Musk, who said earlier in the month that he was relocating to Texas from California, was responding to a tweet that suggested his private jet had arrived in Hawaii on Sunday.
Ellison, who joined Tesla’s board in 2018, had also announced in December that he was leaving California to work from the Hawaiian island of Lanai.
Oracle announced earlier this month that the company was moving its corporate headquarters to Austin, Texas.
"I've received a number of inquiries about whether or not I will be moving to Texas," Ellison wrote in a memo to Oracle's employees.
I’ve moved to the State of Hawaii and I’ll be using the power of Zoom to work from the island of Lanai.
In addition to his three hotels, he also owns a significant chunk of the housing stock as well as the main grocery store and the monthly newspaper there.
