Multi-Outcome Prediction Markets: Understanding the Complexities

Multi-outcome prediction markets are complex systems that can be tricky to understand. They ask one question and split it into several Yes or No rows, each with its own price.

The prices for these rows trade independently, so the total often comes to more than 100 cents. This can be normal in certain types of markets, such as those where multiple outcomes are possible.

For example, a market that asks what price Bitcoin will reach in 2026 might have four rows with different targets: up to $85,000 at 81 cents for Yes, up to $90,000 at 60 cents, up to $95,000 at 37 cents, and down to $70,000 at 48 cents.

In this case, the total comes to 226 cents, more than double 100. However, this is still a valid result because the upside rows overlap.

When checking these markets, it's essential to treat each row separately and look for any rows that are out of order. In price ladders, higher targets should always be cheaper than lower ones.
