Hyperliquid Open Interest Hits Record $18B

Hyperliquid open interest reached a record $18 billion on 23 September 2026, according to official platform data cited by Lookonchain. It rose from the previous record of $16.36 billion set four days earlier and was nearly $5 billion above the end-August level. The increase highlights stronger crypto derivatives participation and growing demand for leveraged exposure. Bitcoin, Ether and HYPE accounted for about $9.33 billion of Hyperliquid open interest. Bitcoin led with $4.05 billion, followed by Ether at $3.18 billion and HYPE at $2.10 billion. Zcash and Solana held approximately $858.6 million and $763.7 million, respectively. The record may support market expectations for HYPE to reach the widely discussed $100 year-end target, although open interest alone does not establish a bullish price direction. Hyperliquid is also expanding beyond cryptocurrencies through its HIP 3 framework, which supports perpetual markets linked to equities, commodities, indices and private companies. S&P 500-linked contracts had about $418.9 million in open interest, while gold had roughly $301.7 million. HIP 3 markets represented around 30% of platform trading volume over the previous 30 days, with cumulative volume exceeding $548 billion by early September. For traders, the rise in Hyperliquid open interest signals deeper liquidity and greater derivatives activity, but it also increases liquidation and short-term volatility risks. Open interest measures outstanding long and short positions, not net buying. Traders should monitor funding rates, volume, liquidations, institutional participation, partnerships, security developments and regulatory news. Hyperliquid is also adding event contracts, lending products, trailing stops and planned permissioned US markets.
