The number of initial public offerings has surged to 182 so far this year, raising $79 billion, or already more money than U.S. IPOs raised in all of last year, according to research from IPOBoutique. And the second half of 2021 looks to be just as busy, with a big group of tech firms queued up to go public, including Robinhood, Rivian and possibly Instacart.

Driving the rush is the stock market’s continued rally, which shows few signs of faltering despite concerns about inflation. Just counting traditional U.S. IPOs that raise at least $20 million, analysts at IPOBoutique anticipate another 50 companies could go public before Labor Day, a pace which could bring the year’s total to more than 300. Below, we profile 23 companies that could go public in the second half of the year or early next year.
