Ellison's net worth surged to an estimated $393 billion after Oracle's stock rocketed following a blockbuster earnings report, driven by multi-billion-dollar AI customer orders.
Conversely, shares in Elon Musk's primary holding, Tesla, have declined by 14 per cent so far this year.
While Bloomberg reported Ellison's brief ascent, Forbes, another prominent wealth tracker, still places Musk at the pinnacle, attributing the disparity to differing valuation methodologies for private holdings like SpaceX.
