The NFL is the most bet-on sport in the United States and one of the fastest-growing betting markets in the UK. In 2025, licensed US sportsbooks processed roughly $30 billion in NFL wagers—an 8.5% increase on the previous year—and the global sports betting market expanded from $119.26 billion to $125.12 billion, with projections reaching $325.71 billion by 2035 at a compound annual growth rate of 11.24%. These are not abstract figures for industry reports. They describe the market you bet into every Sunday, the liquidity that determines the odds you see, and the economic forces shaping how UK platforms structure their NFL offering.

This guide puts numbers to the NFL betting market from three angles: the US handle that drives global pricing, the UK demand that is reshaping how operators approach American football, and the live betting trend that is changing how the money flows.

US NFL Handle: Billion and Rising

The $30 billion in NFL handle through licensed US operators during the 2025 season represents the total amount wagered, not the amount lost. The distinction matters. US regulated sportsbooks processed $165.58 billion in total sports betting handle in 2025, generating $16.80 billion in gross gaming revenue at a hold rate of 10.15%. The NFL’s share—roughly 18% of total handle—makes it the single most valuable sport in American wagering.

FanDuel leads the US market with 39.6% of handle, followed by DraftKings at 35.3%. Together, those two operators control approximately 75% of the American sports betting market. The concentration matters for UK bettors because the pricing infrastructure that FanDuel and DraftKings build for the US market influences the odds you see on UKGC-licensed platforms, many of which use the same data feeds and pricing models adapted for fractional odds and British market conditions.

The growth trajectory has been steep. In 2019, before nationwide expansion of legal sports betting, total US sports handle was roughly $13 billion. By 2025, it had reached $165 billion. The NFL disproportionately benefited from this expansion because American football’s weekly structure—concentrated game windows, high-profile matchups, built-in narrative arcs—is ideally suited to the betting product. Every game matters, and the market treats it accordingly.

Super Bowl Handle: The Single-Event Record

The AGA projected $1.76 billion in legal wagers on Super Bowl LX—a figure that would set a new single-event record for any sport in the United States. Bill Miller, the AGA’s president and chief executive, described the Super Bowl as the event that brings fans together like no other, and the betting handle reflects that cultural gravity.

Super Bowl betting is unique because the two-week gap between the Conference Championships and the game itself creates an extended window for futures and pre-match wagers to accumulate. Handle builds gradually from the moment the two finalists are confirmed, accelerating through the final 48 hours before kickoff. The prop market for the Super Bowl alone generates hundreds of millions in handle, with novelty props (coin toss, anthem duration, Gatorade colour) attracting casual money that does not appear during the regular season.

For UK bettors, the Super Bowl handle figure matters because liquidity drives price accuracy. A market with $1.76 billion flowing through it produces tighter spreads, more competitive moneylines, and deeper prop coverage than a Week 4 game between two mid-table teams. If there is one NFL event where the odds on your UK platform most closely reflect the true probabilities, it is the Super Bowl.

UK NFL Demand: 14.3 Million Fans and Growing

The NFL counts 14.3 million fans in the UK—nearly one in five people in the country. Of those, 4 million are classified as “avid” fans who follow the league closely, watch games regularly, and engage with NFL content year-round. The numbers have grown steadily since the London Games became an annual fixture, and they position the NFL as the most popular American sport in Britain by a significant margin.

Monthly UK search volume for NFL-related content sits at approximately 1.2 million queries, which represents about 13% of the search volume generated by the Premier League. That ratio is far larger than most people expect—the Premier League is the most-followed domestic football league in the world, and the NFL has carved out a meaningful share of British sporting attention despite being a foreign import broadcast at awkward hours.

The team loyalty patterns in the UK are revealing. Kansas City leads UK search interest at 9.5%, followed by Philadelphia and San Francisco at 6.3% each. These preferences reflect recent on-field success and the London Games schedule, which disproportionately features teams the NFL believes will draw UK interest. The concentration of UK support around a handful of franchises means that betting volume on UK platforms skews toward games involving those teams, which in turn affects the odds available on those specific matchups.

Over 6 million UK viewers watched the 2025 London Games on television or online—a record for the international series. That viewership figure translates directly into betting activity, because the correlation between watching a sport and betting on it is well-documented. The 2026 schedule includes three London games plus additional international fixtures, and each one expands the window for UK-based NFL wagering.

Live Betting’s Share: 62% and Climbing

In-play betting accounted for 62.35% of global online betting revenue in 2025, and the format is growing at a compound annual rate of roughly 13.6%. The NFL, with its frequent stoppages, predictable game-flow patterns, and dramatic momentum shifts, is structurally well-suited to live wagering. Every change of possession, every scoring drive, and every injury timeout creates a new pricing point and a new opportunity for in-play bets.

For the UK market, live NFL betting faces a unique constraint: time zones. The majority of NFL games kick off between 6 PM and 1:30 AM UK time, which means the most active in-play window runs through the late evening and into the early morning hours. UK operators staff their NFL trading desks for these windows, but the depth of in-play markets available at 1 AM on a Monday is narrower than what you would find during a Premier League Saturday afternoon. The market exists and is growing, but it has not yet reached the saturation point seen in domestic football.

The growth of live betting also reshapes how pre-match odds are priced. When operators know that a significant percentage of handle will arrive during the game rather than before it, they can afford to run thinner margins on pre-match lines because the in-play market provides additional revenue opportunities. This benefits UK punters who bet pre-match, as the odds available before kickoff are marginally better than they would be in a market without a robust live-betting complement.

How does NFL betting volume compare to Premier League betting?
In the UK, the Premier League generates significantly more betting volume than the NFL. Monthly UK search interest in the NFL is roughly 13% of the Premier League"s volume. However, the NFL is the largest single-sport betting market in the United States by a wide margin, and its global handle dwarfs any individual football league. The comparison depends on geography: domestically in the UK, the Premier League dominates; globally, the NFL is the bigger betting product.
Is NFL the second-most bet sport in the UK?
Not by overall volume. Horse racing and football (soccer) both generate more betting handle in the UK than the NFL. However, the NFL is the most bet-on American sport in the UK and is growing faster than most domestic alternatives in percentage terms. Its concentrated season structure and the cultural momentum behind the London Games have driven consistent year-on-year growth in UK NFL betting volume.
