Neil Rimer, co-founder of Index Ventures, predicts that the wealth AI is generating will have to be redistributed. “It’ll either be voluntary or it’ll be involuntary, but it’ll happen, and I hope it’s voluntary,” Rimer told TechCrunch at a tech festival in Athens.
The statement carries weight because of who is making it. Index Ventures has raised roughly $15 billion from outside investors since its founding, and last year’s exits, including Figma’s IPO and Google’s acquisition of Wiz, reportedly netted the firm approximately $9 billion, according to TechCrunch.
The Giving Pledge Problem
Rimer’s comments arrive as voluntary philanthropy among tech’s wealthiest is declining. The Giving Pledge, Warren Buffett and Bill Gates’ initiative to get billionaires to commit half their fortunes to charity, attracted 113 families in its first five years. That figure dropped to 72, then 43, then just four in all of 2024, TechCrunch reported, citing a New York Times analysis.
Total American charitable giving reached a record $592.5 billion in 2024, but the number of Americans actually giving has fallen for five straight years, down 4.5% in 2024 alone, per Stanford Social Innovation Review data cited by TechCrunch. Two-thirds of households donated in 2000. Roughly half do now.
The pattern extends into Index’s own portfolio. Business Insider reported that Anthropic employees, many tied to effective altruism, are largely not building philanthropy into their financial plans. A financial planner working with newly wealthy Anthropic staff told Business Insider that most clients are focused on angel investing or starting companies, not charitable giving, according to TechCrunch.
The Involuntary Option
Without voluntary action, the involuntary version is already materializing. California voters will decide this year on a 5% one-time wealth tax targeting the state’s billionaires. Some, including Google founders Sergey Brin and Larry Page, have already moved their primary residences to South Florida, TechCrunch reported.
OpenAI, reportedly considering a 2027 IPO, may be factoring the tax into its timeline: the California wealth tax, if passed, would calculate net worth based on worldwide assets as of the end of this calendar year, creating an incentive to go public before the assessment date, according to TechCrunch.
The Capital Allocation Question
For the agent ecosystem, Rimer’s prediction has concrete implications. AI wealth redistribution, whether through taxation, regulation, or philanthropic pressure, would redirect capital flows currently concentrated in a small number of companies and their employees. If California’s wealth tax passes, it could raise tens of billions from AI billionaires alone, potentially funding public AI infrastructure, education, or workforce transition programs that create new markets for agent platforms and automation tools.
Rimer stepped back from day-to-day investing at Index in 2021 and now spends much of his time in Athens, where his wife is from. He chaired the board of Human Rights Watch from 2019 to 2025 and in 2021 gave $13 million to McGill University, TechCrunch noted. His track record suggests the prediction is informed by conviction, not performance.
