Definitely shop your resume ASAP, simply because there's no downside: you don't have to quit unless/until you get a better offer, and if the money does come in you're set.

The company I worked for went through this a few years ago, but pulled out of it and was doing well for a while.

Nonetheless I got a zero-day shitcan from them about a year ago (let go on Wednesday and paid through Friday, with another half month of medical/dental).

Don't be more loyal to the company than they would be to you.
