Key takeaways
- ProShares stablecoin-ready money market ETF holds $17.8 billion
- Treasury income benefits issuers, fund managers and investors
- Large stablecoin redemptions could threaten ETF liquidity
ProShares' $17.8 billion money market ETF is revealing how Wall Street could profit from the growing demand for dollar-backed stablecoins, turning cryptocurrency reserves into a lucrative market for traditional asset managers.
The ProShares GENIUS Money Market ETF, trading under IQMM, held approximately $17.81 billion in assets as of early November. Its seven-day SEC yield stood at 3.84% on November 2, with a net expense ratio of 0.15%.
Launched in February 2026, the fund targets institutions managing stablecoin reserves under the GENIUS Act, highlighting an emerging competition over the Treasury income generated by digital dollars.
How ProShares Turned Stablecoin Reserves Into an ETF Business
IQMM invests exclusively in cash and short-term US Treasury securities, with individual investments limited to maturities of 93 days or less.
That structure aligns with reserve requirements under the GENIUS Act, allowing qualifying stablecoin issuers to hold the ETF as part of their backing assets.
Unlike traditional money market funds, IQMM trades on an exchange, calculates its net asset value twice daily and offers same-day settlement.
These features are particularly attractive to companies managing billions of dollars in redeemable tokens.
ProShares reported 100% daily and weekly liquid assets on November 2, alongside a weighted average maturity of approximately 45 days.
Its 0.15% annual net expense ratio creates a recurring management-fee opportunity. Applied illustratively to $17.81 billion in assets, that rate would equal roughly $26.7 million annually, before changes in assets or fees.
The opportunity is attracting competitors. Franklin Templeton has modified institutional funds for regulated stablecoin reserves, while BlackRock previously restructured a Treasury liquidity fund targeting the same market.
Who Actually Profits From the Treasury Trade?
The economics begin when customers exchange dollars for stablecoins.
Issuers invest qualifying reserve assets in interest-generating instruments, while holders generally receive tokens designed to maintain a $1 value.
The resulting reserve income supports stablecoin issuers, while asset managers collect investment-management fees.
Circle illustrates the scale of the business. Its reserve income reached $667.7 million in the second quarter of 2026, representing more than 95% of revenue.
However, revenue does not equal profit. Distribution partners, custody providers and operating expenses also absorb substantial amounts.
The Hidden Risk in Stablecoin-Focused Money Market ETFs
ProShares acknowledges that stablecoin issuers may become the fund's largest shareholders, creating concentrated redemption risks.
If investors rapidly redeem stablecoins, issuers could sell significant ETF positions to raise cash.
That pressure could affect IQMM's liquidity, yield and share price, even though its underlying holdings are short-term government securities.
The fund also does not promise a fixed $100 share price or provide FDIC deposit insurance.
As stablecoin adoption expands, the opportunity extends beyond token issuers to asset managers, custodians and financial intermediaries.
