I can't predict but i saw there are several things that shows Matic can competition with BSC.

I have used polygon network several times. The transaction was almost instant and fee was very low. On the other hand BSC is costing almost 0.6$-1$ sometimes.

BSC has some good number of dex but Matic don't have like this. May be it's need some time to implant some dex like pancake.
