The artificial intelligence gold rush is not just creating new technologies — it is also rapidly redistributing global wealth.
In the third quarter of 2025, corporate insiders from some of the biggest AI-driven companies sold billions of dollars’ worth of stock, reshaping the billionaire landscape in Silicon Valley and beyond.
From CoreWeave’s post-IPO surge to Arista Networks’ record rally and Nvidia’s soaring valuation, the year has become a defining one for AI-linked fortunes, according to Bloomberg data.
New Jersey-based CoreWeave, once a crypto-mining venture, has become the latest symbol of how fast AI can mint new billionaires.
The company’s insiders, whose shares unlocked in mid-August, sold over $1 billion worth of stock — their first opportunity since the firm’s March listing.
The sales placed CoreWeave’s executives among the top ten individual insider sellers of the quarter.
CoreWeave insiders lead the AI wealth reshuffle
Bloomberg data show that CoreWeave’s co-founder Brannin McBee and director Jack Cogen were among those who capitalized on the company’s 250% post-IPO surge.
McBee sold 4 million shares for $425.9 million, while Cogen sold more than 5.1 million shares worth $477.1 million.
Both transactions were conducted under pre-arranged 10b5-1 trading plans tied to market thresholds.
CoreWeave’s largest investor, Magnetar Financial LLC, also joined the wave of profit-taking.
The Illinois-based hedge fund sold nearly $1.9 billion worth of stock in the same quarter, although it retained more than 20% of the company’s Class A shares, according to Bloomberg.
The combined insider and institutional sell-off highlights how swiftly the AI market has converted paper gains into real capital.
The company’s transformation from cryptocurrency mining to AI infrastructure has been lucrative for early backers.
Cogen, who joined CoreWeave’s board in 2017, saw his long-term bet on data-centre capacity pay off as AI demand exploded.
McBee, originally an energy trader, now holds an estimated net worth of $3.9 billion, Bloomberg noted.
AI stocks dominate insider sales in 2025
CoreWeave was not alone. Seven of the top ten insider sellers of the third quarter came from firms making money from artificial intelligence.
The list reads like a who’s who of the new AI economy — Nvidia, Arista Networks, Snowflake, AppLovin, Robinhood, and Coinbase.
Nvidia’s chief executive, Jensen Huang, sold 4.3 million shares worth $743.3 million under his 10b5-1 plan.
Arista Networks’ Jayshree Ullal offloaded 6.4 million shares valued at $861.4 million, riding the company’s record share price as AI infrastructure spending accelerated.
Snowflake’s chairman, Frank Slootman, sold $462.8 million worth of stock, continuing his exit from executive duties.
Even outside the AI hardware sphere, technology executives benefited from the sector’s halo effect.
AppLovin’s director, Herald Chen, sold 700,000 shares for $312.7 million, while Robinhood’s Baiju Bhatt and Coinbase’s Brian Armstrong monetised the broader digital-asset rebound, earning $296.2 million and $268.2 million respectively.
Tech wealth concentrations intensify amid AI surge
Behind the numbers lies a striking pattern — AI is concentrating wealth faster than any previous technology wave.
As investors pour billions into infrastructure, chips, and cloud-based computing, insiders who took companies public in the past two years are reaping record gains.
Amazon’s founder, Jeff Bezos, topped the quarter’s list, selling 21.7 million shares worth $4.9 billion under a pre-arranged plan, Bloomberg reported. The sale eclipsed all other insider transactions combined.
Bezos, who has now sold over $50 billion worth of Amazon stock since 2002, remains one of the biggest beneficiaries of the tech boom that set the stage for the AI era.
The third quarter marked a milestone: insiders across AI-related companies collectively sold tens of billions of dollars’ worth of shares, reflecting not only confidence in liquidity but also the maturing of a market once driven by speculative hype.
For CoreWeave and its peers, the message is clear — AI is not just transforming industries but also rewriting the global billionaire rankings.
