As the artificial intelligence (AI) market continues to grow, there are many AI stocks for investors to choose from on top exchanges like the NASDAQ, TSX and ASX.
AI technology has made strong inroads into several key industries, including logistics, manufacturing, finance, healthcare, customer service and cybersecurity.
The technology has been around for a long time, but this current wave of buzz comes after the release of OpenAI’s ChatGPT, a generative AI platform. This intelligent chatbot shows how quickly generative AI is advancing, and it has led to many other major tech firms entering the space with their own generative AI offerings or including AI technology into their innovative products.
On a global scale, Fortune Business Insights predicts that the AI industry will experience a compound annual growth rate of 29.2 percent between 2025 and 2032 to reach a market value of more than US$1.77 trillion.
American AI stocks
According to Tracxn Technologies, the number of US AI companies has more than doubled since 2017, with over 84,950 companies working in the sector today.
One of the major factors fueling growth in the American AI market, states Statista, is “the growing investments and partnerships among technology companies, research institutions, and governments.’
Below are three of the top US AI stocks by market cap. For more US AI stocks, check out our list of 12 generative AI stocks and 5 AI ETFs.
