Premier League Unbeaten Season Odds (2025/26)

The Premier League season has produced many memorable title races, but only one team has ever finished a season without a single defeat. In 2003‑04 Arsenal went 26–12-0, collecting 26 wins and 12 draws to win the title and earn the “Invincibles” nickname.

Their unbeaten run stretched to 49 top‑flight matches across three seasons, still the longest in Premier League history. Since then, only Liverpool (44 matches between January 2019 and February 2020) and Chelsea (40 matches from October 2004 to October 2005) have come close.

With the new season starting on the 15th August 2025, attention now turns to which side, if any, can match the “Invincibles”.

Have a look at our round up of the latest and the best odds for pulling it off below:

66/1 with Ladbrokes

Instead of resting on their laurels, the defending champions have sent a clear message of intent by spending big to sign Florian Wirtz, Hugo Ekitike, and Jeremie Frimpong.

This aggressive move to strengthen from a position of power is precisely why the bookies have installed them as the clear 66/1 favourites to complete a historic unbeaten season.

125/1 with Betfair

As the only club to go a whole Premier League season unbeaten (2003-04), Arsenal have already strengthened their attack by signing striker Viktor Gyökeres.

With the Gunners still linked to creative reinforcements like Eberechi Eze after their second-place finish, a title push is clearly the target. However, at 125/1, repeating their 'Invincibles' season remains a tall order.

125/1 with Betfair

While Pep Guardiola’s side are capable of immense consistency, proven by their 32-match unbeaten run between Dec 2023 and Nov 2024, last season was uncharacteristically fragile.

The team lost nine league games and ended the campaign trophy-less, exposing a vulnerability not seen in previous years.

While a response is expected, rebuilding that aura of invincibility makes a flawless unbeaten season a significant challenge.

150/1 with Paddy Power

Chelsea's recent triumph in the Club World Cup shows they are a club on the rise under Enzo Maresca.

However, translating that knockout success on the world stage into the relentless consistency required for a 38-game unbeaten league season is a monumental leap.

The bookmakers' odds of 150/1 reflect this reality, underscoring just how remote the prospect of an 'Invincible' campaign is for the Blues.

Building on their title-winning campaign, new manager Arne Slot has wasted no time in strengthening key areas of the pitch.

This significant summer investment, coupled with ongoing interest in proven goalscorers like Alexander Isak, signals a clear strategy to dominate the league.

While the 66/1 odds confirm the difficulty of the feat, this proactive recruitment makes Liverpool the standout candidates to challenge history.

For Arsenal, repeating history is the ultimate challenge. They have already moved to sharpen their attack by signing striker Viktor Gyökeres, addressing a key issue from last season: a lack of ruthlessness in turning draws into wins.

With reports linking them to further creative reinforcements like Eberechi Eze, the intent is clear.

However, the weight of their own 'Invincibles' legacy creates immense pressure, and their 125/1 odds underscore just how monumental the feat of a second perfect season would be.

The dilemma for Manchester City is clear: their 32-match unbeaten run from December 2023 to November 2024 proves they possess the quality for a perfect season, yet the nine league defeats they suffered in a trophy-less 2024-25 highlight a new-found inconsistency.

Last season exposed a worrying fragility when key players were absent, shattering their previous aura of dominance. This is why their prospects are viewed as similar to Arsenal's.

Both teams have proven quality but must overcome a significant final hurdle to achieve perfection, a challenge reflected in their identical 125/1 odds.

Chelsea's recent Club World Cup win shows they are capable of securing silverware again.

The bookmakers reflect this, pricing them at just 5/2 with Betfair to win any major trophy in 2025-26. A domestic double is seen as a bigger challenge at 90/1.

However, the immense gulf between being a cup-winning side and a perfect league team is shown by their 150/1 odds for an unbeaten season, putting the scale of the task into sharp perspective.
