John Donahoe, chief executive at eBay, said the company is benefiting from the acceleration in mobile commerce and it expects to generate almost $5bn in merchandise volume this year.
He also said he expected PayPal mobile to exceed $3.5bn in payments volume.
Ebay also unveiled it had benefited from growing adoption of its various mobile apps, which have surpassed 50 million downloads globally.
In a call to investors, Donahoe said: "Mobile commerce continues to accelerate as consumers change the way they shop and pay. It is one way online and offline shopping are blending into a single commerce environment.
"We are at an inflection point in global commerce. In fact, we believe we'll see more change in how people shop and pay over the next three years than we've seen in the past decade."
Last week, eBay announced a partnership with Facebook to give merchants greater exposure on the social networking site and make the shopping experience "more social".
