The wallet placed wagers on three matches in two days, with its biggest hit coming from South Africa vs. Canada and its only profit from Croatia vs. Ghana.
A newly created wallet identified as "coldsway" lost more than $3.97 million after placing prediction market bets on three World Cup matches over two days, Onchain Lens said on June 29. The largest single loss was about $3.14 million on South Africa vs. Canada after Canada won, followed by another roughly $1.97 million loss on Colombia vs. Portugal. The wallet’s only winning position generated about $1.06 million on Croatia vs. Ghana. The activity highlights how prediction markets can produce outsized gains or losses over a short period when large wagers are concentrated on a small number of outcomes.
