US Sports Betting Market Size: Revenue, Handle & Growth Data for Bettors
The Industry You’re Betting Into Generates $17 Billion a Year
Most bettors think about their next pick. I think about the machine behind it. When you place a $50 moneyline bet on a Tuesday night Guardians game, that bet flows into an industry that generated $16.96 billion in revenue in 2025 alone – a 22.8% jump from the year before. Understanding the scale of this market is not just trivia. It directly affects the odds you receive, the markets available to you, and the long-term trajectory of the betting landscape you operate in.
The US sports betting industry has grown from essentially zero legal revenue in 2018 to one of the fastest-expanding consumer markets in the country. That growth has implications for bettors at every level: more competition among sportsbooks means better odds and more prop markets. More legal states mean more volume, which means more liquidity and tighter lines. The market’s size is not abstract – it shapes the environment you bet in every day.
Revenue vs. Handle: What Each Number Tells You
Two numbers define the sports betting market, and most people confuse them. Revenue is what the sportsbooks keep after paying out winning bets – $16.96 billion in 2025. Handle is the total amount wagered – $166.94 billion in 2025, an 11% increase over 2024. The relationship between these numbers tells you something important about the market’s efficiency and the bettor’s position within it.
Revenue divided by handle gives you the hold percentage – roughly 10.2% in 2025. That means for every $100 wagered across all sports bets in the US, the sportsbooks kept about $10.20. That hold percentage has been rising over time, driven in part by the growth of parlays, which carry a higher effective margin than straight bets. From a bettor’s perspective, the rising hold is a headwind: the house is taking a larger slice of the overall pie.
The cumulative handle since PASPA’s repeal in 2018 has now exceeded $600 billion. That is not a typo – over half a trillion dollars has been legally wagered on sports in the US in less than a decade. The handle growth has been driven by two factors: the expansion of legal markets (from a handful of states in 2018 to 38 plus DC by 2026) and the shift to mobile betting, which now accounts for roughly 90% of all wagers.
For baseball bettors specifically, MLB’s share of the overall handle typically runs between 8% and 12% depending on the season. During the summer, when MLB is the only major sport in daily action, that share peaks. Baseball’s handle percentage is smaller than football’s or basketball’s, but the sport’s daily volume – 15 games per day for six months – means the absolute dollar amount wagered on MLB is substantial. More importantly, the baseball market is deep enough to support sharp action without the sportsbooks cutting limits as aggressively as they do on niche markets.
$3.71 Billion in Tax Revenue – and Rising
The tax side of sports betting growth matters to bettors because it shapes the regulatory environment. States that generate significant tax revenue from sports betting have a financial incentive to keep the market open, expand it, and attract more operators. States still debating legalization are watching the revenue numbers closely.
Tax revenue from sports betting hit $3.71 billion in 2025, a 32.4% increase over 2024. The growth rate is staggering when you zoom out: quarterly tax revenue from sports betting rose 382% between 2021 and 2025, from $190 million per quarter to over $917 million. These are not marginal numbers – they fund state programs, education budgets, and infrastructure projects.
The tax revenue argument has been the most effective tool for legalization advocates. When a state sees neighboring markets generating hundreds of millions in tax revenue while their own residents drive across the border to bet legally, the economic pressure to legalize becomes difficult for legislators to resist. This dynamic has driven the expansion from a handful of states in 2019 to the current landscape where the vast majority of Americans live in a state with some form of legal sports betting.
For bettors, the practical implication is optimism about market expansion. States like California and Texas – the two largest by population – have not yet legalized online sports betting. When they do, the handle and revenue numbers will jump significantly, likely driving more competitive odds and wider market availability. The responsible gambling infrastructure needs to grow alongside the market, but the direction of regulatory travel is clearly toward expansion.
Where the US Market Sits Globally
The global sports betting market was valued at roughly $111.9 billion in 2025, with a projected compound annual growth rate of 8.13% through 2034. The US now accounts for a significant and growing share of that global market, having gone from zero legal handle to the single largest regulated market in under a decade.
The online segment represents 67.5% of the global market, and that share is growing as mobile platforms expand in emerging markets. In the US, the online share is even higher – around 90% – because the legal market was built in the smartphone era rather than transitioning from a retail base. This mobile-first structure gives US bettors access to more markets, more live betting options, and more competitive odds than bettors in many other countries where retail shops still dominate.
Soccer leads global betting handle with a 25.4% share, followed by basketball and baseball as the fastest-growing categories at roughly 10% annual expansion each. For MLB bettors, the global growth context means the analytical tools, data infrastructure, and betting technology will continue improving. More money flowing into the ecosystem funds better odds comparison tools, deeper statistical databases, and more sophisticated data-driven pick platforms – all of which benefit informed bettors.
The competitive dynamics are also worth watching. As the market matures, sportsbooks compete on product quality rather than just promotional offers. That competition has driven improvements in live betting interfaces, prop market depth, and odds competitiveness. For baseball bettors who compare prices across books, this competition is an ongoing tailwind – the more operators fight for market share, the better the odds become for consumers who shop around.
What share of US sports betting handle goes to baseball?
MLB typically accounts for 8-12% of total US sports betting handle, depending on the time of year. During summer months when MLB is the primary daily sport, baseball’s share peaks. While this is smaller than football or basketball, the absolute volume is substantial because MLB offers 2,430 regular-season games compared to the NFL’s 272, creating consistent daily betting opportunities across a six-month season.
How does the US sports betting market compare to Europe’s?
The US has rapidly become the largest single-country regulated sports betting market by handle. European markets are more mature, having operated legally for decades, but are fragmented across dozens of different regulatory frameworks. The US market’s mobile-first structure and concentrated platform competition (dominated by a handful of major operators) produce some of the most competitive odds and widest market availability globally.
