I've noticed quite a few of them over the past few months, had not really looked into them very much but I now see many have expired worthless when they don't find mergers and redeem the public shares...
Here are a few that appear to be still alive for now, I'm sure there are quite a few more but I don't really have the time to look into them today. Seems like for whatever reason, those SPACs where the warrants get delisted don't seem to find mergers.
