Important: if you don’t see odds on Big Brother Season 27 when you visit the bookmaker, that’s usually because the show is currently running or there was an episode in the previous 12-24 hours. The oddsmakers usually need a day to process the events and update their Big Brother odds of winning after each episode.
Additionally, since the show is broadcast on a live feed, a major event could pull the prices off the board momentarily.
Zach Cornell (+300) remains the betting favorite to win Big Brother Season 27. However, Zach’s odds have regressed from last week’s episodes. Heading into the fourth week of the competition, Zach had a +150 price, or 40% implied probability at Big Brother betting sites.
Currently, Zach’s betting odds to win Big Brother 27 have decreased to 25% at +300 odds. That’s a pretty substantial dip, but oddsmakers still have him marked as the favorite. Zach is followed by Vince Panaro (+400), who has seen his odds cut in half from +800 to +400 in a week.
Ava Pearl (+450) has been the biggest mover, as her Big Brother winner odds have skyrocketed nearly to the top in one week! Last week, Ava had the longest price on the board at +1600! Now, you can bet on her to win at +450, with the third-best odds to win the game.
In other words, Ava’s implied chance has improved from 5.9% to 18.2%. The biggest takeaway from the line movement over the last week is that the online bookies don’t have much confidence in who is going to win, so there is great value up for grabs!

Big Brother Season 27 Latest Episode Recap and Updated Betting Pick
As is customary with Big Brother betting odds, the prices can move drastically in a short period of time. Due to Big Brother being broadcast live, in addition to episodes on CBS, this is common and essentially one long in-game wagering event.
So, again, I recommend targeting the best value. The insane line movement over the last week showcases how things can change at the drop of a hat in the Big Brother house. With this in mind, if you like a houseguest to win, then I recommend sticking with that pick.
In the latest episode, Ava won Head of Household and was finally able to wield some power in the game. She put Keanu Soto, Vince Parano, and Ashley Hollis. Keanu has been a regular target in this game and has won the Power of Veto to remove himself from the block.

Is Keanu going to continue to dominate in POV competitions? He will probably need to if he’s going to stay in the game. Oddsmakers aren’t convinced that Vince is going home because he still has the second-best Big Brother betting odds.
For my updated Big Brother winner pick, I’m still looking at Morgan Pope to win at +800. Although she has irked a few people in the house, Morgan remains largely a floater who, I believe, isn’t showing all of her cards yet. The Twitch streamer may not have any competition wins, but she is playing the social game well and should break through in competitions.
She is playing a strong enough game at the moment that I believe +800 odds is a massive bargain!
Big Brother Season 27 Houseguests
Big Brother 27 features 16 contestants coming together to live in isolation from the outside world in the Big Brother House!
Airing weekly on Sundays and Thursdays on CBS at 8-9:30 p.m. ET, they will go through a series of challenges while fine-tuning their social game to avoid elimination.
Let’s learn about the entire group of houseguests that are competing on the 27th season of Big Brother:
-
- Adrian Rocha, 23, carpenter (San Antonio, TX)
- Amy Bingham, 43, insurance agent (Stockholm, CA)
- Ashley Hollis, 25, attorney (Chicago, ILL)
- Ava Pearl, 24, aura painter (Long Island, NY)
- Clifton “Will” Williams, 50, college sports podcaster (Wallace, SC)
- Isaiah “Zae” Frederich, 23, salesperson (Paducah, KY)
- Jimmy Heagerty, 25, AI consultant (Sarasota, FL)
- Katherine Woodman, 23, server (Gwinnett County, GA)
- Keanu Soto, 33, dungeon master (Miami, FL)
- Kelly Jorgensen, 29, web designer (Burbank, SD)
- Lauren Domingue, 22, bridal consultant (Lafayette, LA)
- Mickey Lee, 35, event curator (Jacksonville, FL)
- Morgan Pope, 33, gamer (Palm Springs, CA)
- Rachel Reilly, 41, TV personality (Concord, NC)
- Rylie Jeffries, 27, professional bull rider (Luther, OK)
- Vince Panaro, 34, unemployed (West Hills, CA)
- Zach Cornell, 27, marketing manager (Cartersville, GA)
One of the big twists of Season 27 was the inclusion of a “mystery guest” as one of the houseguests. This was revealed as Rachel Rielly (+800), who competed on seasons 12 and 13 of Big Brother. After losing in her first attempt, Rachel came out on top in Season 13.

She is a second-tier favorite, but at +800, is a step behind the top contenders. Morgan (+450) is the favorite after the premiere aired on CBS, as bettors put their faith behind the 33-year-old gamer. She is unlikely to draw any negative attention to herself, so I can see her being a major threat.
Making friends and strong allies is all part of the game, and Morgan should have the aspect of the game dialed in. While you could consider her a floater, she’s going to be involved heavily in the social aspect as a friend to most houseguests. Is she going to be fantastic in challenges? Probably not, but it’s unlikely to see her as an early target.
The same can be said for Lauren (+600), who should float under the radar and not get involved in too much drama. Among the underdogs, Adrian Rocha (+1200) is likely to cause noise as a dark horse. Likewise, Katherine Woodman (+1000) opens the season as a compelling Big Brother betting pick.
