PANews reported on October 14th that according to The Block, in September, the combined trading volume of prediction markets Kalshi and Polymarket hit a record $1.44 billion, reflecting the mainstream market's growing interest in the emerging speculative field of prediction markets. Last month, Kalshi's market share peaked at 60% when it faced Polymarket in September, a significant reversal from the beginning of the year when Polymarket dominated trading activity. Kalshi's recent surge in trading volume is partly due to its partnership with Robinhood. This integration has enabled Kalshi to reach Robinhood's large retail user base, which may explain the platform's growing market share.
