I am sorry, but idk how to resolve this to just "3".

In total, or at any of the debates?

Assuming Harris and Trump debate in future (RFK doesn't), does that give us an answer of two or three?

The description says "any".

Which would suggest 2, 2, 2, 2 = 2. (Assuming noone joins the planned debates)

Vs

'In total' Biden, Trump, Harris = 3

@de27 Could you clarify?

If you put it that way I meant it in the sense of total .

You've somehow created a market where the third most predicted outcome (1 participant) is also the most impossible outcome, and yet I suspect this absurdity will remain true until market resolution.

If no debate happens for some reason, then N/A? Or does this resolve to 0?

@Quroe Logically there would be zero people debating if there is no debate. So second option.
