Renaissance Capital posted a chart on their blog showing the number of initial public offerings in each month going back to 1999.
At the height of the tech bubble, there were dozens of companies going public every month. Renaissance notes that the peak came in August 2000, when 66 companies held IPOs.
After the tech bubble burst, IPO activity died down for a few years, then made a bit of a comeback in the mid-2000s. Very few IPOs happened during and immediately after the financial crisis, but the last couple years have seen an increase.
In June, 35 companies went public. That’s the most since that peak month in August 2000.
