During a conversation in Athens in late May, Neil Rimer articulated a sentiment that has resonated deeply: amidst the burgeoning wealth generated by artificial intelligence, he foresees "a strong sense that there will be some sort of a redistribution." He elaborated, stating, "It’ll either be voluntary or it’ll be involuntary, but it’ll happen, and I hope it’s voluntary," further suggesting that tech leaders "can play a leading role in seeing that through."
While such a statement might typically be perceived as conventional populism, its origin from Rimer—a co-founder of Index Ventures, one of the most successful venture capital firms of the past three decades—lends it considerable weight and makes it particularly striking.
Rimer transitioned from daily investing activities in 2021 and now dedicates much of his time to Athens, his wife's hometown, where his children cherish their Greek passports. He presented himself for our interview in a casually rumpled button-down shirt and jeans, a contrast to the polished quarter-zips and fine knitwear often favored by his peers. Despite his shift in focus, Index Ventures has continued to achieve exceptional returns, having raised approximately $15 billion from external investors since its inception, with last year's exits, including Figma's IPO and Google's acquisition of the cybersecurity firm Wiz, reportedly generating around $9 billion for the firm.
Rimer has actively engaged in philanthropic endeavors. He serves on the board of Endeavor Greece, an organization that mentors entrepreneurs in emerging markets, and chaired the board of Human Rights Watch from 2019 to 2025. In late 2021, he, along with his father and two brothers, contributed $13 million to McGill University for the renovation of a campus building, now known as the Rimer Building, and the establishment of a new Institute for Indigenous Research and Knowledges.
His remarks on redistribution emerge at a notably challenging period for charitable giving. The Giving Pledge, initiated by Warren Buffett and Bill Gates in 2010 to encourage billionaires to commit half their fortunes to philanthropy, is increasingly losing its relevance. A March report from The New York Times highlighted this trend, noting that 113 families signed the pledge in its first five years, followed by 72, then 43, and a mere four in all of 2024, underscoring a decline in philanthropic engagement among some of the wealthiest individuals in tech. As the piece pointed out, "Elon Musk, the world’s wealthiest person, has said that his businesses ‘are philanthropy.’"
This pattern of declining generosity extends beyond the Pledge itself. While total American charitable giving reached a record $592.5 billion in 2024, the number of Americans participating in donations has fallen for five consecutive years, dropping by 4.5% in 2024 alone, according to the Stanford Social Innovation Review. In 2000, two-thirds of households donated; today, roughly half do. Data from Bank of America and the Lilly Family School further indicates that even giving among affluent households has decreased, from 90% in 2017 to 81% last year.
The trend is also evident within Index's own investment portfolio, which includes Anthropic. Business Insider recently questioned financial planner Alex Caswell about whether his newly affluent clients, many of whom are Anthropic employees aligned with effective altruism principles, were committing to donate a significant portion of their wealth. Caswell confirmed that while Anthropic matches employee donations of up to 25% of their equity to charity, and some clients utilize this, most are not integrating philanthropy into their long-term financial plans. Instead, their focus is predominantly on angel investing or launching their own ventures. "That’s what I’m seeing more than the desire to become philanthropic," he told the publication.
Predictably, the diminished scope of voluntary giving is now leading to legislative efforts to mandate wealth redistribution. California voters will soon decide on a proposed 5% one-time wealth tax targeting the state's billionaires. In anticipation, some prominent figures, including Google founders Sergey Brin and Larry Page, have already relocated their primary residences to South Florida for tax planning purposes.
OpenAI is reportedly considering a public offering in 2027, and one speculative, albeit cynical, reason for this timing could be related to the potential California wealth tax. If passed, the tax would calculate net worth based on an individual’s worldwide assets as of the end of the current calendar year.
Equally unsurprising is the significant opposition to any large-scale wealth redistribution measures. This includes Governor Gavin Newsom and economists who highlight that numerous industrialized nations have repealed similar wealth taxes since 1990 after observing their wealthy residents relocate.
