Hyperliquid Now Holds 58% More USDC Than Coinbase's Own Chain, and Most of Its Yield Goes to Hyperliquid.
Five months after Coinbase and Circle agreed to hand Hyperliquid most of the yield on its USDC, the trading venue's chain holds US$6.93 billion of it. Base, the chain Coinbase built, holds US$4.38 billion. More of Circle's dollar now sits where the venue, not Circle and Coinbase, takes most of the yield.
- At the October 4 close, Hyperliquid's chain held US$6.93 billion of USDC and Coinbase's Base held US$4.38 billion: 1.58 times as much, a lead of US$2.55 billion.
- Hyperliquid has held more USDC than Base on all 52 daily readings since August 13. Its USDC rose US$1.34 billion over that span; Base's rose US$0.13 billion.
- Under the May 2026 deal that made Coinbase Hyperliquid's USDC treasury deployer, Hyperliquid receives about 90% of the reserve income on that USDC, so more USDC now sits where the venue takes most of the yield than on Coinbase's own chain.
Hyperliquid's chain held US$6.93 billion of USDC at the October 4 close. Base, the chain Coinbase built to host everything onchain, held US$4.38 billion. The chain built around a single derivatives exchange now holds 1.58 times as much of Circle's dollar as Coinbase's own network, a lead of US$2.55 billion.
The size of the gap matters because of a deal struck in May. Coinbase became Hyperliquid's official treasury deployer for USDC, and under the terms Hyperliquid receives about 90% of the reserve income on the USDC its users hold. Interest on the reserves behind each USDC is how Circle and Coinbase earn on the dollar. On Base, that income stays with Circle and Coinbase. On Hyperliquid, most of it goes to the venue. The pool where the venue takes most of the yield is now the bigger one.
Third among USDC's chains, behind only Ethereum and Solana

After Ethereum and Solana, the next-largest USDC chain is built around one exchange.
USDC supply at the October 4 close, in US dollars, for USDC's second-, third- and fourth-largest chains. Solana holds US$8.33 billion, Hyperliquid (green) US$6.93 billion and Base (blue) US$4.38 billion. Ethereum, the largest by far, is not shown.
Hyperliquid is not closing in on Solana. Solana held US$8.33 billion on October 4 and stayed ahead on every day we read. Hyperliquid's rank is third, and it has held third on all 52 days. The comparison that has never wavered is the one with Base: Hyperliquid's smallest lead was US$1.34 billion, on August 13, the first day we read its chain.

Hyperliquid added US$1.34 billion of USDC while Base added US$0.13 billion.
Daily USDC supply on Hyperliquid (green), Base (blue) and Solana (grey), in US dollars, August 13 to October 4. Hyperliquid rose from US$5.59 billion to US$6.93 billion, most of it by September 22, and has held between US$6.87 billion and US$7.07 billion since September 21. Base moved from US$4.25 billion to US$4.38 billion. There is no reading for September 30.
Since August 13, Hyperliquid's USDC grew 24.0 percent. Base's grew 2.9 percent. The growth on Hyperliquid came in a run through late September and has since leveled off: from September 21 to October 4 it stayed between US$6.87 billion and US$7.07 billion. Base spent the same weeks between US$4.27 billion and US$4.38 billion. Neither chain is shrinking. One is where the new dollars went.
Why it matters: the terms travel
For a stablecoin issuer, distribution has usually meant getting the dollar onto as many chains as possible and keeping the interest. The Hyperliquid deal is a different shape: the venue that gathers the deposits takes most of the income. Analysts warned in May that other protocols may now demand similar terms. That warning carries more weight when the venue holding the shared pool is larger than the issuer's own chain. Any venue that gathers billions of a stablecoin now has a public precedent for asking for the yield.
For anyone tracking where dollar exposure sits, the map has an exchange on it. Hyperliquid's measured holdings are almost entirely USDC, so the venue's dollar base and Circle's distribution are tied together. The USDC on Hyperliquid is collateral on a venue built for leveraged trading, held under that venue's rules and economics. The open question is whether the next billions follow the trading to whichever venue offers depositors the most, or whether Base and the general-purpose chains win them back. Hyperliquid's flat line since late September is the first thing to watch: renewed growth would say the deal is still pulling dollars in; a plateau would say it has found its level.
At the October 4 close, USDC on Hyperliquid was US$6.93 billion and on Base US$4.38 billion, a lead of US$2.55 billion (1.58 times). Hyperliquid led Base on all 52 daily readings from August 13 to October 4; its smallest lead was US$1.34 billion.
OnChain Benchmark per-chain totalSupply readsFrom August 13 to October 4, Hyperliquid's USDC rose US$1.34 billion (24.0%) and Base's US$0.13 billion (2.9%). Since September 21, Hyperliquid has held between US$6.87 billion and US$7.07 billion. There is no reading for September 30.
OnChain Benchmark per-chain totalSupply readsHyperliquid's figure is Circle-native USDC on its HyperEVM chain. A further US$394.15 million sat in Hyperliquid's bridge contract on Arbitrum at the same close; it is counted under Arbitrum, not Hyperliquid, so Hyperliquid's full USDC footprint is larger than shown. The US$74.53 billion total covers the 20 chains we publish; it is not all USDC.
OnChain Benchmark reads, Arbitrum block 511,747,772- How much USDC is on Hyperliquid?
- US$6.93 billion of Circle-native USDC on Hyperliquid's HyperEVM chain at the October 4, 2026 close, 9.30% of the US$74.53 billion OnChain Benchmark publishes across 20 chains. A further US$394.15 million sat in Hyperliquid's bridge contract on Arbitrum.
- Is there more USDC on Hyperliquid than on Base?
- Yes. At the October 4, 2026 close Hyperliquid held US$6.93 billion and Base US$4.38 billion. Hyperliquid has led Base on every daily reading since August 13, by at least US$1.34 billion.
- Who earns the interest on USDC held on Hyperliquid?
- Under the arrangement announced in May 2026, Coinbase is Hyperliquid's official USDC treasury deployer and Hyperliquid receives about 90% of the reserve income on that USDC, as reported by CoinDesk.
