Big Technology • 8506 implied HN points • 03 Feb 26
🕹 Technology Mobile Apps

How Many People Does It Take to Kill a ChatGPT?

The Algorithmic Bridge • 414 implied HN points • 04 Mar 26
🕹 Technology Mobile Apps
  1. The QuitGPT boycott caused a big spike in uninstalls and helped Anthropic’s Claude grab attention, but millions leaving are a tiny fraction of ChatGPT’s ~900 million weekly users and a negligible hit to OpenAI’s revenue.
  2. ChatGPT was already losing market share to competitors like Claude, Google’s Gemini, and Grok, and enterprise customers have shifted significantly toward Anthropic.
  3. Social-science tipping-point research implies you’d need roughly 25% of users (about 225 million) to flip to truly topple a dominant platform, so individual cancellations and the current boycott are far from decisive, though enterprise losses, talent drains, and funding risks still threaten OpenAI.

How Anthropic Can Win in Consumer

🕹 Technology Mobile Apps
