of ordinary shares. The assumptions used to determine the fair value of the option awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. The Company estimates the expected forfeiture for options utilizing historical data, and only recognizes expense when a defined liquidity event (change in control or IPO) is deemed probable on the number of awards that are expected to vest. After applying a forfeiture estimate during each reporting period for when they are probable of vesting, the Company recognizes expense on a graded attribution basis for each tranche of the award over the period from the grant date to the later of the one-year anniversary of estimated time following a liquidity event or the legal vesting dates. The Company offers an Employee Stock Purchase Plan which provides eligible employees with an opportunity to purchase our ordinary shares through payroll deductions of up to 10% of their eligible compensation. A participant may purchase a maximum of 2,500 ordinary shares during the purchase period. Amounts deducted and accumulated by the participant are used to purchase ordinary shares at the end of each six-month period, with the Company matching 20% of each employee's contributions on an after-tax basis.

Income taxes [Abstract]
Income taxes	Income taxes For tax reporting purposes, the Company consolidates its entities under GLOBALFOUNDRIES Inc., a Cayman Islands entity. As a Cayman Islands entity, the Company’s domestic statutory income tax rate is 0.0%. The difference between the Company’s domestic statutory income tax rate and its effective income tax rate reflected in income tax benefit or income tax expense is primarily due to the effect of tax rates and permanent differences in other jurisdictions in which the Company operates. Applicable to tax years beginning in 2025, the Company's effective tax rate is not currently materially impacted by Pillar Two minimum top-up taxes but may be in the future. There is no material financial statement impact in the current period related to the Internal Revenue Code ("IRC") 174 or bonus depreciation changes as it relates to the OBBBA. The effective tax rate was (12.7)% and 8.7% for the three months ended September 30, 2025 and 2024, respectively, and was (8.0)% and 9.7% for the nine months ended September 30, 2025 and 2024, respectively. The decrease was primarily the result of tax benefits related to exchange rate differences on the base of certain non-monetary assets in Germany and tax benefit from recognition of German deferred tax assets that are no longer contingent, offset by tax expense related primarily to true-up of Singapore incentive tax rates.
