World Cup boom sends Polymarket volume up 300% while Kalshi sets open interest records

The World Cup has driven a significant surge in betting activity, with Polymarket's trading volume jumping 300% last week. Kalshi, another betting platform, saw its aggregated open interest hit a record $1.16 billion, marking the first time it surpassed the billion-dollar threshold. This boom reflects the growing interest in sports betting, especially during major global events, and highlights the expanding market for decentralized and traditional betting platforms alike. The increased activity suggests a broader trend of people engaging more with sports betting markets.
