Tether released its Q1 2026 attestation report on March 31, revealing $1.04 billion in net profit and USDT circulation at record levels, with reserves audited by BDO, a top-five global accounting firm. The stablecoin issuer’s financial performance arrives amid intensifying regulatory pressure, including a Senate probe launched by Senator Warren and a $344 million USDT freeze coordinated with US authorities one week prior.
Reserve Transparency Under Big Four Scrutiny
The attestation report demonstrates Tether’s reserve composition as of March 31, 2026, with $183 billion in total token-related liabilities backed by diversified assets. US Treasury bills account for $141 billion in direct and indirect exposure, positioning Tether as the 17th largest holder of US government debt. Physical gold holdings total $20 billion, while Bitcoin reserves stand at $7 billion. BDO’s engagement follows previous audit announcements involving KPMG and PwC, signaling Tether’s effort to maintain institutional credibility amid regulatory headwinds.
Profit Surge Amid Record USDT Circulation
USDT circulation reached all-time highs in April 2026, with the stablecoin adding more than 5 billion tokens to circulation during the quarter. The $1.04 billion quarterly profit reflects Tether’s dominance in the stablecoin market, where USDT remains the primary liquidity vehicle across crypto exchanges and DeFi protocols. The broader crypto market capitalization stood at $2.5 trillion as of Friday, underscoring the material role USDT plays in market infrastructure and trading volume.
Regulatory Pressure Intensifies on Stablecoin Operator
Tether faces mounting scrutiny from US lawmakers and law enforcement. Senator Warren initiated a regulatory probe, while Commerce Secretary Lutnick’s involvement signals executive-branch focus on stablecoin compliance. The $344 million USDT freeze and earlier $4.2 billion crypto seizure demonstrate authorities’ willingness to take direct action. CEO Paolo Ardoino emphasized Tether’s commitment to operational resilience: “The focus is on keeping the structure simple, liquid, and resilient by design, so it does not depend on favorable environments or external support.” These measures underscore the tension between stablecoin innovation and regulatory control.
What Happens Next
The outcome of Senator Warren’s probe remains undefined. Tether’s launch of “The People’s Wallet” self-custody application signals expansion into retail adoption despite regulatory headwinds. Q2 2026 attestation results and any further enforcement actions will determine whether current reserve levels and profitability can be sustained under tightened compliance frameworks.
