"Trust is built when institutions are willing to open themselves fully to scrutiny. This audit represents years of work to strengthen our systems so that Tether can meet the highest standards applied in global finance." — Paolo Ardoino, CEO, Tether
Tether, issuer of the $184 billion USDT stablecoin, hired KPMG on March 27 to conduct its first full financial statement audit — ending a nine-year stretch during which the world's dominant stablecoin operated without one. PricewaterhouseCoopers has been engaged simultaneously to prepare internal controls and systems infrastructure ahead of the review. The dual Big Four engagement marks Tether's most significant transparency commitment since its $18.5 million settlement with the New York Attorney General in 2021.
The audit is not voluntary. The GENIUS Act, signed into law in July 2025, requires stablecoin issuers with more than $50 billion in outstanding liabilities to submit annual financial statement audits performed by a PCAOB-registered firm. Tether, with $184 billion in circulation, exceeds that threshold by a factor of 3.7x. Simultaneously, Tether launched USAT — a separate, GENIUS Act-compliant stablecoin issued through federally chartered Anchorage Digital Bank — in January 2026, signaling a two-product strategy to retain both offshore and U.S. market share.
The stakes extend well beyond Tether's corporate compliance. USDT settles an estimated $10 trillion in annual on-chain volume. Its reserves include $135–141 billion in U.S. Treasuries, making Tether one of the largest holders of U.S. government debt globally. Whether KPMG's audit reveals the same picture as BDO Italia's quarterly attestations — or something materially different — will have implications across stablecoin markets, DeFi collateral structures, and the broader regulatory posture toward dollar-pegged digital assets.
The GENIUS Act establishes tiered oversight for stablecoin issuers. Issuers with $10 billion or less in outstanding stablecoins may opt for state-level regulation, provided the state framework is "substantially similar" to federal standards. On April 1, 2026, the Treasury Department published its first notice of proposed rulemaking to define that equivalence test, with a 60-day public comment window.
For issuers above $50 billion — a category that currently includes only Tether (USDT at $184 billion) and Circle (USDC at $78 billion) — the requirements are more stringent. These entities must produce annual financial statements audited by a PCAOB-registered firm, maintain 1:1 reserve backing with qualifying assets, publish monthly reserve reports certified by both CEO and CFO, and comply with full AML/KYC obligations.
The law does not specify a deadline for the first audit cycle, but market participants and legal commentators expect enforcement actions to begin in late 2026 or early 2027. Tether's engagement of KPMG in March 2026 positions the company to have audited statements available well ahead of any enforcement timeline, according to the company's public statements.
KPMG's scope, as reported by the Financial Times and confirmed by Tether, covers:
PwC's parallel engagement focuses specifically on preparing Tether's internal controls and systems to meet audit-readiness standards. This dual-firm approach is common in situations where a company has not previously undergone a full audit and needs to establish baseline controls documentation.
No timeline for completing or publishing the audited statements has been made public. Full audits involving crypto-native assets and multi-chain tokenized liabilities typically take several months, according to industry accounting professionals.
Since July 2022, Tether has published quarterly attestations prepared by BDO Italia under the International Standard on Assurance Engagements (ISAE) 3000. These provide "limited assurance" — also called "negative assurance" — meaning BDO certified that nothing came to their attention suggesting the reserves were misstated.
This is materially different from an audit. As The Wall Street Journal reported, attestations are "snapshots of a company's assets held at one moment in time with less rigorous standards than audits." An audit requires examining transactions over a full reporting period, testing internal controls, verifying asset existence and valuation through independent confirmation, and issuing a positive assurance opinion.
The distinction matters because Tether's history includes documented periods of reserve inadequacy. The 2021 NYAG settlement found that Tether sometimes held no reserves backing its stablecoin, had no access to banking from mid-2017, and misrepresented its liquidity position to clients. Tether neither admitted nor denied these findings as part of the $18.5 million settlement. The company also paid a $41 million fine to the CFTC in October 2021 for making untrue or misleading claims about USDT reserves.
BDO's most recent attestation (Q3 2025, covering September 30, 2025) reported total reserves of $181.2 billion against USDT in circulation. The composition showed 82% in U.S. Treasuries, 10% in money market funds, and 5% in repurchase agreements, with the remainder in gold, Bitcoin, and other investments. These figures have not been independently verified through a full audit process — until now.
Tether reported net profit exceeding $10 billion for full-year 2025, down 23% from $13 billion in 2024, according to Bloomberg. The decline came despite a 37% increase in USDT issuance during the year — Tether issued nearly $50 billion in new USDT in 2025, pushing total circulation to $186.5 billion at year-end.
