Several markets exist for the popular vote share for specific 3rd-party candidates, or for the single 3rd-party candidate with the most votes.

This market captures the total combined popular vote share of ALL candidates other than the Republican party candidate (presumptively Donald Trump) and Democratic party candidate (presumptively Joe Biden).

Where ".99" appears in the answers, this is shorthand for .99... repeating.

The close date of this market may be extended if vote shares are not clear by the weekend following the election - for example, if re-counts are credibly demanded, or if votes are still being counted and the vote shares are near any of the thresholds in the answers.
