I was at London Stadium for the 2023 London Series — Cardinals versus Cubs — squeezed between a bloke in a vintage Ernie Banks jersey and a woman who had never watched a baseball game in her life. By the third inning she was asking me about run lines. That is the London Series in a nutshell: it turns curious Brits into baseball fans at an extraordinary rate, and a fair number of those new fans find their way to a betting slip within weeks.
The numbers back this up. Roughly 71% of the 55,000 attendees at the 2023 London Series were UK citizens — not American expats, not tourists, but locals who chose to spend a Saturday at the baseball. Merchandise sales for MLB in Britain jumped 43% after that series, and UK-based MLB social media channels saw follower growth of 133%. Graham Gilmore, CEO of London Stadium, has pointed to the continued growth of MLB in the UK and Europe as evidence of the lasting impact these events create.
For bettors, the London Series presents a unique set of circumstances: a neutral venue, unusual scheduling, heightened public interest and bookmaker markets that may not fully account for the quirks of transatlantic baseball. This guide covers the context, the betting markets and the angles that matter when MLB crosses the Atlantic.
The London Series in Context: Why It Matters for UK Baseball Betting
MLB’s London ambitions started well before the first pitch at London Stadium. Kelhem Salter, MLB’s Director of Growth and Strategy for EMEA, has described Europe as a key growth market and Londoners as enthusiastic event-goers who consistently sell out international fixtures. The league backed that assessment with action: London has hosted regular-season MLB games annually since 2023, with the 2024 series contributing to a year in which international MLB viewership rose 18% thanks to games in Korea, Mexico and London.
The economic footprint is substantial. MLB’s London games were among the events that contributed to an estimated two hundred and thirty million pounds in economic impact for the city in 2024, alongside the NFL International Series and the London Athletics Meet. Stephanie Peacock, UK Minister for Sport, cited the MLB London Series specifically as part of a “fantastic year for London hosting major sporting events” that inspires the next generation.
For bettors, this context matters because it explains why bookmaker coverage of the London Series is disproportionately deep compared to a standard regular-season game. The event attracts media attention, casual betting volume and promotional activity from operators eager to ride the wave of public interest. That promotional activity sometimes creates pricing inefficiencies — more on that in the markets section below.
Around 4,500 young Londoners were also engaged in baseball and softball through the First Pitch programme tied to the 2024 London Series, building a grassroots pipeline that ensures the audience for these games — and the betting interest that follows — will only grow in the years ahead.
Betting Markets Available for the London Series
When the London Series is on the schedule, UK bookmakers roll out the full suite of MLB markets plus a few extras you would not normally see on a mid-week regular-season game. The standard menu includes moneyline, run line, game totals, first five innings markets, player props (strikeout totals, home runs, total bases) and futures implications for the participating teams.
What distinguishes the London Series from a normal MLB game is the depth of secondary markets. Because public interest is high and betting volume spikes, bookmakers are willing to price niche markets that might not appear for, say, a Tuesday game between Kansas City and Oakland. You might see inning-by-inning betting, correct score markets, first home run scorer, both teams to score in a specific inning and novelty markets tied to the event itself.
Enhanced odds promotions are common around the London Series. Operators use the event as an acquisition tool — a hook to bring new MLB bettors onto their platform. These promotions are worth evaluating on their own terms, but do not let a flashy enhanced price pull you away from a bet you have actually analysed. A boosted moneyline at 6.00 on a team you have no opinion about is not value; it is marketing.
Live betting is particularly interesting during the London Series because the games take place during UK daytime hours — typically a 6 PM or 7 PM local start. This is a massive advantage over standard MLB scheduling, where most games begin at 11 PM or later UK time. You can watch the game live, follow the in-play market in real time and make decisions without setting a 3 AM alarm. If there is one time of year to try MLB live betting, the London Series is it.
How Neutral-Venue Odds Differ from Standard Home/Away Pricing
Home advantage in MLB is real but modest — roughly 54% win rate for home teams across the league historically. The London Series eliminates this factor entirely. Neither team is playing at their home ballpark. Both teams have travelled across the Atlantic. Both are adjusting to jet lag, an unfamiliar playing surface and a crowd that cheers differently to what they are used to.
Bookmakers handle this by compressing the line. In a standard regular-season game, the home team gets a small boost in the pricing. In a London Series game, that boost disappears. The result is that the two teams are priced almost entirely on roster quality and pitching matchup, with very little baked in for venue advantage. This sounds straightforward, but it creates a subtle mispricing opportunity.
London Stadium’s outfield dimensions and playing surface are configured specifically for baseball during the series, but they do not perfectly replicate any MLB park. The outfield walls, the turf, the sight lines for batters — all are slightly unfamiliar to both teams. In my experience, this neutral-venue uncertainty tends to suppress scoring slightly compared to what the same pitching matchup would produce at a standard MLB park. If you believe the same, totals markets on London Series games may offer Under value that the bookmaker has not fully priced in.
Choosing a Bookmaker for London Series Action
During the London Series, nearly every major UKGC-licensed bookmaker offers MLB markets — some for the first time all year. The question is not availability but quality: which operators price the London games competitively, settle bets promptly and offer the market depth that makes the event worth betting on?
Look for bookmakers that carry a full MLB product year-round rather than those that only surface baseball during the London Series. Year-round operators have established pricing models, experienced traders and reliable settlement procedures for baseball. Operators who parachute in for the London Series may offer flashy promotions but can have clunky settlement or thin live betting menus.
Compare moneyline prices across at least three operators before placing your London Series bets. The public attention means recreational money is flowing in, which can distort prices at operators with less sophisticated risk management. A two-minute odds comparison can gain you 0.10 to 0.15 on the decimal price, which compounds meaningfully if you are placing multiple bets across the series.
