Oracle founder Larry Ellison has adopted a trading plan allowing him to sell up to 50 million Oracle shares, worth about $7.5 billion, by October 24. The potential sale would be unusually large for Ellison, who has rarely sold substantial amounts of Oracle stock and has not sold more than 25,000 shares at any given time this century. Ellison holds more than 40% of the company, although the available source is truncated after that figure. The planned disposal comes as Oracle reports higher data-centre revenue while taking on debt to expand its role in artificial intelligence infrastructure, fueling investor concerns about its exposure to AI.
