Coinbase has put money into ProShares' IQMM ETF, a $22.7 billion fund built around Treasuries. The move ties directly to the GENIUS Act, the stablecoin regulation that's rewriting how crypto firms manage their reserves.
Why Treasuries matter for stablecoins
The IQMM ETF holds short-term U.S. government debt — exactly the kind of asset regulators want backing stablecoins. Under the GENIUS Act, issuers must keep reserves in low-risk, liquid instruments. Treasuries fit that bill. By investing in a Treasury-heavy fund, Coinbase is positioning itself ahead of the new rules, which are still making their way through Congress.
What the $22.7 billion fund tells us
ProShares' IQMM is one of the larger Treasury-focused ETFs on the market. Coinbase's stake, while undisclosed in size, signals that the exchange sees stablecoin regulation as a real near-term shift. The fund's structure gives Coinbase exposure to a diversified pool of government bonds without having to buy them directly — a cheaper, more flexible way to meet reserve requirements if the GENIUS Act passes in its current form.
Stablecoin regulation's ripple effects
The GENIUS Act isn't law yet, but it's already changing behavior. Lawmakers and regulators want stablecoin reserves to be transparent and safe. Coinbase's investment in IQMM suggests the company is betting that Treasury-backed funds will become the standard. That could pressure other exchanges and stablecoin issuers to follow suit, especially if the act forces them to hold more government debt than they do now.
The move also deepens Coinbase's ties to traditional finance. ProShares is known for its ETF lineup, and linking up with a major issuer gives Coinbase a foothold in the $4 trillion Treasury market. For now, the company hasn't said how much it put into the fund or whether it plans to increase the stake. Those details may come as the GENIUS Act moves closer to a vote.
