SpaceX And Anthropic Plan To Go Public — Here's What Happened After The 10 Biggest IPOs In History

Expectations that SpaceX, OpenAI and Anthropic could all reach public markets within months has reignited investor appetite for initial public offerings.

Bank of America's chief investment strategist, Michael Hartnett, went searching for a historical precedent, and found one hidden within the 10 largest IPOs in market history.

In his latest "The Flow Show" note, Hartnett analyzed not the IPO stocks themselves, but the performance of each company's home-market equity index over the following three, six, nine and 12 months after the listing.

The question Hartnett is really asking is whether a giant listing tells you anything about what stocks do next.

The answer is that it depends entirely on which giant you pick.
