Some people buy into the idea of "the IPO window," a time when it's seen as safe to go public. Even people who don't buy into it can't deny that no one wanted to touch an IPO in March and April, so there's some pent-up demand.

These three companies are also all very different as businesses. Their biggest commonalities are the people they hire and where they're located. After that, they look pretty different.

Not at all. Look at last summer's IPOs.

Are they really all that related?

The IPO process takes a while, so is it really that surprising that a bunch of companies might have overlapping periods of IPO activity?

If a bunch of companies in the same sector, that compete with each other, went to IPO around the same time, that might be a _little_ weird, but this is largely just a coincidence. AirBnB has been anticipated for a while, Palantir needs the cash, and Corsair, well, I dunno what's really up there, but they're gonna try to IPO too. Either way, it mainly seems like a coincidence for these three.

I imagine a lot of people are expecting the economy to go through a prolonged, rough recovery from the beating that has been most of 2020. The Trump administration has done just about everything possible to kick the can down the road. Might as well IPO now while you can take advantage of a strong stock market, before reality sets in.
