Coinbase is investing in ProShares’ GENIUS Money Market ETF (IQMM), designed to qualify as a stablecoin reserve asset under the GENIUS Act. IQMM holds short-term U.S. Treasuries with maturities of 93 days or less, plus cash and cash equivalents, matching the law’s 1:1 backing standard for high-quality liquid reserves. The move pushes Coinbase deeper into stablecoin plumbing — reserve management, liquidity, issuance, and redemption — as the market moves beyond payments into regulated cash infrastructure.
