Groupon has secured $500 million of the $950 million in funding it is looking to raise, according to a Securities and Exchange Commission filing.

Groupon's total offering amount is $950,091,047. Of that, the company has already raised $500,000,141 and still wants $450,090,906.

On Tuesday, Groupon founder and chief executive Andrew Mason tweeted that "Groupon is in the process of completing a new round of financing - we'll let everyone know when there's more to announce." Beyond that, the company has not commented publicly on its funding activities.

News of the $950 million funding round broke earlier this week when VC Experts reported that Groupon had "filed a certificate to authorize a $950 million Series G round of preferred stock." VC Experts put the value of Groupon at $6.4 billion, though depending on how the company's shares are issued, that could jump to to $7.8 billion, the site said.

The news comes several weeks after reports that Google was looking to buy Groupon. Reports originally put the deal at $2.5 billion, but that later skyrocketed to over $5 billion. By early December, however, talks between Google and Groupon reportedly crumbled.
