The venture capitalist and Social Capital founder laid out his case in a June 10, 2026 thread on X, criticizing Anthropic’s practice of evaluating user prompts against its own internal safety and policy standards before deciding whether to generate output. He called it an “idiotic risk” for enterprises, arguing that a model that reserves the right to simply decline work introduces a reliability problem most businesses can’t afford. This wasn’t abstract theorizing. Palihapitiya’s frustration traces back to a hands-on experiment he ran on May 16, 2026, when he fed the same stock screening prompt to four leading AI models: Claude, Grok, Gemini, and ChatGPT. Three of the four returned results. Claude refused. Palihapitiya’s core argument is that Anthropic’s design philosophy produces more refusals than its competitors. He flagged two specific dangers. The first is model lock-in, where companies that build deeply integrated systems around Claude find it increasingly expensive to switch providers when the refusal rate becomes intolerable. The second is loss of control over output generation, where Anthropic’s internal standards, not the customer’s needs, ultimately determine what the model will and won’t do. His proposed solutions were pragmatic. Companies should either implement what he called “control planes,” essentially middleware layers that can route prompts to alternative models when one refuses, or consider shifting to open-source AI models where the organization itself sets the policy boundaries. This isn’t Palihapitiya’s first time questioning Anthropic’s approach to safety. Back in April 2026, when Anthropic released warnings surrounding the Claude Mythos Preview, he dismissed the company’s safety communications as “theater” and “crying wolf.” **Disclosure:** This article was edited by Editorial Team.
