Perpetual DEX volume reaches $7.9T in 2025 as Onchain trading scale.

Permanent decentralized exchanges are closing in on 2025, reaching a total of $12.09 trillion, up from $4.1 trillion at the beginning of the year.

Of this lifetime total, $7.9 trillion will be generated by 2025, according to Defilama data. This focus shows how fast onchain derivatives will scale in 2025.

In December alone, perpetual trading volume reached $1 trillion, picking up momentum from October, when monthly volume hit $1 trillion for the first time.

The increase reflects a significant acceleration in the use of onchain derivatives over the past 12 months.

Perpetual DEXs began to emerge around 2021, with dYdX and Perpetual Protocol widely considered among the first platforms to offer decentralized perpetual futures onchain.

By 2023, the growth of the sector has increased rapidly, the emergence of hyperliquids has brought about a significant change.

Perp DEX activity accelerated in the second half of 2025

In the year The nearly $8 trillion that was raised in all of 2025 was mostly allocated in the second half of the year.

According to Defilama data, the first half of 2025 will reach $2.1 trillion, while the second half will reach $5.74 trillion, representing 73% of the year's total.

Trading activity remained relatively stable through the first half of 2025, suggesting consistent use of onchain derivatives rather than a phase-out.

This pattern reversed in the middle of the year, with volumes accelerating in the third quarter before reaching an inflection point in Q4, when monthly volumes began to consistently exceed $1 trillion. The fourth quarter transaction volume will exceed the total transaction volume in the first half of 2025.

As liquidity becomes stronger and performance improves, perpetual DEXs are increasingly acting as primary venues for advanced trading rather than additional options for centralized exchanges.

As rival DEXs gain traction, high liquidity dominance is tested

HyperLiquid has dominated the Perps DEX space for most of the year, especially in the first six months, with monthly volume consistently ranging from $175 billion to $248 billion.

Competing platforms, including Aster and Liter, have been comparatively small during that time, with Aster posting single-digit billions and Liter starting to scale after the first quarter.

The competitive landscape began to change midway through the year, with rival platforms accelerating faster than Hyperliquid. Both Aster and Leiter have posted sharp levels in the move since June.

Lender moved from less than $50 billion in monthly volume to more than $100 billion in the third quarter, reflecting its growing merchant adoption and liquidity depth.

The most obvious challenge to HyperLiquid's dominance emerged in the fourth quarter. Aster posted explosive growth in October and November, with monthly volume rising to $259 billion in both months.

By the end of the year, the data pointed to a shift from a single leader market to a competitive, multi-venue ecosystem.
