WisdomTree and MoonPay Partner to Offer Tokenized Treasury Fund to 35 Million Accounts

Tokenized Treasury Fund Comes to MoonPay

WisdomTree and MoonPay announced on September 18, 2026, that they will build an access point letting U.S. investors buy shares of WisdomTree's tokenized government money market fund (ticker WTGXX) directly inside MoonPay's platform.

MoonPay will also use the fund to back its stablecoin business, placing the tokenized fund in its reserve management.

Key Numbers

• WTGXX held $1.23 billion, making it the fifth-largest tokenized Treasury product and the largest of WisdomTree's seven tokenized funds.
• The total tokenized Treasury market stood at $15.40 billion.
• MoonPay reports more than 35 million accounts and over 1,700 enterprise partners.
• No launch date was given for the MoonPay access point.

What the Companies Say

"Money moves differently today, and investing needs to keep pace," said Jonathan Steinberg, founder and CEO of WisdomTree. "Stablecoins are reshaping how people and businesses both hold and move value, and working with MoonPay as an access point can give eligible U.S. investors another path to deploy their assets into WTGXX."

Caroline D. Pham, CEO of MoonPay Institutional, said the work "demonstrates how financial innovation can enable better experiences for investors in U.S. regulated markets and products." Pham was acting chairman of the Commodity Futures Trading Commission before joining MoonPay.

Reserve Management Details

MoonPay will incorporate WTGXX into its stablecoin reserve management, meaning cash backing would be held in a fund whose shares are recorded onchain rather than only in bank deposits and bills at a custodian. The firms did not say what portion of reserves the fund would hold or which MoonPay stablecoin products would use it.

Second Money Market Fund Deal for MoonPay

MoonPay previously connected Franklin Templeton's tokenized government money market fund (BENJI) to its MoonPay Trade platform in June, aimed at institutional users. The new WisdomTree arrangement adds a reserve-management use on top of distribution.

WisdomTree's Wider Distribution Push

WisdomTree has been expanding its tokenized funds through the year. It extended them to Solana in January, and in April, DeFi lender Lotus took a WisdomTree money market fund into the reserves backing its lotusUSD, while Stable Sea placed WisdomTree tokenized Treasury yield in business operating cash.

What Is WTGXX?

WTGXX invests in U.S. Treasury obligations and money market securities, seeking current income while preserving capital and liquidity. The page listing the fund carries no performance history and describes it as new.
