Not many.
OH is by far the most likely given how the new median justice on their state supreme court ruled on the last set of maps.
GA is reasonably probable given they already did it in the 2010's (albeit in a very minor way).
NM and TX both have partisan state supreme court elections and seem to be trending to the party currently out of power.
There's also an outside chance commission amendments could pass with language requiring it in some of the states where signature gathering back in 2020 ground to a halt due to COVID. OR, NV, AR, and OK come to mind as states with one-party control that recently tried to do reform by initiative.
VA is technically doing it given that the 2021 HoD elections were held on the old maps, but not for partisan reasons.
The Ohio Congressional and State Leg. maps only last 4 years because they were not passed in a bipartisan manner. So they'll have to redraw them.
