Tether, the world’s largest stablecoin issuer, announced it has formally engaged a Big Four accounting firm to conduct its first full independent financial statement audit, marking a major step toward greater transparency in the digital asset industry.
The audit, which will cover a complex mix of digital assets, traditional reserves, and tokenized liabilities, is expected to be one of the largest inaugural audits ever conducted in financial markets.

With USD₮ (USDT) market capitalization exceeding $184 billion and more than 550 million users globally, the move signals Tether’s effort to strengthen trust in its reserves and operational structure. A full audit by a Big Four firm represents one of the most rigorous forms of financial verification, going beyond the attestation reports that stablecoin issuers typically provide.
Historically, Tether has relied on quarterly attestations rather than full audits, a practice that has drawn scrutiny from regulators and market participants. These attestations provide snapshots of reserves at specific points in time but do not offer the same level of assurance as comprehensive audits.
Tether just released its quarterly attestation for Q4 2025.
Tether had a great year, surpassing 10B in profits.
USDT expanded throughout the year by 50 billion, because global demand for dollars is increasingly moving outside traditional banking rails, particularly in regions… https://t.co/RMkIvQC9uY

Tether said the onboarding process for the audit began weeks ago, with accounting firms reviewing its internal controls, financial reporting, and governance structure. The company noted that several firms expressed interest due to the scale and systemic importance of USDT within global crypto markets.
CEO Paolo Ardoino described the move as a long-term effort to strengthen institutional credibility.
“Trust is built when institutions are willing to open themselves fully to scrutiny,” Ardoino said, adding that the audit is designed to deliver “accountability, resilience, and confidence” for users relying on USDT.
The audit initiative comes after years of questions surrounding Tether’s reserves and transparency.
Tether has never completed a full independent audit of USDT reserves, despite repeated commitments to do so. This absence has been a persistent concern given the stablecoin’s central role in crypto liquidity and trading.
In 2021, Tether reached an $18.5 million settlement with the New York Attorney General following allegations that the company misrepresented its reserve backing. While Tether did not admit wrongdoing, the case intensified calls for greater transparency.
Additionally, Tether has previously faced scrutiny over:
These concerns were reflected in S&P Global’s downgrade of USDT’s transparency rating, citing limited disclosure and exposure to higher-risk assets within reserves.
Despite these issues, USDT has continued to dominate the stablecoin market and remains critical to global crypto liquidity.
Tether has taken several steps in recent years to prepare for a full audit. The company appointed Chief Financial Officer Simon McWilliams in 2025, strengthening internal financial controls and governance structures.
The company also reported strengthening reserves, improving liquidity management, and retaining earnings to support stablecoin stability. Tether noted that these funds, held within affiliated entities, provide additional balance sheet flexibility.
According to Tether, the audit will provide full visibility into:
The audit could mark a turning point for the stablecoin industry, where transparency standards have varied widely.
Stablecoins such as USDC and others already publish regular disclosures, but full Big Four audits remain rare across the sector. Tether’s move could set a precedent for institutional-grade transparency and regulatory readiness.
The development also comes as stablecoins become increasingly important in global finance, particularly for:
Tether framed the audit as part of its broader mission to support global financial access and digital dollar infrastructure. With hundreds of millions of users and growing institutional adoption, the company aims to position USDT as a trusted digital financial foundation.
If completed successfully, the audit could represent one of the most significant transparency milestones in stablecoin history and potentially reshape expectations for the entire digital asset industry.
