WisdomTree and MoonPay announced a partnership on Thursday to expand US investor access to the WisdomTree Treasury Money Market Digital Fund (WTGXX), a tokenized money market mutual fund designed to maintain a $1 share price. The collaboration leverages MoonPay’s technology to create an access point for WTGXX, granting WisdomTree entry to MoonPay’s network of more than 35 million accounts. Additionally, MoonPay plans to integrate WTGXX into its stablecoin reserve management stack, supporting its enterprise stablecoin business launched in November 2025.

The arrangement highlights growing institutional interest in tokenized assets, with the broader tokenized US Treasury market valued at approximately $15.4 billion as of Thursday. WTGXX currently accounts for about $1.23 billion of this total and has recorded net flows of $466 million over the past 30 days, according to RWA.xyz data. This performance contrasts with other funds like Ondo U.S. Dollar Yield (USDY), which saw positive net flows of $66 million during the same period. WisdomTree, managing roughly $176.7 billion in assets, indicated that the collaboration could extend to additional tokenized funds and international markets.
