Prediction Markets on 2024 U.S. Presidential Election

The PredictIt prediction market has opened markets on the nominees of the Democrat and Republican parties for U.S. president in 2024 as well as the eventual winner of the general election. Current standings (2021-10-20 at 19:47 UTC) are:

The way prediction markets work is that you buy shares in Yes or No for your choice at a price of US$1 times the percentage offered in the market. When the event happens and the outcome is known, shares in the correct prediction pay off at par while all others are worthless. So, for example, you could buy 100 shares of Trump president in 2024 for US$ 29 and if he wins the election, you collect US$ 100.

I found the prediction of Biden as the Democrat nominee surprisingly low.


You have to price in life expectancy (another aneurysm or breakthrough COVID) plus mental decline.


I have a somewhat practiced physician’s eye, imperfect as it may be. In my experience, Biden’s mien definitely does not comport with a life expectancy sufficient for another term. When he has been less carefully resurrected - sorry, made up, he doesn’t look very likely to live out this term.
