No, Fusion 12 supports Big Sur as both the host OS or as a guest OS, there’s no support currently for the M1 though.
Moderator note: Moved thread from Platform Status to VMware Fusion Discussions
The "platform" part in "Platform Status" is about the Forum software platform
A bit of a confusing name considering that VMware also uses platforms in a different way.
Sadly VMware cannot make any statements about progress on their M1 support due to them being a publicly traded company. As such we'll have to wait until a beta becomes available.
There's a few threads about this, this might be the most active one:
