Christine Wormuth (Current Secretary of the Army)

Michèle Flournoy (Former Under Secretary of Defense for Policy)

Christopher Miller (Former Acting SecDef under Trump)

There is speculation that the current SecDef Lloyd Austin 

will not hold the position for much longer.

This market resolves to the name of the next person who is appointed to the position. It does not count anyone who is only Acting SecDef. This market stays open until there is a new Secretary of Defense, even if that's under the next president.

Please include some information about any names you submit, like their current title or a link to a bio of them so we have some context.
