Tether, the issuer of the world’s largest stablecoin USDT, announced Thursday that it has completed its first-ever full financial audit, a milestone the company spent years promising while critics demanded the same level of scrutiny common among major financial institutions. KPMG U.S., one of the four giant accounting firms that audit most of the globe’s biggest corporations, delivered an unqualified opinion on Tether International’s financial statements for the year ended December 31, 2025, confirming that the company’s books fairly presented its financial position under U.S. generally accepted accounting principles.
The audit represents a dramatic escalation from the quarterly reserve attestations Tether has relied upon since settling an earlier investigation with the New York Attorney General’s office. Whereas an attestation only checks the amount and composition of reserves on a given date, a full audit tests transactions, systems, valuations, counterparties and ownership records — and, in Tether’s case, included auditors physically counting and inspecting the company’s gold bars in person. A KPMG U.S. spokesperson confirmed to reporters that the firm issued the unqualified opinion, declining further comment due to client confidentiality.
What Tether’s numbers actually show
The audited statements showed Tether’s reserves exceeded its liabilities by $6.814 billion at year-end 2025, a surplus that helps explain how USDT, a token pegged one-to-one to the U.S. dollar, has retained broad market confidence even as its supply ballooned past $180 billion in circulation. The scale matters: Tether is now among the largest holders of U.S. government debt in the world, a fact that puts its reserve management squarely inside the conversation about systemic stability in both crypto and traditional finance.
A financial audit, unlike a snapshot attestation, requires auditors to gather evidence supporting every line item across the balance sheet, income statement and cash flow statement. KPMG’s testing reportedly spanned the full breadth of Tether’s operations, including the storage, valuation and authenticity of physical gold bars held as part of the reserve mix — an unusual requirement born out of longstanding skepticism about what exactly backs USDT.
Why the skepticism lasted so long
For nearly a decade, Tether answered questions about USDT’s backing with quarterly attestations produced by smaller, less prominent accounting firms. Critics argued that a company managing more than $180 billion in tokenized claims — and indirectly financing a sizable chunk of the short-term U.S. Treasury market — should be subject to the same audit regime as any other financial institution of comparable size. The complaint became such a recurring theme in crypto debates that it earned its own shorthand: “Tether FUD,” a phrase used dismissively by supporters and pointedly by skeptics.
Behind the slogan sat a real concern. Because USDT functions as critical trading infrastructure across most major crypto exchanges, a sudden loss of confidence in its dollar peg could trigger cascading liquidations across digital asset markets. Regulators and analysts have repeatedly flagged USDT as a potential systemic risk vector for the broader crypto economy, a worry that only intensified as the token’s market cap climbed from a few billion dollars in 2020 to its present scale. Completing a Big Four audit was, for years, presented by Tether as the definitive rebuttal to that line of criticism.
The shift from attestation to audit
Tether revealed in March that it had engaged a Big Four firm to conduct the audit, though it declined at the time to name the partner. The decision signaled that the company was finally prepared to open its books to the kind of testing reserved for publicly listed corporations and major banks. KPMG’s role puts Tether inside the same tier of audited entities as some of the world’s largest banks, insurers and asset managers.
Ardoino, in his statement accompanying the announcement, framed the milestone as a long-overdue answer to doubters. “For years, some detractors said an audit of Tether could not be completed,” the CEO said, casting the unqualified opinion as proof that the operation could withstand full-scale professional scrutiny. The statement positions the audit as both a defensive milestone and a marketing tool, the kind of credential the company can lean on as it courts institutional partners and seeks broader mainstream legitimacy.
What remains unresolved
Despite the unqualified opinion, several questions persist. Tether has not yet publicly released KPMG’s full findings, and reporters have asked whether the company intends to share the underlying audit report, a standard practice for entities seeking to convert an audit into a trust-building event. The opinion itself only affirms that the financial statements fairly present the company’s position; it does not, by itself, guarantee that the reserves are liquid, that every counterparty is sound, or that gold valuations are immune to market shocks.
Regulatory posture may also evolve. With a Big Four audit now on file, U.S. and European regulators who have watched USDT with varying degrees of suspicion gain a new data point to weigh in ongoing discussions about stablecoin oversight. Policymakers drafting stablecoin legislation have argued for years that issuers should be subject to prudential standards similar to those imposed on money market funds; an unqualified audit arguably strengthens Tether’s hand in those conversations, even if it does not satisfy every demand made of fully regulated banks.

- Result: Unqualified opinion; reserves exceed liabilities by $6.814 billion
- Token: USDT, market cap above $180 billion
- Quote: CEO Paolo Ardoino on completing the long-promised audit
Stablecoin scrutiny enters a new phase
Tether’s transition from quarterly attestation to full audit marks the most significant credibility test the company has passed since launching USDT in 2014, and it resets the baseline of what regulators, counterparties and crypto traders should expect from a stablecoin issuer of its size.
The audit closed one chapter in the long-running battle over USDT’s credibility, but it does not settle the broader policy debate about how digital tokens that mimic fiat currency should be governed, monitored and reserved. For now, Tether has the report it spent years promising, a clean opinion from a global accounting giant and a multibillion-dollar reserve cushion to point to. The next round of scrutiny will determine whether Tether converts that audit into something more durable: a structural position inside the regulated financial system, or simply a defensive shield used to fend off the next wave of stablecoin skepticism.
