Hyperliquid's open interest expanded sharply over the third quarter of 2026, propelling the decentralized derivatives exchange past several of the industry's largest centralized platforms, including Bybit, Kraken and OKX.

According to a report published by the independent research group Hyperliquid Research Collective (HRC), open interest on Hyperliquid climbed to $16.8 billion by the end of September, an increase of nearly 80% from the end of June. The exchange also set a new record during the period, with open interest reaching $18.1 billion on September 22 — the platform's highest level on record.

The growth reflects Hyperliquid's deepening foothold in the crypto derivatives market at a time when a growing number of users are turning to decentralized exchanges to trade derivatives. Unlike centralized venues, decentralized exchanges run trading and settlement on-chain: traders post collateral to smart contracts rather than depositing funds with a company that holds customer assets.

Gaining Ground on Centralized Rivals

Hyperliquid's advance also showed up in its share of total open interest measured across eight leading centralized exchanges. Per HRC's figures, that share rose from 9.6% on June 30 to 11.7% on September 30, suggesting the platform captured a larger portion of the derivatives market over the three-month window.

Centralized venues have historically dominated crypto derivatives trading. With $16.8 billion in open interest at the close of September, Hyperliquid stood ahead of established centralized venues such as Bybit, Kraken and OKX. The milestone marks a significant step forward for decentralized derivatives platforms as they compete for market share against centralized exchanges, and it highlights the platform's success in attracting greater activity and strengthening its position in the broader crypto market.

Open interest refers to the combined value of derivative contracts that have been opened but not yet settled. For exchanges, it is often watched as a measure of engagement, since a rising trend may indicate greater activity on a platform and increased demand for leveraged trading. Higher open interest, however, does not necessarily signal market participants' price expectations, nor does it show whether the market is trending upward or downward.

Expansion Into Prediction Markets

Beyond its core derivatives business, Hyperliquid has drawn attention for the growing range of financial instruments available on the platform. On November 11, The Wall Street Journal reported that Hyperliquid customers had begun placing bets on a company's future valuation ahead of its initial public offering (IPO).

Event-driven markets like these let traders take positions on the outcomes of real-world occurrences rather than on token prices alone. Through such agreements, participants can gain exposure to changes in a company's value without obtaining access to its shares. Rather than granting equity ownership, these arrangements are tied to valuation outcomes. The development illustrates how Hyperliquid is extending beyond traditional cryptocurrency derivatives and attracting interest in markets connected to private companies and other financial events.

The expansion may open the platform to participants seeking different kinds of financial exposure, and it underscores how decentralized platforms are developing innovative methods of delivering market-oriented products beyond Bitcoin and other cryptocurrencies.

Hyperliquid's open interest continued to reach record levels through the third quarter, even as the platform's newer markets attracted attention of their own. How durable the position it has built in the derivatives space proves to be will depend on the growth it sustains going forward. The coming months will show whether the platform can maintain that momentum across both its derivatives business and its newer offerings.
