With hype continuing to mount around Grand Theft Auto V, billionaire Ken Griffin's Citadel Investment Group has increased its stake in Take-Two Interactive. According to a December 28 Securities and Exchange Commission document spotted by The Motley Fool, Citadel now owns 5.5 million shares of Take-Two, up from 3 million at the start of October 2012.
Citadel now owns roughly 6 percent of all Take-Two shares. Trading on NASDAQ for the game publisher closed today up 3.48 percent to $11.88 per share.
Griffin is not the first high-profile hedge fund manager to be attracted to Take-Two with GTAV on the horizon. Citadel's deeper investment follows that of fellow billionaire Carl Icahn, who disclosed ownership of 8.7 million Take-Two shares during November 2012.
GTAV is due out this spring for Xbox 360 and PlayStation 3 and is Rockstar Games' most ambitious project to date. Electronic Entertainment Design and Research analyst Jesse Divnich believes the hotly hyped game could sell 25 million or more copies during its first 12 months.
