Polymarket Captures 97% of On-Chain Prediction-Market Fees

The Signal

Polymarket now accounts for 96.8% of all fees generated across on-chain prediction-market platforms, according to DeFiLlama data cited by CoinMarketCap.

The fee share followed Polymarket’s March 30 pricing update, after which daily fees climbed to roughly $1 million and have stayed near that level. The platform generated about $7.1 million in fees during the first seven days of Q2, implying a roughly $365 million annualized run rate if sustained.

Polymarket is now being compared on fee production not just with prediction-market peers, but with major DeFi protocols: CoinMarketCap says the platform ranks eighth across DeFi by fees, near stablecoin issuers and decentralized derivatives venues.

The Mechanism

• Polymarket has turned pricing into a revenue reset. The March 30 fee change did not just lift take rate; it converted elevated event demand into protocol-level cash flow. A $1 million daily fee base gives Polymarket a very different investor story than the old “high-volume, low-monetization” version of the company.

• The 97% figure is on-chain dominance, not total industry dominance. DeFiLlama captures on-chain prediction-market fees, so CFTC-regulated off-chain venues such as Kalshi, Novig, and DraftKings’ Predictions product sit outside the clean comparison. Polymarket is winning the crypto-native fee pool; the regulated U.S. fee pool is still being contested.

• ICE’s investment now looks tied to data economics as much as exchange access. Intercontinental Exchange completed a $600 million cash investment in Polymarket on March 27 as part of a broader $2 billion commitment, with ICE distributing Polymarket’s event-driven data to institutional clients, according to CoinMarketCap. Fee scale gives that data product a stronger liquidity signal.

• TVL is nearing election-cycle highs without a U.S. presidential election driving the tape. Polymarket’s total value locked stood above $432 million on Tuesday, close to the roughly $510 million peak recorded during the November 2024 U.S. election period. The mix has shifted toward global conflict, oil, inflation, equity-index, sports, and crypto markets.

• Referral distribution is becoming a visible growth channel. Multiple affiliate-style placements are pushing Polymarket invite codes, fee rebates, and waitlist access, including offers covered by Golfweek, OregonLive, and Chiefs Wire. That is a sportsbook-style acquisition play layered on top of an exchange-style product.

• The fee lead raises the regulatory stakes. A platform generating hundreds of millions in annualized fees becomes harder for regulators and competitors to treat as a niche crypto app. It also gives state gaming regulators and CFTC critics a larger target as sports-adjacent markets expand.

The Landscape

Market Position

Polymarket is the clear fee leader among on-chain prediction markets, with 96.8% share and daily fee production near $1 million after the March 30 pricing update. Its TVL above $432 million puts the platform within striking distance of its November 2024 election-period peak, but the current demand base is broader: macro, commodities, geopolitics, sports, crypto, and equity-index contracts are all contributing.

The competitive split is now cleaner. Polymarket dominates crypto-native liquidity and on-chain fee capture. Kalshi, Novig, and DraftKings are fighting over federally regulated U.S. distribution, state preemption, and sports-market consumer acquisition. DraftKings’ recently disclosed $11 billion annualized July trading volume shows how fast sportsbook-native demand can scale, but Polymarket is currently the platform converting prediction-market attention into the most visible fee line.

Regulatory Environment

The CFTC’s latest warning to prediction markets not to display American-style gambling odds lands directly in the middle of this monetization push. Bloomberg reported that the agency told licensed prediction-market firms to avoid betting-style odds displays as it defends the sector against claims that event-contract venues are operating like sportsbooks; Sports Business Journal and Northeast Times carried the same warning.

State litigation is still moving in parallel. Kalshi is asking a federal judge to block Iowa from regulating its exchange, according to Courthouse News, while a federal judge in Utah ruled Kalshi is not immune from the state’s gambling ban, per KUER. Novig’s New York lawsuit added another front last week. Polymarket’s fee surge gives the category more capital, but it also gives regulators more evidence that event contracts have become a major consumer-finance business.

Key Data

• 96.8%: Polymarket’s share of fees across on-chain prediction-market platforms, per DeFiLlama data cited by CoinMarketCap.

• ~$1 million per day: Polymarket’s daily fee level after its March 30 pricing update.

• $7.1 million: Polymarket fees generated during the first seven days of Q2.

• ~$365 million: Implied annualized fee run rate if the early-Q2 pace holds.

• $432 million+: Polymarket TVL as of Tuesday, versus an approximate $510 million peak during the November 2024 U.S. election period.

What’s Next

The next industry catalyst is whether Polymarket can maintain the post-pricing fee run rate as regulated U.S. competitors move deeper into sports and consumer acquisition. Watch three signals: DeFiLlama fee share, TVL versus the $510 million election-cycle peak, and any CFTC or state response to platform UX that resembles sportsbook distribution. If Polymarket keeps $1 million daily fees while DraftKings, Kalshi, and Novig fight in court and in app-store funnels, the category’s center of gravity shifts from “can prediction markets attract volume?” to “who is allowed to monetize it at scale?”
