Kalshi and Polymarket post strongest months yet with nearly $10 billion in combined November volume

Centralized and on-chain prediction markets, specifically Kalshi and Polymarket, recorded their strongest month ever in November, surpassing nearly $10 billion in combined trading volume. Kalshi's spot volume rose 32% month-over-month to $5.8 billion, while Polymarket's volume increased 23.8% to over $3.7 billion. This surge continues a breakout year for the two platforms, which now dominate the sector. The growth is supported by increasing institutional interest, capital formation—Kalshi recently doubled its valuation to $11 billion—and strategic developments, such as Polymarket's regulatory approval to resume U.S. operations and new distribution partnerships with entities like Yahoo Finance and UFC.
