WisdomTree and MoonPay Partner on WTGXX Access and Stablecoin Reserves

WisdomTree, Inc. (WT ) and MoonPay announced a strategic collaboration on September 17, 2026 to make the WisdomTree Treasury Money Market Digital Fund (WTGXX), a tokenized money market mutual fund, more accessible to everyday investors in the U.S. through MoonPay, according to WisdomTree’s announcement. As part of the initiative, MoonPay plans to use WTGXX as part of its stablecoin reserve management.

Under the collaboration, WisdomTree is building an access point for its tokenized funds that leverages MoonPay’s technology and platform. MoonPay’s blockchain technology is expected to support the planned access point, enabling WisdomTree to reach individual investors directly beyond its own direct channels through its broker-dealer, WisdomTree Securities, Inc., and into MoonPay’s network, which the announcement states hosts over 35 million accounts and serves more than 1,700 partners.

“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. For us, progress means creating more natural, intuitive ways to put capital to work, and making tokenized funds a practical part of an investor’s portfolio management is how we get there.”

“This year, we have seen rapid adoption of blockchain infrastructure and tokenization of financial assets to expand investor access,” said Caroline D. Pham, CEO of MoonPay Institutional. “Our working relationship with WisdomTree demonstrates how financial innovation can enable better experiences for investors in U.S. regulated markets and products.”

WTGXX is distributed by WisdomTree Securities, Inc., a member of FINRA. MoonPay is not acting as a broker-dealer or investment adviser with respect to WTGXX.

WTGXX Fund Design

WTGXX is an open-end Treasury money market fund registered under the Investment Company Act of 1940 whose objective is to provide a high level of current income consistent with capital preservation and liquidity while maintaining a stable net asset value of $1.00 per share, according to the fund’s FAQ document. The fund complies with Rule 2a-7, which permits amortized cost accounting subject to investment and risk limitations that include a weighted average maturity below 60 days, at least 25% of assets in daily liquid instruments, at least 50% of assets in weekly liquid assets, daily shadow NAV calculations, and regular stress testing. WisdomTree states the fund is designed to support reserve-eligibility use cases under the GENIUS Act, investing in a manner intended to satisfy the requirements for eligible reserve assets that payment stablecoin issuers are permitted to maintain under that law, alongside compliance alignment with ERISA and NYDFS frameworks.

The FAQ states the fund held $876 million in assets under management as of April 30, 2026, carries a 0.25% expense ratio, and requires a minimum investment of $1. Income accrues daily and is paid monthly, with dividends available in cash, in stablecoin through WisdomTree’s Stablecoin Conversion Service, or reinvested as additional fund shares. Voya Investment Management serves as sub-adviser, actively managing the portfolio within Rule 2a-7 limits. WTGXX operates natively on Ethereum, Avalanche, Arbitrum, Base, Optimism, Plume, Stellar, and Solana. Prior to November 1, 2025, the fund was known as the WisdomTree Government Money Market Digital Fund.

The fund’s FAQ describes two existing access channels. U.S. retail investors can purchase WTGXX through the WisdomTree Prime mobile app, funding accounts via ACH or direct deposit, while institutions can access the fund through WisdomTree Connect using U.S. dollar wires or USDC and PYUSD processed through the Stablecoin Conversion Service. Since July 2025, the fund has supported withdrawals to whitelisted, self-custodied wallets on all supported blockchains, enabling peer-to-peer movement of fund shares between verified and permissioned addresses subject to KYC/AML and wallet-whitelisting controls. Primary market transactions occur directly with the fund at its daily net asset value, struck at 4:00 p.m. Eastern Time on days the fund is open for business, with T+0 settlement on eligible business days.

Earlier 24/7 Trading Launch

The MoonPay collaboration follows WisdomTree’s February 24, 2026 launch of 24/7 trading and instant settlement for WTGXX, which the firm described as the first time registered tokenized mutual fund shares were permitted to trade and instantly settle 24/7 within the U.S. regulatory perimeter through a dealer-principal liquidity model. That launch followed exemptive relief from the Securities and Exchange Commission obtained by multiple WisdomTree entities, along with a separate FINRA approval allowing WisdomTree Securities to expand its broker-dealer activities to include principal trading of registered fund shares. Trading occurs through bilateral transactions in which WisdomTree Securities acts as principal up to its balance-sheet capacity rather than through an exchange or trading venue, with USDC as the initial settlement stablecoin; the firm said at the time that the functionality would be made available to institutional investors via WisdomTree Connect.

In tandem with the February launch, WisdomTree unveiled continuous dividend accrual, allocating each day’s income based on how long each verified wallet held its tokens and using blockchain timestamps to track intraday transfers. The fund FAQ states the 24/7 secondary market operates on Ethereum and is supported by $10 million of WTGXX inventory on the buy side and $20 million of USDC inventory on the sell side, with instant sales through WisdomTree Connect’s Instant Liquidity service currently facilitated at 0 basis points, while instant purchases may be subject to commissions charged by WisdomTree Securities. Trading continues through weekends and holidays when inventory is available.

WisdomTree and MoonPay said the collaboration is expected to serve as the foundation for a broader strategic engagement between the two companies to support additional tokenized fund opportunities, including across global markets.
