Spain-Argentina World Cup final drives nearly $2 billion in Kalshi and Polymarket volume

The Spain-Argentina World Cup final generated about $1.977 billion in match-specific trading volume across prediction markets Kalshi and Polymarket, while the broader World Cup winner market on Polymarket climbed to a record $4.3 billion, surpassing the platform’s previous high set during the 2024 U.S. presidential election. Spain beat Argentina 1-0 after extra time on Sunday, with Ferran Torres scoring in the 106th minute to secure the country’s second World Cup title. Ahead of kickoff, the two platforms independently converged on nearly the same implied odds despite separate order books, liquidity pools and user bases: Polymarket priced Spain at roughly 59% and Argentina near 40%, while Kalshi showed Spain at 59.6% and Argentina at 40.4%. Post-tournament analysis on Polymarket showed highly uneven outcomes. On-chain analyst defioasis.eth’s review of more than 194,000 wallets found nearly 130,000 addresses, or about 66.7%, posted losses. Most of those losses were small, with 114,000 addresses down less than $100 each and average losses under $10, while only five wallets made more than $1 million. One of the largest final-specific losses came from trader gud.hl, who lost his full $1.23 million Argentina position after previously sitting on more than $5 million in unrealized profit. Other tournament trading showed how quickly soccer draws punished heavily favored positions. Trader coldsway lost $11.6 million in ten days, winning only four of 15 bets, while FlickRaw lost about $4.2 million in under 24 hours on two matches that both ended level. User betoor619 lost nearly $1 million after backing Spain to beat Cape Verde at 92% odds, and Canadian rapper Drake lost a $1.5 million USDT bet on Argentina to win the final in regulation time after the match went to extra time. On the winning side, fishalive turned roughly $400,000 into nearly $9 million by betting Spain would not beat Cape Verde, another trader made $9.24 million in a single day by correctly calling four outcomes, and trader yamal19 made $1,349,881 net on Spain in the final. The record World Cup activity also lifted overall platform volumes. Polymarket processed $10.8 billion in June and $5.8 billion so far in July, while Kalshi handled $25.3 billion in July so far and said the tournament brought 3 million new users. Earlier company figures showed Kalshi’s total platform volume rose from $6.67 billion on June 22 to $24.2 billion on July 14, with its single World Cup champion market exceeding $1.2 billion, as the event pushed prediction trading further into the mainstream sports-betting conversation.
