Xiao-I shares surge 52.90% premarket after China's Supreme People's Court upholds validity of core AI patents in lawsuit against Apple.

Xiao-I Corporation surged 52.90% in premarket trading following a key legal development in its patent infringement lawsuit against Apple. On March 27, 2026, China’s Supreme People’s Court rejected Apple’s appeal to invalidate the AI-related patents held by Xiao-I’s variable interest entity, confirming their full validity. This ruling, which is final and binding under Chinese law, strengthened Xiao-I’s legal position and signaled a potential advantage in the ongoing litigation. The decision was widely reported and framed as a setback for Apple and a validation of Xiao-I’s intellectual property, likely driving the sharp premarket price increase as investors reacted to the positive legal outcome.
