How much would $100 on Polymarket have made?

It depends on the price you paid. A share pays $1 if its outcome wins, so $100 at 25¢ buys 400 shares and returns $400, while $100 at 90¢ buys about 111 shares and returns about $111. The lower the price at the time, the bigger the payout when the outcome wins and the more often the bet loses.

Are these returns realistic?

They are hindsight figures. Each page picks a price after the winner is known, and nobody knew the winner at the time. Prices in a new market are often thin, a quote is not a guaranteed fill, and fees are not included. Treat the numbers as a way to understand how odds and payouts work, not as a forecast.

Can I still bet on these markets?

No. Every market on this page has resolved, so its shares can no longer be traded. Each page links to live markets on similar questions.

Where do the prices come from?

From Polymarket's public price-history endpoint, sampled every 12 hours (daily where Polymarket only serves daily history) for the winning outcome of each market. The method box at the bottom of each page explains the formula and the limits.

How we calculate this

A Polymarket share costs between $0 and $1 and pays $1 if its outcome wins. So a bet of $100 at a price of 40¢ buys 250 shares and returns $250 if the outcome wins and nothing if it loses. The return is $1 divided by the price.

Prices come from Polymarket’s public price-history endpoint, sampled every 12 hours (daily where only daily history is served) for the winning outcome of each market. The lowest price is the lowest sample after the first day of trading. Samples can miss a brief low, a quote is not a guaranteed fill, and fees are not included; see our guide to Polymarket fees.
