Chinese AI startup DeepSeek has invested 140.8 million yuan – approximately $20.8 million – in robot maker Unitree’s Shanghai initial public offering, receiving 933,399 shares representing a 2.31% stake through the IPO’s strategic placement. The two companies, both headquartered in Hangzhou, have simultaneously announced a partnership to jointly develop AI models for humanoid robots.
Under the agreement, Unitree will give preference to DeepSeek when procuring model-training services and technical solutions. DeepSeek will similarly favour Unitree when purchasing robots or exploring embodied AI applications. The arrangement creates a mutual dependency that aligns each company’s commercial interests with the partnership’s success.
Why This Partnership Makes Sense for Both Companies
DeepSeek has established itself as one of the most capable and cost-competitive AI model providers in the world, with strong performance on coding, mathematics, and reasoning benchmarks. But its strengths have been concentrated in language models rather than multimodal systems capable of processing vision alongside text. DeepSeek has released separate vision-language research models including VL2, but these remain outside its flagship commercial offering. A DeepSeek researcher briefly published work in April on improving visual reasoning through points and bounding boxes before the paper and GitHub repository were withdrawn without explanation.
The Unitree partnership addresses a structural gap: DeepSeek needs robots and physical-world interaction data to develop embodied AI capability, and Unitree needs AI models that can close the gap between walking, dancing humanoids and robots capable of reliably understanding unfamiliar environments and turning instructions into physical actions.
For Unitree, the partnership brings one of the most capable AI reasoning teams in China to work on the specific problem that limits humanoid commercial utility – the robot brain, not the body. China has developed relatively inexpensive humanoid hardware capable of impressive locomotion, but useful autonomous work requires models trained on scarce physical-world data: demonstrations of object manipulation, door opening, clothes folding, and adaptive response to changing environments. Unitree is already operating data-collection facilities where humans guide robots through such tasks; DeepSeek’s model development capability could accelerate the conversion of that data into deployable intelligence.
The IPO Context
Unitree is expected to be valued at more than 50 billion yuan following its Shanghai STAR Market listing, according to sponsor Citic Securities. The company reported first-half 2026 revenue of approximately 1.1 billion yuan, up 35-45% year-on-year, and plans to use the 4.2 billion yuan raised to expand R&D and production. DeepSeek’s strategic placement investment makes it a publicly declared partner of Unitree at the moment the company enters public markets – a signal about the direction of both companies’ physical AI development that the broader investment community will note.
