Hyperliquid just pulled off something that most DeFi protocols only daydream about. The perpetual futures exchange negotiated a deal to receive up to 90% of the reserve yield generated by USDC sitting on its platform, with that revenue flowing directly into buybacks of its native HYPE token.

The arrangement, called “Aligned Quote Asset v2” (AQAv2), effectively redirects stablecoin income that would normally stay in Circle’s and Coinbase’s pockets.

How the deal works

When USDC exists, it’s backed by reserves, mostly short-term US Treasuries and cash equivalents. Those reserves generate yield. Historically, Circle and its distribution partner Coinbase have kept that yield as their primary revenue stream.

Under the AQAv2 structure, Hyperliquid captures up to 90% of that reserve income on USDC held within its ecosystem. With roughly $5 billion to $5.5 billion of USDC on the platform, that translates to approximately $135 million to $160 million in annual buyback fuel at current interest rates. If USDC balances grow, estimates suggest that figure could climb to $300 million to $500 million annually.

The mechanics involve both Circle and Coinbase playing distinct roles. Coinbase handles the treasury deployment for USDC, while Circle manages minting and redemptions. Both companies are also staking $20 million as validators on the Hyperliquid network.

All of this yield gets routed through Hyperliquid’s Assistance Fund, which executes the HYPE buybacks. The protocol has also established a $30 million repurchase authorization to formalize the buyback program.

What Circle and Coinbase are giving up

Equity analysts estimate the deal will reduce annual EBITDA for Circle and Coinbase by a combined $60 million to $80 million.

Circle and Coinbase are sharing their yield in exchange for having USDC as the dominant quote asset on one of the fastest-growing trading venues in crypto. By running validators with $20 million commitments each, Circle and Coinbase are also embedding themselves into Hyperliquid’s infrastructure layer.

The buyback machine

For HYPE holders, the token now has a structured, recurring buyback mechanism funded by two separate revenue streams: trading fees from the exchange itself and USDC reserve yield from the AQAv2 deal.

At the estimated $135 million to $160 million annual range, these buybacks represent a meaningful share of HYPE’s circulating market activity. The $30 million repurchase authorization suggests the program is already active, with the Assistance Fund serving as the execution vehicle.

What this means for investors

Stablecoin reserve yield has been the exclusive domain of issuers since USDC launched in 2018. The idea that a sufficiently large platform can negotiate to capture the vast majority of that yield is new territory.

Hyperliquid’s buyback program is directly tied to interest rates. If the Federal Reserve cuts rates aggressively, that $135 million to $160 million estimate shrinks proportionally.

There is also concentration risk in tying a significant portion of a token’s value proposition to a single counterparty deal. Any renegotiation, regulatory challenge to USDC’s reserve structure, or deterioration in the Circle-Hyperliquid relationship could unwind the thesis. USDC balances on Hyperliquid serve as a leading indicator of whether the flywheel is actually spinning.
