Four Owners in Thirty Years: The Strange Corporate Journey of Boston Dynamics

If you've ever watched a video of a four-legged robot trotting across a parking lot, climbing stairs, or getting kicked by an engineer to test its balance, you've seen Boston Dynamics' work. The company behind Spot, Atlas, and the dancing-robot videos that regularly go viral has spent three decades building some of the most advanced walking machines on Earth. What's less well known is that it has also spent those three decades being bought, sold, and bought again — by a search giant, a Japanese conglomerate, and now, almost entirely, by a South Korean car maker.

Born in an MIT Basement

Boston Dynamics traces its roots to 1992, when it was spun out of the Leg Laboratory, a research group run by robotics engineer Marc Raibert at MIT and, earlier, Carnegie Mellon. Raibert's obsession was dynamic balance — getting machines to stay upright the way animals do, through constant, active correction, rather than the wide, stable stances most robots of the era relied on.

That research focus produced some of the strangest and most memorable machines in robotics history. BigDog, unveiled in the mid-2000s with funding from the US military's DARPA, was a headless, four-legged robot that could carry heavy loads over rough terrain and famously recovered its footing after being shoved or kicked on ice. PETMAN, a humanoid built to test chemical-protective suits, followed. These were research prototypes, not products, but they established the company's signature: robots that moved like living things, not machines on wheels.

Google Comes Knocking

Boston Dynamics stayed a relatively obscure, defense-funded engineering shop for two decades, until Google quietly bought it in December 2013. The acquisition was part of a short-lived robotics buying spree led by Andy Rubin, the Android co-founder who had been tasked with building a robotics division inside the company. Google (soon to be restructured as Alphabet) picked up roughly a dozen robotics firms in that period, with Boston Dynamics as the highest-profile name in the portfolio.

The Google era didn't last. Rubin left the company in 2014, and without his backing, the robotics moonshot lost momentum internally. Boston Dynamics kept building robots — Spot's early prototype dates to this period — but Alphabet never found a clear commercial path for it, and in June 2017 it announced it was selling the company to Japan's SoftBank, the investment conglomerate behind the massive Vision Fund. Terms weren't disclosed.

The Hyundai Era Begins

SoftBank's ownership proved to be another way station. In December 2020, Hyundai Motor Group announced a deal to acquire roughly 80% of Boston Dynamics from SoftBank, in a transaction various reports valued at somewhere between roughly $880 million and $1.1 billion. The deal closed in June 2021, giving the South Korean automaker — better known for Sonatas and Elantras than robots — a controlling stake in the world's best-known robotics company.

The logic made more sense than it first appeared. Hyundai was already pouring money into future mobility and automation, and a robotics arm gave it a path into factory automation, logistics, and eventually humanoid labor, well beyond the car business. SoftBank retained a minority stake, reportedly under 10%.

Under Hyundai, Boston Dynamics finally started treating its robots like products rather than demos. Spot, the dog-like quadruped, moved from research curiosity to commercial tool, deployed for remote inspection in power plants, construction sites, and industrial facilities; the company has reported well over a thousand commercial Spot deployments, including a number with police departments for bomb-disposal and hazard scouting work.

Atlas Gets a Reboot

Atlas, the humanoid that spent over a decade as Boston Dynamics' flagship research platform — jumping, backflipping, and occasionally faceplanting in viral videos — was built on hydraulics, which made it powerful but heavy, noisy, and expensive to maintain. In April 2024, Boston Dynamics retired that version entirely and introduced a new, fully electric Atlas designed from the ground up for real commercial work rather than lab demonstrations.

The company has been deliberately cautious about the rollout, describing a gradual process similar to its approach with Stretch, its warehouse box-moving robot: a small group of customers testing the new Atlas over several years before any wider release. The first customer is Hyundai itself, which plans to trial the robot inside its own automotive manufacturing operations — effectively letting its own factories serve as the proving ground for a robot it now owns.

Closing the Loop

The corporate story took another turn in mid-2026. SoftBank, which had held onto a residual stake of roughly 9.65% since the 2021 deal, exercised a put option tied to the original agreement — triggered, according to reporting at the time, by the fact that Boston Dynamics had not gone public in the US within the deal's original window. Hyundai affiliates agreed to absorb that remaining stake, with reported deal values in the range of $300–335 million, moving Boston Dynamics toward becoming a fully owned Hyundai subsidiary for the first time since its MIT days.

Hyundai has framed the move partly as paperwork clean-up ahead of a possible future listing for its robotics business, and partly as a straightforward bet: the company has said it intends to put Atlas to work on real assembly-line tasks at its Georgia manufacturing plant starting around 2028, with more complex component-assembly roles potentially following by 2030.

Why the Ownership History Actually Matters

It's tempting to treat corporate ownership changes as footnotes next to the robots themselves, but Boston Dynamics' trajectory is a useful case study in how differently big companies have approached humanoid and legged robotics. Google saw it as a moonshot bet without a clear product story. SoftBank treated it as a portfolio asset inside a much larger investment vehicle. Hyundai is the first owner actually building the factories the robots are meant to work in — which may be exactly the kind of owner a 30-year-old research company finally needed to become a product business instead of a collection of remarkable, expensive demos.
