Who holds the trillions: the most expensive companies in the world in 2026
In 2026, the ranking of the world's most valuable companies by CompaniesMarketCap increasingly resembles a list of the largest players in technology and artificial intelligence. Among the leaders are chip manufacturers, cloud platform developers, and companies that are actively investing in AI. It is important to note that high market capitalization does not mean that a company is the most profitable or generates the highest revenue: the indicator reflects how much investors are willing to pay for its shares at the moment.
NVIDIA
NVIDIA remains the world’s largest public company by market capitalization, exceeding $5 trillion. The main driver of the company’s growth is the demand for graphics processing units and the infrastructure required to train and deploy modern AI models.
Initially, NVIDIA was primarily known as a manufacturer of video cards, but today its business is much broader. The company supplies computing accelerators, networking equipment, and software solutions for data centers. It is precisely the investment boom surrounding artificial intelligence that has made NVIDIA one of the biggest winners in recent years.
Apple
Apple holds the second place with a market capitalization of approximately $4.5 trillion. The company maintains its enormous market value thanks to its ecosystem of devices and services — from iPhones and Macs to the App Store, iCloud, and other digital products.
Apple remains one of the world’s most valuable brands, and its market position is supported by a massive user base and high customer loyalty. Meanwhile, investors closely monitor how actively the company will be able to integrate artificial intelligence into its products.
Alphabet
Google’s parent company, Alphabet, ranks third with a market capitalization of around $4.3 trillion. The core of Alphabet’s business still consists of its search engine and advertising ecosystem, but Google Cloud and AI-related initiatives are gaining increasing importance.
Alphabet is simultaneously developing its own AI models, data centers, and infrastructure to support them. Therefore, the company competes not only with other internet giants but also for a share of the rapidly growing AI infrastructure market.
Microsoft
Microsoft holds the fourth position with a market capitalization of approximately $3.7 trillion. The company generates revenue from several major segments — software, the Azure cloud platform, enterprise services, and gaming products.
Artificial intelligence plays a separate and crucial role in Microsoft’s strategy. The company integrates AI tools into products for businesses and developers, while also actively expanding the cloud infrastructure necessary to run these models.
Amazon
In recent years, Amazon has increasingly moved beyond traditional online retail. The main driver of the company’s growth is Amazon Web Services — the largest cloud computing segment, which is actively used for AI workloads.
Due to stock price fluctuations, Amazon may rank above or below the $3 trillion mark depending on the specific day, so its position in rankings varies across different dates.
TSMC
Taiwan Semiconductor Manufacturing Company, or TSMC, is the world’s largest contract semiconductor manufacturer. Its market capitalization exceeds $2 trillion.
Unlike NVIDIA or Apple, TSMC is not a brand that most users see every day. However, the company produces a significant portion of the most advanced chips for the technology market. Its factories produce processors and accelerators that are then used in smartphones, computers, data centers, and AI systems.
The growing interest in artificial intelligence directly impacts TSMC as well: the more powerful chips companies require, the higher the demand for advanced manufacturing capacity.
Broadcom
Broadcom specializes in semiconductors and infrastructure software. The company has become one of the notable beneficiaries of the artificial intelligence boom thanks to its solutions for data centers and network infrastructure.
According to CompaniesMarketCap, Broadcom’s market capitalization is around $2 trillion, allowing the company to rank among the largest public companies in the world.
Its growth highlights an important trend: the AI market generates revenue not only for developers of popular neural networks. Huge demand is forming around the equipment, networks, and other components needed to build data centers.
SpaceX
SpaceX holds a high position in the ranking due to the sharp increase in the company’s valuation amid investor interest in space technologies, satellite communications, and artificial intelligence. According to CompaniesMarketCap, in August 2026, SpaceX’s market capitalization was valued at approximately $1.7 trillion, allowing the company to enter the list of the ten most valuable companies in the world.
SpaceX differs from most companies on the list because its valuation is not formed through daily stock trading on a public exchange. CompaniesMarketCap uses the company’s estimated value and calculates the metric based on available data about its shares.
Saudi Aramco
Saudi Aramco is the largest oil and gas company in Saudi Arabia and one of the most valuable public companies in the world. Its market capitalization is around $1.7 trillion, placing it ninth in the global ranking.
Unlike most of the ranking’s leaders, Saudi Aramco represents the traditional energy sector. The company is engaged in exploration, production, refining, and sales of oil and gas, while also developing initiatives in petrochemicals and energy.
Saudi Aramco went public in 2019, but the government of Saudi Arabia still owns the vast majority of the company. Therefore, its presence in the ranking demonstrates that high market value is maintained not only by technology corporations and companies associated with artificial intelligence.
Meta Platforms
Meta Platforms remains one of the world’s largest technology holdings. Its ecosystem includes Facebook, Instagram, WhatsApp, and other products. Its market capitalization is approximately $1.5 trillion.
The company is simultaneously investing billions of dollars in artificial intelligence, developing its own models and computing infrastructure. AI is used in content recommendations, advertising, generative tools, and other Meta products.
Tesla
Tesla remains one of the world’s most valuable automotive companies, although its valuation is significantly broader than that of a traditional automaker. According to CompaniesMarketCap, in August 2026, Tesla’s market capitalization was around $1.2 trillion.
Beyond electric vehicles, investors are evaluating Tesla’s prospects in autonomous driving, robotics, energy storage systems, and artificial intelligence.
This is why the company’s value cannot be directly compared with traditional automakers: a significant portion of Tesla’s valuation is tied to expectations regarding future technological directions.
Berkshire Hathaway
Berkshire Hathaway differs from most companies on this list. It is not a technology giant, but a holding company with businesses in insurance, energy, rail transportation, manufacturing, retail, and other sectors.
In August 2026, Berkshire Hathaway’s market capitalization was approximately $1.1 trillion. The company remains one of the largest public businesses in the world, demonstrating that the technology sector is not the only path to a trillion-dollar valuation.
Samsung
Samsung’s market capitalization was approximately $1 trillion as of August 2026.
Samsung Electronics operates in several technology segments simultaneously. The company produces semiconductors, DRAM and NAND memory, SSDs, televisions, smartphones, and other electronics. It is precisely the combination of chip business and consumer electronics that makes Samsung one of the largest technology manufacturers in the world.
Why there are so many technology companies in the ranking
The main feature of the current ranking is the enormous influence of artificial intelligence. The top of the list is dominated by companies that either directly produce AI technologies or provide the infrastructure for their operation.
NVIDIA supplies computing accelerators, TSMC produces advanced chips, Microsoft and Amazon are expanding cloud platforms, and Alphabet and Meta are creating their own AI models and products.
At the same time, the growth in market capitalization reflects not only current financial results. Investors are valuing companies’ future earnings, so stock prices can fluctuate significantly even before new technologies begin to generate substantial revenue.
