Oracle founder, CTO and billionaire Larry Ellison disclosed that his second-largest personal investment is in Tesla.

He made the statements at the financial analyst meeting at the Oracle OpenWorld conference on Thursday.

"My second-largest investment, I will disclose it now, I am not sure people know I am very close friends to Elon Musk and I am a very big investor in Tesla," Ellison said on the call. "And so Tesla had a good day, and I think Tesla has a lot of upside."

Ellison also criticized media coverage of Musk, the Tesla and SpaceX CEO, suggesting it is overly harsh and shortsighted.
