In a shortened holiday week like this one, there are typically few if any companies that plan to price their new IPOs. This week is no exception; there are no new IPOs scheduled. But don't let this quiet period fool you: there are over 50 IPOs sitting in the wings, waiting for their moment to price.

There are also some big names preparing to file, including the two largest ride sharing companies, Uber and Lyft. Reports have been gradually emerging about about their preparations to file publicly.

Some other major names that have made headlines include SurveyMonkey (SVMK  ), which recently filed for a $100 million IPO. The company has had $234 million in revenue over the past 12 months and will list on the Nasdaq most likely before the end of the year. Eventbrite (EB  ) might pop up on the IPO list as early as next week.

So far this year there have been 134 IPOs, which is a short-term record going back to 2014. Many analysts and IPO gurus estimate that there could be a whopping 75 more this year. Aside from a few larger offerings, many Chinese tech and biotech companies are expected to go public before 2019.
