Rupert Murdoch-controlled Twenty-First Century Fox has held talks to sell most of the company to Walt Disney Co, CNBC reported on Monday, citing unnamed people familiar with the matter.
Fox's shares rose 5.8 percent to $26.40 in afternoon trading in response. Disney's shares were up 1.2 pct at $99.86.
A Disney spokesman did not immediately respond to a request for comment while Fox was not immediately available for comment.
Disney, which under U.S. rules could not own two broadcast networks, would not purchase all of Fox, CNBC reported, citing the same sources.
Disney would not seek to buy Fox's sports programming assets for fear of running foul of antitrust laws with its own ESPN network, and would also not buy Fox News or Fox's local broadcasting affiliates, the report said.
