The U.S. iGaming market is experiencing rapid growth and evolution. From state-by-state legalization to the increasing influence of cryptocurrency and a federal tax debate, 2025 is shaping up to be a pivotal year. While legal sports betting and online casinos continue to boom, challenges remain, including a significant illegal market and concerns about problem gambling. Here’s a breakdown of the latest developments transforming the U.S. gambling landscape.
The push for legal iGaming isn’t slowing down. Several states are actively considering or implementing changes to their gambling laws. Massachusetts is currently evaluating HB 332/SB 235, which proposes legalizing online casino gaming and imposing a 20% tax on the revenue generated, earmarked for crucial services, including programs to prevent gambling problems. Maine is poised to join the ranks of states with legal online casinos, with LD 1164, which taxes online casino revenue at 18%, awaiting Governor Mills’ signature.
However, not all states are moving at the same pace. California, a potentially massive market, is still a sticking point. Failed 2022 ballot initiatives (Props 26 & 27) have created hurdles, but a potential 2026 ballot could finally unlock the state’s potential. Meanwhile, Nebraska, seeing a doubling of casino revenue in 2024, is hinting at a possible move toward mobile sports betting soon.
A recent piece of federal legislation, dubbed the “One Big Beautiful Bill Act,” has sparked controversy among professional gamblers. The act limits gamblers’ loss deductions to 90% of winnings, a reduction from previous allowances. It has prompted concerns that professionals may move their activities to offshore markets where they can deduct 100% of their losses.
Responding to the backlash, Rep. Dina Titus (D-NV) introduced the FAIR BET Act, a bipartisan effort to restore the 100% loss deduction for gamblers. The aim is to keep betting within regulated U.S. markets and maintain the revenue stream generated by professional players. This debate highlights the delicate balance between maximizing tax revenue and ensuring industry continues to be competitive.
Despite being a typically slower season, the sports betting market continues its growth. New York exceeded $2 billion in betting handle in May 2025, while New Jersey surpassed $1 billion. A recent report reveals that only 25% of total U.S. gross gambling revenue comes from legal platforms. This indicates a significant presence of the illegal gambling market, fueled by convenience, variety, and often, a lack of strict regulation.
This underscores the need for continued expansion of legal options and effective regulation to draw bettors away from unregulated platforms.
The U.S. iGaming market is also being shaped by technological advancements and changing consumer habits. New York gamblers are increasingly turning to cryptocurrency on unregulated platforms, creating a regulatory gap that states are beginning to address.
Social media giants like Meta are tightening oversight of gambling ads, responding to pressure from regulators and consumer advocates. Leading iGaming companies are expanding their online casino offerings in Michigan, New Jersey, and other states, offering a wider range of games and betting options.
A potentially significant policy shift is brewing within the NCAA. The organization is considering allowing student-athletes to bet on professional sports, a move that is going to be finalized by October 2025. It brings the NCAA more in line with the broader trend of sports betting acceptance and could further boost engagement in the market.
