WisdomTree, MoonPay Plan US Access Route for $1.2B WTGXX Fund
WisdomTree and MoonPay used a Sept. 17 announcement to describe a planned US access point for the WTGXX tokenized Treasury money market fund, while MoonPay said it intends to put the fund into its stablecoin reserve stack. Crypto.news reported that eligible US investors would be routed into the regulated fund through WisdomTree’s broker-dealer network rather than through a MoonPay brokerage.
Coverage by Cointelegraph placed the fund at roughly $1.2 billion, with WTGXX accounting for about $1.23 billion of a tokenized US Treasury market worth about $15.4 billion as of Thursday, according to RWA.xyz data. Cointelegraph also reported $466 million of net inflows to the fund over the prior 30 days, citing the same data source.

Key facts
- WisdomTree said the access point will rely on MoonPay’s blockchain technology and distribution network, which the companies say reaches more than 35 million accounts and over 1,700 partner businesses.
- MoonPay has not named the stablecoin that would hold WTGXX reserves, disclosed an allocation amount, or given a date for investor access.
- WTGXX is an open-end money market mutual fund registered under the Investment Company Act of 1940 with a $1.00 target net asset value per share and a 0.25% annual expense ratio.
- At June 30, the fund held 80.9% of net assets in US government obligations and 19.3% in repurchase agreements, per Crypto.news — including overnight repos with institutions such as Deutsche Bank.
- Cointelegraph reported that WisdomTree manages about $176.7 billion in assets, and that the collaboration could extend to other tokenized funds outside the US.
Regulated distribution stays with WisdomTree Securities
WisdomTree states that MoonPay is not a broker-dealer or investment adviser for WTGXX. Securities transactions continue to run through WisdomTree Securities, Inc., the distributor of the fund. The announcement uses present-tense language such as “is building” for the access point and “expected to support” for the technology, which does not confirm that retail investors can buy WTGXX through MoonPay today.
WisdomTree founder and CEO Jonathan Steinberg framed the tie-up as a distribution question rather than a product launch, saying that working with MoonPay as an access point can give eligible US investors another path to deploy assets into WTGXX.

Where WTGXX sits among tokenized Treasurys
The fund was purpose-built for reserve eligibility. WisdomTree changed the product’s name and investment policy in November 2025 so it could serve as an eligible investment option for payment stablecoin issuers working under the GENIUS Act. The current SEC-filed prospectus requires at least 99.5% of total assets in government securities, cash and fully collateralized repurchase agreements, and describes investments intended to satisfy eligible reserve asset categories for payment stablecoin issuers.
Figures in the latest prospectus show the composition as of June 30: Treasury bills made up 64.1% of the portfolio, a floating-rate Treasury note 16.8%, and the fund returned 3.75% for its fiscal year through that date, against 3.90% for the ICE U.S. 1-Month Treasury Bill Index. Past performance does not establish what future investors will earn.
WisdomTree had already widened liquidity before the MoonPay arrangement. In February it introduced 24/7 secondary trading and instant settlement after obtaining SEC exemptive relief, with WisdomTree Securities acting as principal and eligible trades settling against USDC outside standard market hours. By June, secondary-market redemption commissions on the Instant Liquidity service had been cut to zero basis points through WisdomTree Connect.
The fund has appeared in other 2026 treasury and blockchain workflows: Plume and Toku ran a payroll pilot, LotusUSD referenced it in a reserve framework, and Stable Sea made it available for corporate treasury use, expanding in August to two more digital funds alongside WTGXX. The SEC itself lists WTGXX among tokenized money market funds, in an April statistics release that also named products from Franklin Templeton, Fidelity, Dreyfus and M3Sixty.
Why it matters
The tie-up gives a stablecoin issuer and infrastructure provider a funded example of using a registered money market fund for reserves, which is the structure the GENIUS Act points issuers toward. It also tests whether stablecoin distribution networks can widen the investor base of a fund without moving the securities activity out of a regulated broker-dealer. For WisdomTree, the arrangement is a second front beyond direct distribution; for MoonPay, it follows a June link between Franklin Templeton’s BENJI fund and MoonPay Trade for institutions, where eligible institutions could exchange stablecoins such as USDC and USDT for tokenized fund shares. MoonPay Trade launched in May for tokenized assets, stablecoin liquidity and DeFi connections.
What to watch
The named next steps are missing from the announcement: MoonPay has not identified the stablecoin that would hold WTGXX reserves, the allocation size, or a start date for reserve purchases, and neither company has named an additional fund, country or launch schedule for any expansion. Watch for those disclosures. This article is not financial advice, and the tokenized fund and stablecoin markets are volatile and uncertain.
