A $20 Billion Valuation: Kalshi and Polymarket in an Arms Race?
A potential "arms race" is brewing in the prediction market sector, with industry leaders Polymarket and Kalshi each reportedly in funding talks at valuations around $20 billion. This represents a near doubling of their respective $12 billion and $11 billion valuations from late 2025.
As of February 2026, the global prediction market has reached a cumulative notional trading volume of $127.5 billion. Polymarket leads with $56.07 billion, followed closely by Kalshi at $44.71 billion, together commanding 79% market share. Their growth trajectories differ: Kalshi has experienced explosive user growth, with monthly active users surging from 600,000 to over 5.1 million in 2025, while Polymarket's user growth has been steadier, peaking around 700,000 monthly active users.
Kalshi's trading volume skyrocketed over 1100% in 2025, largely driven by sports contracts which account for 81% of its volume. It has secured key partnerships with platforms like Robinhood, which contributed over 50% of its volume in late 2025, and media outlets like CNBC and CNN.
Polymarket maintains a stronghold in political and crypto event markets. It has formed significant partnerships with X (formerly Twitter), ICE (for a strategic investment up to $2 billion), and the UFC for exclusive prediction market data. Both platforms are also official partners of the NHL, and their data is integrated into Google's search and finance products.
Their divergent strategies—Kalshi's focus on USD-compliant trading and Polymarket's crypto-native, global event coverage—are collectively pushing prediction markets into the mainstream as vital information and risk-management platforms. With potential new funding and major upcoming events like the World Cup and the US elections, both platforms are poised for a record-breaking year in 2026.
