Numbers have a way of settling arguments. When someone tells me that baseball betting is a niche within a niche, I point to the market size and the conversation changes. MLB generated a record $12.1 billion in revenue in 2024, the US sports betting handle surpassed $165 billion in 2025, and crypto casinos now account for roughly 17% of all global iGaming wagers. The MLB betting market size is not a rounding error — it is a multi-billion-dollar ecosystem, and crypto’s share of it is growing fast enough to reshape how the entire industry operates.
This article puts the MLB betting market in context: its place within the broader US sports betting handle, its weight in the global online gambling revenue picture, the portion flowing through bitcoin and other cryptocurrencies, and the seasonal patterns that make baseball uniquely important during the summer months.
Global Market Data: MLB Betting Handle and Revenue Share
I remember when the US sports betting market was a concept rather than a reality. Since the Supreme Court struck down PASPA in 2018, more than $600 billion has been wagered legally across American sportsbooks. The 2025 figure alone — exceeding $165 billion — represents a market that has grown faster than almost any other consumer sector in the country.
MLB’s share of that handle is smaller than the NFL’s or the NBA’s in absolute terms, but its structure gives it outsized importance on a per-day basis. The NFL offers 272 regular-season games across eighteen weeks. MLB offers 2,430 regular-season games across twenty-six weeks. That daily volume — fifteen games on a typical weeknight, with a full slate of day games on weekends — generates consistent handle that fills the calendar gaps left by other sports.
State-level tax revenues from sports betting rose 382% between the third quarter of 2021 and the second quarter of 2025. That fiscal windfall has cemented sports betting’s place in the American regulatory landscape and ensured continued market expansion. For UK bettors, the US market’s growth matters because it drives investment in the odds-modelling infrastructure that crypto sportsbooks licence for their own MLB lines. A bigger US market means sharper lines, deeper props and better-priced futures on the platforms British bettors use.
The handle number tells only part of the story. The average hold percentage — what the sportsbook retains from total wagers — stood at 10.15% in 2025 for US books. At that rate, $165 billion in handle produces roughly $16.7 billion in gross gaming revenue. MLB’s contribution to that figure is proportionally weighted toward the summer months, when baseball is the dominant sport on the betting calendar.
MLB Within the Global Online Gambling Revenue Picture
The global online gambling market crossed $121 billion in revenue in 2025 and is on track to reach $123 billion by the end of 2026. Sports betting accounts for 52% of that total — approximately $63 billion — with casino, poker and lottery splitting the remainder. MLB sits within the sports betting segment, competing for share with football, basketball, tennis and cricket across different time zones and seasonal windows.
The broader gambling market’s trajectory is upward, with projections of $369 billion in growth at an 8.2% compound annual rate through 2030. That expansion is driven by legalisation, mobile adoption and payment innovation — the same forces propelling crypto’s integration into sports betting. The platforms that serve UK baseball bettors today are riding a global wave that shows no signs of cresting.
What makes MLB interesting within this global picture is its data density. Baseball generates more trackable statistics per game than any other major sport, which creates richer betting markets. A single MLB game can produce forty or more individual prop markets, compared with ten to fifteen for a typical football match. That granularity attracts a specific type of bettor — analytically inclined, willing to do research, and drawn to markets where information asymmetry creates value. The demographic profile of the crypto baseball bettor aligns closely with this description.
The Crypto Share: How Much Baseball Wagering Flows Through Bitcoin
Quantifying crypto’s exact share of MLB betting handle is difficult because offshore platforms do not report to regulators. But the available data points paint a clear picture. Crypto casinos generated $81 billion in annual revenue in 2025 — a fivefold increase from $16 billion in 2022. Within that total, sports betting is a significant vertical, and baseball benefits from the same crypto adoption trends driving the broader market.
Bitcoin dominates crypto gambling with approximately 66% of all volume. Ethereum accounts for 9%, Litecoin 6%, and stablecoins like USDT make up a growing share that industry projections place above 70% of crypto wagering transactions by 2026. For MLB specifically, the crypto share is concentrated among bettors who value speed (Lightning Network deposits for live betting), privacy (no-KYC access to markets unavailable on UK-licensed platforms) and the broader market depth that offshore crypto sportsbooks offer.
The trajectory suggests that crypto’s share of total sports betting handle will continue growing, driven by younger demographics entering the market, stablecoin adoption reducing the volatility barrier, and Lightning Network infrastructure making crypto deposits as frictionless as card payments. Whether that growth happens within a regulated framework or continues to flow through offshore channels depends largely on decisions that the UKGC and its international counterparts have yet to make.
Summer Seasonality: When Baseball Dominates the Betting Calendar
Every summer, something interesting happens in the sports betting world: baseball becomes the biggest game in town. The NFL and college football are dormant. The NBA and NHL seasons are over. The Premier League is in its off-season. From mid-June through early September, MLB is the only major North American sport with daily action, and the betting handle reflects that monopoly.
Sportsbook revenue data consistently shows a summer dip in overall handle driven by the absence of football, but the MLB-specific handle actually increases as bettors who normally spread their action across multiple sports concentrate it on baseball. This seasonal shift creates deeper markets and tighter lines during the summer months, which is good news for bettors who have the analytical tools to exploit them.
For crypto baseball bettors, summer seasonality has a practical implication: the months from June through August represent the prime window for MLB wagering. Prop markets are at their deepest, line movement is most predictable, and the volume of games creates a statistical laboratory where disciplined approaches can generate consistent returns. The World Series may be the marquee event, but the long summer grind is where bankrolls are built.
