Nvidia earned its $2.2 trillion market cap by producing artificial-intelligence chips that have become the lifeblood powering the new era of generative AI developers from startups to Microsoft, OpenAI and Google parent Alphabet.

Almost as important to its hardware is the company’s nearly 20 years' worth of computer code, which helps make competition with the company nearly impossible. More than 4 million global developers rely on Nvidia's CUDA software platform to build AI and other apps.

Now a coalition of technology companies that includes Qualcomm, Google and Intel plans to loosen Nvidia’s chokehold by going after the chip giant’s secret weapon: the software that keeps developers tied to Nvidia chips. They are part of an expanding group of financiers and companies hacking away at Nvidia's dominance in AI.
