How to read a multi-outcome event
Each outcome above is its own market with its own YES price, and each price is the crowd’s estimated probability of that outcome. Because only one can happen, the percentages across all 9 outcomes add up to roughly 100%. Volume is the sum across every outcome, so it can exceed the money actually at risk — buying NO on one outcome is economically close to buying YES across the others.
