Tether announced a contract with a Big Four firm to conduct the first full audit of USDT reserves, totaling around 184 billion USD at the current level. Tether described this as the largest inaugural audit in financial market history.
Previously, Tether only published periodic attestation reports from BDO and had not conducted an independent full audit. Hiring a Big Four firm is seen as a major step after years of debate over USDT’s transparency and reliability.
KPMG is reported to be the main firm performing the audit. PwC was separately hired to improve internal systems and reporting before the official audit. The goal is to increase transparency, prepare for stricter US stablecoin regulations, and set a new quality standard for the digital asset market.
Tether had promised a full audit since 2017–2018 but only delivered attestation reports. The latest announcement was made on March 24, 2026. The final audit report is not yet available, only the announcement and prior attestation reports exist.
Official sources include Tether’s Transparency page and the Tether website announcement about signing a Big Four firm to complete the first full audit.
