This list ranks the ten most valuable technology companies, the corporate superpowers that define the 21st century.

(Note: Valuations are based on market capitalization as of September 2025 and are subject to constant fluctuation due to market volatility.)

Methodology

This ranking is based on market capitalization (market cap) as of September 2025. Market capitalization is calculated by multiplying the total number of outstanding shares by the current stock price. This figure represents the total market value of a company's outstanding shares and is the most common metric for determining a company's overall value.

Data Sources:

• Real-time stock market data and financial exchanges
• Official company financial reports and SEC filings
• Verified financial databases and market data providers
• Company investor relations materials

Important Considerations:

• Market capitalization fluctuates constantly with stock price movements
• Tech companies are particularly volatile due to rapid innovation cycles
• AI and emerging technology trends significantly impact valuations
• Currency fluctuations can affect international comparisons
• Rankings can shift dramatically based on market conditions, product launches, and regulatory changes
