The U.S. Federal Trade Commission has posted notice on its web site today stating that its Bureau of Competition has closed its investigation of the UFC's acquisition of Strikeforce.

Technically the FTC was investigating the purchase of Explosion Entertainment, LLC for $34 million by the UFC's parent company Zuffa LLC in March, 2011. They were looking to see if the purchase violated Section 7 of the Clayton Act or Section 5 of the Federal Trade Commission Act. The purchase was first reported by MMA Fighting's Ariel Helwani.

In the PDF posted on the FTC site, Donald S. Clark, FTC Secretary wrote, "Upon further review of this matter, it now appears that no further action is warranted by the Commission at this time. Accordingly, the investigation has been closed."

Strikeforce was put on the market when its major financial partner, Silicon Valley Sports & Entertainment elected to get out of the MMA business. SVSE owns the San Jose Sharks of the NHL and are seeking to bring another major sports franchise to San Jose.
