Nvidia's 'one line' has led to almost 500% jump in this technology company's stock, biggest single-day surge of 2025 on Wall Street

Cyngn Inc, a little-known industrial robotics company, has captured Wall Street’s attention with a staggering 483% single-day stock surge on Thursday (June 26), skyrocketing from $5 to over $29.25 in just 15 minutes of trading. The catalyst? A subtle nod from

Nvidia CEO Jensen Huang

in a developer blog post that sent trading volume soaring past 44 million shares -- exceeding the stock’s entire 2025 volume combined. The frenzy began Tuesday when Nvidia’s blog highlighted Cyngn as a key player among robotics innovators using its AI-powered

Nvidia Isaac platform

for safe, scalable automation in dynamic environments.

What is the Nvidia deal all about

The mention, part of a press release during the Automatica 2025 robotics event, marked Cyngn’s first appearance on Nvidia’s official site. While the market initially slept on the news, momentum built late Wednesday, erupting into Thursday’s explosive rally. The collaboration highlights how Cyngn is leveraging the Nvidia Isaac robotics platform to power next-generation autonomous vehicle solutions for industrial applications. “Cyngn Inc. today announced its collaboration with Nvidia as part of the Automatica 2025 robotics and automation showcase. As featured in NVIDIA’s recent blog post, Cyngn was selected among a handful of robotics innovators using NVIDIA Isaac technologies to accelerate safe, scalable autonomy across dynamic, real-world environments.”Cyngn, based in Mountain View, California, specializes in its DriveMod technology, which transforms industrial vehicles like forklifts and tuggers into autonomous mobile robots (AMRs) capable of handling loads up to 12,000 pounds. Requiring no infrastructure changes, DriveMod targets warehouses, factories, and outdoor industrial zones, offering cost-effective automation solutions. The company’s integration of Nvidia Isaac enhances its robots’ ability to make real-time decisions in complex settings, earning it credibility as a robotics “leader” in Nvidia’s eyes.

From 100% drop in stock to 500% jump

This sudden spotlight contrasts sharply with Cyngn’s struggles. The company, public since 2021, reported just $368,000 in revenue for 2024 and $47,000 in Q1 2025, missing analyst estimates for four consecutive quarters. Its stock plummeted 100% over the past year, narrowly regaining Nasdaq compliance in March 2025 after failing to meet the exchange’s minimum bid price. Yet, Thursday’s rally propelled Cyngn’s market cap above $35 million, driven by what traders call Nvidia’s “halo effect”—a phenomenon previously seen with stocks like Navitas Semiconductor, which surged after joining Nvidia’s supply chain.
