Prediction markets achieved a record-breaking $12 billion in monthly trading volume during January 2026, according to data reported by Wu Blockchain. This milestone marks a significant expansion of event-based trading into mainstream crypto activity. The surge was driven by multiple platforms, with Kalshi, Polymarket, Opinion, and Probable each posting over $1 billion in volume, indicating a broad-based increase in participation rather than reliance on a single venue.
On-chain fee data from Dune Analytics, sourced via Gate Research's dashboard, revealed that January activity generated more than $11 million in fees. Opinion led the fee generation with $6.14 million, followed by Polymarket at $2.62 million. This fee distribution highlights where traders concentrated their liquidity and suggests varying levels of engagement and settlement activity across different prediction market platforms.
A key development fueling this growth was the January launch of a U.S.-based prediction market platform by Coinbase in partnership with Kalshi. The partnership provides regulated access to event-based trading, where users can take positions on predefined outcomes like political elections, sports results, and macroeconomic indicators. Kalshi, which reportedly reached an $11 billion valuation, uses a structure of "yes or no" event contracts that settle based on real-world outcomes, with prices reflecting market-implied probabilities.
The report framed Coinbase's move as part of its strategy to build an "everything exchange" model, expanding its product categories. This entry by a major regulated U.S. exchange is expected to pull incremental traders toward prediction markets and could subject the sector to greater regulatory scrutiny due to the sensitive nature of some contract topics.
The January record sets a high benchmark for the sector, which often experiences volatile flows tied to major event cycles. The outlook now focuses on whether the billion-dollar volume platforms can sustain these levels and if the new distribution channel through Coinbase will lead to sustained growth and improved liquidity across prediction markets.
