Quick answer: 1. NVIDIA, 2. Apple, 3. Alphabet (Google), 4. Microsoft, 5. Amazon, 6. TSMC (Taiwan Semiconductor Manufacturing), 7. SpaceX, 8. Broadcom, 9. Saudi Aramco, 10. Meta Platforms.
Market capitalization — a company's share price multiplied by its shares outstanding — is the simplest yardstick for how the public market values a business at a given moment. This list ranks the ten most valuable public companies in the world as of July 5, 2026, drawn from live market-cap trackers and cross-checked against reference data. The 2026 top tier is dominated by U.S. technology firms riding AI-driven demand, with NVIDIA, Apple, and Alphabet each clearing $4 trillion. It also captures two notable shifts: TSMC and Saudi Aramco carry the list's only non-U.S. flags, and SpaceX debuts at No. 7 after its record June 2026 IPO. Because share prices move continuously, these figures are a point-in-time snapshot rather than a live scoreboard.
The world's most valuable public company, NVIDIA's market cap climbed past $4.7 trillion as demand for its AI accelerators reshaped the semiconductor market.
A long-time market-cap leader, Apple now sits second at roughly $4.53 trillion, its consumer-electronics franchise still among the most valuable on Earth.
The parent of Google and YouTube ranks third; combining its Class A and Class C share classes values it near $4.35 trillion.
Microsoft's Azure cloud platform and enterprise-software business anchor a market cap near $2.9 trillion.
Amazon's e-commerce operation and AWS cloud arm together value the company around $2.6 trillion.
The world's leading chip foundry and the highest-ranked non-U.S. company on the list, TSMC is valued near $2.25 trillion.
Fresh off a June 12, 2026 IPO — the largest offering in history — SpaceX debuts as the seventh most valuable public company at roughly $2.13 trillion.
Broadcom's AI networking chips and infrastructure software lift its market cap to roughly $1.71 trillion.
The only oil company and only Middle Eastern firm in the top 10, Saudi Aramco is valued near $1.68 trillion.
Parent of Facebook, Instagram, and WhatsApp, Meta edges out Tesla for the tenth spot at roughly $1.48 trillion.

Companies are ranked by market capitalization in U.S. dollars — the latest share price multiplied by total shares outstanding — as reported on July 5, 2026. Only publicly traded companies are eligible; state-owned or privately held firms that do not trade on a public exchange are excluded. Each distinct company is counted once: where a firm has multiple share classes (for example, Alphabet's Class A and Class C), their values are combined into a single market cap. Figures are expressed in USD trillions and sourced from live market-capitalization trackers (CompaniesMarketCap.com and StockTitan), cross-referenced against Wikipedia's reference list and, for SpaceX's IPO, CNBC reporting. Ranking is strictly descending by market cap; because equity prices fluctuate continuously, the order reflects the stated snapshot date only.
As of the July 5, 2026 snapshot used for this list, NVIDIA is the most valuable public company by market capitalization, at roughly $4.72 trillion — ahead of Apple and Alphabet. Market caps change continuously with share prices, so this reflects that date, not a live figure.
Market capitalization equals a company's current share price multiplied by its total number of shares outstanding. For companies with multiple share classes, such as Alphabet, the classes are combined into a single figure.
Two: TSMC (Taiwan Semiconductor Manufacturing), based in Taiwan and ranked sixth, and Saudi Aramco, based in Saudi Arabia and ranked ninth. The other eight are U.S.-headquartered.
SpaceX completed its initial public offering on June 12, 2026 — reported as the largest IPO in history — which made it a publicly traded company. On this snapshot date it ranked seventh, at roughly $2.13 trillion.
