Disney, a company that's currently valued at $152 billion, is buying Hulu at an expected cost of about $8.6 billion. Disney's gross profit according to Macrotrends is about $28.8 billion per year right now. That's profit, not revenue. I think they can probably afford it.
Not sure why anybody would be surprised. Disney is an institution. Disney might as well announce that their main business competitor is Lockheed Martin Corp.
