Hyperliquid open interest hits $14.7 billion, claims 76% share of perp DEX market

Open interest (OI) on Hyperliquid, a decentralized perpetuals exchange, has surged to $14.669 billion, reaching levels not observed in almost eleven months. According to DefiLlama data, OI crossed the $14 billion threshold on September 4 and has continued to climb steadily. Steady growth since February Hyperliquid’s open interest bottomed at approximately $4.76 billion in February 2026. Over the past seven months, OI has grown by about 210%. The increase has been gradual, with no single surge period, setting it apart from the rapid leverage build-up that occurred in October last year. Charts confirm this steady climb began in March, marking a shift toward sustained market participation rather than sudden influxes of capital. Recent catalysts: Coinbase partnership, CFTC talks, token unlock Several developments in recent weeks have contributed to Hyperliquid’s momentum. On August 19, Coinbase announced that its Base app would start routing transactions through Hyperliquid-powered perpetual futures, giving users access to more than 290 perpetual markets, including those in crypto, commodities, and equities. This move opened Hyperliquid to a broader audience and deepened its market presence. Coinbase introduced Hyperliquid’s perpetual futures to its Base app, allowing users to access hundreds of perp markets across various asset classes in a single interface. A day later, US President Donald Trump brought regulatory attention to Hyperliquid by stating that the Commodity Futures Trading Commission (CFTC) was actively working to bring the platform onshore. On September 6, an unlock event released 9.92 million HYPE tokens, valued at around $820 million. Despite concerns that such a significant unlock could affect market stability, open interest reached a new local high the following day, reflecting strong trader confidence. Shift from HIP-3 to core perpetuals markets The composition of open interest within Hyperliquid has shifted over the past month. Earlier in the year, builder-deployed HIP-3 markets were responsible for much of the growth, rising from 18% of OI to over 34% and surpassing $4 billion by August. However, recent data indicates that HIP-3 open interest has declined by approximately $200 million in the last month, while total OI increased by $3.8 billion. Currently, growth is driven mainly by Hyperliquid’s core perpetuals markets. These core markets contribute about 99% of fees to HYPE token buybacks, while builder markets allow deployers to retain up to half of their generated fees. This shift means that recent expansion benefits the HYPE token more directly. Mini dictionary: HIP-3 refers to builder-deployed markets on the Hyperliquid platform, allowing third-party developers to launch new trading pairs directly. These markets differ from core perpetuals, which are operated and curated by Hyperliquid itself. Market share dominance and sector comparison Recent data from Artemis, as of September 8, shows that total open interest across tracked perpetuals DEXs stands at $19.2 billion, with Hyperliquid accounting for $14.6 billion.
