Top level is 939 (see the Milestones page for details). A ton of users have probably reached it already. Locoquito and Bassmech20608 are two that I know for sure have reached that level.

The first people reached the top level already a few hours after the release of the update that introduced it. Basically those people just had a few hundred millions or even a few billions stockpiled and continuously bought and sold Bloodmobiles while having the XP Collider activated. This way gets converted to  quickly.
