Artificial intelligence (AI) may be an emerging technology, but there are plenty of billion-dollar companies in this space.

As the market has grown over the past few years, AI technology has made strong inroads into several key industries, including logistics, manufacturing, finance, healthcare, customer service and cybersecurity.

While AI-driven advancements in robotics have received the most press in recent years, the latest buzz has centered around OpenAI’s ChatGPT. This intelligent chatbot shows how quickly generative AI is advancing, and has attracted the attention of heavyweight technology companies such as Microsoft (NASDAQ:MSFT), which has reportedly invested billions of dollars in the privately held OpenAI. Alphabet (NASDAQ:GOOGL) has also released its own AI chat tool, Google Gemini.


On a global scale, Fortune Business Insights predicts that the AI industry will experience a compound annual growth rate of 20.2 percent between 2024 and 2032 to reach a market value of more than US$2.74 trillion.

Here the Investing News Network profiles some of the biggest AI stocks by market cap on US, Canadian and Australian stock exchanges. Data was gathered on April 12, 2024, using TradingView’s stock screener.

American AI stocks

According to Tracxn Technologies, the number of US AI companies has more than doubled since 2017 with over 70,700 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.

1. Microsoft (NASDAQ:MSFT)

Company Profile

Market cap: US$3.134 trillion; share price: US$421.74

In addition to the reported billions Microsoft is committed to investing in OpenAI, the technology behemoth has built its own AI solutions based on the chatbot creator’s technology: Bing AI and Copilot. OpenAI officially licensed its technologies to Microsoft in 2020.

An update to Windows 11 in 2023 integrated Bing into the operating system's search bar, allowing users to interact with the chatbot directly with Microsoft's Edge browser, Chrome and Safari.

Microsoft’s moves into generative AI have translated into higher revenues for its Azure cloud computing business, and a higher market capitalization as the tech giant pushed past the US$3 trillion mark in January 2024. The company is also expected to unveil its first AI PC this year.

2. NVIDIA (NASDAQ:NVDA)

Company Profile

Market cap: US$2.215 trillion; share price: US$866.11

The global leader in graphics processing unit (GPU) technology, NVIDIA is designing specialized chips used to train AI and machine learning models for laptops, workstations, mobile devices, notebooks, and PCs. The company is partnering with a number of big name tech firms to bring a number of key AI products to market.

Through its partnership with Dell Technologies (NYSE:DELL), NVIDIA is developing AI applications for enterprises, such as language-based services, speech recognition and cybersecurity. The chip maker has been instrumental in the build out of Meta Platforms’ (NASDAQ:META) AI supercomputer called the Research SuperCluster, which reportedly uses a total of 16,000 of NVIDIA's GPUs.

Most recently, NVIDIA and the Taiwan Semiconductor Manufacturing Company (NYSE:TSM) have developed the world's first multi-die chip specifically designed for AI applications: the Blackwell GPU. Blackwell’s architecture allows for the increased processing power needed to train larger and more complex AI models.

NVIDIA’s AI ambitions were on full display at its GPU Technology Conference in March where CEO Jensen Huang presented his company’s plans to build humanoid robots, known as Project GR00T. “Building foundation models for general humanoid robots is one of the most exciting problems to solve in AI today,” stated Huang in his keynote presentation.

3. Alphabet (NASDAQ:GOOGL)

Company Profile

Market cap: US$1.967 trillion; share price: US$158.92

Alphabet holds court with both Microsoft and NVIDIA as part of the tech sector’s Magnificent 7, and its foray into AI has also brought the tech giant much success. As of April 12, Alphabet’s market cap looks set to surpass the US$2 trillion mark.

It would seem investors still remain confident in the potential for growth in Alphabet’s AI ventures despite its hiccups in the rollout of its subsidiary Google’s AI chatbot Gemini, formerly called Bard. “While the headlines haven’t been favorable, Google’s role in generative AI products will present massive growth opportunities for the stock,” said Sylvia Jablonski, chief executive officer at Defiance ETFs.

In early April, Google introduced a custom AI chip designed for its cloud services customers. Set to be delivered later this year, the technology uses British semiconductor company Arm Holding's (NASDAQ:ARM) AI architecture. In the same week, Google revealed its new A3 Mega AI processor based on NVIDIA’s H100 Technology.
