US sports betting reached a new milestone in 2025, with Americans legally wagering $166.94 billion on sports, according to the American Gaming Association. The total represented an 11% year-over-year increase, setting another industry record while highlighting a significant shift from the rapid expansion seen in previous years.
Sports betting revenue climbed 22.8% to $16.96 billion, generating $3.71 billion in tax revenue for state governments. Legal sports betting is now available across 39 states, Washington D.C., and Puerto Rico, covering more than 90% of the US adult population.
New York remained the country’s largest sports betting market, producing approximately $1.30 billion in tax revenue alone, while the ten largest states accounted for nearly 70% of all wagers placed nationwide.
Industry Enters a More Mature Phase
The latest figures suggest the US sports betting market has moved beyond its early expansion stage.
Following the 2018 legalization of sports betting, annual growth regularly exceeded 160% as new states launched regulated markets. Today, with most major jurisdictions already online, annual growth has moderated to around 11%, reflecting a more mature and competitive industry.
Online betting continues to dominate the market, with mobile platforms accounting for the vast majority of wagers and driving long-term consumer adoption.
Operators Shift Their Growth Strategy
As geographic expansion slows, operators are placing greater emphasis on customer retention, product innovation, and operational efficiency.
Rather than competing through aggressive market launches, sportsbooks are investing in live betting, personalized experiences, pricing models, and risk management to increase player engagement and wallet share. Technology infrastructure and real-time data have also become increasingly important as operators look to deliver faster, more reliable betting experiences.
At the same time, emerging products such as prediction markets are creating new competitive pressure. Platforms including Kalshi and Polymarket continue to gain momentum, adding another dynamic to the evolving US betting landscape as operators compete for player attention in an increasingly mature market.
