Americans legally wagered $166.94 billion on sport in 2025. I have been tracking this market since it was a fraction of that size, and even I find the velocity difficult to process. For context, that figure exceeds the annual revenue of Netflix, Nike, and Coca-Cola combined. It grew 11% year-on-year, in a market that is barely seven years old. And it forms the financial backdrop against which the NBA’s gambling scandal must be understood — because the size of this market is not incidental to the scandal. It is the reason the scandal was possible.

This is not a story about gambling as a vice. It is a story about gambling as an industry — one that generates record revenue, record tax receipts, and record integrity risks in roughly equal measure.

Handle and Revenue: Understanding the Core Numbers

Two numbers define the US sports betting market, and they are often confused. The first is handle — the total amount wagered. At $166.94 billion in 2025, that figure represents every dollar placed on every legal sportsbook in the country, win or lose. The second is revenue — the amount sportsbooks actually keep after paying out winning bets. That figure hit $16.96 billion in 2025, a 22.8% increase over the previous year.

The relationship between handle and revenue is captured by the hold rate — the percentage of wagers that operators retain. The average US sportsbook hold rate reached 10.15% in 2025, which is significantly higher than the traditional benchmark of 5-7% that prevailed in Nevada’s mature market. Why the difference? Two factors. First, the proliferation of parlay bets and same-game parlays, which carry much higher margins for the house. Second, the growth of prop bet markets, where pricing inefficiencies — and the informational advantages that insiders can exploit — inflate operator margins.

For a UK audience accustomed to thinking in terms of gross gambling yield, the comparison is instructive. British bookmakers typically operate at lower margins than their American counterparts, in part because the UK market is mature and competitive, and in part because the Gambling Commission imposes transparency requirements that American state regulators do not. The higher US hold rate is not simply a sign of superior operator performance — it reflects a market where consumer protections are less developed and where information asymmetries are more easily monetised.

The revenue growth rate — 22.8% — is the number that should concern integrity analysts most. Revenue is growing faster than handle, which means operators are extracting a larger share of each wagered dollar. That extraction comes disproportionately from products like player props and parlays, the very markets most vulnerable to manipulation. The incentive structure is circular: operators promote high-margin products because they are profitable, those products attract integrity risks because they are exploitable, and the resulting scandals threaten the market that generates the revenue.

From $0 to $600 Billion: The Post-PASPA Growth Curve

In May 2018, the US Supreme Court struck down the Professional and Amateur Sports Protection Act, and legal sports betting outside Nevada effectively did not exist. Since that decision, the cumulative legal handle has exceeded $600 billion. That is $600 billion in less than eight years, in a product category that was functionally illegal for most of the preceding quarter-century.

The growth curve followed a predictable but still remarkable trajectory. New Jersey moved first, launching legal sportsbooks within weeks of the ruling. Pennsylvania, Indiana, and Colorado followed in rapid succession. By 2026, 38 states and the District of Columbia had legalised some form of sports betting, creating a coast-to-coast market that only a handful of holdout states — California, Texas, and a few others — have not yet joined.

Each new state launch produced a spike in national handle, as pent-up demand was released into legal channels. But the growth has not been driven solely by geographic expansion. Per-capita wagering in mature markets has continued to increase, driven by mobile betting apps, live in-play wagering, and the relentless expansion of available markets. A bettor in New Jersey or Pennsylvania today has access to thousands of betting options on a single NBA game — from traditional point spreads to player props to same-game parlays to live quarter-by-quarter lines. The market’s depth, not just its breadth, is what makes it unprecedented.

Live Betting’s Dominance: 62% of the Online Market

Here is a number that does not get enough attention: in-play betting — wagers placed after a game has started — accounted for 62.35% of the US online sports betting market in 2025. That means nearly two-thirds of all online dollars wagered were placed in real time, while events were unfolding on the court or field.

The growth of live betting has profound implications for integrity. Pre-match betting offers a relatively stable environment for monitoring: odds are set, markets open, and any suspicious movement can be analysed before the event begins. Live betting is fundamentally different. Odds change continuously, markets open and close within minutes, and the volume of data generated is enormous. Monitoring systems designed for pre-match environments struggle to keep pace with the speed and complexity of in-play markets.

For manipulators, live betting offers opportunities that pre-match markets do not. A player who knows he will sit out the second half of a game — because he has been told by the coaching staff, or because he has agreed to limit his minutes — can relay that information to an associate who places live bets on “under” lines for that player’s statistical performance, with the odds still reflecting full-game expectations. The bet is placed, the player exits, the “under” hits, and the payout arrives. The entire cycle can occur within a single quarter of basketball.

The tax revenue generated by live betting is substantial, which gives state regulators a financial incentive to keep these markets robust. The integrity risks those markets create receive far less institutional attention than the revenue they produce — a dynamic that integrity analysts, myself included, find deeply troubling.

What a $167 Billion Market Means for Match-Fixing Risks

Scale changes everything. A $10 billion market attracts hustlers. A $167 billion market attracts organised crime.

The IBIA recorded 300 suspicious betting alerts globally in 2025, a 29% increase over the previous year. That figure covers all sports, not just basketball, but the trend line is unambiguous: as legal betting markets grow, the incentive for manipulation grows with them. More money flowing through legal channels means more money available to be exploited, and the returns on successful manipulation scale proportionally.

The NBA scandal illustrated this dynamic precisely. The sums involved in the Rozier and Porter cases were not trivial — $263,000 in suspicious props wagering in a single game, an $80,000 parlay with a potential payout of $1.1 million — but they were modest relative to the total market. The scandal’s significance lies not in the dollar amounts but in what it revealed about the market’s structural vulnerabilities: that insider information retains enormous value in a market of this size, that monitoring systems cannot track every transaction, and that the financial infrastructure for exploitation — both legal and illegal — is readily available.

For anyone watching the US market from Britain, where regulated sports betting has a longer history and a more mature oversight framework, the American experience offers a cautionary lesson. Rapid market growth without commensurate investment in integrity infrastructure creates a gap that bad actors will exploit. The US is learning that lesson at scale, and the tuition is being paid by the sports and the fans who trusted them to police themselves.
