No one was in a better mood last week than Larry Ellison—the Oracle cofounder shot up Forbes’ billionaire rankings list, reaching the number two spot, right below his close friend Elon Musk.

Ellison’s net worth now stands tall at $250.9 billion after Oracle’s recent earnings report triggered its shares to skyrocket.

With approximately 41% of Oracle’s shares in his name, the cloud-computing mogul saw his net worth climb by over $40 billion in a matter of days. On Thursday last week, his fortune grew by $25 billion, and increased by another $16 billion on Friday: easily two of the largest daily swells in billionaire net worth that week, according to Forbes.

Now Ellison has overtaken Amazon’s founder, Jeff Bezos, who is currently worth $229 billion, and Mark Zuckerberg, who has a $240 billion net worth, in the billionaires club.

The one person he hasn’t topped yet is Elon Musk—Ellison’s close friend, who is still the world’s wealthiest man with $405 billion in riches. There’s nearly a $155 billion difference between their respective net worths, so Ellison has his work cut out for him if he ever hopes to reach number one.
