Prediction markets are undergoing a radical transformation, driven by the rise of ultra-short-duration contracts and new AI-powered research services. On-chain data from Dune Analytics reveals that Polymarket's "fast markets"—contracts as short as 5 minutes—have exploded in popularity, now accounting for 20–25% of the platform's overall trading volume and reshaping it into a high-velocity derivatives-like venue.
The acceleration is dramatic. When 5-minute markets launched in early February 2026, they immediately cannibalized longer segments, with $258 million flowing in during one week alone. By early March, 5-minute markets hit a weekly peak of $385 million. Over an eight-week period from mid-February to late March, these ultra-short contracts generated $2.3 billion in notional volume.
Bitcoin dominates this fast-paced activity, commanding 77% of fast-market volume in late March. Ethereum follows at 13%, with Solana and XRP each representing 5–6%. Dogecoin, BNB, and Hyperliquid remain marginal players. Automation is key, with bots responsible for 55–62% of volume in the 5- and 15-minute markets, compared to just 31% in slower contracts.
The shift has proven lucrative. Following the introduction of taker fees on January 7, 2026, Polymarket generated $23.7 million in net fee revenue in just 83 days, averaging $286,000 daily. Bitcoin alone contributes 58% of these fees.
In a parallel development, cryptocurrency investment firm ProCap Financial, led by Anthony Pompliano, has partnered with regulated prediction market exchange Kalshi to launch a unique research service. The service, integrated into ProCap's existing ProCap Insights platform, will use AI tools to analyze Kalshi's real-time, crowd-driven data, producing reports on market trends, trading strategies, and mispriced contracts.
"Kalshi Research’s prediction market data paired with our AI agents is a powerful combination," said Pompliano. Kalshi CEO Tarek Mansour added that the partnership aims to bring "wisdom-of-the-crowds intelligence directly to financial research." Kalshi's own research claims its markets outperformed Wall Street consensus forecasts by 40% across various conditions.
The regulatory landscape is also shifting in favor of these markets. In March 2026, the Commodity Futures Trading Commission (CFTC) issued guidelines promoting new event contracts and requested public input on a comprehensive framework. Furthermore, a federal appeals court ruled on April 6, 2026, that federal law supersedes state gaming regulations for Kalshi's sports contracts, a significant legal victory.
