Speaking at a Washington business gathering, Bezos said it was normal to draw scrutiny but he did not anticipate any actions that would prevent the Internet giant from innovating and growing.
"We are so inventive that whatever regulations are promulgated, that will not stop us from serving customers," Bezos said in a question-and-answer session at a dinner hosted by the Economic Club of Washington.
"Customers are still going to want low prices. They're still going to want fast delivery. They're still going to want a big selection."
Bezos said it was unsurprising and even normal to face questions when a company like Amazon becomes so big.
"All big institutions of any kind are going to be and should be examined, scrutinized and inspected," he said.
"We want to live in a society where people are worried about big institutions. That's OK."
But Bezos said he did not see Amazon - which briefly hit $1 trillion (roughly Rs. 72 lakh crores) in market value - as a monopoly, arguing that online sales still represent a small fraction of overall retail.
"Eighty-five percent of sales is still in the physical world. So that's where we face competition," Bezos said.
Bezos also said no decision had been made on Amazon's second North American headquarters, known as HQ2, for which 20 cities have been selected as finalists, and that the choice would be made as scheduled before the end of the year.
He said "we have made tremendous progress" in the search but offered no clues, despite reports that Amazon board members had visited locations in the Washington suburb of Arlington, Virginia.
