Most world cup traders won less than $5 on Polymarket while FIVE wallets walked away with millions

Most world cup traders won less than $5 on Polymarket, highlighting how a new wave of sports-prediction trading delivered highly concentrated results rather than broad, consistent gains. The article says the Spain-based World Cup outcome settled the largest sports-related winner markets on Polymarket and Kalshi, bringing prediction trading closer to the center of global sports-betting. Available platform data put cumulative tournament-linked volume at about $5.57 billion, with Polymarket at roughly $4.28 billion and Kalshi about $1.29 billion. It also cites H2 Gambling Capital estimating prediction markets were around 27% of legal US sports-betting volume during the tournament. Dune Analytics reviewed 194,422 Polymarket addresses: 66.7% finished in the red, and only 43 addresses lost more than $100,000 each, driving $15.19 million of combined losses.
