Mizuho Securities estimates that Nvidia controls between 70% and 95% of the market for AI chips used for training and deploying models like OpenAI's GPT. Nvidia's position in the AI chip market has been described as a moat by some experts. Founded in 2019, D-Matrix plans to release a semiconductor card for servers later this year that aims to reduce the cost and latency of running AI models. "Nobody can deny that today Nvidia is the hardware you want to train and run AI models," Fernando Vidal, co-founder of 3Fourteen Research, told CNBC. "The key is that there are a lot of options there," Su told reporters in December, when her company launched its most recent AI chip.
