After three and a half years since its launch, ChatGPT has for the first time in its history seen its share of the global AI assistant market drop below 50%. This was revealed in the Sensor Tower report titled "State of AI 2026", published by TechCrunch.

However, this decline has not prevented ChatGPT from setting a new record, becoming the first app to reach one billion monthly users in such a short time. This paradoxical trend highlights the dynamic and competitive nature of the AI market, where even a loss in market share does not negate successful growth in popularity.
