They are likely to pick up a slim house majority, but not the senate. Bills have to pass both to get to the president, and even if they (unlikely at this point) manage to eek out a slim majority in the senate, they’d need a super majority (two thirds) to override any presidential veto.

The best the Republican Party will get out of this midterm is being able to assemble some committees, but they’ll have an even split of party members so they won’t actually go anywhere.

Midterms almost always favour the opposition, so it’s interesting that it hasn’t aligned with the expected polling outcome.

In any case, it will be impossible to rollback anything that has been passed recently, but you can expect gridlock for the next 2 years most likely at the federal level. However, at state level, you can bet they’ll all be trying to get in on the battery material cash flow, at the end of the day it’s all about money and what politicians actually do isn’t always what they say (that goes for both sides!)
