Prediction markets post record $123.6B month, site traffic rivals Bloomberg and Politico

October notional trading volume reached $123.6B, roughly 1.5 times the combined $82B traded across all of 2024 and 2025. The author notes that even under a more conservative measure counting only cash buyers paid for contracts, October still exceeded all of 2025, and nearly every metric set an all-time high after September's records. Per Similarweb, Kalshi drew 28M site visits and Polymarket 38M, comparable to Bloomberg (38M) and Politico (32M), underscoring the author's view that prediction markets function as media properties as much as markets.
