Hyundai to Take Full Ownership of Boston Dynamics in $325 Million SoftBank Buyout

Key Takeaways

Hide

• Hyundai Motor Group is acquiring SoftBank's remaining 9.65% stake in Boston Dynamics for $325 million, making the robotics pioneer a wholly owned subsidiary.
• The buyout triggers a 2021 put option set at a predetermined strike price, heavily discounting the transaction compared to Boston Dynamics’ current estimated $19.6 billion valuation.
• Industry sources report the move is designed to accelerate an initial public offering (IPO) on the Nasdaq by 2027 or 2028.
• Concurrently, Hyundai plans to divest its stake in the RAI Institute back to SoftBank for $100 million to consolidate internal R&D.

The corporate structure behind the world’s most recognizable humanoid robot is consolidating. Hyundai Motor Group is moving to acquire the remaining 9.65% stake in Boston Dynamics held by Japan's SoftBank Group for $325 million, according to reports from South Korea’s Maeil Business Newspaper and KED Global.

The transaction, which key Hyundai affiliates began reviewing in board meetings on June 22, will convert the Waltham-based robotics firm into a wholly owned subsidiary of the South Korean automotive giant. The shift comes at a critical operational juncture as Boston Dynamics pivots from lab-controlled research to aggressive commercial manufacturing targets.

A Steep Discount via 2021 Put Option

The $325 million acquisition price does not reflect Boston Dynamics' current valuation in the booming physical AI sector. Instead, the transaction represents the execution of a pre-negotiated put option established when Hyundai initially acquired a majority stake from SoftBank in June 2021.

Under the terms of that 2021 agreement, SoftBank retained the right to sell its remaining shares back to Hyundai if Boston Dynamics did not go public within a specific timeframe. SoftBank’s 30-day window to exercise the option opened on June 21.

The Valuation Gap: In its annual business report, logistics unit Hyundai Glovis recently estimated Boston Dynamics' enterprise value at 30 trillion won (approximately $19.6 billion)—a 20-fold increase over its 2021 acquisition baseline. At current market estimates, SoftBank's 9.65% stake would be valued at nearly $1.96 billion, meaning Hyundai is securing full control at a fraction of today's speculative value.

Currently, Hyundai's internal ownership is distributed across several key affiliates and leadership:

• Hyundai Motor Co.: 28%
• Executive Chair Chung Euisun: 22.6%
• Kia Corp.: 17.2%
• Hyundai Mobis Co.: 11.3%
• Hyundai Glovis Co.: 11.25%

Accelerating the Timeline for a Nasdaq IPO

According to investment banking sources in Seoul, the primary catalyst for the buyout is a desire to streamline and accelerate Boston Dynamics’ Initial Public Offering (IPO). The developer of the recently unveiled all-electric Atlas humanoid is now anticipated to go public on the Nasdaq by 2027 or 2028.

A successful public listing is strategically vital for Hyundai's overarching corporate governance. Analysts speculate that a high-valuation IPO will provide Executive Chair Chung Euisun with the liquidity required to fund mounting inheritance taxes and finally execute a long-delayed restructuring of the Hyundai conglomerate.

This financial maneuver aligns directly with pressure from the board to transition Boston Dynamics into a high-volume manufacturing powerhouse. Hyundai has already established an aggressive Kia deployment roadmap, mandating that the company scale its production capabilities to support tens of thousands of humanoid units at facilities like the Georgia Metaplant by 2028.

Consolidating R&D: Exiting the RAI Institute

In a separate but related strategic move, Hyundai plans to sell its stake in the Robotics and AI Institute (RAI Institute) back to SoftBank for approximately $100 million. Co-founded in 2022 with an initial $424 million investment, the Cambridge-based RAI Institute was designed as a "blue-sky" research center to look at foundational AI and robotics concepts.

Hyundai intends to utilize the divestment to consolidate its research and development pipelines, pulling core development inside Boston Dynamics' internal labs and existing automotive units.

However, the decision has drawn mild skepticism from market observers. Some analysts note that completely exiting an independent research lab like the RAI Institute could narrow Hyundai's foundational pipeline, potentially undermining its competitive edge in "whole-body" physical AI software at a time when American and Chinese rivals are aggressively scaling up data collection.

For now, the focus remains entirely on commercialization. With its corporate structure cleared of minority constraints, Hyundai’s singular goal is transforming Atlas from a laboratory miracle into an assembly line reality.
