Creating lab-grown "meat" that tastes, cooks, and digests like real meat is probably not easy. If they can patent some of their techniques, that could make it very difficult for others to compete with them (depending on how easy it is to find alternatives to the patents).
$10B is less than a tenth of Nestle's annual revenue, just to lay out the scope of the food industry. If they were public, it would be a cheap deal for them.
A quarter of the world's population are Muslims or Jews, who would probably appreciate the flavor of bacon without actually eating pigs.
At least another 15% of the world are vegetarian/vegan or aspire to be.
