Those interested in buying Twitter will have to move fast. The social media company is telling potential bidders that it wants to wrap up negotiations by October 27, when it reports Q3 earnings, Reuters reports.

Disney and Google’s parent Alphabet are believed to be interested, although it’s not publicly known whether either is prepared to make an offer.

Disney CEO Bob Iger declined at a Boston College event today to confirm or deny that he has hired a banker to investigate a possible bid, Bloomberg reports.

He seemed to leave the door ajar though: Iger noted that companies including Twitter, Netflix, Facebook, Amazon and Apple “are not only technology companies and distributing content, they are starting to invest more and more in making content. Twitter licensing the NFL is a example of that.”

Analysts are divided about whether Disney should pay the $15 billion or so it would take to buy Twitter. The company could provide “a clear advantage to ABC’s News division and to ESPN as a platform to deliver real-time news and sports-related content,” Pivotal Research Group’s Brian Wieser says.

Brean Capital’s Alan Gould says it would “not help with cord cutting for ESPN and the cable networks”

Yet Salesforce.com CEO Marc Benioff all but acknowledged today that he’s weighing a deal.

“It’s in our interest to look at everything,” he told CNBC.  “We have to go deep on everything. We have to understand what is possible for our shareholders and what isn’t. But in the scheme of things, if you look back at my track record as a CEO, I think you’ll find that while I look at a lot of things, I actually pass on most.”

The deal talk lifted Twitter shares 5.7% today — and depressed Salesforce by 5.8%.
