Impact got the most reach and the best PPVs. NWA had a spark when it started but is kind of meh outside of promos, ROH is on life support and only exists as long as Sinclair deems it worthy. MLW is #4 for now but they keep getting raided, which I think will catch up to them one day.
NJPW US is booking venues bigger than all 4 promotions listed here so depending on how well they draw, they might take that #3 spot from Impact.
Sinclair needs to hurry up & sell to anthem.
I didn't know NJPW US started already.
I already consider NJPW as one of the power 3 promotions in the US anyway, right alongside WWE & AEW.
since NJPW US is under the umbrella, I guess they don't count for this thread.
