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 10, 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 10, 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.

Comparing prediction market odds to analyst forecasts reveals interesting insights into collective wisdom versus expert opinion. Often, this market demonstrates a different perspective than traditional polls or expert predictions, potentially incorporating a wider range of information and real-time reactions to events within the Big Brother house. Discrepancies can arise from differing methodologies or biases, with prediction markets reflecting the 'wisdom of the crowd' and analysts relying on individual assessments. It's useful to consider both when evaluating the likely outcome of the eviction.
On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell shares representing their belief in each houseguest’s chance of being evicted. The price of these shares fluctuates based on supply and demand, effectively creating a probability distribution. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The higher the demand for shares in a particular houseguest, the higher their implied probability of eviction becomes, and vice versa. This dynamic pricing reflects the aggregated predictions of all participants in the market.
This market resolves around Sep 10, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the market will resolve to the houseguest who is officially evicted from the Big Brother house during Week 9, as announced by the show’s producers. The resolution will be based on the official results broadcast on television and reported by reliable news sources covering the show. The market will then pay out to those who correctly predicted the evicted houseguest.
Several signals or events could significantly move this market before it resolves. Any major developments within the Big Brother house – such as power shifts, alliance formations, or dramatic confrontations – could alter perceptions of houseguest vulnerability. Unexpected twists introduced by the show’s producers, or revelations about houseguest strategies, could also have a substantial impact. Public opinion, as reflected in social media trends and fan polls, might also influence trading activity and shift the odds in this market. Changes in these factors will be reflected in the trading volume.
