Exclusive: China's DeepSeek trained AI model on Nvidia's best chip despite US ban, official says

Chinese AI firm DeepSeek allegedly accessed and used Nvidia's top-tier, banned Blackwell chips for model training. This suggests that despite the US export ban, demand for Nvidia's high-end chips remains strong and they are still reaching the Chinese market through unofficial channels. This could imply that revenue forecasts, which may have discounted the Chinese market, are too low. Conversely, it highlights the geopolitical risk and the potential for stricter enforcement or future crackdowns. The situation presents a mixed signal. While it confirms the superiority and high demand for Nvidia's products, it also underscores the ineffectiveness and potential blowback of US sanctions, creating uncertainty. The stock should be monitored for developments. The US government could tighten enforcement, penalize Nvidia or its partners, or accelerate sanctions, negatively impacting sentiment and future sales. China could achieve self-sufficiency faster than expected, eroding Nvidia's long-term market share.