The profit decline is attributable to lower average Treasury yields in the second half of 2025, as the Federal Reserve began its easing cycle. Tether's revenue derives primarily from returns on U.S. Treasuries held in reserve. With $141 billion in Treasury exposure at year-end, even modest yield compression produces large absolute declines in revenue.
The company reported $6.3 billion in excess reserves — capital held above the 1:1 backing requirement — representing a 3.4% buffer. While meaningful in absolute terms, this buffer is thin relative to the systemic role USDT plays in crypto markets. Tether's custodial relationship with Cantor Fitzgerald provides access to primary dealer Treasury trading, which facilitates large-scale reserve management.
Tether remains privately held. It has no publicly filed financial statements, no SEC reporting obligations (outside the GENIUS Act's emerging requirements), and no independent board of directors. According to Bloomberg, the company was exploring a fundraising round in early 2026, though terms and structure were not disclosed.
On January 27, 2026, Tether launched USAT (USA₮), a separate dollar-backed stablecoin issued through Anchorage Digital Bank, N.A. — a federally chartered, OCC-regulated digital asset bank. Unlike USDT, which is issued by Tether Limited (a British Virgin Islands entity), USAT operates entirely within the U.S. federal regulatory perimeter.
Key structural differences between USDT and USAT:
| Feature | USDT | USAT | |---------|------|------| | Issuer | Tether Limited (BVI) | Anchorage Digital Bank (U.S.) | | Regulator | None (historically) / GENIUS Act | OCC | | Reserve custodian | Cantor Fitzgerald | Cantor Fitzgerald | | GENIUS Act status | Must comply as existing issuer | Designed for compliance | | CEO | Paolo Ardoino | Bo Hines (former White House Crypto Council) |
USAT launched with exchange support from Kraken, OKX, and Crypto.com. Market capitalization data for USAT is not yet widely tracked on major aggregators, suggesting circulation remains limited in its first 10 weeks.
The dual-product approach allows Tether to serve the offshore USDT market — which dominates emerging-market remittances and non-U.S. exchange trading — while building a separate, compliance-first product for the U.S. institutional market. Whether the two products cannibalize each other or expand Tether's total addressable market remains to be seen.
Tether's audit comes against a backdrop of shifting stablecoin market dynamics. Total stablecoin supply reached $315 billion in Q1 2026, according to industry data. USDT and USDC together account for 93% of the market.
However, the growth rates are diverging. USDC supply hit $78 billion, up 220% since late 2023, driven by B2B settlement integrations with Visa and Stripe. USDC now leads USDT in transaction activity on certain metrics, even as USDT maintains a 2.4x lead in circulating supply.
Circle, USDC's issuer, has operated under more transparent conditions for years — publishing monthly attestations from Grant Thornton (and later Deloitte) and maintaining U.S.-based operations. Circle filed for an IPO in January 2024, providing additional financial disclosure through SEC filings.
The competitive pressure is real. If KPMG's audit confirms Tether's reported reserve composition and produces a clean opinion, it may neutralize Circle's transparency advantage. If the audit reveals material discrepancies — however unlikely given years of consistent attestation data — the market share implications would be significant.
USDT's role in crypto markets is difficult to overstate. According to Tether's own data, it settles trillions of dollars in annual on-chain volume. USDT serves as the primary trading pair on most non-U.S. exchanges, the dominant stablecoin for DeFi collateral, and the leading vehicle for cross-border remittances in emerging markets.
A disorderly loss of confidence in USDT — triggered, for example, by a qualified audit opinion or material restatement — would cascade through DeFi lending protocols, exchange liquidity pools, and cross-border payment corridors simultaneously. The IMF flagged tokenized finance systemic risks in a recent report, and stablecoin concentration was identified as a primary concern.
The GENIUS Act's audit requirement is, in part, a regulatory response to this systemic exposure. By forcing Tether to submit to Big Four scrutiny, U.S. regulators aim to either validate the reserves or surface problems while resolution mechanisms can still be deployed.
Tether's KPMG engagement is the most consequential transparency event in stablecoin history. For nine years, the largest stablecoin operated on attestations, settlements, and assurances. The GENIUS Act has changed the calculus — full audits are no longer optional for issuers at Tether's scale.
The outcome matters for the entire digital asset ecosystem. A clean audit opinion would validate Tether's reserve claims and potentially strengthen USDT's market position. Anything less would force a rapid reassessment of counterparty risk across every protocol, exchange, and payment corridor that depends on USDT liquidity.
The data will speak for itself. The question is when. Tether has disclosed no timeline for publication. Markets, regulators, and competitors are waiting.
