OSB would delaminate with any moisture that gets on it; it really can't take much water. I think I would use pressure treated plywood; it would last longer.

I have one really old wood barn that I don't use except for a little storage. But, many years ago I refloored the loft with 5/8" plywood I bought at a salvage center. It has held up well, but the thing that I found out is that you need some hay down on the plywood or fresh bales will mold on the bottom slightly due to no air circulation. And when you get a nice 2"-3" layer of hay down on the floor you have to be careful as your feet can slide and cause you to fall when stacking. This was smooth one side plywood.

I've used OSB to cover the old floor for the same reason (seemed weaker or I got heavier ). Haven't had any problems with delamination, but I put a new steel roof on before and I only stack hay on it. So there is little or no moisture available. As Mike mentions, leaving some hay chaff helps with the molding too.
I'd use treated material if I was doing the part where water might be from the wheels (wagons and tractors).

Going to go with 5/8”OSB, when the price comes down of course. Mainly for straw so I’m a little concerned about it being slick but I may throw down some cornstalks to walk on.
I am guessing that the osb will expand just a touch from the outdoor air and when that happens it will likely give you much better footing. Just keep it from getting wet and you should be good.
