Polymarket has reported unprecedented growth in October, achieving record highs in trading volume, active traders, and new market launches. The platform saw over 477,000 active traders and surpassed $3 billion in trading volume. This surge was fueled by the announcement of the POLY token, plans to re-enter the U.S. market, and a potential $15 billion fundraising round. The growth in Polymarket's activity aligns with a broader expansion in the prediction market sector, highlighted by Kalshi's report of over $4.4 billion in trading volume for October. These developments underscore the increasing interest and investment in prediction markets.
