Jeff Bezos has been making headlines for his expensive purchases, including a $165 million estate in Los Angeles, a $177 million property on Miami's Indian Creek, and his $500 million yacht.

Through his family office, Bezos may have recently made his largest purchase in artificial intelligence.

In January, the founder and executive chairman invested in the $73.6 million Series B round of Perplexity AI, an AI-powered search engine company. He also invested in a $63 million follow-on round in April. By April, the value of Bezos Expeditions' January investment likely doubled, as the company's valuation soared to between $2.5 billion and $3 billion.

In July, he invested in a $300 million Series A round for Skild AI, which develops AI systems for machines and robotics devices.

In a January podcast interview, Bezos stated that AI tools are "discoveries" rather than "inventions" that will significantly affect technology and society. He emphasized that these tools have the potential to benefit and save people more than they can harm or destroy them.

Family offices are increasingly investing in AI, with over three quarters (78%) planning to do so in the next two to three years, according to the UBS Global Family Office Report.

Amazon has been investing heavily in AI, with plans to spend over $100 billion on data centers in the next decade and a recent investment of $4 billion in Anthropic, an AI safety and research firm.

Bezos has recently filed a plan to sell $5 billion worth of Amazon shares, bringing his total sales this year to $13 billion. With this cash, he will have more funds to invest in the growing AI industry.
