A $166 Billion Industry Where Baseball Claims Its Share

Numbers this large feel abstract until you realise they directly affect the lines you bet every night. The total volume of legal sports bets placed in the United States reached $166.94 billion in 2025 – an 11% increase over the previous year. That is not a projection or an estimate from a bullish analyst. That is actual money that moved through regulated sportsbooks in a single calendar year. Understanding where MLB sits within that torrent of capital changes how you interpret the lines, the odds, and the market dynamics around every game.

I started paying attention to market-level data around 2019, shortly after the repeal of PASPA opened the floodgates. Back then, the handle numbers were a fraction of what they are today. Watching the industry grow has not just been professionally interesting – it has been practically useful. The more money flows into a market, the tighter the lines become, the faster the books react to sharp action, and the narrower the windows of value. Knowing the scale of the market informs how I approach the game.

US Sports Betting Revenue and MLB’s 15% Handle Share

US sports betting revenue hit $16.96 billion in 2025, a 22.8% jump from 2024. Bill Miller, president and CEO of the American Gaming Association, described the results as exceptional for consumers, operators, and the communities that benefit from tax revenue. Those tax contributions are not trivial – they fund public services in the 38 states and districts where sports betting is now legal.

MLB accounts for approximately 15% of the total US sports betting handle. That places it behind football (both NFL and college) and basketball but ahead of hockey and soccer. The 15% figure translates to roughly $25 billion in annual MLB-specific handle – a staggering number that ensures the baseball betting market is deeply liquid and aggressively priced by the major operators.

Since the repeal of PASPA in 2018, more than $600 billion in cumulative legal sports bets have been placed in the United States. MLB’s share of that cumulative figure is smaller than football’s, but baseball’s daily game volume – up to 15 games per day across a six-month season – creates a betting frequency that no other American sport can match. One in five American adults made at least one sports bet in the past 12 months, and a meaningful portion of those bets landed on baseball.

Total commercial gaming revenue across the US reached $78.72 billion in 2025, a 9.2% increase. Sports betting is the fastest-growing segment within that total, and MLB is growing alongside it. The practical implication for bettors is that the market is maturing rapidly. Lines are sharper than they were five years ago, closing line value is harder to capture, and the days of easy money on obviously mispriced baseball games are largely over. The edges that remain are smaller but still real – they just require more rigorous analysis to find.

UK Betting Market: GGY, Online Growth, and MLB Availability

The UK sports betting market generated GBP 2.48 billion in annual gross gaming yield by early 2026. Ten percent of UK adults actively participate in online sports betting, and the remote sector’s online GGY grew 8% year-on-year to GBP 1.42 billion in the second quarter of 2025 alone. The market is mature, heavily regulated, and increasingly international in its coverage – which means MLB availability on British platforms is broader than it has ever been.

Projections place the UK sports betting market at $21.32 billion by 2030, with a compound annual growth rate of 11.4%. That growth is driven by mobile penetration (95% of UK online gambling happens from home, and the 18-24 age group shows 76% mobile usage for betting), expanding international sports coverage, and the regulatory framework that gives punters confidence in the legitimacy of licensed operators.

For MLB-specific betting from the UK, the key development is market depth. Five years ago, UK books offered moneyline and totals on a handful of MLB games per day. Today, the major platforms cover every game with props, run lines, first-five-innings markets, and futures. The odds are displayed in decimal format as standard, and GBP deposits and withdrawals are seamless. The barrier to entry for UK bettors interested in MLB has never been lower.

Industry Growth Projections and MLB’s Position

The overall US commercial gaming revenue figure of $78.72 billion tells a story of an industry that has moved far beyond Las Vegas. Sports betting is now legal in 38 jurisdictions, and each new state that comes online adds handle, liquidity, and competitive pressure among operators. That competition benefits bettors because it pushes odds tighter and promotions richer as operators fight for market share.

MLB’s position within this growth trajectory is secure but not dominant. Baseball will never match the NFL’s betting handle because football’s weekly scarcity creates concentrated demand. But baseball’s daily volume provides something football cannot: a laboratory for consistent, repeatable betting strategies tested across thousands of games per season. For analytical bettors, that consistency is more valuable than the raw handle size.

The next frontier is international expansion. MLB generates 10% to 15% of its total revenue from international markets, primarily through broadcasting and merchandise. As the betting infrastructure in those markets matures – particularly in the UK, where the regulatory environment is well-established – MLB’s share of international handle is poised to grow. UK bettors who develop expertise in baseball analytics now are positioning themselves in a market that is expanding rather than saturating.

Market Size FAQ

What share of total US sports betting handle goes to MLB?

MLB accounts for approximately 15% of total US sports betting handle, placing it behind football and basketball but ahead of hockey and soccer. That 15% translates to roughly $25 billion in annual MLB-specific handle, making it one of the deepest and most liquid betting markets in American sports. The daily game volume across a six-month season ensures consistent liquidity that other sports cannot match on a per-day basis.

How does MLB betting volume compare to football and basketball in the UK?

Football dominates UK sports betting by a wide margin, accounting for the majority of handle and GGY. Basketball and MLB both occupy smaller niches, but MLB’s availability on UK platforms has expanded significantly in recent years. Exact UK-specific handle figures for MLB are not publicly reported by the Gambling Commission, but the growing market depth on major platforms – including props, futures, and live betting – indicates rising demand among British punters for baseball coverage.
