I myself am using Emacs 26 (from the git master branch), and for me
AUCTeX installed from ELPA works just fine and loads after finding the
first TeX file.  I've tested it just yesterday.

What does C-h f tex-mode RET show you?  Here it shows

,----[ C-h f tex-mode RET ]
| tex-mode is an interactive autoloaded compiled Lisp function in ‘tex-mode.el’.

| (tex-mode)
| 
| Parent mode: ‘text-mode’.

| :override advice: ‘TeX-tex-mode’

| Major mode for editing files of input for TeX, LaTeX, or SliTeX.

Note the :override advice: line which indicates that AUCTeX has been
loaded.

That should not be needed.  Do you have any configs wrt. AUCTeX?  If so,
could you show them?
