This is a follow up market for this question below but with a longer timeline:

Resolution criteria:

Restaurant must serve hybrid-rice on a regularly basis, e.g. one-off pop-up events don't count

It doesn't need to be a hybrid between beef and rice, nor must it be cultivated as described in the paper. I count it as long as it's rice with some animal cells cultivated on rice.

I will update criteria as we go

I will not bet on this market.
