Largest tech companies in the world: the top 29 by revenue from their own filings

This list is for people who sell to technology companies: chip and hardware suppliers, contract manufacturers, software and security vendors, recruiters, agencies and service firms. It ranks the 29 largest tech companies in the world by revenue from each company's own filing, shows Big Tech and the largest US tech companies separately, and explains where the buying happens inside companies this size.

The 29 largest tech companies by revenue

Revenue is the top line of each company's latest annual report published by 30 October 2026: Form 10-K or 20-F for SEC filers, the audited annual report for Huawei, the reviewed 2025 financial statements for Samsung, the annual results announcements filed in Hong Kong for Tencent and Xiaomi, and the full-year results releases for Foxconn, Lenovo and SK hynix. Dollar conversions use the Federal Reserve's 2025 annual average rates (G.5A, released 5 January 2026): NT$31.1663, KRW 1,421.3963, CNY 7.1875 and ¥149.5686 per dollar, and $1.1306 per euro. The change is in each company's reporting currency. Employees are as each report states them, at year-end.

A few rows need a note:

• Fiscal years differ by up to a year. Micron's year ran to 3 September 2026 and caught most of the rise in memory prices; Samsung's and SK hynix's calendar 2025 caught less. That timing, as much as anything, is why Micron's growth (+256%) is so far ahead of SK hynix (+47%) and Samsung (+11%).
• Foxconn's figure is rounded. Its FY2025 results release gives revenue only as NT$8.1 trillion, up 18%, so the conversion is approximate.
• Huawei is private but publishes an audited annual report. It converts at the year-end rate (CNY 6.9906) and shows $126.0 billion; at the 2025 average rate it's $122.6 billion, just ahead of TSMC.
• Xiaomi is counted as a device maker, but its total includes CNY 106.1 billion from its smart EV, AI and other new initiatives segment, mostly cars.
• Sony excludes its financial services business, which it separated in a partial spin-off during the year; its ¥12.48 trillion is sales to external customers.
• Headcounts are defined differently. Apple counts full-time equivalents, TSMC full-time employees, Jabil includes temporary and contingent workers, and IBM's 273,000 adds 264,300 at wholly owned subsidiaries to 8,700 at less-than-wholly-owned ones (it lists another 13,800 complementary workers separately).

Big Tech: the Magnificent Seven by revenue

"Big Tech" usually means Alphabet, Amazon, Apple, Meta and Microsoft; the "Magnificent Seven" adds NVIDIA and Tesla. Two of them, Amazon and Tesla, fall outside the ranking above because most of their revenue comes from retail and cars.

Amazon's 10-K splits its $716.9 billion: online stores $269.3 billion, third-party seller services $172.2 billion, physical stores $22.6 billion, AWS $128.7 billion, advertising $68.6 billion and subscriptions $49.6 billion. The three retail lines are 65% of the total. AWS on its own would rank ninth in the main table, between Micron and Huawei. If you count all of Amazon as a tech company, it's the largest by revenue.

The largest tech companies in the US

Eighteen of the 29 are headquartered in the US, and they reported $2.38 trillion of the list's $3.63 trillion in revenue. In order: Apple, Alphabet, Microsoft, NVIDIA, Meta, Micron, Dell, IBM, Oracle, Broadcom, Cisco, HP, Intel, Qualcomm, Salesforce, Jabil, AMD and Hewlett Packard Enterprise. Add Amazon and it moves to the top. For software alone, see the largest software companies; for headcount at one company, the profiles of NVIDIA and Microsoft go year by year.

How we built the list

1. Who counts. Companies whose main business is semiconductors, computers and devices, contract electronics manufacturing, software and cloud, ad-funded internet platforms or IT services. Left out: retailers and marketplaces (Amazon, Alibaba), carmakers (Tesla), ride-hailing and delivery (Uber), streaming (Netflix), appliance and industrial groups (Hitachi, LG Electronics, Midea, Panasonic) and electronics distributors such as TD Synnex ($62.5 billion in its year to November 2025).
2. What's counted. Total revenue as reported, including every consolidated subsidiary. We opened each filing or report rather than relying on tagged data.
3. Which year. The latest full year each company had reported by 30 October 2026. We don't annualize quarters, so Apple's year to September 2026, which it hadn't filed yet, isn't used.
4. Currencies. Reported figure first, then dollars at the 2025 average rate. Sony and Lenovo's years ended March 2026, so their conversion is an approximation.
5. Not ranked. The Taiwanese server makers Quanta and Wistron publish results, but we couldn't open their 2025 reports when we checked, so they aren't in the table. Check them before assuming they fall below the $34.3 billion cut. Private companies that don't publish results aren't here.

What the top results get wrong. The Wikipedia list of tech companies by revenue, taken from Fortune's Global 500, still shows Microsoft at $281.7 billion, its year to June 2025; Microsoft's 10-K for the year to June 2026 reports $331.8 billion. The same page shows Dell with 108,000 employees, while Dell's latest 10-K says about 97,000. WorldAtlas, another top result, still carries Apple at $229.2 billion, a figure from 2017. Market-value rankings change daily: the 10-K covers put the stock held by non-affiliates at about $4.0 trillion for NVIDIA on 25 July 2025 and about $3.25 trillion for Apple on 28 March 2025, and neither is a current value.

What the list is good for if you sell B2B

Group the list by how each part buys. This is general guidance, not taken from any one company's policies:

Use the headcount breakdowns to find the budget. Microsoft's 10-K splits its 223,000 full-time staff into 89,000 in operations (including datacenter operations), 77,000 in research and development, 43,000 in sales and marketing and 14,000 in general and administration. NVIDIA has about 31,000 of its 42,000 people in research and development. Cisco's sales and marketing functions have about 25,400 employees. Each group has its own budget.

Watch where the people are going. TSMC's North America headcount rose from 2,668 at the end of 2023 to 5,290 at the end of 2025, and Japan's from 804 to 2,447. A new site brings local spending on construction, maintenance, staffing, housing and services before it brings chip revenue. Our guide to enterprise account research shows how to turn a filing into a one-page account brief; at volume, Bebop does that research for each account in a list.

Worked example

Illustrative example. Reviewly (reviewly.example) sells an AI code review tool for $30 per developer per month. Its account executive sizes three accounts from the research and development headcounts in their 10-Ks, treating every R&D employee as a possible seat (an upper bound, since not all of them write code):

• Microsoft: 77,000 x $30 x 12 = about $27.7 million a year.
• NVIDIA: 31,000 x $30 x 12 = about $11.2 million a year.
• Broadcom: 57% of about 33,000 employees work in research and development, about 18,800 people: 18,800 x $30 x 12 = about $6.8 million a year.

None of them will buy for every engineer first. A realistic opening is one product group of 400 developers: 400 x $30 x 12 = $144,000 a year, small enough for an engineering director's budget. The account executive targets that director, runs a 60-day pilot on one codebase, and uses the full-deployment figure only to show what a rollout is worth.

Next step: see how the same companies compare once you divide revenue by headcount, in companies with the highest revenue per employee.
