Jassy tried to persuade Wall Street that Amazon will be just fine, despite worries about a tariff war with China.

Amazon CEO Andy Jassy says the company hasn’t seen a meaningful impact from tariffs yet, citing stable prices and forward-buying—but warns of uncertainty ahead.

People are “buying a lot of their everyday essentials at Amazon” and the company has “extremely large selections” and “hundreds of millions of SKUs,” Jassy says, which means that “we’re often able to weather challenging conditions better than others.”
