WisdomTree Tokenized Treasury Fund Wins SEC Approval for 24/7 Trading
WTGXX is WisdomTree’s tokenized U.S. Treasury money market fund, registered under the Investment Company Act of 1940, with its shares circulating on a blockchain. Traditional mutual funds are constrained by business hours and net asset value calculation schedules and generally cannot trade around the clock. Allowing a regulated fund to enter a 24/7 secondary market is therefore an important Wall Street test of using on-chain assets for cash management.
On February 24, 2026, the SEC granted WisdomTree an exemptive order, while FINRA authorized WisdomTree Securities to provide liquidity for WTGXX through a dealer-principal model. The fund trades at $1 per share and offers instant on-chain settlement via USDC to institutional clients of WisdomTree Connect. As of April 28, it had about $858 million in assets and a seven-day annualized yield of approximately 3.43%.

The history behind this eventStable Sea Integrates WisdomTree Tokenized Treasury Fund to Improve Corporate Cash Management
Stable Sea is a corporate treasury management startup. Its addition of WTGXX, WisdomTree's tokenized U.S. Treasury money market fund, allows companies to move idle cash into a low-risk, yield-bearing asset settled through blockchain infrastructure. This can reduce the opportunity cost of leaving funds for extended periods in low-interest bank accounts.
Stable Sea recently announced that it will integrate WTGXX into its platform, allowing corporate clients to allocate funds directly to the tokenized Treasury fund while managing both liquidity and yield. Reports did not disclose a formal launch date, the value of the partnership, the minimum investment threshold or the fund's current yield. Its performance will depend on redemption efficiency and corporate adoption.
