Resolution Criteria

This market resolves YES if a fair coin flip results in heads, and NO if it results in tails. The flip must be conducted daily at a specified time (e.g., 12:00 PM UTC) using a standard fair coin or equivalent randomization method (such as a random number generator with 50/50 probability). Each day's outcome is independent and does not affect subsequent days' flips.

Background

A fair coin flip has a 50% probability of landing on either heads or tails, making it a pure random event with no predictive value. This market serves as a baseline test of prediction market mechanics and trader calibration.

  • Update 2026-03-15 (PST) (AI summary of creator comment): The coin flip will use FairlyRandom as the randomization method to ensure verifiable results.

  • 1- yes

  • 2- no

  • Update 2026-03-15 (PST) (AI summary of creator comment): The coin flip result for this resolution is No (tails), as determined by FairlyRandom.

If I had know that you would bet on it after the coin flip, I would have set my limit orders to expire before closing. Also, why did this close early?
