How OG works
Every OG contract pays US$1 if your prediction is right and nothing if it's wrong, so a price of 15¢ means the market sees roughly a 15% chance. This is how OG explains it on each market page (screenshot taken 27 September 2026):

Market pages also show a live order book: the prices other traders are asking and bidding, and how many contracts are available at each price. See limit orders vs market orders for how to use it.
