The IPO market is likely to surge next month, with at least six private companies planning to go public after the Labor Day holiday, according to a new Wall Street Journal report.

The U.S. market for IPOs has been in dire need of rescue: As of late August, 2016 is on track to be the worst year for IPOs since the financial crisis, with only 63 companies listing on U.S. exchanges and raising just $12.9 billion total, according to Dealogic.

Still, analysts and bankers expect the activity to slow in the following weeks, due to political uncertainty leading up to the U.S. presidential elections in November. "We've been preaching 'go now' to the right companies that have been ready for some time," said J.D. Moriarty, the head of U.S. equity capital markets at Bank of America, in an interview with the Journal.

A period of calm in recent weeks, coupled with rising stock prices, have encouraged some Inc. 5000 honorees to take the plunge. Nutanix, a software maker, made No. 86 on this year's list due to its 3,566 percent growth over a three-year period (between 2012 and 2015). It's among the few companies valued in the billion-dollar range reportedly planning an IPO this year.

Meanwhile, Yeti Holdings, which makes smart coolers, landed a spot on the Inc. 5000 at No. 510--having grown sales by 748 percent (between 2012 and 2015). The company is also said to be planning an IPO.

Nutanix declined to comment, and Yeti did not immediately respond to a phone call from Inc.

Other private companies expected to go public next month include Valvoline, an automotive maintenance company; J.A. Cosmetics, a beauty retailer; and the Carlyle Group, a Bermuda-based bank.

Amid fears of a bubble bust, a number of companies have chosen to either halt or delay their IPOs or merge with public companies. International crises have also contributed to these decisions. When the U.K. voted in June to leave the E.U., for instance, the S&P 500 Index dropped 5.3 percent in just two days, though it ultimately recovered to a record high by the end of the month.
