Big Brother Odds 2025

Cameron Kinch was the early favourite to win this year's Big Brother. He was the clear favourite on new betting sites, but any of the other housemates could win it. With weeks ahead of us, there's sure to be plenty of change in the betting as housemates are evicted and potentially added. You'll find the latest Big Brother odds right here on Bookies.com.

Other Big Brother Betting Markets

In the past, UK betting sites have offered odds on additional Big Brother betting markets, like next eviction, top male and top female. With this season of Big Brother expected to last until some time in mid-November, and a lot of housemates to evict before we reach the final, it’s unlikely there’ll be many betting markets available beyond the odds to win Big Brother.

Who Will Win Big Brother 2025?

While first impressions are big, it often pays to oppose the early favourites to win Big Brother. At this stage, you're usually looking for someone prominent in the betting but not right at the top. We'll have a better idea of who will win as the series progresses. Be sure to check back for our Big Brother 2025 betting tips.
