Tether International, S.A. de C.V. has successfully completed a full independent financial statement audit by KPMG U.S. for the year ended December 31, 2025, receiving an unqualified audit opinion. This milestone marks the largest inaugural financial audit in history, verifying balance sheets, reserves exceeding liabilities by $6.814 billion, and physical gold bars.
Breaking the Attestation Barrier
For years, the digital asset ecosystem operated on quarterly reserve attestations. These reports provided time-limited snapshots of holdings rather than comprehensive financial evaluations. That structural reliance shifted on August 13, 2026, when Tether announced the completion of its full financial statement audit.
KPMG U.S. issued an unqualified audit opinion on Tether’s 2025 financial statements. In auditing terminology, an unqualified opinion represents the most positive evaluation an independent auditor can issue. It confirms that the financial statements present fairly, in all material respects, the financial position of the company in accordance with U.S. generally accepted accounting principles.
This audit went far beyond headline figures. According to Tether, the Big Four accounting firm examined transactions, systems, ownership records, valuations, counterparties, and the underlying evidence supporting the balance sheet, income statement, changes in equity, and cash flow statements.
Physical Verification of Reserve Assets
Rather than relying solely on third-party custodian reports, KPMG auditors executed direct physical verification.
As part of the substantive testing process, KPMG physically counted and inspected every individual gold bar held by Tether. Auditors verified the existence and matching identifying information of each bar on-site. This level of granular verification establishes a stark contrast with historical reporting models.
The audited financial statements for the period ending December 31, 2025, report that total reserves exceed issued token liabilities by $6.814 billion. Company executives emphasize that this financial cushion validates the quality of previous public attestation reports.
Leadership Perspective on the Audit
Tether CEO Paolo Ardoino addressed the historic scope of the project following the announcement. Ardoino noted that detractors previously claimed an audit of this scale could not be completed, pointing to the latest review as definitive proof of operational transparency under AICPA standards.
Chief Financial Officer Simon McWilliams highlighted the internal engineering required to meet Big Four standards. McWilliams described the undertaking as one of the most ambitious projects in the company’s history, noting that the finance team subjected its systems to rigorous independent evaluation to match the operational benchmarks of the world’s leading traditional enterprises.
The 30-Second Verdict

- Scope: Full financial statement audit for the year ended December 31, 2025.

By moving from periodic snapshots to a comprehensive, unqualified financial audit, Tether has set a new reporting benchmark for the broader stablecoin market. The completion of this review bridges the gap between decentralized digital assets and traditional corporate accounting standards.
