PS 50/50 very early suspicious raise....what to do?

[RonFezBuddy]

It's so early in the PS 50/50. At the risk of being weak-tight I can't see him doing this with anything less than AQ but probably with trip 6s.

I hate to let so many chips go but wtf he's gotta have a monster right? He has so many chips that his leverage is what makes me fold, more than the actual bet.

Thoughts?
