Big Brother season 28 premiered on July 9, 2026. This market will resolve to "Yes" if the listed individual is evicted from Big Brother season 28 between market creation and September 24, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". An eviction will qualify if the individual is removed from further competition within the structure of the competition, regardless of whether it happens during a standard eviction cycle, a surprise vote or double eviction, or based on challenge performance. Disqualification or voluntary departure will not count. If an individual is eliminated but later returns, re-enters, or is reinstated, the original elimination will qualify. However, a declaration of elimination that is immediately and explicitly reversed or nullified during the same episode or broadcast segment (e.g., through a judge’s save, secret participation, public vote, or immunity twist) will not qualify. This market will stay open until the end of the relevant episode to confirm the finality of eviction. This market will remain open until a qualifying eviction is confirmed. However, if no qualifying eviction airs on the official broadcast of Big Brother season 28 by September 24, 2026, 11:59 PM ET, this market will resolve to “No”. The resolution source for this market will be footage from the relevant week of Big Brother Season 28 or a consensus of credible reporting.

Currently, the prevailing sentiment in this market suggests a high probability for a particular houseguest to be evicted, but it’s important to consider how this compares to external predictions. Analyst forecasts and polls often offer a different perspective, frequently based on social media buzz, gameplay analysis, and strategic considerations. Discrepancies between this market and those sources can present opportunities for informed traders, as the market reflects the collective wisdom of those with skin in the game. It's useful to compare the market’s implied probability with the predictions of Big Brother experts.
On Polymarket, this market is priced through a continuous trading mechanism where participants buy and sell shares representing their belief in each outcome. The price of a share directly reflects the probability of that outcome occurring, as determined by supply and demand. As more people buy shares in a particular houseguest being evicted, the price of those shares increases, and the implied probability rises. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market’s price movements are driven by new information, strategic considerations, and the collective intelligence of traders.
This market resolves around Sep 24, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the outcome will be based on who is officially evicted from the Big Brother house during Week 11, as announced on the show. The resolution will reflect the official results broadcast on television and reported by reliable news sources covering the show. Traders will then be able to claim their winnings based on the final outcome of the eviction.
Several factors could significantly impact this market before it resolves. Unexpected alliances, dramatic confrontations, or power shifts within the Big Brother house could all alter perceptions of who is most vulnerable. Any news regarding a houseguest’s gameplay, social standing, or strategic position could also move the market. Furthermore, developments in the Head of Household and Power of Veto competitions will be key catalysts, as these events directly determine who is nominated for eviction and who has the power to save them. These events will all influence trading activity and price fluctuations.
