"This is a defining moment for the stablecoin industry." — Paolo Ardoino, CEO, Tether
KPMG U.S. issued an unqualified opinion on Tether International S.A. de C.V.'s 2025 financial statements on August 13, 2026, marking the first full financial-statement audit of the $183 billion USDT issuer by a Big Four accounting firm. The audit confirmed reserves exceeded liabilities by $6.814 billion as of December 31, 2025, across a balance sheet anchored by $141 billion in U.S. Treasury exposure, 146 tonnes of physical gold, and approximately 99,000 bitcoin valued at $5.8 billion at year-end.
The audit replaces a regime of quarterly attestations provided by BDO Italia since 2021 and addresses a criticism that has followed Tether since its 2014 founding: the absence of independently verified, GAAP-compliant financial statements. Three material gaps remain. The full audit report, including notes and key audit matters, has not been publicly released. The audit covers only the issuing entity, not Tether's parent holding structure. And USDT's reserve composition — specifically its gold and bitcoin holdings — does not conform to pending U.S. and EU regulatory frameworks, raising questions about the token's eligibility on regulated platforms after 2027.
KPMG was engaged in March 2026 through a competitive selection process, replacing BDO Italia's quarterly attestation role. The engagement covered the fiscal year ending December 31, 2025, and was conducted under U.S. Generally Accepted Accounting Principles (GAAP) and American Institute of Certified Public Accountants (AICPA) professional standards — the same framework governing public company audits in the United States.
The scope extended beyond headline reserve figures. According to Tether, KPMG examined the full balance sheet, income statement, and cash flow statement, along with transactions, internal systems, asset valuations, counterparty relationships, and ownership records. The audit procedures included physical inspection of Tether's gold reserves: KPMG counted and verified each individual gold bar's existence and identifying information rather than relying solely on custodian reports.
CFO Simon McWilliams, who joined Tether in early 2025 specifically to build the internal finance infrastructure required for a full audit, called the result "a landmark moment for Tether and for the industry we serve."
An unqualified opinion — meaning no reservations, exceptions, or caveats — is the most favorable outcome an independent auditor can deliver. It indicates that, in KPMG's professional judgment, the financial statements fairly present the company's position in all material respects.
The audited figures confirmed the following reserve structure as of December 31, 2025:
| Asset Class | Amount | Notes | |---|---|---| | U.S. Treasuries (direct + reverse repos) | ~$141B | Largest single allocation; positions Tether among top global holders of U.S. government debt | | Physical Gold | 146 tonnes | Physically inspected and counted by KPMG | | Bitcoin | ~99,000 BTC (~$5.8B) | Valued at year-end prices | | Excess Reserves (surplus over liabilities) | $6.814B | Buffer between total assets and total liabilities |
The reserve surplus of $6.814 billion at December 31, 2025 deserves contextual scrutiny. BDO's June 30, 2026 quarterly attestation reported that same buffer at $4.11 billion — a 40% contraction in six months. During the same period, USDT circulation grew from approximately $144 billion to $184 billion. The shrinking buffer relative to expanding supply is a metric worth monitoring, though Tether has not publicly attributed the decline to any specific factor.
Tether reported net profits exceeding $10 billion for fiscal year 2025, though this represented a 23% decline from approximately $13 billion in 2024, even as total assets rose by more than $49 billion. The profit primarily derives from interest earned on the U.S. Treasury portfolio.
In 2025, Tether issued nearly $50 billion in new USDT — the second-largest annual issuance in its history. Total USDT in circulation surpassed $186 billion at its peak before contracting to approximately $183 billion by mid-August 2026. That $5.4 billion market cap decline over 60 days, from a peak near $190 billion in May, reflects broader market conditions rather than specific redemption pressure.
Tether generated $1.5 billion in net operating profit during Q2 2026 alone, according to its most recent quarterly attestation. The company remains privately held and is not subject to public reporting requirements.
Tether's transparency trajectory has been shaped as much by enforcement as by voluntary disclosure:
The transition from quarterly attestation to full audit represents a material upgrade in transparency methodology. An attestation examines specific assertions (e.g., "do reserves equal or exceed liabilities at this date?"). An audit examines the entire financial reporting framework — accounting policies, internal controls, related-party transactions, contingencies, and going-concern assumptions.
