WisdomTree and MoonPay announced a strategic collaboration on September 17, 2026, designed to broaden U.S. investor access to the WisdomTree Treasury Money Market Digital Fund, known as WTGXX. Under the arrangement, MoonPay’s technology platform will serve as a distribution access point for the tokenized money market mutual fund, which seeks to maintain a stable $1.00 share price.

The partnership also calls for MoonPay to incorporate WTGXX into its own stablecoin reserve management. MoonPay, which provides infrastructure for transferring value between fiat currencies and digital assets, launched its enterprise stablecoin business in November 2025. The firm issues dollar-denominated stablecoins across multiple blockchains, backed by U.S. dollars and other high-quality liquid assets held in segregated accounts.

Access Through a Large User Network

WisdomTree stated that the collaboration gives the firm a direct connection to MoonPay’s network of more than 35 million accounts and more than 1,700 enterprise partners. The move creates an additional channel for eligible U.S. investors beyond WisdomTree’s existing broker-dealer pathway through WisdomTree Securities, Inc., a FINRA member.

MoonPay is not acting as a broker-dealer or investment adviser with respect to WTGXX. The fund remains under WisdomTree’s regulatory and compliance structure. MoonPay holds a New York BitLicense, a New York Limited Purpose Trust Charter, money transmitter licenses in multiple U.S. states, and MiCA authorization in the European Union, which supports the operational integration within existing financial rules.

Steinberg added that the objective is making tokenized funds a practical component of investor portfolio management.

Fund Scale and Market Context

According to data from RWA.xyz, the tokenized U.S. Treasury market stood at approximately $15.4 billion at the time of the announcement. WTGXX accounted for about $1.23 billion of that total. Over the prior 30 days, the fund recorded $466 million in net flows, measured as the difference between tokens minted and tokens burned. The Ondo U.S. Dollar Yield fund was the only other tokenized Treasuries product cited with positive net flows in the same period, at $66 million.

WisdomTree manages approximately $176.7 billion in assets under management globally. The firm indicated that the current collaboration could expand to additional tokenized funds, including opportunities in markets outside the United States.

Investment Structure and Risk Disclosures

WTGXX is structured to behave like a conventional money market fund while operating on blockchain rails. It seeks to preserve a $1.00 net asset value per share. An investment in the fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investors can lose money, and the fund’s adviser is not obligated to reimburse losses or provide financial support during periods of market stress.

The companies’ disclosures also note that blockchain technology remains relatively new, with limited regulation. Potential risks include vulnerability to fraud, theft, or inaccessibility, and future regulatory developments could affect the fund’s viability.

Both firms positioned the partnership as an initial step toward wider use of tokenized cash-management products in regulated markets and stablecoin infrastructure.
