Richtech Robotics claimed a Microsoft partnership. It was a free customer program.
Richtech Robotics claimed a Microsoft partnership. It was a free customer program.
On January 27, 2026, Richtech Robotics issued a press release announcing a hands-on collaboration with Microsoft through its AI Co-Innovation Labs, describing a joint effort to develop and deploy agentic AI capabilities in real-world robotic systems. CEO Wayne Huang said the collaboration reflected a shared focus on applying advanced AI to practical, real-world use cases.
The stock surged 36 percent that day, according to Reuters data, reaching $5.18 — the steepest single-day gain in just over a year.
The next morning, Richtech announced a $38.7 million dilutive at-the-market private placement of 8.5 million Class B common shares.
On January 29, Hunterbrook Media published its investigation: Microsoft told the outlet the engagement was a standard customer program with no commercial element. The AI Co-Innovation Labs, according to Microsoft's own description, offers one-week complimentary development sprints available to any customer or startup that applies.
The stock dropped over 20 percent.
Multiple securities class actions have since been filed against Richtech, including suits from Hagens Berman, Levi & Korsinsky, Block & Leviton, Berger Montague, Rosen Law, Kirby McInerney, and Holzer, among others. Hagens Berman's complaint accuses the company of misleading investors about the nature of its Microsoft relationship in order to execute the dilutive equity raise. The complaint calls it a possible new variant of AI washing — a pump-and-dump play dressed up in partnership language.
The most damaging evidence against Richtech may be its own. In a 10-K filed over a week before the January 27 press release, Richtech described the Microsoft engagement as a non-commercial technology collaboration. The press release called it a close collaboration involving joint development and deployment.
Disclosing one thing to the SEC and the opposite to the market is not a PR misstep. It is a legal exposure.
Richtech Robotics makes the ADAM robot, an AI-driven beverage-serving system deployed in hospitality environments. It is a real company with real robots. But the gap between its press release language and its own regulatory filings suggests that its public claims about AI capabilities and partnerships were calibrated for the stock price rather than accuracy.
The robotics industry has a partnership-hype problem. When every small company can claim access to the same big-tech AI labs, naming Microsoft or Google or OpenAI in a press release becomes a form of currency rather than news. Richtech appears to have tested how far that currency could be stretched before someone checked.
The lead plaintiff deadline is April 3, 2026. The SEC has not publicly commented on Richtech.
Hunterbrook Media, which broke the Microsoft denial, is a short-seller research firm. It disclosed at time of publication that it holds a short position in RR and long positions in comparable securities. Its financial interest does not alter the core facts: Microsoft said the engagement was not commercial, the stock dropped on that disclosure, and Richtech's own filings contradict its public language.
