Jeff Bezos is betting big on artificial intelligence even as some investors worry about a bubble. The five AI startup investments represented 10% of all such family office investments that month, based on data from Fintrx, a private wealth intelligence platform.
That makes Bezos Expeditions the most prolific family office in terms of direct investments so far in 2026.
Family offices have increasingly turned to direct investments in private companies as a way to gain higher returns and more control. Bezos Expeditions has been at the forefront, making eight direct investments so far in 2026, more than any other family office tracked by Fintrx. This aggressive approach reflects Bezos's personal conviction in the transformative potential of AI, as evidenced by his role as cofounder of Prometheus.
The biggest deal was for Prometheus, a physical AI startup where Bezos is cofounder and co-CEO. Prometheus raised a Series B funding round of $12 billion. That round valued the company at about $41 billion. In total, Prometheus has raised more than $18 billion to date.

Prometheus is developing a system called an "artificial engineer" intended to hasten the design and production of tangible goods, such as jet engines and pharmaceuticals. Bezos told CNBC's David Faber on June 11 that the goal is to build a set of tools that accelerate the invention loop from idea to manufacturing to a useful object.
Besides Prometheus, Bezos Expeditions added four other new startups to its portfolio in June. One is General Intuition, a company that trains spatial AI models by processing vast amounts of video game footage. The round also attracted Hillspire, the wealth management vehicle of former Google CEO Eric Schmidt, for General Intuition's $320 million Series A. Other new portfolio companies include CuspAI, which builds AI models for chemistry; Generalist, a startup working on helping robots manage more complicated tasks; and Flourish, which develops AI models inspired by the human brain. Bezos Expeditions co-led the fundraises for CuspAI and Flourish.
Bezos is not worried about a potential AI bubble. In a May 2026 interview on CNBC's "Squawk Box," he said, "Even if it does turn out to be a bubble, you shouldn't worry about it because the bubble is driving investment and a lot of the investment is going to turn out to be very healthy." He added, "Investors at this moment haven't learned yet how to discriminate between good ideas and bad ideas, and that's OK, because the good ideas will pay for all of the losers."
In a June 11, 2026 interview with CNBC's David Faber, Bezos explained his bigger view.
"What drives the wealth of nations? What drives civilizational wealth? ... The answer is invention." He said Prometheus is building tools that accelerate the invention loop, shortening the time from idea to manufacturing to a useful object.
Currently, Bezos Expeditions leads all family offices in direct investments for 2026.
