Arbitrum has climbed to the No. 2 spot among major perpetual futures markets, recording $1.48 billion in 24-hour volume and $1.834 billion in open interest.
ARB$0.076952+3.40%Arbitrum has emerged as one of the biggest venues for cryptocurrency perpetual futures, climbing to the No. 2 spot among major perps markets on August 18 after recording roughly $1.48 billion in 24-hour trading volume.
The data, shared by BSC News, also showed $1.834 billion in open interest on Arbitrum, while its seven-day perpetual volume reached approximately $6.70 billion. Hyperliquid remained well ahead of the competition with about $6.12 billion in 24-hour volume.
The numbers highlight the growing importance of Arbitrum as a venue for leveraged crypto trading and add to the network's broader push toward becoming a major infrastructure layer for on-chain financial markets.
Perpetual futures are derivatives that allow traders to take leveraged long or short positions without a traditional expiration date. They have become one of the largest sources of trading activity across crypto markets.
Arbitrum's rise in perps activity is particularly notable because the volume comes from multiple protocols operating across the network rather than a single exchange.
DeFiLlama's Arbitrum derivatives dashboard tracks perpetual activity from protocols including Variational, Ostium, GMX, Boros, Hibachi and Gains Network, among others.
This creates a broader derivatives ecosystem where traders can access different approaches to perpetual trading while using Arbitrum as the underlying network.
The latest snapshot also shows that Arbitrum's derivatives activity remains substantial beyond the single-day figure. DeFiLlama's current data continues to record more than $1 billion in daily Arbitrum perp volume, illustrating that the network has developed a meaningful derivatives market rather than relying on a one-off volume spike.
Despite Arbitrum's rise to second place, Hyperliquid remains the dominant market in the figures shared on August 18.
Hyperliquid recorded approximately $6.12 billion in 24-hour perpetual volume, putting it several times ahead of Arbitrum's $1.48 billion.
The gap demonstrates how competitive the on-chain derivatives sector has become.
Hyperliquid has built its ecosystem around high-performance trading infrastructure, including an on-chain central limit order book for perpetual and spot markets. A CFTC filing describing the platform identifies HyperCore as the execution layer supporting its perpetual futures and spot trading.
Arbitrum, by comparison, has taken a more ecosystem-driven approach, with multiple derivatives protocols operating across its network.
The $1.834 billion in open interest reported for Arbitrum provides another important part of the picture.
Trading volume measures how much notional value changes hands, while open interest represents the value of outstanding derivatives positions.
A high open-interest figure alongside substantial trading volume indicates that the market is supporting a significant amount of active leveraged exposure.
However, open interest should not automatically be interpreted as bullish or bearish.
A trader opening a leveraged long position and another opening a short position can both contribute to open interest. The metric therefore indicates market participation and outstanding positions rather than direction.
For Arbitrum, the combination of high volume and open interest suggests that its perps infrastructure is attracting active derivatives traders.
The growth of perpetual futures fits into a larger strategy for the Arbitrum ecosystem.
The Arbitrum Foundation has increasingly positioned the network as infrastructure for a broader programmable economy, rather than simply an Ethereum scaling network. In June, Arbitrum said its ecosystem had more than 30 dedicated blockchains and nearly $17 billion in total value secured.
The ecosystem has also expanded into financial applications beyond conventional crypto trading.
One example is Ondo Perps, which has been using Arbitrum infrastructure for perpetual markets involving tokenized real-world assets. Arbitrum highlighted Ondo Perps as one of the fastest-growing RWA perpetual platforms, with billions of dollars in cumulative volume.
That development could become increasingly important if tokenized stocks, commodities and other real-world assets continue moving on-chain.
Perpetual futures can be particularly valuable for blockchain ecosystems because derivatives generate frequent transactions and significant liquidity demand.
For Arbitrum, stronger perps activity can potentially reinforce several parts of its ecosystem, including higher on-chain trading activity, greater demand for stablecoin liquidity, increased interaction with DeFi applications, growth in derivatives infrastructure, and further expansion into tokenized real-world assets. The presence of multiple major perpetual protocols also reduces the network’s reliance on a single application.
The presence of multiple major perp protocols also reduces reliance on a single application.
GMX, for example, remains one of the established derivatives protocols on Arbitrum, while newer platforms such as Variational and Ostium contribute additional trading activity. DeFiLlama's data shows the combined Arbitrum perp market is spread across several protocols.
Arbitrum's rise comes as competition among on-chain derivatives platforms intensifies.
Hyperliquid continues to dominate overall perp activity, while other chains and dedicated trading networks are also attracting significant volumes.
The broader DeFiLlama derivatives rankings show how large the sector has become, with tens of billions of dollars in daily perpetual volume across tracked platforms.
This means Arbitrum's second-place position should be viewed as part of a rapidly changing market rather than a permanent ranking.
Its ability to retain that position will depend on whether trading activity remains distributed across its ecosystem and whether newer derivatives products continue attracting liquidity.
The immediate question is whether the August 18 volume represents the beginning of a sustained trend.
Arbitrum already has an established derivatives infrastructure, and recent developments around tokenized assets could provide another source of growth.
The network will need to compete not only on trading volume but also on liquidity, execution quality, available markets and trader incentives.
For now, however, the numbers are significant.
With roughly $1.48 billion in 24-hour perps volume, $1.834 billion in open interest and $6.70 billion in seven-day volume, Arbitrum has established itself as a major destination for on-chain perpetual trading.
Hyperliquid remains the market leader, but Arbitrum's rise to No. 2 shows that the battle for dominance in decentralized derivatives is becoming increasingly competitive.
