In documents filed with U.S. Securities and Exchange Commission, Harrah's said it would sell an unspecified number of shares "to fund a near-term pipeline of growth projects and for general corporate purposes."
It was unclear how many shares of stock Harrah's would be sold and on which market the company would be listed, but the company said it would sell shares "as soon as practicable after this registration statement becomes effective."
Company officials said they could not comment on the filing because of SEC regulations.
One observer thought the initial public offering could raise between $500 million and $1 billion for Harrah's.
