So many IPOs taking advantage of the unlimited upside market conditions. Who wouldn't want to go public at markets historical highs that happen every single second of every single day. Its free money for the taking, go public now and get that freeeeeeeeeeee money.
I looked at a few tech companies that have been private for a long time (Corsair, Bentley) and they decided to IPO now after so many years. Smells like 1999.
Its free money so why not now. Why not take advantage of the longest fed back stopped unlimited bull market and get suckered to buy up your stock. Like you said companies going public that have literally been talking about going public for years taking the advantage now. Markets in another phase of an asset bubble but of course it will NOT be believed until well after the fact.
