How it works

  1. Bet before the cutoff
  2. Betting closes, the odds are measured for 3 min
  3. Winners split the pool
Full rules

You call whether the Polymarket probability of “Philip Henning” goes up or down in the 3 min after the cutoff; betting is open for 3 min. We compare the average over the last 30 s before the cutoff with the last 30 s before resolution, and winners split the pool in proportion to their stakes. If the line didn’t move, one side is empty, the market is decided or the data is unreliable, everyone gets their stake back in full, with no fee.
