Questions
- Is b4 a prediction market?
- No. b⁴ is an opinion market. Prediction markets settle on whether a real-world event happens, checked against an oracle or a data source. b⁴ questions are subjective, so each market settles on what the majority of its voters believe when it closes — the crowd is the oracle. Markets close within 24 hours, and the nightly board resolves live on B Feud.
- How does B Feud work?
- B Feud is b⁴’s live show, every night at 9 PM ET. During the day you stake on the board’s questions in the app. At showtime, host Barry brings each question to the room: you get 20 seconds to call the side and guess what share of the room picked YES, then the room’s answer is revealed and the market resolves. You score for calling the right side and for how close your guess lands, and top scorers can win a share of the night’s prize pool. You can watch and play in the b⁴ app on iOS and Android.
- b4 vs Polymarket: what’s the difference?
- Polymarket is a prediction market: it settles on real-world outcomes using each market’s stated resolution source, usually through UMA’s optimistic oracle, on timelines from minutes to months. b⁴ is an opinion market: it settles on the majority of its own voters at close, within 24 hours, and the nightly board resolves live on B Feud. b⁴ is mobile-only, with stakes from $1 in USDC on Solana.
