Five years after that explosive Series 6 finale left viewers demanding answers, Line of Duty is officially back in production. The bookies have already rolled out a proper spread of novelty markets on what fans can expect when AC-12 returns to screens.

A recent read-through confirmed Martin Compston, Vicky McClure and Adrian Dunbar are all reprising their roles, with Robert Carlyle joining as the series guest lead. Creator Jed Mercurio teased on social media that the trio may have “met their match” this time. That’s got everyone speculating about where the story goes next.

Filming kicks off in Belfast with a release window somewhere in late 2026 or early 2027. Long wait, granted. But it’s given the betting markets plenty of time to open up some genuinely interesting specials around potential storylines and outcomes.

Massive Viewing Figures Expected

The standout market has the Series 7 finale priced at 1/3 to pull in over 15 million UK viewers. That’s not just optimistic. It reflects the sheer cultural weight this show carries. Line of Duty consistently delivered some of the biggest telly audiences in recent years, and the extended gap since Series 6 has only ramped up the anticipation.

Entertainment betting expert Jake Ashton from OLBG noted that the markets reflect both the show’s massive popularity and its well-earned reputation for shocking twists. When a drama can command this kind of attention after a five-year break, you know it’s something special.

Robert Carlyle’s Character Already Drawing Action

The introduction of Carlyle has immediately shaped the betting. His character is priced at 3/1 to die during the series. Makes sense, really, given the show’s history of high-profile exits and brutal story arcs. New guest leads in Line of Duty rarely make it through unscathed, and punters clearly expect this series to follow form.

Meanwhile, the 2/1 on a main character being arrested suggests AC-12 could once again be investigating one of its own. That’s been a recurring theme throughout the run. It’s exactly the kind of internal conflict Mercurio loves to explore.

Fan Theories Drive the Specials

Several of the markets lean heavily into long-running fan theories and the show’s trademark narrative twists. Patricia Carmichael becoming the new AC-12 boss is priced at 3/1, while a character faking their death sits at 6/1. Both scenarios would be classic Line of Duty moves.

The most persistent fan theory gets its own market too. Ted Hastings being revealed as corrupt is offered at 10/1. That one’s been doing the rounds since Series 4, and while it feels unlikely, you can never completely rule anything out with this show.

What’s clear from these markets is that much of the betting is driven by narrative expectations rather than any inside information. The odds reflect what punters want to see happen as much as what they think will happen. Which is exactly how novelty markets should work when a beloved drama makes its long-awaited return.
