Surge in Trading Volume: Prediction market firms Polymarket and Kalshi experienced a significant increase in trading volume, exceeding $2 billion for the week ending October 19, driven by interest in sports events like MLB playoffs and the NHL season.
Impact of NFL and College Football: Over 60% of the trading volume on these platforms was attributed to NFL and college football contracts, indicating a strong interest in these sports.
Partnership with Robinhood: Kalshi's new partnership with Robinhood Markets is believed to have contributed to attracting new users to the prediction market industry.
Analyst Insights on Competition: Needham analyst Bernie McTernan expressed confidence in DraftKings and FanDuel's offerings over prediction markets, suggesting that the growth in prediction market volume may not directly impact established online sports betting operators.
