Five Web3 Prediction-Market Projects Show Different Models in 2026

Coinbase reported that its prediction markets topped $200 million in annualized revenue in the third quarter, while five Web3 projects show differences in trading structure and contract resolution.

Coinbase also reported that daily traders on its product rose more than 60% from the previous quarter. Its event contracts are operated by Kalshi, a CFTC-designated contract market. The figures describe Coinbase’s product, not total Web3 market activity.

“Prediction markets have been one of the fastest-growing products in Coinbase history,” Coinbase co-founder and CEO Brian Armstrong said.

The five projects are not ranked by volume. Four operate markets directly, while Azuro provides infrastructure other applications can use.

Separate exchanges and on-chain trading

Polymarket has a blockchain-based international exchange and a separate U.S. exchange. U.S. residents must use the Polymarket US app. The CFTC designated QCX LLC, doing business as Polymarket US, as a contract market on July 9, 2025. Polymarket’s public dashboard combines data from both exchanges, so its totals do not isolate activity on the international blockchain-based venue.

Opinion operates on BNB Chain and supports a central limit order book. Opinion AI resolves most markets.

Different market-resolution models

Predict.fun launched in 2025 as a BNB Chain-native platform. It uses UMA’s Optimistic Oracle. Uncontested markets resolve in about two hours, while challenged outcomes go to a token-holder vote. The platform also offers yield mechanisms using Venus Protocol.

Limitless Labs operates an on-chain exchange on Base. A five-minute Bitcoin (BTC) market uses Chainlink’s BTC/USD data stream to determine its outcome. A contract-calibration study published Oct. 25 also examined Limitless.

Infrastructure for other applications

Azuro is a protocol that other applications can integrate. It uses shared liquidity pools and lets third parties build their own interfaces on top.
