Online Sports Betting: A Long Term Wager

Now that the U.S. Supreme Court has ruled that states can’t ban online sports betting, we wanted to help Barron’s readers prepare for the rise of sports betting as the next big alternative asset class. For the World Cup final match on Sunday, when Croatia will face France, the French are strong favorites. At the Online Betting bookmaker bet365 on Friday, it cost you 250 to win 100 on a French victory, while you had to risk only 100 to win 200 on Croatia.

I left out the dollar signs on those odds because they can’t take Americans’ bets. The difference of 50 in the payoffs is the sports-bookmaker’s "vigorish," which corresponds to the spread between Buy and Sell quotes that provide the profit for market makers in our financial markets. For sports bettors, the Vig is more expensive than the spreads on a typical Wall Street stock trade.
