Will Uber go public this year? That seems to be the big question by investors wondering if they will be able to cash in on the private ride-sharing company's estimated valuation of $62.5 billion.

Uber was hailed one of the top initial public offering prospects for 2016, but its looking less likely that the company will complete the offering before the year is up. CEO Travis Kalanick has continued to push back any notion of an IPO, but investors could force it to ultimately go public, according to Real Money's Anders Keitz.

Here's a look at the 10 largest offerings by U.S. companies listed on the New York Stock Exchange or Nasdaq on record, according to Dealogic.
