HEADLINE
ProShares Stablecoin ETF Hits $17B Day One

Source: Eric Balchunas
State of play: ProShares’ GENIUS Money Market ETF, IQMM, recorded a record $17B in first day trading volume. The fund holds assets that meet US stablecoin reserve requirements under the GENIUS Act, including highly liquid US Treasury bills.
The launch far surpassed previous ETF debuts, including BlackRock’s IBIT at $1B on day one.
Analysts suggest institutional capital allocation strategies may have driven flows, potentially involving a major US stablecoin issuer.
The debut highlights deeper integration between stablecoin infrastructure and traditional money market products as stablecoins approach $300B in supply.
What’s Next: If flows remain stable, expect more stablecoin aligned ETFs and reserve focused products to launch under the GENIUS framework.
Why it Matters: This tightens the link between stablecoins and US Treasuries. It effectively brings stablecoin reserve mechanics into public markets and institutional portfolios.
Our Take: If major players are anchoring flows, stablecoin infrastructure is quietly becoming part of mainstream liquidity management.
