A widening rift between Anthropic and the startup ecosystem threatens to undermine the AI company's standing just months before a potential IPO that could generate $15 billion in annual philanthropic giving.
Anthropic, the AI safety company co-founded by seven former OpenAI employees, is facing mounting distrust from Silicon Valley startup founders and researchers over its competitive tactics, restrictive guardrails, and refusal to support open-weight models.
"There was no governance, oversight, or accountability" for AI systems as they began to spin out of control, Ryan Carrier, founder of the nonprofit ForHumanity, said. His organization, which develops tools for auditing AI systems, has raised just hundreds of thousands of dollars since 2016.
The backlash comes as Anthropic prepares for an IPO that could value the company at nearly $2 trillion alongside OpenAI, according to a tech industry insider's estimates. The listing, which could occur as soon as September, may result in $15 billion a year in additional philanthropic giving alone — enough to boost total US giving by about 2.5 percent annually, the equivalent of adding four Bill Gates-level donors. Anthropic's seven founders have pledged to donate 80 percent of their wealth, and the company has agreed to match employee donations at one or three shares for every one committed.
The distrust threatens Anthropic's ability to attract talent, secure partnerships with other tech startups, and maintain its reputation as the ethical alternative to OpenAI — a positioning central to its brand since its founding in 2021. With Meta's Llama and Mistral gaining traction as open-weight alternatives, Anthropic risks losing relevance in the segment of the market that values transparency and community collaboration.
Competitive tactics draw scrutiny
The criticism centers on three fronts. Startup founders say Anthropic has used its relationships with venture capital firms to discourage funding for companies building on rival open-weight models, according to people familiar with the discussions. Researchers have accused the company of implementing guardrails that go beyond safety and into competitive moat-building — restricting how third-party developers can use Claude, its flagship model, in ways that limit interoperability with competing platforms. Anthropic has also been among the most vocal opponents of open-weight AI models, lobbying Washington against open-source approaches alongside OpenAI, according to a report.
The lobbying effort puts Anthropic at odds with a significant portion of the developer community. More than 1,000 employees at America's leading AI companies, including senior staff and co-founders at OpenAI, Anthropic and Google DeepMind, recently signed a statement asking the US government to support international efforts to "deliberately pace" cutting-edge automated AI development — a position that stops short of the outright opposition to open models that Anthropic has privately advocated.
The $15B philanthropy question
The IPO windfall has created a secondary dynamic: nonprofits are jockeying for a share of the expected giving wave. Jack Lewars, a consultant who advised 13 ultrarich tech and finance workers on charitable giving last year, said employees at AI labs are receiving as many as 20 unsolicited emails a week from groups seeking donations. Organizations including AI4ALL, GiveDirectly, and Animal Charity Evaluators are ramping up hiring, training, and automation to position themselves to absorb the influx.
But some nonprofits worry the money will flow disproportionately to causes favored by effective altruists — such as existential risk from AI — while leaving human rights and social justice organizations underfunded. Marlena Wisniak, who oversees digital strategy at the European Center for Not-for-Profit Law, has been trying to raise the profile of overlooked groups, particularly in the global south. She scored a victory this month when a friend at Anthropic donated $100,000 to one such organization.
Investor implications
For investors, the backlash introduces uncertainty into what has been one of the most anticipated tech IPOs in history. Anthropic's valuation, like OpenAI's, depends partly on its ability to maintain premium pricing for its closed models relative to open-weight alternatives. If the developer community shifts further toward Meta's Llama or Mistral, Anthropic's pricing power could erode. The company declined to comment on the total amount its employees have set aside to donate and the organizations that may benefit.
