Quick Take

Summary is AI generated, newsroom reviewed.

  • Perp DEXs hit $1.143 trillion in September trading volume, a first in DeFi history.

  • Growth surged nearly 50% month-on-month, per DeFiLlama data.

  • Hyperliquid, Aster, and Lighter each crossed $100B in 30-day volume.

  • Regulatory pressure and security risks remain key challenges.

The decentralized finance (DeFi) derivatives market has already reached a historic high, as perpetual decentralized exchanges (Perp DEXs) are trading more than $1.143 trillion in September 2025, according to new data on DeFiLlama. It is the first time in history that Perp DEX activity every month has topped the trillion-dollar mark, a nearly 50 percent increase over the estimated August figure of 762 billion.

Protocol Leaders in the Trillion-Dollar Surge

The boom is symptomatic of a rapidly increasing transition between the centralized exchanges and the decentralized platforms. The numbers recorded in September equate to a daily average of approximately 38 billion in trades which are comparable to the scope of stock markets across the world. Analysts observe that protocols generated about 1.143 billion revenues at a normal rate of 0.1% last month, which underscores the economic importance of this new industry.

The largest players included Hyperliquid, Aster and Lighter, all of which had more than $100 billion of trading within the last 30 days. Hyperliquid remains at the forefront with fierce liquidity incentives and profound markets. Aster is a fairly new player that is making rapid gains and taking up market share. In the meantime, Lighter, supported by Amber Group and still in beta as of early 2025 has already added over 161 billion of cumulative volume. Collectively these protocols can amount to close to half of the trillion dollar turnover in September.

What’s Fueling the Growth

The larger pattern is that decentralized derivatives have broken out in 2025. An annual volume of Perp DEX amounted to an estimated 500-700billion in 2024 whereas in this year the September volume was in the trillion category. Early parts of October indicate that trading is already topping over 120 billion, which is a precursor to a possible 1.5 trillions at the year end. Blends of Ethereum Layer-2 rollups reducing transaction fees, incentive schemes such as token buybacks and fresh market zeal amidst crypto price spikes have provided the ideal atmosphere to this boom.

Still, challenges remain. An increase in regulatory scrutiny, particularly in areas such as China where virtual currency trading is still heavily banned, is increasing. The security factor is also a major concern since the increasing liquidity pools are the favorite targets of exploits. The major DEXs may go into a fee war with each other, which may affect profitability.

Regardless of these dangers, the September numbers represent a turning point. Perp DEXs now play a central role in the global crypto trading ecosystem with a volume worth $1.143 trillion monthly. It is possible that in the near future, decentralized perpetual futures will become the leading competitors to centralized exchanges regarding their liquidity and influence.
