Is Comcast going to play spoiler?

Shares of 21st Century Fox jumped more than 4 percent Monday evening after Reuters reported that Comcast is preparing to upend Disney’s $52 billion deal to acquire most of Fox’s assets.

According to Reuters, Comcast is holding discussions with investment banks about financing an all-cash deal, but the cable giant is waiting on a judge to rule next month on the Department of Justice’s suit to block AT&T’s acquisition of Time Warner before submitting an offer, Reuters reported.
