Perp DEX fee wars: who is actually earning the volume

Nine venues are competing for the same pool of perpetual futures volume by cutting fees. We traced the fees onchain to find out who keeps the revenue, who is buying volume with tokens, and how long each can afford to keep going.

01 — SUMMARY

Perpetual futures are the largest revenue line in DeFi and the most contested. Since March, average taker fees across the nine venues we track have fallen 71%, with three venues now charging nothing on the maker side and rebating on the taker side.

Only two venues generate more in fees than they pay out in incentives. The rest are buying volume with their own token, at an implied cost of $0.40 to $2.10 per $1,000 traded. At current emission schedules, four of them exhaust their incentive budgets before Q2 2027.

Volume is not the metric. Retained fee per dollar traded is, and on that measure the market has two winners and seven venues renting market share.

02 — WHERE THE VOLUME IS

Reported volume overstates the picture. We removed self-matched trades, wash patterns tied to points programs, and venues that report notional on both legs. Adjusted volume is 38% lower than headline numbers across the group.

03 — WHAT EACH VENUE KEEPS

Gross fees are the wrong number. We net out maker rebates, referral payouts and token incentives paid to traders to get to retained fee per $1,000 of adjusted volume.

Table 1 — Retained fee per $1,000 adjusted volume, 30d. Incentives valued at 30d TWAP. Placeholder values.

A venue paying $2 to earn $0.05 is not competing on fees. It is distributing its token through a trading interface.

04 — PAYING FOR FLOW

Incentive programs at the seven loss-making venues share a structure: points accrue to volume, points convert to tokens at a later date, and the conversion rate is set after the volume has been delivered. This lets a venue defer the cost and report fee revenue as if it were unencumbered.

We value the liability at the 30-day TWAP of the token and the disclosed or inferred conversion rate.1 Where the rate is undisclosed we use the prior epoch. On this basis, Venue D has an outstanding incentive liability equal to 14 months of gross fees.

05 — RUNWAY

Dividing each venue's remaining incentive allocation by its current monthly spend gives the runway below. Four venues run out before Q2 2027 without a new allocation or a token price recovery.

06 — CONCLUSION

The fee war is real but the casualties are predetermined. Two venues can sustain zero-fee pricing indefinitely because their retained fee is positive at any price. The others are paying for market share they cannot hold once payments stop.

We expect consolidation to two or three venues by end of 2027, with the remainder either pivoting to niche products or winding down incentive programs and losing the volume that came with them.
