Resolves YES if one can purchase a cultured meat product (a.k.a. "cultivated meat", "lab grown meat", etc.) in a major grocery chain store in the US. Non-cell based mock meats, like the Impossible Burger, do not count.

Sep 23, 6:59pm: Clarifying resolution criteria: I'd resolve YES if any of the following occur:

• A major grocery store (Whole Foods, Walmart, Kroger, etc.) started carrying cultured meat in >10 stores

• There are at least 5 major cities in which it's possible to purchase cultured meat (e.g. through specialty grocery stores)

• I can order cultured meat online and have it delivered. -- In this case, I'd also add the condition that the price be within an order-of-magnitude of "normal" meat products, to guard against technically matching this by offering a $1k burger orderable online.
