A man bet $325 on a golf tournament and believed he had turned it into $14.2 MILLION. DraftKings voided all five bets and refunded his money. He sued, arguing the sportsbook changed the rules after accepting his wagers. – Nicholas Bavas, 37, from Dallas County, Iowa, spotted an opportunity during the 2024 Pebble Beach Pro-Am as bad weather threatened to cut the tournament short. – On February 3, he placed five bets predicting how the golfers would finish. – The bets were worth a combined $325, with potential payouts totaling $14.2 MILLION. – DraftKings was still accepting wagers even as the weather threatened the final round. – Bavas bet on the positions of golfers who were leading after the third round. – The tournament was eventually called after 54 holes, making those standings the official results. – According to Bavas and his lawyers, all five bets matched the final standings. – But DraftKings voided them and returned his stakes instead of paying the potential winnings. – This won't happen with prediction markets. – On a prediction market, traders take positions against other participants, with payouts determined by the market's contract rules and resolution process. – You're not relying on a traditional sportsbook to honor a winning bet under its house rules. – Bavas argued that DraftKings' rules at the time didn't allow the company to void his particular type of multi-player parlay. – His lawyers also argued that DraftKings changed its rules after the tournament to address similar situations. – DraftKings disputed his claim, arguing that its house rules allowed it to void wagers under these circumstances. – Bavas sued in 2025, seeking the $14.2 MILLION he believed he was owed. – But the case didn't end in his favor. In July 2026, the court ruled for DraftKings, rejecting his bid to recover the money. He risked $325 chasing $14.2 MILLION. The tournament ended early, his picks lined up with the final standings, and he took the fight to court. In the end, DraftKings won the legal battle, and Bavas walked away without the millions he was chasing.
