Let's look at it from another perspective. It's not uncommon for tech companies to be valued at around a PE ratio of 30. This would mean a company worth 300bn should make about 10bn in profit each year. Chatgpt's usage is as ubiquitous as products that make 100's of billions in profit such as google search and instagram, does the valuation really seem that insane? OpenAI just needs to open the ad flood gates and suddenly no one is laughing anymore.
