Oracle's Stock Crash Looks Embarrassing for Billionaire Founder Larry Ellison

Oracle stock has plunged 64% from its September 2025 all-time high, erasing nearly $600 billion in market cap and leaving shares down 50% over the past year. Larry Ellison's net worth collapsed from ~$388 billion to ~$175 billion in under 10 months, dropping him from second-richest person to eighth on the Bloomberg Billionaires Index.

Why it matters: Investors are questioning whether Oracle's AI-fueled growth expectations were too aggressive, with concerns over heavy data center spending, margin pressure, and intense competition from Microsoft Azure, AWS, and Google Cloud.
