  • Pauline Adeyemo is the early favourite at 6/4 (40.0% implied probability), just ahead of Millie Jarrett and Charlotte Nott, who share second favouritism at 2/1 (33.3%).

Housemates Enter As Betting Experts Open Winner Market

The betting experts have wasted no time getting a market for this year's Big Brother UK winner after contestants entered the famous house last night, with all 15 housemates now settling in for what promises to be another eventful series. 

It's always one of the more unpredictable entertainment markets of the year, and with the full line-up finally revealed, punters have plenty to weigh up before a single eviction has taken place.

Pauline Adeyemo has emerged as the early favourite among the experts, while the launch itself came with a big twist. 

Ahead of the series, ITV live-streamed a "dry run" featuring a group of social media influencers spending 24 hours in the house, and on launch night it was revealed that one of them, Michael "Tays" Taylor, would remain behind as a hidden "mole," kicking the first week off under the "House of Chaos" theme.

How The Mole Twist Could Shake Things Up

The "House of Chaos" mole twist adds an extra layer of intrigue before the series has even settled into its usual rhythm. 

With Michael "Tays" Taylor remaining in the house undetected by his fellow contestants, the opening week looks set to be shaped as much by suspicion and shifting alliances as by any of the usual early housemate dynamics.

Tays will choose a housemate to become a mole alongside him, before placing three people up for eviction this week.

What the expert says...
Pauline Adeyemo heading the market on day one always feels like a bit of a leap of faith from the experts, but first impressions clearly count for something in this game. The mole twist is the real wildcard here though, as Tays could choose anyone for eviction this week.
