AI War 2026: ChatGPT vs Gemini vs Claude

AI War 2026: ChatGPT vs Gemini vs Claude — Which Should You Use? #

Updated February 2026 with the latest market data.

The artificial intelligence market has changed dramatically. In 2023, ChatGPT dominated with 87% market share. Today, in 2026, that number has dropped to around 68%. Google's Gemini jumped from a mere 5% to over 18%. And Anthropic's Claude carved out a solid niche among developers and professional writers.

The question everyone asks: which AI should I use?

The honest answer: it depends on what you need to do.

Let's break down each one.
