Ethereum overtakes Bitcoin in open interest on Hyperliquid

For most of crypto's history, Bitcoin has been the undisputed king of derivatives markets. On Hyperliquid, that hierarchy just flipped.

Ethereum's open interest on the decentralized perpetual futures exchange has surpassed Bitcoin's, with ETH reaching approximately $3.02 billion compared to BTC's roughly $2.80 billion. On a platform that now accounts for an estimated 8.7% to 10.9% of global perpetual futures open interest, that gap is more than a rounding error.

Open interest measures the total value of outstanding derivative contracts that haven't been settled. It's not volume, which tracks how much changes hands in a given period. OI is more like a headcount of how many traders are still sitting at the table with live bets.

Throughout 2026, ETH and BTC have been locked in a tight contest for the top OI spot on Hyperliquid, with leadership seesawing between the two assets. The current ETH lead suggests a rotation in trader sentiment that's worth watching, particularly because it's happening on a venue that's increasingly representative of broader market positioning.

Hyperliquid launched around 2023 with a simple pitch: deliver centralized-exchange speed and features on a fully decentralized platform. Built on its own Layer-1 blockchain, the exchange runs an on-chain central limit order book, or CLOB, rather than the automated market maker model that most DEXs rely on. That architecture lets it offer up to 50x leverage across its markets.
