Oracle's stock surged 36% in a day after impressive quarterly results, pushing its market cap past $920 billion. This rally boosted Larry Ellison's net worth to $393 billion, briefly making him the world's richest person. The key catalyst was a $300 billion cloud infrastructure deal with OpenAI, positioning Oracle as a major AI data center provider. Oracle's success is also attributed to its strategic partnership with Nvidia, securing valuable GPUs. CEO Safra Catz's net worth now exceeds $3.4 billion. The company plans to increase its cloud infrastructure revenue from $10.3 billion to $144 billion by 2030, impressing investors despite a slight earnings miss.
