Microsoft became the world’s most valuable publicly traded company by market capitalization in 2024 after passing Apple.
Microsoft moved ahead of Apple in January 2024 as investors responded to strong enthusiasm for artificial intelligence and Microsoft’s expanding cloud business. Its partnership with OpenAI and integration of AI features across products helped focus attention on its potential role in the AI economy.
The ranking was not permanent. Apple and Microsoft repeatedly exchanged the top position as their share prices changed, and Nvidia also became a leading contender during the 2024 technology-stock rally. Market-cap rankings are snapshots rather than fixed titles.
Microsoft’s diversified business includes Azure, Office, Windows, LinkedIn, Xbox, and advertising. Apple remains primarily associated with consumer hardware, although services have become an increasingly important part of its revenue and business strategy.