Other proposed solutions are equally contentious. OpenAI has reportedly discussed offering the federal government a 5% equity stake, an idea CEO Sam Altman has presented as a way to share AI’s economic benefits with the public. Critics, however, view it as a strategic move to secure political favor in Washington. In either scenario, Silicon Valley has historically been reluctant to include Uncle Sam as a stakeholder. Veteran investor Roelof Botha lightheartedly remarked during a separate conversation last year, "Some of the most dangerous words in the world are: ‘I’m from the government, and I’m here to help.’"
It is important to consider the vast amount of wealth that exists outside these proposed mechanisms. Following SpaceX’s IPO last month, Elon Musk's net worth surpassed $1 trillion, making him the first individual to reach this milestone. Forbes' 2026 rankings alone identified 45 new AI billionaires, collectively worth $2.9 trillion, and this figure precedes the potential public offerings of Anthropic or OpenAI. The aforementioned Business Insider article on Anthropic employees noted that once Anthropic and OpenAI complete their IPOs, their combined employees could hold sufficient wealth to purchase nearly a third of all homes in the San Francisco metropolitan area.
While the current concentration of wealth feels unprecedented, whether it constitutes a historical extreme remains a subject of debate. The share of wealth held by the top 1% of U.S. households reached 31.7% in the third quarter of last year, a record since the Federal Reserve began tracking this data in 1989, and roughly equivalent to the combined wealth of the other 90% of households outside the top decile.
This figure is still below the 45% commanded by the top 1% at the peak of the Gilded Age in 1916. However, when the focus narrows to the very wealthiest individuals, the picture shifts dramatically. Renowned economist Gabriel Zucman calculates that around 1910, at the height of the Gilded Age, America’s four largest fortunes combined represented 4% of U.S. GDP. Today, that same sliver of the population—now encompassing 19 households instead of four—accounts for a staggering 14% of GDP.
Rimer’s two proposed paths, voluntary or compelled, find historical parallels from the previous era when American wealth concentration reached similar levels. In 1889, at the apex of the first Gilded Age, Andrew Carnegie published his seminal essay, "The Gospel of Wealth." In it, he argued that a wealthy individual should regard their fortune as a trust to be distributed for the public good during their lifetime, famously declaring it a "disgrace to die wealthy." This essay became a foundational text for modern philanthropy and the intellectual precursor to initiatives like the Giving Pledge.
However, Carnegie’s vision of voluntary redistribution did not long deter the emergence of the alternative path. By the mid-1930s, Louisiana Senator Huey Long had garnered a national following with his "Share Our Wealth" program, which advocated for steep taxes on the rich to fund a guaranteed income for every American. Concerned about losing working-class support to Long, Franklin Roosevelt enacted what the press dubbed the "soak-the-rich tax," which elevated the top marginal income tax rate to as high as 79%. While it redistributed less than Long had demanded, it remains the clearest historical example in America of politically mandated redistribution arising when voluntary giving proved insufficient to alleviate mounting societal pressures.
None of these historical precedents are new to Rimer, who has spent his entire career in the tech sector. What he finds more intriguing is "the moral center of tech companies," a fascination he traces back to his time as a Stanford undergraduate in 1984. He recalls how Apple offered discounted first-generation Macintoshes to students, and how Steve Jobs and other Apple founders were, in his words, "heroes" for creating something he genuinely believed was beneficial for the world.
What troubles him now, he stated, is hearing his own children discuss certain tech companies in a manner reminiscent of how an earlier generation spoke about defense contractors or cigarette manufacturers.
Critics might rightly point out that Rimer, as an investor in Anthropic and other tech ventures, is a direct beneficiary of the very windfall he believes will ultimately need to be shared. However, his preference is for his fellow beneficiaries to proactively choose to return some of that wealth, rather than having it forcibly taken from them. He posits that there is an easy way and a hard way to achieve this, and Rimer is banking on individuals opting for the easy path before historical forces dictate the harder one for them.
