Big Brother Season 27 Odds
We will be adding our updated 2025 Big Brother winner odds, analysis, and predictions after each episode here, so you will continue to have fresh information as the season progresses!
Here are the latest odds, courtesy of BetUS:
| HOUSEGUEST | ODDS |
|---|---|
| Morgan Pope | -300 |
| Ashley Hollis | +250 |
| Vince Panaro | +350 |
| Ava Pearl | +600 |
Additionally, since the show is broadcast on a live feed, a major event could pull the prices off the board momentarily.
The latest Big Brother 27 odds have shifted heavily in favor of Morgan Pope (-300) winning this season! This is the lowest price we’ve seen so far.
The bookies give Morgan a hefty 75% implied probability of being the last houseguest standing. Last week, she was the favorite, but not quite with this strong of odds to win Big Brother Season 27. She had even odds to finish on top, which presented a 50% chance.
Keanu Soto had the second-best Big Brother odds and was evicted, so there are always plenty of twists and turns in this game. The betting odds don’t always tell the entire story, but Morgan appears to be ahead and free, according to the best Big Brother betting sites.
Ashley Hollis (+250) is directly behind Morgan on the latest update. At +250, though, Hollis has just a 28.6% implied probability to win this season. Vince Panaro (+350) follows at 22.2%, while Ava Peal (+600) is the least likely winner, with only a 14.3% chance.

Big Brother Season 27 Latest Events and Updated Betting Pick
As Big Brother approaches the home stretch and the grand finale on Sunday, there isn’t much more time for houseguests to plot their move. Morgan has caught fire down the stretch in the competition department.
She was winless through the first half of the season, but has been picking up huge wins left and right. Whether it’s for the Power of Veto or Head of Household, Morgan is dominating as of late. She has officially been the comp beast of the season after a slow start.

In her biggest win to date, Morgan won the most recent Head of Household to propel her to the top of the mountain and odds board! That guarantees her spot in the finale for Season 27. With Morgan likely to nominate Ava and Ashley, it all comes down to the PoV competition.
Whoever wins holds all the power and can guarantee a spot in the finale alongside Morgan. At this point in the game, everything is adding up to Morgan winning on Sunday.
I bet on Morgan as my Big Brother winner pick in the preseason, and I’m going to continue to ride with her. Mind you, the value, which was there for most of the season, isn’t as solid at -300.
I’ve wagered on Morgan as high as +700 when things were looking bleak for her, but I remained confident in her being the best player. With this in mind, Morgan to win is my final Big Brother prediction!
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.
