Tether Wraps Up Crypto's Biggest First-Time Financial Audit

Tether, the issuer of the USDT stablecoin, said on Aug. 13, 2026 it has completed its first full, independent financial statement audit, ending a long-running criticism that the company had never undergone a comprehensive review. The audit was conducted by KPMG U.S. and covers Tether's full 2025 financial year. KPMG delivered an unqualified opinion, the highest form of audit assurance, indicating it found no material misstatements and that the financial statements present a true and fair view of the company's position. Tether described the engagement as the largest inaugural financial audit in digital-asset history, a characterization supported by the scale of its balance sheet and operations. At the time KPMG's engagement was announced in March 2026, USDT's market capitalization exceeded $184 billion, a level comparable to the GDP of many midsized economies. Tether's reserves include about $141 billion in U.S. Treasuries, putting the company among the world's largest holders of American government debt alongside sovereign wealth funds and major central banks. Tether also reported roughly $1 billion in profit for Q1 2026, reflecting a model in which tokens are issued, backed with yield-bearing assets, and the yield is retained by the issuer. The company said it had an estimated 550 million users at the time of KPMG's engagement. KPMG was selected through a competitive process in March 2026, replacing BDO Italia, which had been providing quarterly attestation reports. Tether emphasized the distinction: attestations verify that reserves match liabilities at a specific point in time, while a full audit examines accounting policies, internal controls, and year-long financial statements, with the auditor taking legal and professional responsibility for its conclusions. Tether's prior reliance on quarterly attestations had drawn sustained skepticism from regulators, institutional investors, and market observers, who argued the format offered limited insight into reserve management, what qualified as an acceptable asset, and the robustness of internal accounting practices. The company pointed to governance changes as part of the shift. Simon McWilliams was appointed CFO in early 2025, a move Tether framed as bringing traditional finance experience to the role. CEO Paolo Ardoino and McWilliams have positioned the KPMG audit as central to Tether's assertion that all issued USDT tokens are 100% backed. An unqualified opinion provides third-party validation at a level the company had not previously secured. The development comes as stablecoin regulation in the U.S. continues to evolve. Policymakers have stepped up efforts to build a federal framework for dollar-pegged tokens, and a credible audit track record is widely seen as a baseline for firms seeking to operate under such rules. Circle, issuer of USDC, has long maintained more traditional audit practices, though USDC's market footprint remains significantly smaller than USDT's. With about $141 billion in U.S. Treasuries, Tether is also a meaningful participant in short-duration U.S. government debt markets. Audited confirmation that reserves exist, are properly custodied, and are correctly accounted for matters beyond crypto trading, touching the broader mechanics of dollar liquidity.
