Founded in 1975, Microsoft is well versed in hardware and software. Its hardware lineup consists of its flagship Surface brand, which is a competitor for Microsoft’s archrival Apple and its iPad Pros and MacBooks.

The company’s software portfolio has always been a strong focus. That includes its computer operating system, where Microsoft's Windows 11 debuted in Q4 2021, as well as its Windows Server. Furthermore, Microsoft has been targeting business users with its productivity suite, which includes the Office and Cloud platforms. These, along with its Azure platform, which includes machine learning and AI, have become major revenue generators for the tech giant.

Early last year, Microsoft announced "a multiyear, multibillion dollar investment" in privately held OpenAI to help the AI research lab with ChatGPT, its ultra-powerful AI chatbot. In April, the company announced plans to invest US$1.5 billion in United Arab Emirates-based AI tech holding company G42. The collaboration will see G42 run its AI applications and services on Microsoft Azure so the partners can deliver advanced AI solutions to clients. The partnership also includes establishing advanced AI and digital infrastructure in the Middle Eastern, Central Asian and African regions.

NVIDIA, the inventor of the graphics processing unit (GPU), creates interactive graphics on laptops, workstations, mobile devices, notebooks, PCs and more. Alongside GPUs, NVIDIA offers processing capabilities to scientific researchers with supercomputing sites across the globe. The primary arms of NVIDIA’s business model are in gaming (including its cloud gaming service GeForce Now), automotive electronics, mobile devices and more recently AI.

The company’s major competitors are Advanced Micro Devices (NASDAQ:AMD), Intel (NASDAQ:INTC) and Qualcomm (NASDAQ:QCOM). NVIDIA is working with Meta Platforms (NASDAQ:META) to build the latter’s AI supercomputer, which the former expects will be the largest NVIDIA DGX A100 customer system to date.

The company is also working with Dell Technologies (NYSE:DELL) on more AI offerings for enterprises, including the new Dell AI Factory. "AI factories are central to creating intelligence on an industrial scale," said NVIDIA founder and CEO Jensen Huang in a March press release. "Together, NVIDIA and Dell are helping enterprises create AI factories to turn their proprietary data into powerful insights."

Founded in 1994, Amazon has evolved from its start as an online retailer to become a tech monolith through its Amazon Web Services (AWS) platform. While Amazon is still a dominant force in web-based sales, AWS offers a broad range of services for computing, storage, databases, networking, analytics, machine learning and AI, among others. Furthermore, Fire TV, Amazon’s streaming platform, had sold more than 200 million streaming devices worldwide as of March 2023.

Amazon's Internet of Things (IoT) service, called AWS IoT FleetWise, allows automakers to collect, transform and transfer vehicle data to the cloud in near-real time more efficiently and cost effectively than was previously available. The data can then be organized and standardized for analysis in the cloud.

AWS' Q4 2023 revenue was US$24.2 billion, up 13 percent from the same quarter the previous year. This growth pattern over the past few years has allowed AWS to crack an annualized revenue run rate of US$100 billion.

Tesla is one of the world’s most influential tech companies. Aside from focusing on the electric vehicle (EV) market, the company is also innovating in AI, robotics, autonomous vehicles and energy storage. The company has a partnership with Panasonic (OTC Pink:PCRFF,TSE:6752) to produce lithium-ion batteries for its EVs.

Tesla’s EV sales grew by more than 37 percent in 2023 over the previous year to reach more than 1,808,590 units delivered. Still, Tesla's market cap lost nearly 17 percent of its value from April 17, 2023 to April 17, 2024. Several market factors are responsible for the decline decline, including an expected drop in EV sales as a global recession sets in.
