Grok, Elon Musk's AI chatbot, has seen a meteoric rise in market share, jumping from 1.6% to 15.2% among daily U.S. users of chatbot apps in just one year. However, Grok's growth has been fueled by controversial features, including the ability to generate explicit images, even of minors, upon request. The app's user base is also overwhelmingly male, and Grok has been designed to cater to this demographic, including an anime AI companion that engages users in sexual fantasies.

Why it matters

Grok's rapid growth and controversial features raise concerns about the ethics and implications of the AI chatbot race. As leading AI companies like OpenAI and xAI (Musk's company) compete to gain market share and prepare for public offerings, there are fears that the pressure to sustain user engagement and growth could lead to the normalization of potentially harmful or unethical AI features.

The details

Grok's market share surge coincided with news that the bot would generate explicit images of people, including minors, upon request. This download spike took the app from around 500,000 daily downloads in late December to close to 1 million in early January. Over the past six months, 82% of Grok's weekly active users have been male, compared to 49.9% for ChatGPT, 45% for Gemini, and 77.8% for Claude. Grok has built features to specifically attract this male-dominated audience, including an anime AI companion that engages users in sexual fantasies. Some xAI employees have reportedly signed waivers acknowledging their work would expose them to 'sensitive, violent, sexual and/or other offensive or disturbing content'.

  • In January 2026, Grok's market share jumped from 12.0% to 15.2%.
