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 July 24, 2026 and July 30, 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 July 30, 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.

This market resolves around Jul 30, 2026, with the outcome confirmed once the eviction is verifiable from credible public reporting. The house guest leaving that night will set the final result, and the market will close immediately after the official announcement, reflecting the real-world event outcome.
Several events could dramatically shift probabilities in this market before Jul 30, 2026. Surprise twists, such as double evictions or abrupt alliance changes, often reshape trader expectations overnight. Public voting surges — especially driven by social media campaigns — can also cause rapid price swings. Performance-based developments like strategic moves, arguments, or voting bloc realignments tend to influence both trader sentiment and short-term odds. Any last-minute twists or nominations disclosed in the final days are likely to produce the most significant market movement as participants rush to adjust positions ahead of resolution.
