Fred Wilson made an interesting remark in his recent post about the current "IPO bonanza" that is taking place in the tech space. He is, of course, talking about the recent IPO of Lyft, the recent S-1 filings from Pinterest and others, and the expected filings from Uber, Airbnb, and so on.

After listing the benefits of going public, he went on to say that this bonanza will surely also mean that it is going to become even more unaffordable in the Bay Area. Part of this is perhaps self-serving, since he operates a VC firm out of NYC. (Take your money and move to NYC.)

But the data suggests that there is truth to this.

When Twitter when public in 2013, it was estimated that it created some 1,600 millionaires. This is great for the local startup ecosystem as many of these beneficiaries could go on to found their own companies and create a whole new batch of jobs. The money gets recycled.

But what does it do to the local housing market -- especially a supply-constrained one like that of the Bay Area where it is difficult to build?

In 2018, Barney Hartman-Glaser, Mark Thibodeau, and Jiro Yoshida penned a paper called, Cash to Spend: IPO Wealth and House Prices. In it, they looked at the impact of IPOs on local home prices in California from 1993 through to 2017.

What they found, among other things, was a "positive and significant association between local house price changes and firms going public." The price increases were also found to be the greatest the closer you get to the headquarters of the firm that just went public.
