## About

This market resolves to the contestant crowned winner of Big Brother Season 28, with the season running from July 2026 through early January 2027. Polymarket's rules resolve to "Other" if no winner is declared by year-end 2026, while Kalshi's rules split payouts across any joint winners and resolve No if the title is never awarded. Nearly all trading activity sits on Kalshi, which has drawn roughly $3.1M in volume against about $99K on Polymarket.

Rick Devens leads the field at a 23.0% consensus, but the spread across platforms is wide: Polymarket US prices him at 27.0% while Kalshi has him at just 16.0%, a 7.5-point gap. Behind him, a cluster of contestants sit within a few points of each other, including Yash Patel (16.5% consensus, ranging from 7.0% on Kalshi to 17.0% on Polymarket US), Mallory Aurichio (16.5%, from 13.0% on Kalshi to 21.0% on Polymarket US) and Dee Valladares (14.5%). No contestant is priced as a dominant favourite.

The cross-platform takeaway: the season is being treated as wide open, and Polymarket US consistently prices the top contenders higher than Kalshi does.
