They're almost certainly not going to stop making Instant Pots. This is a chapter 11 bankruptcy -- the kind where the business gets restructured but continues to operate.
Faberware and Ninja make some, and I'm sure if the IP IP doesn't get slurped up, Walmart and friends will make store-brand ones. They're not very complicated.
I <3 my Ninja multi-cooker, but they do a HORRIBLE job of marketing the thing with the name alone: Ninja® Foodi® 14-in-1 8-qt. SMART XL Pressure Cooker Steam Fryer with SmartLid®
It's like something I'd read for some white-labelled Chinese product on Amazon; but it's the single most heavily used appliance in my kitchen!
Interestingly, Canadian Tire (very well known establishment up here!) used to sell InstaPot, and pretty much always had it on special. Lately they've shifted toward Ninja brand items.
