How the biggest companies in the market actually make their money—and what investors should know about each one.
Key Takeaways
- Each Mag 7 company has a distinct business model and revenue engine.
- Diversification varies widely—from Tesla’s focus on autos to Microsoft’s cloud and software empire.
- Investors should understand where each company’s profits come from—and what parts are still growing.
- Big bets on AI, cloud computing, and hardware ecosystems drive future potential.
The Magnificent Seven, a group of seven top tech stocks, may collectively move markets, but they make money in very different ways. Understanding each company’s business model can help you see what drives their earnings—and where the next stage of growth might come from.
Apple: The Hardware-to-Services Ecosystem
Founded in 1976 and headquartered in Silicon Valley, Apple (AAPL) is most well known for its iPhone, a touchscreen mobile device first released in 2007 and credited with ushering in a “smartphone revolution.” Other popular Apple products include the Mac (personal computer), iPad (tablet), and Apple Watch (smartwatch).
That said, a growing share of Apple’s revenue comes from its related advertising, cloud, digital content, and payment services. In fiscal year 2025, services made up 26.23% of Apple’s revenue, up from 24.59% in 2024 and 22.23% in 2023. Many of these services require a subscription, allowing Apple to turn hardware buyers into long-term customers.
Microsoft: Software, Subscriptions, and Cloud
Microsoft (MSFT) is a software behemoth founded by Bill Gates in 1975. Its core business is licensing Windows, the popular computer operating system, and Office 365, a suite of productivity tools.
However, the company also offers a computing service called Azure, which drives its long-term growth and profit margins. According to the company's latest 10-K filing, server products and cloud services revenue increased 23% from fiscal year 2024 to 2025.
Meanwhile, the company also owns these brands (among others):
- LinkedIn, a social network for business professionals
- Xbox, a gaming console and service
- Surface, a personal computer and accessories line
- Microsoft Edge and Bing, an internet browser and search engine
Microsoft’s recurring revenue model from these software services is one of the most diversified among the Magnificent Seven.
Amazon: Retail Giant to Cloud Powerhouse
Amazon (AMZN) went from selling books to becoming the world’s top online retailer. In Q3 2025, the company’s North America net sales increased 11% year-over-year to $106.3 billion. Meanwhile, sales from its International segment increased 14% to $40.9 billion.
Even though e-commerce is Amazon’s core revenue driver, it’s not the company’s fastest-growing segment. Today, AWS (Amazon Web Services) is a leading cloud computing platform. It generated $33 billion in net sales in Q3 2025, representing a 20% increase from the same period last year. In short, while retail drives Amazon’s scale, AWS drives its profit.
Alphabet: The Ad Machine and AI Pivot
Alphabet (GOOG) is the parent company of Google, the world’s foremost search engine, founded in 1998. Since then, it has branched out to offer many other digital services and products, including:
- Android, a smartphone operating system
- Chrome, a web browser
- Gmail, an email provider
- Maps, a navigation app
- Play Store, a digital app store
- YouTube, an online video platform
All seven Google products have two things in common: They make money primarily through ad revenue, and they have each been integrated with Google’s new AI model Gemini. This reflects the company’s mission to make its tools more helpful to users. Bottom line: Alphabet is funding its bets on AI with ad cash flow from its internet services.

Magnificent 7 Stocks: What You Need To Know
Meta: Ads and the Metaverse
Meta (META), formerly Facebook, is the most popular social media network worldwide with about 2.9 billion monthly active users. To make money, the company sells advertising to third parties. However, Meta doesn’t just own the Meta social media platform. It also owns Instagram, Messenger, and WhatsApp—all of which also generate revenue through advertising.
Meanwhile, the company has been investing in the development of AI and virtual reality (VR) technologies. Its “Reality Labs” segment offers VR hardware, such as the Oculus headset, and software, such as the Metaverse. However, Reality Labs only accounted for 1.3% of Meta’s revenue in 2024. To grow this segment, Meta must keep its social media users engaged.
Nvidia: The AI Hardware Backbone
Nvidia (NVDA) is one of the hottest companies and stocks right now. In February 2024, its market capitalization jumped by $272 billion, the largest increase ever seen in a single day. And the company’s value is still growing.
This is largely due to the company dominating the sales of GPUs (graphic processing units) for AI applications and data centers. What started as a GPU manufacturer for video games has become the top GPU manufacturer for the AI boom.
According to the company’s latest 10-K filing, “The GPU was initially used to simulate human imagination, enabling the virtual worlds of video games and films. Today, it also simulates human intelligence, enabling a deeper understanding of the physical world.”
Tesla: Cars, Energy, and Scale
Led by Elon Musk, Tesla (TSLA) is the world’s largest automaker by market capitalization. The company designs, develops, manufactures, sells, and leases high-performance fully electric vehicles (EVs) and energy generation and storage systems.
While the company’s automotive segment makes up nearly 80% of its revenue, all of its products focus on sustainable energy, providing long-term upside as consumers and governments continue to favor eco-friendly energy solutions.
How Do the Magnificent 7 Make Most of Their Money?
Apple generates most revenue from iPhone sales and services. Microsoft earns primarily through cloud computing (Azure) and software subscriptions. Amazon’s largest revenue source is online retail, though AWS delivers the higher profit margins. Alphabet relies overwhelmingly on advertising across Google Search, YouTube, and its other platforms. Meta generates nearly all revenue from ads on Facebook, Instagram, and WhatsApp. Nvidia makes money selling GPUs for AI data centers and gaming. Tesla earns the majority of its revenue from electric vehicle sales.
Which Magnificent 7 Company Has the Most Diversified Business Model?
Microsoft has the most diversified business model among the Magnificent Seven. The company generates revenue across various segments, including cloud computing (Azure), productivity software (Office 365), operating systems (Windows), professional networking (LinkedIn), gaming (Xbox), hardware (Surface), and search (Bing). This spans enterprise, consumer, and developer markets with multiple recurring revenue streams.
How Much Does Each Rely on AI for Future Growth?
All seven companies view AI as critical to their future growth, but their dependence on it varies. Nvidia is most directly tied to AI, with its GPUs powering the AI boom. Microsoft and Alphabet are heavily investing in AI to enhance their cloud and software businesses. Meta is betting on AI to enable its metaverse vision. Amazon uses AI to optimize operations and AWS services. Apple is integrating AI into devices and services. Tesla relies on AI for developing autonomous driving technology.
The Bottom Line
While each of the Magnificent Seven has a slightly different business model, they share a common story: dominance through scale, innovation, and recurring revenue. Understanding how each company earns—and reinvests—its money can help you gauge which business models may lead the next phase of market growth.
