The only polls that matter are those in six key states that Biden won in 2020 that Trump has a real shot at flipping: Arizona, Georgia, Nevada, Wisconsin, Michigan, and Pennsylvania. It's extremely unlikely at this point that any other states will flip from the 2020 results.
Current polling averages have Trump winning Nevada and Georgia handily and Trump carrying a small but consistent lead in Arizona, Michigan, and Pennsylvania. Wisconsin has gone back and forth and could easily go either way. If Trump does flip Nevada and Georgia, which seems likely as of right now, he only needs one of Michigan or Pennsylvania, or both Wisconsin and Arizona put him over the top.
Oddly enough, Virginia is showing as a tie, but I think the Ds have built in enough advantages for themselves in Virginia that it stays blue regardless.
All that said, a lot can change between now and Election Day.
