Microsoft has overtaken Apple for the first time since 2021 to become the world’s most valuable firm by market capitalisation – which measures the value and number of a company’s shares.
Microsoft surpassed Apple at numerous points throughout Thursday’s trading on the New York Stock Exchange (NYSE) when its value reached $2.87trn and Apple shares fell by 1%.
But Apple reclaimed the top spot as the trading day wore on.
This latest movement comes on the back of a major investment in artificial intelligence (AI) by Microsoft.
It’s the largest backer of OpenAI, the company behind the game-changing generative AI chatbot ChatGPT.
AI is also being embedded into Microsoft products such as its Bing search engine.
