Coinbase backs $22B ProShares ETF as stablecoin reserve rules take shape

Coinbase invested an undisclosed amount in ProShares' GENIUS Money Market ETF, a $22 billion fund designed to hold reserve assets that comply with the recently enacted stablecoin law.

"The stablecoin industry needs reserve tools built for this market, not repurposed from traditional cash management," a Coinbase spokesperson said.

IQMM, which launched in February, generated $17 billion in trading volume on its first day, according to Bloomberg Intelligence analyst Eric Balchunas. The fund invests exclusively in short-term US Treasury securities with maturities of 93 days or less, along with cash and cash equivalents — the exact asset classes required under Section 4 of the GENIUS Act. The law, passed in June 2025, mandates that payment stablecoin issuers back their tokens one-to-one with high-quality, highly liquid assets.

The investment positions Coinbase at the center of the regulated reserve infrastructure behind dollar-backed stablecoins, a market that will face formal federal rules by early 2027. As stablecoin creation and redemption scales, issuers will need purpose-built reserve products rather than traditional cash-management tools adapted for crypto, Coinbase said.

Coinbase's bet on IQMM extends its stablecoin strategy beyond payments and distribution into reserve management, one of the less visible but critical layers for stablecoin adoption. The exchange already serves as a primary infrastructure provider for Circle's USDC and has built a business around stablecoin payments, custody, trading and institutional services.

The investment comes alongside a separate partnership with payments processor Checkout.com, which will allow more than 1,000 enterprise merchants to accept stablecoins including USDC and Tether's USDT while settling through Checkout.com's existing infrastructure.

CLARITY Act Debate Intensifies

The GENIUS Act gave stablecoins a federal framework, but lawmakers are still debating broader market structure reforms through the Digital Asset Market Clarity Act. The bill, which includes provisions allowing stablecoin issuers to offer yield on token holdings, advanced through the Senate Banking Committee last month.

JPMorgan Chase CEO Jamie Dimon said last week that banks would fight the legislation in its current form, arguing that allowing crypto firms to offer yield on stablecoin balances would create an uneven competitive landscape. White House crypto adviser Patrick Witt said administration officials are targeting the period around the July 4 holiday to advance the legislation, though disagreements persist among Senate Democrats over ethics and conflict-of-interest provisions tied to digital assets.

For Coinbase, the regulatory trajectory matters directly. If the CLARITY Act passes with yield provisions, it would reshape the competitive dynamics between crypto platforms and traditional banks. If it stalls, the stablecoin market will grow under the GENIUS Act's reserve rules alone — a scenario that still favors Coinbase's infrastructure bet on IQMM and similar products.
