Methodology

Entertainment-specific comparison page for NH-01 Democratic Primary Winner. Polymarket's live quote (Polygon order book) shows the award probability. For awards markets, Polymarket usually has the deepest liquidity; Betfair runs comparable markets for Oscars/Emmys; Manifold for Eurovision.

FAQ

When do award markets resolve?
After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.
What was the top Oscar 2025 market?
Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.
Who can trade Eurovision markets?
Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.
How are reality-TV outcomes verified?
UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.
Are there politics-entertainment crossover markets?
Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.
