Sports Betting Market Expands as More US States Go Live in 2026

The US sports betting landscape is undergoing a period of extraordinary growth in 2026, with several additional states launching fully regulated online sportsbook operations in the first half of the year. This expansion represents one of the most significant shifts in the American gambling market since the Supreme Court struck down the federal ban on sports wagering in 2018.

Industry analysts project that the total US sports betting handle will exceed $150 billion by the end of 2026, up from approximately $120 billion in 2025. The entry of new state markets accounts for a significant portion of this projected growth, as each new jurisdiction brings millions of potential bettors into the legal market.

Major national and international operators are competing aggressively for market share in the newly opened states, with promotional spending reaching record levels. Welcome bonus offers, enhanced odds, and loyalty programs have become standard tools in the battle for customer acquisition, though regulators in some states have begun scrutinising the scale of promotional activity.

Mobile betting continues to dominate, accounting for roughly 80% of all wagers placed. The convenience of smartphone-based betting has proven particularly effective at converting sports fans into regular bettors, with the NFL season historically serving as the catalyst for player acquisition.

The affiliate marketing sector has grown in parallel with the expansion of legal sports betting, with a growing number of sports media companies and content creators establishing formal partnerships with licensed sportsbook operators.
