In the vibrant heart of Athens, amidst the buzz of a burgeoning tech festival, Neil Rimer, a co-founder of the highly successful venture capital firm Index Ventures, delivered a pronouncement that has resonated with unsettling prescience. During a private conversation in late May, Rimer articulated a "strong sense that there will be some sort of a redistribution" of the immense wealth accumulating around the artificial intelligence revolution. He elaborated, "It’ll either be voluntary or it’ll be involuntary, but it’ll happen, and I hope it’s voluntary," adding that he believes tech leaders "can play a leading role in seeing that through." While such a statement might ordinarily be dismissed as conventional populist rhetoric, coming from Rimer, whose firm has consistently delivered exceptional returns over three decades, it carried the weight of a significant public declaration.
Rimer, who stepped back from the day-to-day operations of Index Ventures in 2021, now dedicates a substantial portion of his time to Athens, the city of his wife’s heritage and where his children hold Greek passports. His attire during the interview—a rumpled button-down shirt and jeans—contrasted with the more formal or trendy apparel often favored by his peers in the venture capital world. This understated demeanor belied Index Ventures’ remarkable financial success. Since its inception, the firm has amassed approximately $15 billion in capital from external investors. In the preceding year alone, notable exits, including the initial public offering (IPO) of design platform Figma and the acquisition of cybersecurity firm Wiz by Google, reportedly generated around $9 billion for Index Ventures.
This considerable financial success has been accompanied by Rimer’s engagement in philanthropic endeavors. He serves on the board of Endeavor Greece, an organization dedicated to mentoring entrepreneurs in emerging markets, and previously chaired the board of Human Rights Watch from 2019 to 2025. In late 2021, a significant contribution of $13 million was made by Rimer, his father, and his brothers to McGill University. This donation facilitated the renovation of a campus building, now known as the Rimer Building, and established a new Institute for Indigenous Research and Knowledges.
Rimer’s call for redistribution arrives at a peculiar juncture for philanthropy, a period marked by a discernible decline in traditional charitable giving among the ultra-wealthy, particularly within the tech sector. The Giving Pledge, a commitment launched in 2010 by Warren Buffett and Bill Gates urging billionaires to donate at least half of their fortunes to charity, appears to be losing traction. While 113 families signed the pledge in its initial five years, the number of new signatories subsequently dwindled to 72, then 43, and a mere four in the entirety of 2024. This trend was highlighted in a March report by The New York Times, which detailed how the concept of philanthropy has become increasingly unfashionable among some of the world’s wealthiest individuals in technology. The report noted the sentiment expressed by Elon Musk, the world’s wealthiest person, who has stated that his businesses "are philanthropy."
This pattern extends beyond the Giving Pledge. According to the Stanford Social Innovation Review, while total charitable giving in the United States reached a record $592.5 billion in 2024, the actual number of Americans contributing has declined for five consecutive years, with a 4.5% drop in 2024 alone. The proportion of households making donations has fallen from two-thirds in 2000 to roughly half in the present day. Data from Bank of America and the Lilly Family School further indicates a slip in giving even among affluent households, from 90% in 2017 to 81% in the past year.
The implications of this philanthropic downturn are also observable within Index Ventures’ own investment portfolio. The firm has backed companies like Anthropic, a prominent artificial intelligence research lab. A recent inquiry by Business Insider to a financial planner, Alex Caswell, revealed that many of his newly wealthy clients, often employees of AI firms like Anthropic who are associated with the effective altruism movement, are not prioritizing the donation of substantial portions of their fortunes. While Anthropic offers to match employee donations of up to 25% of their equity to charity, and some clients have utilized this provision, Caswell observed that most are not incorporating significant philanthropy into their long-term financial planning. Instead, their focus is on angel investing or launching their own ventures. "That’s what I’m seeing more than the desire to become philanthropic," Caswell stated in the Business Insider report.
In the absence of widespread voluntary giving, legislative efforts aimed at wealth redistribution are gaining momentum. Voters in California are set to decide on a 5% one-time wealth tax targeting the state’s billionaires. In anticipation of potential tax implications, some prominent figures, including Google co-founders Sergey Brin and Larry Page, have reportedly relocated their primary residences to South Florida.
