Accounting Policies [Abstract]
Basis of Presentation	Equinix, Inc. ("Equinix," the "Company," "we," "our," or "us") was incorporated in Delaware on June 22, 1998. We have been operating as a real estate investment trust ("REIT") for U.S. federal income tax purposes since 2015. The accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to fairly state the financial position and the results of operations for the interim periods presented. Our condensed consolidated balance sheet data as of December 31, 2025 has been derived from audited consolidated financial statements as of that date. Our condensed consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission ("SEC"), but omit certain information and footnote disclosure necessary to present the statements in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP" or "GAAP"). For further information, refer to the Consolidated Financial Statements and Notes thereto included in our Form 10-K as filed with the SEC on February 11, 2026. Results for the interim periods are not necessarily indicative of results for the entire fiscal year. Certain prior period amounts have been reclassified in the condensed consolidated financial statements to conform with current year presentation.
Consolidation	Intercompany accounts and transactions have been eliminated in consolidation.
Income Taxes	Income Taxes We accrue for income taxes during interim periods based on the estimated annual effective tax rate. The effective tax rate is subject to change in the future due to various factors such as our operating performance, tax law changes and future business acquisitions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2024-03: Disaggregation of Income Statement Expenses ("DISE"). The ASU requires additional disclosure of the nature of expenses included in the income statement. The ASU is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. Early adoption is permitted. We are currently evaluating the extent of the impact of this ASU on disclosures in our condensed consolidated financial statements. In September 2025, the FASB issued ASU 2025-06: Targeted Improvements to the Accounting for Internal-Use Software. The ASU is intended to increase the operability of the recognition guidance for internal-use software considering different methods of software development. The ASU is effective for annual and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The ASU permits prospective, retrospective or modified retrospective application. We are currently evaluating the extent of the impact of this ASU on our condensed consolidated financial statements. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The ASU is intended to improve the guidance in Topic 270, Interim Reporting, by improving the navigability of the required interim disclosures and clarifying when that guidance is applicable. The ASU is effective for interim reporting periods beginning after December 15, 2027, with early adoption permitted. The ASU permits prospective or retrospective application. We are currently evaluating the extent of the impact of this ASU on disclosures in our consolidated financial statements.
Remaining Performance Obligations	Remaining Performance Obligations Approximately $14.2 billion of revenues, including deferred installation revenues, are expected to be recognized in future periods related to unsatisfied performance obligations as of March 31, 2026. Most of our revenue contracts have an initial term varying from one to five years, and thereafter automatically renew in one-year increments. Included in the remaining performance obligations are contracts that are either under the initial term or under one-year renewal periods. We expect to recognize approximately 65% of our remaining performance obligations as revenues over the next two years, with more revenues expected to be recognized in the first year due to the impact of contract renewals. The remainder of the balance is generally expected to be recognized over the next three to five years. We estimate our remaining performance obligations at a point in time. Actual amounts and timing of revenue recognition may differ from these estimates due to changes in actual deployment dates, contract modifications, scheduled price increases, renewals and/or terminations. The remaining performance obligations do not include variable consideration related to unsatisfied performance obligations such as the usage of metered power, service fees from xScale® data centers that are based on future events or actual costs incurred in the future, or any contracts that could be terminated without any significant penalties including the majority of interconnection revenues. The remaining performance obligations above include revenues to be recognized in the future related to arrangements where we are considered the lessor.
Derivatives and Other Instruments Designated as Hedging Instruments	Derivatives and Other Instruments Designated as Hedging Instruments Net Investment Hedges Foreign Currency Debt: We are exposed to the impact of foreign exchange rate fluctuations on the value of investments in our foreign subsidiaries whose functional currencies are other than the U.S. dollar. In order to mitigate the impact of foreign currency exchange rates, we have entered into various foreign currency debt obligations, which are designated as hedges against our net investments in foreign subsidiaries. As of December 31, 2025, the total principal amount of foreign currency debt obligations designated as net investment hedges was $923 million. As of March 31, 2026, no foreign currency debt obligations were designated as net investment hedges. Foreign Currency Forward Contracts: We use foreign currency forward contracts, designated as net investment hedges, to hedge against the effect of foreign exchange rate fluctuations on our net investment in our foreign subsidiaries. We use the spot method to assess hedge effectiveness and recognize fair value changes from spot rates in other comprehensive income (loss). We exclude forward points from the assessment of hedge effectiveness and amortize the initial value of the excluded component through interest expense. The difference between fair value changes from the excluded component and the amount amortized is recognized in other comprehensive income (loss). Embedded Derivatives: Certain of our customer agreements that are priced in currencies different from the functional or local currencies of the parties involved are deemed to have foreign currency forward contracts embedded in them. These embedded derivatives are separated from their host contracts and carried on our balance sheet at their fair value. The majority of these embedded derivatives arise as a result of our foreign subsidiaries pricing their customer contracts in U.S. dollars. We use some of these forward contracts embedded within our customer agreements to hedge against the effect of foreign exchange rate fluctuations on our net investment in our foreign subsidiaries. As of March 31, 2026 and December 31, 2025, the total remaining contract value of such customer agreements under this hedging program was $38 million and $230 million, respectively. Cross-currency Interest Rate Swaps: We also use cross-currency interest rate swaps, designated as net investment hedges, which effectively convert a portion of our U.S. dollar-denominated fixed-rate debt to foreign currency-denominated fixed-rate debt, to hedge the currency exposure associated with our net investment in our foreign subsidiaries. We use the spot method to assess hedge effectiveness and recognize fair value changes from spot rates in other comprehensive income (loss). Cash Flow Hedges Foreign Currency Forward Contracts: We enter into intercompany foreign currency forward contracts ("intercompany derivatives") with our wholly-owned subsidiaries in our EMEA region in order to hedge certain forecasted revenues and expenses denominated in currencies other than the U.S. dollar (primarily the British pound and the euro). Simultaneously, we enter into foreign currency forward contracts with unrelated third parties to externally hedge the net exposure created by such intercompany derivatives. We designate the intercompany derivatives as cash flow hedges. We do not exclude any components from the assessment of hedge effectiveness and the change in fair value of these derivatives is recognized in other comprehensive income (loss) until the hedged transaction occurs.
Fair Value Measurements	We perform fair value measurements in accordance with ASC 820, Fair Value Measurement, which establishes three levels of inputs that we use to measure fair value: •Level 1: quoted prices in active markets for identical assets or liabilities. •Level 2: observable inputs (e.g., spot rates and other data from third-party pricing vendors for our derivative instruments, credit rating and current prices of similar debt instruments that are publicly traded for our debt instruments) other than quoted market prices included within Level 1 that are observable, either directly or indirectly, for the assets or liabilities. •Level 3: unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities, including indicative pricing from third parties for similar instruments and asset-specific yield adjustments for elements such as credit risk.

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.
