But after a 7-0 victory in Game 1 against the Sharks, the Knights emerged as sole favorites to win the Cup with odds of 7-2, by William Hill. The odds dropped steadily throughout the season, as the Knights set an N.H.L. record for most points in a season by an expansion franchise. Over the last year, William Hill, the operator of more than 100 full-service and kiosk locations in Nevada, has booked 350 bets on the Knights to win the Cup at odds of at least 100-1.
On Oct. 8, 2017, two days before the team’s regular-season home debut, a bettor placed a $200 wager with William Hill on the Knights to win the championship at odds of 200-1. On Oct. 25, hours after the Golden Knights improved to 7-1, William Hill accepted a $1,000 bet at 50-1.
William Hill also began a promotion this spring, where it will award new members with a $5 bonus for every win by the Golden Knights in the playoffs. The bonus represents a sliver of the company’s seven-figure liability, a William Hill spokesman said.
For bettors unsure whether the team will pull off the miraculous feat, another option exists. More than a dozen holders of Golden Knights’ future bets have sold their tickets on PropSwap.com, a Las Vegas-based start-up that serves as an intermediary between buyers and sellers. Prop Swap, which was founded in 2015, does not purchase futures tickets, but sets a price that satisfies both parties, then receives a commission for brokering the transaction.
Before Game 3 of the World Series, a bettor sold a $3,000 futures wager placed on the Astros earlier in the season for $13,600. When Houston won in seven games, the buyer collected $31,000, on odds of 2.28-1.
The majority of Prop Swap tickets on the Knights have sold in the range of $500 to $2,000, with the bulk of transactions occurring in March after the team clinched a playoff spot.
