During the 2022 Liz Truss administration in the UK, a running joke started that the shelf life of a head of lettuce would outlast her government. This proved true, and the lettuce claimed victory. You can read more about that here: https://en.wikipedia.org/wiki/Liz_Truss_lettuce.

The shelf life of a head of lettuce is 10 days - Will Biden outlast the lettuce?

This market will resolve to "Lettuce" if President Joe Biden officially announces his withdrawal or is confirmed to have withdrawn from the 2024 US presidential race by July 28, 2024, 11:59 PM ET. Otherwise this market will resolve to "Biden".

In the event of any extenuating circumstances that prevent Joe Biden from continuing the race, this market will also resolve to "Lettuce".

The primary resolution source for this market will be official information from Joe Biden or his official/legal representatives, however a consensus of credible reporting will also be used.
