Salesforce is no longer interested in acquiring Twitter, following weeks of talks.
Twitter is "not the right fit for us for many different reasons," Salesforce CEO Marc Benioff told the Financial Times on Friday.
Fidelity Investments, which holds a 14 percent stake in Salesforce, has reportedly pushed back against a deal with the social network.
It was previously reported Twitter told potential acquirers it wanted to conclude negotiations to sell itself by the time it reports its third quarter earnings on Oct. 27.
It's not clear what other companies are still interested in buying Twitter, if any. Google and Disney pulled out of talks last week.
Twitter's stock fell 8-percent after Benioff's comments on Friday.
