This market will resolve at a random time in November before election day. At resolution, this market resolves according to the implied odds given by the main US Elections market conditioned on neither Biden nor Trump winning:

For a simplified example, if the above market has the following probabilities when this market closes:

Joe Biden - 49%

Donald Trump - 47%

Kamala Harris - 3%

Robert F Kennedy Jr. - 1%

Then this market will resolve as following:

Kamala Harris - 75%

Robert F Kennedy Jr. - 25%
