Chris Reynolds of Delaware County said he opened the monthly statement from the money transferring service in his email Friday and discovered an ending balance of $92,233,720,368,547,800, the Philadelphia Daily News reported Monday.
"I'm just feeling like a million bucks," Reynolds joked.
Reynolds said his wealth was short-lived, as his balance showed the expected zero when he logged into PayPal.
He said he would have used his quadrillions to get rid of debts.
"I'm a very responsible guy," he said. "I would pay the national debt down first. Then I would buy the Phillies, if I could get a great price."
A PayPal spokeswoman said she could not disclose customer-account information due to privacy policies, but she would look into the matter.
