That depends on how the markdown filetype is being detected, by
filename extension or by file content.

If the markdown filetype is being detected by file content,
executing

:filetype detect

after you've written a number of lines of recognizable markdown
should work.

If the markdown filetype is being detected by filename extension,
you'll have to give your buffer a name, e.g.,

:f myfile

before executing

:filetype detect

The simplest may be to execute

:set ft=markdown

or whatever the markdown filetype is actually called, as soon as you
open a new, empty window.
