How risky is Microsoft and Nvidia’s stranglehold?

Microsoft and Nvidia have quickly taken prime positions in the artificial intelligence revolution. The tech giants have a combined market value of $6.6 trillion (€6.16 trillion), making them two of the three largest companies in the world.

Microsoft’s recent success has been underpinned by its $13 billion bet on OpenAI, the startup behind the ChatGPT chatbot, while Nvidia can boast the world’s most advanced chips that are vital to running high-end AI systems.
