The Financial Times reported that OpenAI's annual revenues exceeded US$2 billion in December thanks to the overwhelming success of its flagship artificial intelligence product ChatGPT, which has made it one of the fastest growing technology firms in history.

According to CEO Sam Altman, 92% of Fortune 500 companies were using OpenAI products last November, and the chatbot boasts 100 million weekly users. Despite this, the company is still showing losses due to the significant costs associated with developing and operating its models. Expenses are expected to continue to outpace revenue growth as OpenAI develops more sophisticated models. Several competitors are also entering the market with their AI products, including tech giants such as Google and Meta, and start-ups such as Anthropic, Mistral and Cohere. For example, Google recently introduced its new Gemini AI system, which is available to users through a premium subscription priced at $20 per month.

The enthusiasm for artificial intelligence has led to a rise in stocks across the technology sector, but Microsoft has benefited from this trend exceptionally well. Since January 2023, when Microsoft invested in OpenAI, its stock has risen approximately 70%, leading to an increase in the company's market value of more than $1.2 trillion. However, some investors are expressing concern about a possible bubble, as it is still uncertain how much additional revenue the AI boom will bring to these companies.
