In a regulatory filing on Monday, Berkshire said it owned about 14.7 million Activision shares, or 1.9%, worth $1.24 billion on June 30, down from 49.4 million shares, or 6.3%, on March 31.
The filing did not discuss the prices of any sales, or whether Berkshire bought or sold Activision stock in July.
One of Berkshire's portfolio managers invested in Activision in late 2021, with Buffett boosting the stake to nearly 10% in 2022.
Berkshire's remaining Activision stake - 14,658,121 shares - is exactly the size it was before Buffett started buying, suggesting that he has exited the arbitrage bet.
Activision shares rose 10% to $90.99 on July 11 after U.S. District Judge Jacqueline Scott Corley in San Francisco rejected U.S. Federal Trade Commission arguments that the merger would hurt competition in cloud gaming, consoles and subscription services.
