CNBC is reporting that Comcast may outbid Disney for the 21st Century Fox assets that are up for sale. CNBC is owned by Comcast. It was reported that 21st Century Fox preferred the Disney deal because it would face less regulatory obstacles. Comcast is looking at how the AT&T - Time Warner deal is going through the courts. If that merger is allowed to go through, Comcast believes that they would have an easier time acquiring Fox assets.
If Comcast does make a bid, Disney could consider raising their bid in order to gain the assets. The report does stress that Comcast has not made a decision on if they will move forward. In many ways, it appears the media companies are waiting to see what happens with AT&T/Time Warner
