DeepSeek AI’s Disruption Shakes Markets and Sparks U.S. Security Crackdown

Dana Suheil


DeepSeek AI, a Chinese artificial intelligence startup, has quickly emerged as one of the most disruptive forces in the tech industry, sending shockwaves through both financial markets and U.S. national security discussions. Its chatbot, launched just last month, became the most downloaded app in the United States almost overnight. What set DeepSeek apart was not just its accessibility but its efficiency, offering AI capabilities that rival, and in some cases surpass, those of American firms at a fraction of the cost. Investors reacted swiftly, triggering a major selloff in the tech sector. Nvidia, which supplies high-performance AI chips, saw its stock plunge 17%, erasing roughly $600 billion in market value in a single day. Other tech giants, including AMD, Broadcom, and Oracle, also suffered significant declines, with the Nasdaq Composite shedding over 3% as panic spread across Wall Street. The fear wasn’t just about competition but about the realization that DeepSeek had achieved remarkable AI advancements using Nvidia’s more affordable H800 chips, raising concerns that U.S. firms could lose their competitive edge in the AI arms race.



While the financial markets grappled with DeepSeek’s sudden rise, lawmakers in Washington were already sounding alarms over its potential national security risks. Representatives Darin LaHood and Josh Gottheimer introduced a bipartisan bill to ban the chatbot from government-owned devices, citing concerns that its software contained hidden code capable of transmitting user data to China Mobile, a state-owned telecom company that has long been banned from operating in the U.S. “This should be a no-brainer in terms of actions we should take immediately to prevent our enemy from getting information from our government,” said Gottheimer, emphasizing the urgency of the issue (Andrews 2025). The proposed legislation mirrors previous efforts to limit Chinese tech influence, particularly the restrictions placed on TikTok due to fears that American user data could be accessed by the Chinese government. In this case, cybersecurity analysts have reinforced those fears, with Ivan Tsarynny, CEO of Feroot Security, warning that DeepSeek’s software is actively collecting user data and sending it to China. “Our personal information is being sent to China, there is no denial, and the DeepSeek tool is collecting everything that American users connect to it,” he said (Andrews 2025).



DeepSeek’s growing presence has not only unsettled U.S. officials but also prompted global responses. Australia, South Korea, and Italy have all moved to block the app from government systems, signaling a broader international push to prevent Chinese AI firms from gaining access to sensitive data. The Chinese Foreign Ministry has pushed back against these allegations, calling the U.S. response an overreaction and asserting that China legally protects data privacy. However, skepticism remains, especially as DeepSeek’s model continues to raise red flags among cybersecurity experts who view it as a potential espionage tool disguised as an open-source innovation.



As the U.S. government moves forward with potential restrictions, the debate over DeepSeek highlights a much larger issue—how artificial intelligence is becoming a key battleground in the ongoing technology war between the United States and China. If DeepSeek’s breakthroughs are as substantial as some reports suggest, it could mark a pivotal moment in the AI industry, challenging the dominance of U.S. tech firms and forcing a reassessment of American AI strategies. The coming months will determine whether DeepSeek’s rise is a temporary disruption or a fundamental shift in the balance of power in artificial intelligence. Either way, its impact has already been felt, from Wall Street to Washington, and the fight over AI regulation is just beginning.
