According to a regulatory filing, Berkshire Hathaway, led by Warren Buffett, acquired close to $1 billion in Activision Blizzard stock in the fourth quarter, swooping in before Microsoft decided to acquire the video game publisher for $68.7 billion. Microsoft had, in mid-January, revealed its intention to purchase Activision Blizzard for $95 per share, driving the stock up 25% to above $82. Buffett and Berkshire stand to make a hefty profit when the Microsoft takeover concludes, making this the biggest transaction ever made by a U.S. technology firm.