The prospect of OpenAI’s IPO in 2027 has added another layer of complexity to the wealth distribution debate. One cynical interpretation suggests that the timing of the IPO may be influenced by the proposed California wealth tax, which, if enacted, would calculate an individual’s net worth based on worldwide assets as of the end of the current calendar year.
Predictably, such broad wealth redistribution measures face considerable opposition. Governor Gavin Newsom has expressed reservations, and economists have voiced concerns, citing the experiences of numerous industrialized nations that have repealed similar wealth taxes since 1990 after observing the exodus of wealthy residents.
Alternative, albeit equally controversial, proposals are also being considered. OpenAI has reportedly discussed granting the federal government a 5% equity stake in the company. CEO Sam Altman has framed this as a method of sharing AI’s societal benefits with the public. However, critics view it as a strategic move to secure political favor in Washington. The broader Silicon Valley tech community has historically shown little inclination to involve the government as a stakeholder. Veteran investor Roelof Botha wryly commented during a previous interview, "The most dangerous words in the world are: ‘I’m from the government, and I’m here to help.’"
The sheer volume of wealth concentrated outside of these established mechanisms warrants examination. Elon Musk’s net worth has surpassed $1 trillion, a milestone achieved following SpaceX’s recent IPO. Forbes identified 45 new AI billionaires in its 2026 rankings alone, collectively holding $2.9 trillion, and this figure predates the public offerings of Anthropic and OpenAI. The Business Insider report on Anthropic employees further estimated that once these companies go public, their employees’ collective wealth could be sufficient to purchase nearly one-third of all homes in the San Francisco metropolitan area.
While the current concentration of wealth may feel unprecedented, its historical extremity is a subject of ongoing debate. The share of wealth held by the top 1% of U.S. households reached a record 31.7% in the third quarter of last year, the highest since the Federal Reserve began tracking this data in 1989. This figure is roughly equivalent to the total wealth held by the remaining 90% of households outside the top decile.
This proportion remains below the 45% commanded by the top 1% during the peak of the Gilded Age in 1916. However, when focusing on the very apex of wealth, the situation shifts dramatically. Renowned economist Gabriel Zucman has calculated that around 1910, the four largest fortunes in America accounted for a combined 4% of U.S. GDP. Today, a comparable segment of the population—now comprising 19 households instead of four—holds wealth equivalent to 14% of U.S. GDP.
Rimer’s dichotomy of voluntary versus involuntary redistribution finds historical parallels in periods of comparable wealth concentration in American history. In 1889, at the zenith of the first Gilded Age, Andrew Carnegie penned his influential essay, "The Gospel of Wealth." In it, he argued that affluent individuals should view their fortunes as trusts to be disbursed for the public good during their lifetimes, deeming it a disgrace to die wealthy. This essay became a foundational text for modern philanthropy and served as an intellectual precursor to the Giving Pledge.
However, this voluntary approach did not entirely forestall the emergence of forced redistribution. By the mid-1930s, Louisiana Senator Huey Long had galvanized national support with his "Share Our Wealth" program, advocating for steep taxes on the wealthy to fund a guaranteed income for all Americans. Concerned by Long’s growing influence among the working class, President Franklin D. Roosevelt enacted what the press dubbed the "soak-the-rich tax," which raised the top marginal income tax rate to as high as 79%. While this legislation redistributed less wealth than Long had envisioned, it stands as a stark historical example of politically mandated redistribution, triggered by the perceived inadequacy of voluntary giving in addressing mounting societal pressures.
Rimer, with his extensive career in the technology sector, is well aware of these historical precedents. What particularly fascinates him, however, is the "moral center of tech companies." This fascination traces back to his undergraduate days at Stanford in 1984, when Apple offered its first Macintosh at a discounted price to students. At that time, Steve Jobs and Apple’s other founders were regarded as "heroes" for creating products that Rimer perceived as genuinely beneficial to the world.
What troubles him now, he expressed, is witnessing his own children discuss certain technology companies in a manner reminiscent of how previous generations spoke of defense contractors or cigarette manufacturers—industries that became associated with negative societal consequences.
Critics may point out that Rimer, as an investor in companies like Anthropic, is himself a direct beneficiary of the wealth he suggests will eventually need to be shared. However, his expressed preference is for his fellow beneficiaries to proactively choose to return a portion of their gains, rather than have it taken from them through legislative or other means. Rimer appears to be betting on the inclination of these individuals to opt for the more amicable path, before history imposes a less desirable one.
