Tether Hires Big Four Firm for First Full Audit of USDT Reserves

Key Facts

1Tether has officially engaged a Big Four accounting firm to conduct its first-ever full independent audit of USDT reserves.
2The move aims to address long-standing questions regarding the transparency of Tether's reserves and establish new disclosure standards.
3The announcement on March 24, 2026, marks a major industry shift after years of relying on limited attestation reports.

Tether officially announced on Tuesday, March 25, that it has engaged a Big Four accounting firm to conduct the first-ever comprehensive audit of its USDT reserves. The company described the upcoming engagement as the "biggest ever inaugural audit in the history of financial markets," highlighting the unprecedented scale of the process. This move directly addresses long-standing demands for transparency, a primary point of criticism that Tether has navigated for years while maintaining its market dominance. The audit is now viewed as a strategic pathway for USDT to potentially gain formal approval under the GENIUS Act, with reserves estimated between $184 billion and $192 billion. Market analysts suggest this step will mitigate systemic risks within the crypto ecosystem and help Tether counter growing competition from rivals like USDC. Ultimately, the audit represents a major milestone in Tether's efforts to secure institutional trust and long-term regulatory compliance.
