Market Brief
- Big Brother 28 premiered on CBS on July 9, 2026 with 14 first-time contestants including an MMA fighter and a RuPaul's Drag Race alum.
- Subtitled 'Time Trip,' the 28th edition of the programme also features three surprise crossover/return guests, Survivor winner Dee Valladares, Survivor alum Rick Devens, and former Big Brother contestant Angela Murray.
- Valladares has been an early favorite on the show, shooting to the top spot on Kalshi in the early weeks, leading second-place favorite Rick Devens.
- The Time Trip format has scrambled alliances more than a usual season, with a time-travel theme and time-based rooms that houseguests have to navigate.
- Prediction markets have become a genuine spoiler problem for reality TV this season - Kalshi's contestant pricing has, in past seasons, tipped off eventual winners and eliminations.
How This Resolves
- Resolves to whichever houseguest is named the winner on the live finale, currently set for a 90-minute special on Thursday, Oct 1, 2026 - the last one standing takes home the $750,000 grand prize.
- Kalshi's own wording: "If [houseguest] are officially declared the winner of Big Brother Season 28, then the market resolves to Yes." Kalshi and Polymarket both list every houseguest as a separate Yes/No contract rather than one multi-choice market, so each name's price is its own independent read on the field, not a slice of a fixed 100%.
- Only the 5 real contenders by current price are tracked here out of 17 total houseguests - the rest are sitting at a nominal 1-2% on both platforms with no realistic path to the money.
