Tether, the El Salvador-based company behind the world's largest stablecoin, has completed its first full independent audit by a Big Four accounting firm. KPMG U.S. issued an unqualified opinion on Tether International's financial statements for the year ending December 31, 2025, confirming that reserves exceeded liabilities by $6.8 billion.
The audit, announced August 13, 2026, marks a watershed moment for a company that spent years facing skepticism about whether its dollar-backed tokens were fully supported by reserves. Tether has issued approximately $183 billion in USDT tokens pegged to the U.S. dollar.
Why This Matters
For years, critics questioned whether Tether actually held enough assets to back every USDT token in circulation. The company previously published quarterly "attestations" by BDO Italia, which verified reserve sizes but stopped short of a full financial audit. The distinction matters: attestations confirm balances at a point in time, while an audit examines transactions, systems, ownership records, valuations, counterparties, and underlying evidence.
A Big Four audit from KPMG carries significantly more weight than attestations. It represents the highest level of assurance available in financial reporting, requiring KPMG to verify not just the final numbers but the processes and controls that produced them.
The Numbers
According to Tether, the audited financial statements for 2025 show:
- $6.8 billion surplus — reserves exceeded liabilities by this amount
- $183 billion in USDT tokens issued
- $141 billion in total reserves confirmed
- KPMG physically counted every gold bar Tether held as part of its reserves
Tether's reserves include U.S. Treasuries, dollar-denominated assets, and gold. The $6.8 billion surplus means Tether holds approximately 3.7% more in reserves than required to back every USDT token in circulation.
What KPMG Examined
Tether said the audit went far beyond simple balance verification. KPMG examined transactions, systems, ownership records, valuations, counterparties, and underlying evidence supporting the company's financial statements. The firm physically counted every gold bar in Tether's reserves, a level of scrutiny that goes well beyond the quarterly attestations Tether had previously published.
A KPMG spokesperson confirmed the engagement: "We can confirm that we issued an unqualified opinion on Tether International, S.A. de C.V.'s financial statements in accordance with AICPA standards for the year ending December 31, 2025. Due to client confidentiality, we have no further comment."
An "unqualified opinion" is the best possible outcome — it means KPMG found no material issues with Tether's financial statements.
Years of Promises
Tether has for years said it would seek a full audit. The company faced intense scrutiny after the 2022 collapse of FTX, which had also lacked audited financial statements. Critics argued that Tether's opaque reserve structure posed systemic risk to the crypto market, given that USDT is used as collateral across virtually every major exchange and DeFi protocol.
The company's previous attestations by BDO Italia provided limited assurance — confirming that reserves existed at a given snapshot but not auditing the full financial system behind them. The jump to a KPMG audit represents a significant upgrade in transparency.
GENIUS Act Pressure
The audit also comes as new U.S. stablecoin legislation takes effect. The GENIUS Act, which establishes federal oversight for payment stablecoins, requires issuers to maintain audited reserves and comply with banking-style regulations. Tether's KPMG audit positions the company ahead of these requirements and signals its intent to operate within the new regulatory framework.
For Tether, compliance with the GENIUS Act is not optional. The law requires stablecoin issuers to obtain audited financial statements, maintain reserves in approved assets, and submit to regular examination. Tether's proactive audit suggests the company is preparing for full regulatory compliance rather than fighting it.
Market Reaction
The audit announcement was met with cautious optimism in crypto markets. Bitcoin traded near $63,300 on August 18, recovering from weekly losses tied to $390 million in ETF outflows. USDT's market capitalization remained stable at approximately $183 billion, showing no signs of investor concern about the token's backing.
Tether CEO Paolo Ardoino said in a statement: "For years, some detractors said an audit of Tether could not be completed." The completion of the KPMG audit effectively closes a chapter that has hung over the company since its founding.
Bottom Line
Tether's KPMG audit is a landmark moment for crypto transparency. A $6.8 billion surplus confirmed by a Big Four firm should put to rest years of speculation about USDT's backing. The bigger question now is whether other stablecoin issuers will follow suit — and whether Tether can maintain this level of transparency going forward under GENIUS Act requirements.
