The World Cup drives the prediction market, Polymarket turnover surges, and Kalshi's open interest contracts reach new highs

According to The Block, it is predicted that the market platform Polymarket will have a turnover of over 2 billion US dollars in the first 10 days of the Soccer category after the start of the World Cup, an increase of about 300% compared to the previous 10 days. The daily turnover of this category will increase from 53 million US dollars to about 220 million US dollars. During the same period, the compliance prediction platform Kalshi aggregated the size of open contracts, which exceeded 1.16 billion US dollars for the first time last week, an increase of about 350% since the beginning of the year. The overall open interest size of Polymarket remained relatively stable during the World Cup period, while Kalshi is regulated by the US Commodity Futures Trading Commission and supports direct USD deposits, attracting US institutions and high net worth users to hold long-term positions. Its positioning is to benchmark compliant sports betting platforms such as DraftKings and FanDuel.
