Going long on AI stocks is fairly hard. OpenAI, Antrophic, and xAI are privately held, as are most of the robotics companies and companies. Companies like Amazon, Google, or Tesla might are sort of AI investments, but they are just subsidiaries or small fractions of the parent (Zoox, Waymo, FSD, etc).

This isn't quite like the dot-com era, with tons of pure play investment options avaialable, regardless of whether you want to go long or short.
