You need three stamps, and it'll take a while to get. Only one or two events per patch give stamps, so out just takes time. They're supposed to change the event card every once in a while, but I was able to get a positive chaos in kms recently through the card, and I'm pretty sure I got my first stamps back when the card came out. The event card itself is not an event, so you don't have to worry about losing your chance at a positive chaos anytime soon.
