The London Games Effect on Betting Lines

Home-Field Gets Weird Fast

In a standard U.S. game, the market starts from an implicit home-field baseline (often discussed as roughly 2 to 3 points historically, though it varies by era).

In London, that baseline becomes a question: Is it truly neutral? Is one team "closer" in fan base? Is one team better at travel logistics? And most importantly, does the stadium environment play more like a bowl game (touristy, mixed crowd) than a hostile road spot?

Why London home-field is complicated:

• Standard U.S. game: 2 to 3 point home-field baseline
• London: truly neutral or one team closer in fan base?
• Travel logistics matter (one team better at it?)
• Stadium environment: bowl game or hostile road spot?

The NFL's own 2025 announcement shows how much "neutral" can still be asymmetric: the Vikings were scheduled to play in Dublin and then travel to London the following week (two consecutive international games), a spot that's fundamentally different from a one-off trip.

Two Consecutive International Games Create Unique Handicaps

That kind of schedule quirk creates a unique handicap: the second game may look "less disruptive" for the team that stays abroad, while the opponent is doing the classic one-week transatlantic jolt.

Two consecutive international games:

• Vikings: Dublin then London (stayed abroad)
• Second game less disruptive (already adjusted)
• Opponent: one-week transatlantic jolt (fresh disruption)
• Unique handicap that books must price

This is where sharp bettors can find edges. If the market doesn't fully adjust for "staying abroad vs fresh arrival," there's value on one side or the other.

Totals and Pace: The Market Still Isn't Fully Settled

If you want one data point that captures how uncertain London scoring can be, a betting trends breakdown reported that the under hit in 17 of 33 London games, and favorites were just 17-16 ATS in those games.

That's not a screaming "auto-under" or "auto-fade favorites" system. It's evidence that London behaves close enough to normal that you can't treat it like weather-in-a-blizzard, but different enough that totals and spreads can be mis-set in certain matchups.

London totals and spreads data:

• Under hit in 17 of 33 London games (51.5%)
• Favorites 17-16 ATS (51.5%)
• Not auto-under or auto-fade system
• Close enough to normal, but mis-set in certain matchups

There's also an important practical reason totals can be fragile: London games kick off at 9:30 a.m. ET (U.S. East Coast time), which creates unusual viewing and betting patterns in North America.

Early Kickoff Times Create Market Microstructure Effects

More early money, more "I want action" behavior, and often less time for late-breaking injury info to be processed by casual bettors.

Even if you don't believe in "body clock" effects, you should believe in "market microstructure" effects: standalone, early-window games can get priced differently because the money arrives differently.

Why 9:30 a.m. ET kickoffs matter:

• Unusual viewing and betting patterns in North America
• More early money, more "I want action" behavior
• Less time for late-breaking injury info to process
• Standalone early-window games priced differently

The sharpest London-related angle is often not the London game itself. It's what happens next week.

The "Week After London" Hangover Is Real

Action Network's analysis of teams playing after London without a bye week warned bettors to be extremely careful backing big favorites coming off that fast international turnaround.

The point isn't that teams "always lose" after London. It's that the travel plus compressed recovery can create flat starts and more variance, and the market sometimes still prices those teams like they're in a normal routine.

This matters for betting lines in two ways:

Books may shade against the "post-London" team (especially if the narrative becomes mainstream), which can create value on that team if the number moves too far.

Or books may not shade enough if the public is still buying the brand name, which can create value on the opponent, particularly as an underdog or in team totals.

Week after London angles:

• Travel plus compressed recovery creates flat starts
• Market sometimes prices teams like normal routine
• Books may shade against post-London team (value on that team)
• Or books may not shade enough (value on opponent)

How Line Movement Typically Plays Out

London weeks often have a distinct movement pattern:

The opener reflects pure power rating plus a neutral-site adjustment plus a best guess on travel impact.

The early-week market tests the number (especially if the favorite is a popular team).

Late-week movement is heavily influenced by injury reports and (most importantly) any clarity about travel schedules and whether a team treated the trip like a business trip or a mini-bye.

London line movement pattern:

• Opener: power rating plus neutral-site plus travel impact
• Early week: market tests number (especially popular favorites)
• Late week: injury reports, travel schedule clarity
• Business trip vs mini-bye matters

Because the NFL has expanded international scheduling (seven games in 2025, including London plus first-time or rare markets like Dublin and Madrid), books are increasingly forced to build "international priors" for teams.

The more international games exist, the more the market tries to learn which staffs handle travel well, which teams start slow abroad, and which offenses travel "cleanly" (snap count and tempo) versus those that depend on precise timing.

Props: Where the London Edge Often Hides

Spreads and totals are the most efficient markets. If there's a London edge, it often leaks into props:

Kicking and punting props can be sensitive to stadium sightlines and surface familiarity.

Player usage props (rush attempts, target share) can shift if the game starts sloppy and coordinators lean conservative early.

"First quarter" and "first half" markets can be more sensitive to sluggish starts than full-game markets, because a team can start slow and still win.

Where London edges hide:

• Kicking and punting props (sightlines, surface familiarity)
• Player usage props (sloppy start, conservative coordinators)
• First quarter and first half markets (sluggish starts)
• Full-game markets less sensitive (team can start slow, still win)

The most actionable London takeaway: treat international games as neutral-site plus travel-variance events, not as "weird football." Use them to demand better prices, especially on totals and short favorites, and be even more intentional about the week-after-London spot (bye vs no bye).

The Bottom Line on London Games

NFL London games change betting lines by breaking home-field assumptions (2 to 3 point baseline becomes question mark) and body-clock routines. 2025 featured seven international games, most ever. Home-field gets weird: truly neutral or one team closer? Travel logistics matter. Vikings played Dublin then London (two consecutive international games), second game less disruptive for team staying abroad. Treat London as neutral-site plus travel-variance events, demand better prices on totals and short favorites, be intentional about week-after-London spot (bye vs no bye).
