I break betting odds news as it happens, so you’re never left behind when the market moves or a top offer lands.
- Jenny Baird remains 2/1 favourite to win Big Brother 2025.
- Zelah Glasson and Richard Storry continue to sit just behind in the market.
- Sam, Emily, and Farida re-entered via a secret house twist on Friday.
There’s been no major shift in the Big Brother 2025 winner betting odds this week, with Jenny Baird holding firm at the top of the market as 2/1 favourite to be crowned champion.
But a new twist in the show could shake things up, with evicted housemate Sam making a dramatic return via a secret house twist.
The surprise return, revealed during Friday night’s episode, saw Emily, Farida (from 2023's series) and Sam enter a secret house and with viewers now speculating on how the twist will impact public voting and house dynamics, the betting sites may soon see movement in the odds.
William Hill's market keeps Jenny as leader with a 33.3% chance of winning the show this year.
Latest Big Brother 2025 Winner Odds
| Big Brother 2025 Winner | Odds | Implied Probability |
|---|---|---|
| Jenny Baird | 2/1 | 33.3% |
| Zelah Glasson | 7/2 | 22.2% |
| Richard Storry | 4/1 | 20.0% |
| Cameron Kinch | 5/1 | 16.7% |
| Elsa Rae | 20/1 | 4.8% |
| Caroline Monk | 25/1 | 3.8% |
| Emily Hewertson | 25/1 | 3.8% |
| Farida Khalifa | 25/1 | 3.8% |
| Sam Ashby | 25/1 | 3.8% |
While Jenny continues to set the pace, Zelah Glasson has quietly built a loyal fanbase and sits at 7/2 just ahead of the well-liked Richard Storry at 4/1.
Cameron Kinch, a social media favourite, still holds outsider potential at 5/1.
What Does the Secret House Twist Mean for the Market?
The reintroduction of three evicted contestants via a secret house adds an unpredictable layer to this year’s series.
Sam, who was a polarising figure during his first stint, could either reignite his popularity or stir up conflict, both scenarios that could impact the betting odds significantly.
Public reaction to the twist will be crucial, especially if viewers feel former housemates deserve a second chance, or if tensions rise with the current crop.
Betting sites like William Hill will be watching closely for any shift in sentiment across social media and vote patterns.
