Fact Check
The primary attestation report from Anchorage Digital Bank (USAT's federally regulated issuer), signed May 27, 2026, confirms 140,850,950 USAT tokens outstanding as of April 30, 2026. Compared to ~22.1 million tokens in the prior month (per CryptoBriefing and The Block reporting), this represents a ~537-540% month-over-month increase, matching the claim. Three independent outlets (The Block, CoinDesk, CryptoBriefing) report the same ~540% MoM figure and consistent reserve numbers ($141.2M).
Summary

Tether said its U.S.-focused stablecoin USAT increased nearly 540% month over month, rising from about 22 million tokens in March to more than 140 million in April, according to a Thursday attestation. Total reserves reached $141,178,400, leaving a reported surplus of $327,450 over outstanding redeemable tokens. The report says USAT launched in January as Tether’s effort to operate within the U.S. regulatory perimeter and to align with GENIUS Act-style requirements for 1:1 backing with cash or high-quality liquid assets. USAT is issued by Anchorage Digital Bank, which is regulated by the OCC, and its reserves consist of $13,427,400 in cash and $127,751,000 in reverse repurchase agreements backed by U.S. Treasury securities and held in segregated fiduciary trust accounts. Tether CEO Paolo Ardoino said the figures show accelerating adoption of regulated digital dollars as U.S. stablecoin rules become clearer.

Terms & Concepts
  • GENIUS Act: A U.S. stablecoin legislative framework referenced in the report as setting reserve and compliance standards such as 1:1 backing with cash or high-quality liquid assets.
  • Stablecoin: A cryptocurrency designed to track a stable value, typically by being backed by fiat currency or highly liquid reserve assets.
  • Reverse repurchase agreements: Short-term transactions in which cash is invested against securities collateral; here they are backed by U.S. Treasury securities as part of USAT reserves.
