Deal to buy SaaS company would be largest ever tech deal.
Salesforce is speaking with financial advisers to help it field offers after it was approached by a potential buyer.
Bloomberg reported that such a deal would be one of the largest and most expensive technology deals to ever take place, with Salesforce currently valued at around $49 billion.
If the deal were to be successful, the total amount spent on mergers and acquisitions in 2015 would surpass the $80 billion mark, more than the total sum of money spent in 2014.
Rumours as to who could potentially afford to buy the SaaS company are flying, with Oracle being placed at the top of the list and other companies such as IBM, SAP, Google and HP also being mentioned.
Salesforce stock has risen by 12% since the rumours started.
