I have a stupid question: was there a regulatory change in the recent past that made it easier to file for IPOs? Or is this just a coincidence that all these S-1s were filed around the same time?
I've been curious about the increased IPO rate as well. The data is all in EDGAR but it's not easy to find the trends - https://www.sec.gov/cgi-bin/browse-edgar?company=&CIK=&type=... I think it'll be a fun project to scrape the data and create some visualizations with it. Look out for a Show HN from me if you're interested!
Surprisingly, it doesn't look like the overall number of IPOs is any higher this year than in the past.