Despite the audit milestone, analysts and transparency advocates have identified three structural limitations:
1. The full report has not been published. Tether announced the unqualified opinion and disclosed headline figures but has not released the complete audit report, including notes to financial statements, key audit matters, and related-party disclosures. Without these materials, independent verification of KPMG's findings is limited. For comparison, public companies must file complete audited financials with the SEC.
2. Entity-level scope. The audit covers Tether International S.A. de C.V. — the USDT issuing entity — but not the broader Tether Holdings group structure. An investigation by the International Consortium of Investigative Journalists has previously highlighted opacity around Tether's corporate ownership and intercompany relationships. No audit of the parent entity has been announced.
3. The audit does not address operational resilience. An unqualified opinion confirms that financial statements are fairly presented. It does not evaluate redemption capability under stress conditions, counterparty concentration risk, or liquidity under rapid withdrawal scenarios. These are the questions most relevant to USDT holders during periods of market distress.
The audit arrives at an inflection point in stablecoin regulation. Two frameworks are converging that could constrain USDT's market access:
GENIUS Act (United States): Signed into law, the Act requires stablecoin issuers to maintain 1:1 reserves in fiat currencies, short-term U.S. Treasuries, and similar liquid assets. Gold and bitcoin — which constitute a material portion of Tether's reserves — do not qualify under these provisions. Monthly attestations from independent auditors, certified by the CEO and CFO, are mandated. Core requirements take effect by January 2027 or 120 days after final implementing regulations are issued, whichever comes first.
MiCA (European Union): The Markets in Crypto-Assets regulation, in full enforcement since mid-2026, classifies dollar-pegged stablecoins as e-money tokens. Issuers must hold banking-grade licenses, maintain full fiat reserves in segregated accounts at approved financial institutions, and submit to regular audits. Tether's reserve structure, with its gold and bitcoin allocations, does not conform to MiCA's e-money token requirements.
The practical implication: if Tether does not restructure its reserves to exclude non-qualifying assets, USDT may lose eligibility for distribution on U.S. regulated platforms by mid-2027 and has already faced restrictions in the EU. The audit itself — while a transparency milestone — is not a compliance event. The distinction between "audited" and "compliant" is the key risk factor for USDT's continued market access.
The stablecoin transparency hierarchy as of August 2026:
| Issuer | Token | Market Cap | Auditor | Frequency | Scope | |---|---|---|---|---|---| | Tether | USDT | ~$183B | KPMG (annual audit); BDO (quarterly attestation) | Annual + quarterly | Issuing entity only | | Circle | USDC | ~$57B | Deloitte | Monthly attestation + annual audit | Full corporate entity; CUSIP-level security detail | | Paxos | USDP/PYUSD | ~$5B | WithumSmith+Brown | Monthly attestation | Regulated trust company; NY DFS supervised |
Circle's USDC maintains the highest-frequency disclosure regime: monthly Deloitte attestations, weekly reserve updates, daily SEC filings (as a public company since April 2024), and security-level detail identifying individual Treasury holdings by CUSIP. Tether's move to annual KPMG audits narrows but does not close this gap.
The competitive dynamic matters because the Coinbase-Circle USDC distribution agreement — under which Coinbase earns 100% of reserve interest on platform-held USDC and 50% on external USDC — renewed on existing terms in August 2026 through 2029. Coinbase's parallel endorsement of Open USD, a rival stablecoin project, in June 2026 signals that distribution economics, not just transparency, will determine stablecoin market share.
Tether's KPMG audit resolves the most persistent criticism leveled at the company over the past decade: the absence of independently verified financial statements prepared under recognized accounting standards. With $183 billion in circulation and over $10 billion in annual profit, the audit subjects the world's most systemically important stablecoin to a level of scrutiny that the industry and its regulators have demanded for years.
The audit does not, however, resolve the three questions that will determine USDT's trajectory in 2027 and beyond. First, whether Tether will restructure reserves to comply with GENIUS Act and MiCA requirements. Second, whether the company will publish the full audit report or continue to disclose only headline figures. Third, whether the 40% contraction in the reserve buffer between December 2025 and June 2026 reflects a structural shift or a transient market condition.
The data shows a company that has made a material step toward institutional-grade transparency while remaining outside the regulatory perimeter that its largest competitors have already entered. The market will ultimately price the difference.
