Polymarket and Kalshi platforms are vying for dominance.
According to Bernstein analysts, clearer regulatory rules are transforming prediction markets from rigid, exchange-managed contracts to flexible platforms powered by cryptocurrency and blockchain. At the center of this shift, Polymarket and Kalshi are vying for dominance.
Kalshi has built its business on a regulation-focused model, securing key licenses from the CFTC and even winning a federal lawsuit over political contracts.
As a centralized exchange based in the US, it offers binary options on events in politics, economics, weather, and sports, requiring full KYC and AML compliance.
Polymarket, on the other hand, began as a decentralized platform built on Polygon and Ethereum, evolving into the largest global prediction marketplace, with peak volumes of $2.6 billion in November 2024.
Long banned in the US following the CFTC's actions, it is now preparing for a regulated return by relaunching through the licensed QCEX exchange with KYC-compliant access.
"By acquiring the licensed derivatives exchange QCEX, [Polymarket] has secured a path to US markets," Bernstein analyst Gautam Chhugani wrote in a note.
Kalshi, meanwhile, is moving in the opposite direction, announcing partnerships with Solana and Base to integrate blockchain and expand into markets outside the US, while strengthening its distribution through crypto ecosystems.
Trading volumes highlight the intensity of the competition. As of September, Kalshi's monthly volumes exceeded $1.3 billion, nearly double Polymarket's $700 million.
Together, they have already executed $12 billion in trades in 2025, with activity expanding beyond political bets to sports, cultural events, and corporate results.
"Strong regulatory clarity paves the way for the evolution of existing markets into a comprehensive prediction market," Chhugani said.
Partnerships are also driving growth. Polymarket has been named an official prediction partner of X (formerly Twitter, blocked in Russia), integrating its markets directly into the social media platform. Kalshi is working with xAI to implement Grok's AI-powered odds analysis.
Robinhood and Coinbase are also getting involved—Robinhood is partnering with Kalshi to create a full-fledged prediction hub, recording $1 billion in volume in the second quarter, while Coinbase announced plans to add prediction markets as part of its "universal exchange" vision.
For users, the convergence of cryptocurrency, AI, and social media is changing the way they consume and respond to information.
Prediction markets not only provide alternative signals to traditional news and surveys, but also provide liquidity for highly specific contracts, such as contracts on Nvidia data center revenues or Federal Reserve monetary policy decisions.
