Microsoft is thinking about making a play to buy Salesforce, according to Bloomberg.

The computing giant is reportedly evaluating a bid to offer to Salesforce for a potential acquisition, after the cloud service company was approached by another would-be buyer, the Bloomberg report states.

Salesforce’s options “could include rebuffing any buyer, or working out a sale, people with knowledge of the matter told Bloomberg last week.”

The rumour isn’t particularly surprising for those following Microsoft recently. Microsoft emphasized its cloud computing innovation during CEO Satya Nadella‘s tenure, as CNBC notes. “Microsoft’s cloud business grew 106 percent year-over-year in its most recent full quarter, the company reported last month,” CNBC adds.

Microsoft and Salesforce used to be bitter rivals, as BI writes, but last year they struck a partnership to make their software work better together.

Salesforce currently enjoys a market cap of about $48 billion, compared to Microsoft’s roughly $385 billion.

Both Microsoft and Salesforce have not confirmed or denied that they have been in talks about an acquisition.
