The World Cup kicks off: A look at the “huge wins” and “massive losses” in prediction markets

作者：溫瑟（@wenser2010 )

The World Cup has officially kicked off, and prediction markets are witnessing an exponential surge in trading volume.

根據一個 report from asset management giant Bernstein, the 2026 FIFA World Cup is expected to generate up to $10 billion in consumer transaction volume for sports betting and prediction markets, along with over $3 billion in incremental capital. Earlier, various prediction markets and exchanges launched incentive campaigns to capitalize on this opportunity for attention and volume. With the group stage underway, upsets, draws against underdogs, and dark horse breakthroughs have become the norm, bringing both “instant wealth” and “massive losses” for prediction market participants.

Odaily reminds readers that upsets are common in prediction markets for sports events, and copy-trading should be approached with caution.

Representative Accounts with World Cup Losses: $1 Million Loss from Upset, Over $1.8 Million Loss on Argentina Not Winning

In prediction markets, for every winner, there is a loser. The counterparty always exists, just in a different form.

Spain vs. Cape Verde: 0-0 Draw Leads to $1 Million Loss for Single Account

Polymarket data shows that account @betoor619 (address: 0x70088c990ffae782c699b9250f5aa6cbe4e3c666) bought “Spain to win” in the World Cup group stage match between Spain and Cape Verde. The match ended 0-0, resulting in a loss of $999,000 for the user.

Notably, the user entered the trade at a price of 92 cents, essentially risking a $1 million principal for a potential $8,500 profit. This seemingly safe bet turned into a massive loss due to an upset, largely thanks to Cape Verde’s 40-year-old goalkeeper making 7 incredible saves and their rock-solid defense.
