Grimsby Town Promotion Odds for 2025/26

Last updated: 11 August 2025 by Leon Marshall

From epic cup shocks to promotion charges that lit up Blundell Park, Grimsby Town’s history is rich with big moments and bigger memories.

The recent years, though, have tested even the most loyal Mariners, with setbacks and near-misses becoming part of the journey.

Yet there’s genuine optimism returning: Grimsby narrowly missed the play-offs last season, pushing the race to the final day and reminding supporters that this squad can compete at the sharp end of League Two.

With renewed energy on and off the pitch, many fans and bettors alike are eyeing another tilt at promotion. Football betting sites have priced up the League Two promotion market—and Grimsby are considered live outsiders.

Grimsby’s Latest Promotion Odds

The promotion odds below come from the mid-August market. MK Dons are the clear favourites, while Grimsby sit a little further back alongside other play-off hopefuls.

Grimsby Betting Markets Available

• To be promoted: around 7/2
• To win League Two: bookmakers offer anywhere from 12/1 to 20/1
• Top six finish: roughly 13/8 according to most sites (prices vary)
• Top scorer specials: options include Jaze Kabia and summer signing Justin Amaluzor, both trading at double-digit prices

Some firms also offer combined bets, promotion plus top scorer or “top two finish”. Check the terms carefully before placing a wager.

Grimsby Town 2025/26 Season Preview

Grimsby head into the new campaign buoyed by fresh leadership and a raft of new faces. David Artell has emphasised a high-pressing, front-foot approach. It paid immediate dividends as his side overran Crawley Town in the opener, with Kabia converting a penalty and McJannet heading home before Khouri completed the 3-0 win. That display set a benchmark for the season.

A week later Grimsby travelled to Harrogate. They trailed 3-1 with fifteen minutes left, but refused to accept defeat. Harvey Rodgers’ long-range strike narrowed the gap before substitute Kabia swept home an equaliser in added time. The comeback highlighted both depth and resilience—qualities often seen in promotion-chasing sides.

Artell’s summer rebuild focused on adding experience and versatility. The front line now features Kabia alongside Justin Amaluzor, who joined from Altrincham and is known for his pace and work ethic. In midfield, Jamie Walker offers creativity and leadership, while Zak Gilsenan adds technical craft. At the back, Jayden Sweeney, Sam Lavelle and Reece Staunton increase competition for places. Goalkeeper Christy Pym brings League One experience after his free transfer from Mansfield Town.

If the new signings settle in quickly and the team maintains the intensity shown in the opening fixtures, Grimsby could comfortably finish inside the top six. However, League Two is notoriously competitive; automatic promotion may require both consistency and a bit of luck.

Grimsby fans are focused on promotion, but their attention will also turn to the Carabao Cup, where they’ve been drawn against Manchester United in the second round. A victory against the Red Devils would certainly fill up those senses as it’s the first time the clubs have met in a cup since the 1940’s.

The Premier League club shouldn’t take the game lightly, as the Mighty Mariners have a reputation as giant killers.

In the 2023 FA Cup, Grimsby became the first team to defeat five higher-division clubs in a single campaign, reaching the quarter-finals.

And who could forget one of my biggest upsets of all time when Grimsby went to Anfield and beat the League Cup (Worthington Cup) holders Liverpool, thanks to a stunning Phil Jevons’ strike almost twenty-five years ago.

League Two Rivals

The promotion race in League Two looks fierce. MK Dons carry the shortest price at 5/6, with their attacking options and financial muscle putting them at the head of the market. Chesterfield, relegated from League One two seasons ago, are next best at around 6/5 and boast a balanced squad.

Walsall, Swindon and Bristol Rovers have all recruited heavily and sit between 10/3 and 15/4. Gillingham and Notts County are close behind at roughly 4/1. Grimsby’s opening fixtures against Harrogate and Crawley suggest they can compete with these sides, but tougher tests against the likes of MK Dons and Chesterfield will provide a more accurate gauge of their promotion credentials.

Verdict: Are Grimsby a Value Bet?

At 7/2, Grimsby sit in the second tier of promotion favourites. Their price reflects both a promising start and the competitive nature of League Two. Artell’s side has already shown attacking flair and resilience, and the summer signings improve depth. If Kabia continues to score and the midfield gel quickly, a play-off berth looks attainable.

Automatic promotion may require overtaking more fancied clubs such as MK Dons and Chesterfield, but for those seeking a mid-range punt, the Mariners offer reasonable value. It’s worth remembering that the Mariners only missed out on the play-offs on the last game of the season last campaign, so it wouldn’t be a total surprise to see them in the mix again.
