Alphabet owns Google (which includes Android, Chrome, and YouTube), Nest (home automation), Calico (anti-aging research), Fiber (high-speed Internet), Google Ventures (new company investments), Sidewalk Labs (city infrastructure), and Waymo (driverless cars). Other services include Google Maps, Google Play, AI, and cloud computing.

Alphabet is investing huge amounts of money in AI, which has weighed on its share price. The company expects to spend between $195 billion and $205 billion on capital expenditures in 2026, driven overwhelmingly by technical infrastructure for artificial intelligence.

Alphabet spent $45 billion in the second quarter alone, double the amount spent during the same period in 2025. SEC filings indicate that Alphabet has committed an additional $811 billion in future spending, largely earmarked for AI infrastructure.

Alphabet is using artificial intelligence to power its core consumer products, scale enterprise cloud services, and build massive underlying computing infrastructure. For example, Alphabet is embedding its Gemini AI model across Android devices, cars, TVs, watches, and core apps like Google Search and YouTube.

Amazon.com remains a global leader in e-commerce and cloud computing, with its Amazon Web Services (AWS) division driving significant growth and innovation. The company’s scale and technology investments continue to set it apart in retail, logistics, and digital services.

Nvidia is now the primary engine behind the global artificial intelligence revolution. It provides the essential chips, software platforms, and data centre infrastructure required to build and run modern AI systems.

Nvidia pioneered programmable GPUs using its “CUDA toolkit”, a programming platform that allows computer chips to handle the massive simultaneous calculations needed to train neural networks. The company is also building “AI Factories” in partnership with tech giants like OpenAI and Amazon Web Services.

That’s not all. Nvidia is working on physical AI platforms (i.e., robots) that allow them to learn and make decisions in real world environments.

Apple is an international technology company headquartered in Cupertino, California. It is one of the largest companies in the world, with a market cap of $4 trillion.

Apple mainly uses AI to enhance the performance of Siri, its conversational search device. An enhanced version of Siri was unveiled earlier this month, but critics say it lacks the power and functionality of competing products.

The company has not invested in AI on the same scale as some of the other major players. The money it has spent is focused on acquisitions of smaller companies with the patents and skills to improve its own products. One of its largest deals, in February of this year, was the purchase of Israeli start-up Q.ai for between $1.6 billion and $2 billion. Q.ai specializes in machine learning that interprets speech through audio and subtle facial cues.

Microsoft is a leading technology conglomerate whose business is defined by three main segments: Intelligent Cloud, Productivity and Business Processes, and More Personal Computing.

 

The company has successfully transitioned its core identity from a PC software provider to a powerhouse in cloud computing, driven by its Azure platform and the integration of AI across its product suite, especially Copilot and the new Agent 365 framework. This shift has established Microsoft as a central player in the enterprise market, with a highly sticky and recurring revenue model that delivers strong operating margins. The firm is currently investing heavily in AI infrastructure to meet burgeoning demand, particularly through its deepened partnership with OpenAI and its “Foundry” AI platform
