LivingSocial, the Washington-based daily deal company, has raised $176 million more from its investors, according to people familiar with the company.

The new round, formally disclosed in a filing with the U.S. Securities and Exchange Commission on Wednesday, values the privately-held company at more than $4 billion, according to the people.

The money for the new fundraising came from a mix of current and new shareholders, including T. Rowe Price, J.P. Morgan Chase, Amazon.com, Grotech Ventures, Steve Case’s Revolution fund and from U.S Venture Partners, the Silicon Valley venture capital firm.

LivingSocial chief executive Tim O’Shaughnessy is son-in-law of Washington Post Co. Chairman Donald E. Graham.
