Some companies have become so valuable that their market capitalisation is easier to discuss in trillions than billions. Their products may be ordinary parts of a day: a phone, a search, a supermarket visit or a payment. The ownership claims on those businesses are anything but ordinary in scale.
Market capitalisation gives those claims a common measuring stick. It combines a share price with the number of shares outstanding. This table ranks the hundred largest values in the captured source, making a snapshot of the businesses that public markets value most highly.
Trillion-dollar companies
Companies worth US$1tn or more when this list was captured on 12 September 2026: NVIDIA, Apple, Alphabet (Google), Microsoft, Amazon, TSMC, SpaceX, Broadcom, Saudi Aramco, Meta Platforms (Facebook), Tesla, Samsung, Micron Technology and Berkshire Hathaway.
The share price is only half the calculation
A company with an expensive individual share is not necessarily larger than one with a cheap share. The number of shares matters. A stock split can reduce the price of each share while leaving the value of the company’s equity broadly unchanged at that instant. Market capitalisation helps avoid that misleading comparison.
Different businesses, one measure
Technology, finance, energy and consumer businesses earn money in different ways. A common equity-value ranking does not make their balance sheets interchangeable. Revenue measures sales, profit measures what remains after relevant costs, and assets measure resources on a balance sheet. None of those is the number being ranked here.
The limits of a public-market map
Private companies are outside this comparison. A state can own most of a listed company while only a smaller proportion trades freely. Multiple share classes, overseas listings and exchange-rate conversion can also affect how a data provider assembles its total. We retain the provider’s company records rather than adding separate listings together ourselves.
What this snapshot shows
NVIDIA leads this captured list at approximately US$5.27tn. The entry at number 100, QUALCOMM, is approximately US$194.35bn. The first ten account for 46.1% of the sum of the hundred reported values. That share is calculated within this list; it is not a share of the entire economy.
The first ten
NVIDIA
Listing symbol: NVDA ·
NVIDIA made its name by supplying the graphics processors that draw game worlds. The same ability to perform many calculations in parallel opened a much larger role in scientific computing and artificial intelligence. Its business now connects chips, networking, complete computing systems and the software used to work with them.
The striking part of its position is that much of this technology sits inside another organisation’s infrastructure. A consumer may never buy an NVIDIA-branded device yet still use services running on its processors.
Apple
Listing symbol: AAPL ·
Apple combines hardware, operating systems and services in products intended to work together. The iPhone is its most recognisable example, but Macs, iPads, watches and the services surrounding them extend the relationship beyond a single purchase. The company’s origins in personal computing remain visible in that integration of product and software design.
Its market value prices the whole business, including expectations about future products and services. It is not the retail value of the devices already in customers’ pockets or on their desks.
Alphabet (Google)
Listing symbol: GOOG ·
Alphabet was created in 2015 as the parent of Google and a wider collection of businesses. Search and advertising are central to its economic story, while YouTube, Android and cloud services give it several other routes into people’s working and everyday lives.
The listed parent is the unit being valued here. Google’s familiar name helps readers identify the company, but the number represents Alphabet’s equity as a whole, including activities that a user of the search engine may rarely encounter.
Microsoft
Listing symbol: MSFT ·
Microsoft’s history runs from software for early personal computers to the infrastructure of modern offices and data centres. Windows and Office made the brand familiar, while Azure, business applications, developer tools and gaming expanded its reach into other settings.
Its place in the ranking reflects that combination of established software relationships and newer computing demand. A company can buy Microsoft services throughout its organisation, from an employee’s desktop to the systems delivering its own products to customers.
Amazon
Listing symbol: AMZN ·
Amazon’s storefront is the most visible part of a business that also supplies cloud computing, advertising, entertainment and logistics. The online bookseller founded in 1994 grew into a marketplace where outside merchants sell alongside Amazon’s own retail operations.
Amazon Web Services adds a different kind of customer relationship: organisations pay for computing infrastructure rather than physical products. That combination is why a retail-sector appearance should not be mistaken for a valuation of the shopping website alone.
TSMC
Listing symbol: TSM ·
TSMC manufactures semiconductors for other companies. Its foundry model lets customers design chips while relying on a specialist manufacturer to turn those designs into physical devices. The precision, factories and process development required make this a very different business from selling a branded phone or computer.
Its position reveals an important link between apparently separate technology companies. Competing products can depend on the same manufacturer, and demand for advanced computing reaches TSMC through the designs its customers ask it to build.
SpaceX
Listing symbol: SPCX ·
SpaceX connects launch vehicles, spacecraft and satellite communications in one enterprise. Falcon rockets and Dragon spacecraft made reusable launch operations and transport to orbit central parts of its identity, while Starlink created a communications business supported by a large satellite network.
The hardware is dramatic, but the underlying businesses are different: launching a customer’s payload and providing a broadband connection create distinct revenue relationships. The source’s market-capitalisation figure values the listed company as a whole, rather than one rocket programme or satellite constellation.
Broadcom
Listing symbol: AVGO ·
Broadcom supplies semiconductors and infrastructure software used inside networks, data centres, storage systems and connected devices. Its products often work behind more recognisable consumer or enterprise brands, moving data or supporting the systems that organisations rely on.
The acquisition of VMware added a substantial software business to that mix. Broadcom’s appearance alongside device makers therefore represents a different part of the technology economy: components and infrastructure that help other companies deliver their own products and services.
Saudi Aramco
Listing symbol: 2222.SR ·
Saudi Aramco’s operations connect the production of oil and gas with processing, refining and related industrial activity. Based in Dhahran, it is closely tied to Saudi Arabia’s petroleum resources and remains majority state-owned. Its scale comes from operating a vast physical energy system.
The market-capitalisation measure values the company’s shares, including shares that are not freely traded. It should not be confused with the size of the public float, the annual value of oil sold or a direct price for all the oil underground.
Meta Platforms (Facebook)
Listing symbol: META ·
Meta brings Facebook, Instagram, WhatsApp and other communication services under one parent. The company’s advertising business links the attention of users with organisations trying to reach them. Those services differ in format, but their scale gives the group several ways to build and maintain an audience.
Its spending on artificial intelligence and immersive computing sits alongside that established business. The valuation belongs to the parent company, so the ranking does not assign a separate market price to each individual app.
The ranking continues: 11–100
