What is the most expensive AI stock?

Could you please elaborate on which aspect of AI stocks you are specifically referring to when asking about the most expensive? Are you inquiring about the highest market capitalization, the highest share price, or perhaps the company with the most expensive valuation per share? It's essential to clarify, as these metrics can vary significantly and impact the answer to your question. For instance, a company with a high market capitalization may not necessarily have the highest individual share price, and vice versa. Additionally, valuing AI stocks can be complex, as many factors contribute to their pricing, such as revenue, growth potential, and industry trends.
