NFL London Betting — How International Games Affect the Lines
Available in US
The Only NFL Games You Can Walk To
More than six million people watched the 2025 London games on television or online — a record for NFL’s international push that shattered every previous benchmark. Since 2007, the International Series has staged 36-plus regular-season games in the UK, drawing a combined attendance of over 2.2 million fans through the turnstiles. For UK bettors, these games are not just a novelty. They are the one slice of the NFL calendar where you hold a genuine informational and contextual edge over the broader market.
I attended my first Wembley NFL game in 2014 and have been to every London fixture since. Watching games in person, seeing how teams adapt (or fail to adapt) to the venue, the crowd, and the transatlantic schedule, has shaped how I bet these matchups. The factors that move London lines are different from those in a standard Week 7 game in Kansas City, and recognising that difference is where the edge lives.
Travel, Jet Lag, and the Five-Hour Shift
Entain reported that betting volume on NFL London games grew 51% year on year in 2024 compared to 2023, which tells you UK punters are paying attention. But how many of them are factoring in the physiological reality of what those teams just went through?
An NFL team flying from the US West Coast to London crosses eight time zones. Even East Coast teams face a five-hour shift, and most arrive only a few days before kickoff. Sleep science consistently shows that the body adjusts to time-zone changes at a rate of roughly one hour per day. A team that lands on Wednesday and plays on Sunday has, at best, partially adapted.
This does not always manifest as poor play — adrenaline and professional conditioning mask a lot — but it does show up in specific ways that affect betting lines. Late-game fatigue becomes more pronounced. Decision-making in the fourth quarter can deteriorate, particularly for teams that did not arrive early. Teams that travel a week in advance and build the London trip into their bye week historically perform better than those that treat it as a standard road game with a longer flight.
My approach: I track which teams arrive early, which hold practice sessions at the game venue versus a nearby training facility, and whether the coaching staff has any prior London game experience. These soft factors rarely appear in statistical models but consistently correlate with performance against the number.
Neutral Venue Dynamics
Every NFL London game is technically a home game for one team, but the reality is that neither side has a true home advantage. Tottenham Hotspur Stadium and Wembley are magnificent venues, yet the crowd is largely neutral — a mix of fans from both teams, UK-based supporters of neither, and casual spectators experiencing the NFL for the first time. The standard 2.5 to 3-point home-field advantage built into NFL spreads does not apply in the same way.
Sportsbooks have learned this over the years and typically reduce the home-field adjustment for London games, but the correction is not always precise. In some seasons I have seen the “home” team in London priced as if they had a full home-field edge, which inflates the spread by a point or more compared to a true neutral-site line. That extra point is a gift for anyone betting the “away” side.
The atmosphere itself plays a role too. NFL crowds in American stadiums produce directional noise — they go silent on offence and roar on defence. London crowds cheer everything. A long reception for either team gets the same response. This levels the playing field in ways that the data-only bettor misses, but that anyone who has been to a London game recognises immediately.
Historical ATS Performance in London
The editorial team at London Loves Business described the 2025 overseas games as having “broken every record the NFL had set for its international push”. That growth has also generated enough data to start identifying patterns in how London games settle against the spread.
Over the full sample of International Series games, no single trend dominates. Favourites have covered at a rate close to the league average, and there is no statistically significant lean toward overs or unders. What does stand out is variance. London games produce more unexpected results — larger deviations from the closing spread — than the average regular-season game. This makes sense: when two teams are displaced from their routine, operating in an unfamiliar environment on disrupted body clocks, outcomes become less predictable.
Higher variance is not a reason to avoid betting London games. It is a reason to bet them differently. I size my London bets at roughly half my standard unit, because the expected range of outcomes is wider. If you have a strong view, you can still express it — just do not pretend the game carries the same level of predictability as a home divisional matchup in Week 14.
One pattern I have noticed, though the sample is small enough to warrant caution: teams making their second or third London appearance tend to handle the logistics better than first-timers. The Jacksonville Jaguars, who played annually in London for years, consistently performed closer to expectations than teams making their debut. Familiarity with the venue, the travel, and the schedule seems to compress variance.
Betting London Games from the UK
The practical advantage UK punters hold for London games is access to real-time local information. You know the weather at the venue before the sportsbook’s algorithm adjusts the total. You can attend the open practice sessions that some teams hold in the days before the game, giving you a first-hand look at player movement and energy levels. You can gauge the crowd composition at the stadium and form a view on whether the “home” side will receive any meaningful support.
None of this is insider information — it is publicly available context that most of the betting market, dominated by US-based sharp money, simply does not prioritise. The American sharps are focused on DVOA matchups and snap-count data. You are standing outside the team hotel at 7am watching which players are limping to the bus. Both approaches have value; combining them is where the real edge sits.
London games are a small sample — typically three to five per season — so they will not define your annual results. But they are the one corner of the NFL calendar where being a UK-based bettor is an unqualified advantage rather than a geographical inconvenience. Use it.
Do NFL teams playing in London historically cover the spread?
Over the full sample of International Series games, there is no strong trend favouring either favourites or underdogs against the spread. What the data does show is higher variance — London games produce more unexpected outcomes than the average regular-season fixture, likely due to travel disruption, neutral-venue dynamics, and unfamiliarity with the environment.
How does jet lag affect NFL betting lines for London games?
Jet lag primarily impacts late-game performance and fourth-quarter decision-making, particularly for West Coast teams crossing eight time zones. Sportsbooks adjust their lines somewhat for the London context, but the correction is not always precise. Bettors who track which teams arrive early, which have prior London experience, and how coaching staffs prepare for the time shift can identify mispriced lines.
