Is OpenAI, its ChatGPT service, taking market share from Google? Well, maybe. Rand Fishkin of Sparktoro posted his assumptions based on a mix of data from SimilarWeb and Datos that says ChatGPT's current market share is 4.33% - that is from October 2024 data.
But… they aren’t even really in the same market. There’s some overlap, sure, but not entirely.
This is laughable.
