Interestingly GCP already offers over 75% discounts for n2d (AMD) spot instances that don't rely on any internal market, and the discounts for other families are fairly close.
We see individual spot instances go away every few days which works pretty well for GKE. The older preemptible class of instances restarted every 24 hours which was more of a pain (mitigated a bit with a preemptible killer to spread the restarts out).
