Hyperliquid News: Ethereum Overtakes Bitcoin in Open Interest

Bitcoin has led crypto derivatives markets for most of the industry's history. On Hyperliquid, that changed this week, with Ethereum's open interest overtaking Bitcoin's for the first time in this cycle.

The shift is playing out on a platform that has grown fast enough to command nearly a tenth of all global perpetual futures open interest.

Hyperliquid Market Data

Figures reported as of late September 2026:

• ETH open interest on Hyperliquid: approximately $3.02 billion

• BTC open interest on Hyperliquid: approximately $2.80 billion

• Hyperliquid's share of global perpetual futures open interest: 8.7% to 10.9%

• Total open interest on Hyperliquid: approximately $18 billion (a record high for the platform)

• Maximum leverage offered on Hyperliquid: up to 50x

Main News: What the Open Interest Flip Means

Open interest tracks the total value of derivative contracts still open on Hyperliquid, the ones neither side has closed, settled or had liquidated. It is different from trading volume, which measures how much changes hands over a set period.

A higher open interest figure means more capital is sitting in active positions on Hyperliquid. It does not by itself say whether that capital is betting up or down, since every contract has both a long side and a short side.

Hyperliquid News Today: The ETH-BTC Contest in 2026

This is not the first time the two assets have swapped places on Hyperliquid this year. Through 2026, ETH and BTC have gone back and forth for the top open interest spot on the platform, with leadership moving between the two several times.

The current lead for ETH is the latest flip in that ongoing contest. It reflects capital rotating between the two assets on Hyperliquid rather than a one-time event.

Hyperliquid's Growth From Niche to Notable

Hyperliquid launched around 2023 with a straightforward pitch: bring centralized-exchange speed to a fully decentralized platform. Some details on how the exchange is built:

• Blockchain: its own Layer-1

• Trading model: an on-chain central limit order book (CLOB), instead of the automated market maker (AMM) model most decentralized exchanges use

• Maximum leverage: up to 50x across its markets

• Total open interest: approximately $18 billion as of late September 2026, a record for the platform

The CLOB structure is one reason Hyperliquid can offer higher leverage and faster execution than many AMM-based competitors.

The HIP-3 Framework and Tokenized Markets

Hyperliquid expanded beyond crypto assets in October 2025 with the launch of its HIP-3 framework. This opened tokenized markets for:

• Equity indices, including the S&P 500

• Commodities

• Individual stocks

At certain points, some of these tokenized asset markets have overtaken Bitcoin itself in open interest on Hyperliquid. This shows how much the platform's activity now extends past its original crypto-only markets.

Why the Open Interest Flip Matters Beyond Hyperliquid

Concentrated open interest on a single decentralized venue carries platform-specific risk. Some risk factors named in connection with this concentration:

• Smart contract vulnerabilities: an issue in the underlying code could affect a large share of outstanding positions at once

• Oracle failures: since price feeds power the CLOB, a faulty oracle could disrupt trading or liquidations

• Liquidity crises: with open interest concentrated on one venue, a liquidity crunch could move through the system quickly

Hyperliquid's CLOB model is more capital-efficient than AMM-based alternatives. That efficiency also means matching and settlement activity is concentrated on a single venue, an arrangement that is still relatively untested at this scale.
