Andrew Chen, a general partner at a16z, discussed the commercial potential of ChatGPT on social media. Chen noted that OpenAI's ChatGPT has reached a staggering scale of more than 200 million users per week in just a few years. He raised several questions worth pondering: Has anyone analyzed ChatGPT's per capita search and per-impression revenue? How might a business like ChatGPT perform if it adopted a Google-like ad monetization model? Chen believes that some products with a similar user base, such as the Firefox browser, had annual revenue approaching $1 billion at their peak. If ChatGPT were free to use, its MAU users could increase significantly. He said that large language model (LLM) products have the potential to be disruptors in the search business and could achieve considerable monetization. Chen also pointed out that it is worth considering whether LLM will increase overall search volume or simply take market share from existing search engines such as Google.
