Chris Christie is the latest dropout, following on from Suarez, Hurd, Pence, Scott and Burgum. This wasn't totally unexpected, Christie was the second favourite to be next behind Asa Hutchinson:

This leaves five candidates remain in the race (according to 538's definition of a major candidate) with a few days to go until the first votes are cast in the 2024 Republican primaries.

Who will be next?

Resolution criteria:

• I will resolve this market to the relevant candidate when trustworthy news sources such as the BBC and the Guardian are reporting that a candidate has withdrawn from the primaries and suspended their campaign.

• If there is ambiguity as to which of the candidates has withdrawn first (eg. two candidates both say that they are dropping out of the race after the Iowa primaries and the media are not clear on which of them was technically first), the market will resolve equally to those candidates who are dropping out at the same time
