In June, the nominal trading volume in prediction markets surpassed $50 billion for the first time in history. Nominal trading volume increased by 75% month-over-month, driven by the insane hype and traffic from the World Cup. Prediction markets continue to follow the 'strong get stronger' trend: - Kalshi hit a staggering $33 billion in nominal trading volume in a single month, up over 80% MoM. - Polymarket reached $14.5 billion, making it one of only two prediction markets to break the $10 billion mark in a single month. - Rothera was the biggest highlight of the month, hitting $2.1 billion, showcasing Robinhood's strength.
