Here is what happened this week in prediction markets.
ANALYSIS | World Cup 2026 Broke Every Prediction Market Record
Kalshi's World Cup-specific markets generated over $13 billion in trading volume during the tournament. Total trading across all prediction market exchanges, including international platforms, surpassed $50 billion -- making 2026 the single largest prediction market event in history. The winner market alone saw approximately $1.4 billion in notional trading volume.
TRADING | How SwissToney Secretly Ran $500M Through Polymarket and SportsRadar
SwissToney, an anonymous trading entity, quietly moved more than $500 million in prediction market volume through Polymarket with help from SportsRadar pricing infrastructure. The strategy revealed how sophisticated players are building data moats on public prediction markets -- and represents the first reported case of a major sports data vendor directly embedded in the trading workflow of a top prediction market platform.
MARKETS | Kalshi vs. Polymarket: Who Won the World Cup?

Kalshi generated approximately $1.4 billion on its winner market alone. The results signal a significant shift in the competitive landscape between the two leading US platforms.
REGULATION | Minnesota Bans Prediction Markets. Other States Are Watching.
