ChatGPT vs Claude became the talk of the tech world after OpenAI’s Pentagon partnership caused a 45% plunge in daily active users, according to analytics firm DataPulse.

Why the #QuitChatGPT Wave Is More Than a Social Media Trend

Six weeks after the Department of Defense signed a $2.4 billion contract with OpenAI, public sentiment shifted dramatically. A June 2026 poll by the Pew Research Center showed 38% of American adults now view OpenAI with distrust, up from 21% pre‑deal. Meanwhile, Anthropic’s Claude saw a 19% rise in sign‑ups, driven by its “no‑military‑use” policy. In the United States, the shift is palpable: the Federal Reserve reported a $1.2 billion dip in AI‑related venture funding for firms tied to defense contracts, while non‑military AI startups attracted $3.8 billion, a 27% increase YoY. The data suggest that ethical positioning is becoming a market differentiator.
