More US investors sue South Korean government over handling of Coupang data breach

Coupang’s massive data breach in South Korea has now become a geopolitical flashpoint as a growing number of the company’s U.S. investors take legal action against the South Korean government.

What began as a regulatory investigation into data security failures has expanded into a broader dispute over alleged unfair treatment of the U.S.-headquartered company.

While Coupang — which operates in South Korea, Taiwan, and Japan — is often referred to as the “Amazon of South Korea,” its worldwide headquarters are actually in Seattle, Washington.

The company’s investors are now seeking international arbitration under the U.S.-Korea Free Trade Agreement (FTA). On January 23, 2026, U.S. investment firms Greenoaks and Altimeter filed a notice with South Korea’s Ministry of Justice, saying they suffered losses from what they characterized as the government’s discriminatory investigation into the data breach. They said they plan to pursue investor–state dispute settlement (ISDS) arbitration under the U.S.-Korea FTA.

South Korea’s Ministry of Justice said Thursday that three more investors, including Abrams Capital, Durable Capital Partners, and Foxhaven Asset Management have now joined the case. They are alleging the government acted unlawfully toward the e-commerce company.

To recap the incident: In December, Coupang disclosed that nearly 34 million Korean customers’ personal information had been leaked in a data breach that had been going on for more than five months. The breach involved customer names, email addresses, phone numbers, shipping addresses, and certain order histories, the company said.

While other tech breaches in Korea resulted in less severe penalties, Coupang has faced extraordinary government pressure. The government reportedly threatened massive fines, suspension of operations, and travel bans for executives while Coupang’s investors allege it also sought to block public communication and repeatedly misrepresented the scope of the breach.

Korea’s Personal Information Protection Commission (PIPC) said that more than 30 million Coupang accounts were exposed — but the facts point to just 3,000 affected accounts, according to Coupang’s investors.

In December, South Korea’s government and the PIPC said the Coupang breach was serious enough to justify higher fines. Under current law, penalties are capped at 3% of revenue, more than $800 million for Coupang, according to the U.S. investors, but some lawmakers have proposed raising the limit to 10% and applying it retroactively.

Even if the new law passes, it wouldn’t apply to Coupang, since the breach occurred before the rules changed. But a Democratic Party lawmaker in the country suggested imposing punitive fines, through either new legislation or a special parliamentary act, and PIPC backed the idea, per news reports. South Korean president Lee Jae Myung also publicly called for heavy penalties, suggesting the company had not faced sufficient consequences.

Based on the notice of intent filing released by the investors’ legal adviser, the investors argue that the South Korean government’s actions constitute an “unprecedented assault” on Coupang. In the filing, they argue:  

The Government’s unprecedented assault on a U.S. company to benefit its Korean and Chinese competitors is an egregious violation of the Treaty, principles of international law, and the historic partnership between Korea and the United States … The Government’s shocking conduct has left the U.S. investors with no choice. If the Government does not immediately cease its attacks against Coupang, fully restore the company’s ability to operate its business, and permanently end its longstanding campaign of discrimination against the company, then the U.S. investors will be forced to seek billions of dollars in damages from Korea to protect their investments in Coupang and remedy the Government’s ongoing Treaty violations, including attempted expropriation.

The filing is a preliminary, pre-litigation step. South Korea’s Ministry of Justice is now reviewing the notice of intent, which kicks off a mandatory 90-day consultation period before formal arbitration can begin.

Coupang, Abrams Capital, and Foxhaven Asset Management did not respond to TechCrunch’s request for comment. Durable Capital Partners could not be reached.

According to the investors’ filing, South Korea’s handling of data breaches has been inconsistent, specifically citing other recent data breaches in South Korea, including KakaoPay, SK Telecom, Upbit, and Alibaba’s AliExpress.

KakaoPay reportedly transferred 54 billion customer records to Alipay Singapore, yet faced only a $10 million fine and a CEO warning, while SK Telecom was fined $91 million after a massive SIM card breach. Upbit and AliExpress also saw minimal government action. The investors say these examples underscore the stark contrast with the government’s response to Coupang.

South Korea’s Ministry of Science and ICT said Wednesday that the Coupang data breach was carried out by a former employee who had worked on the company’s authentication systems and was aware of vulnerabilities in both the authentication framework and key management system.

The Ministry alleges that Coupang failed to report the breach to the Korea Internet & Security Agency (KISA) within 24 hours and did not fully implement a November 2025 data preservation order, leading to the deletion of key web and app access logs. The ministry has referred the matter to investigators and ordered Coupang to submit a prevention plan by February 2026, with compliance monitored through July.

Coupang released a statement, saying that the employee, a Chinese national, accessed data from over 33 million accounts but retained only about 3,000 before deleting it, and that no sensitive info such as payment data, passwords, or government IDs was accessed.

Coupang also replaced its CEO, Park Dae-jun, with Harold Rogers, its U.S. parent’s top lawyer, in December.

Adam Farrar, senior associate at CSIS and senior geoeconomics analyst for APAC at Bloomberg, said on Tuesday’s Impossible State podcast that what began as a major data breach involving Coupang has grown into a broader issue between the United States and South Korea.

Farrar said that the case is amplifying broader U.S. claims of unfair treatment toward American technology firms, raising trade and tariff risks for South Korea as the U.S. Congress becomes increasingly engaged.

“The massive data breach [by Coupang] led to a series of investigations in the National Assembly and some very combative back and forth with Coupang and a series of executives over the past several months,” Farrar said in the podcast. “The additional dynamic here is that Coupang, while driving almost all of its earnings from Korea, is now a U.S.-based company that adds to the dynamic on both sides, impacting how they’re perceived and seen.”

The issue extends beyond Coupang, raising broader questions about whether South Korea is unfairly targeting U.S. companies, Farrar continued.

Critics point to digital policies they say favor domestic firms, including network usage fees on content providers like Netflix, Apple’s App Store and Google Play payment rules, and data localization requirements that limit services like Google Maps on national security grounds.

Blue Origin successfully re-uses a New Glenn rocket for the first time ever

Blue Origin has successfully reused one of its New Glenn rockets for the first time ever, marking a major milestone for the heavy-launch system as Jeff Bezos’ space company looks to compete with Elon Musk’s SpaceX.

But the overall mission’s success may be in question. Roughly two hours after the launch, Blue Origin revealed that the communications satellite that New Glenn carried to space for AST SpaceMobile wound up in an “off-nominal orbit,” meaning something may have gone wrong with the rocket’s upper stage. In other words, it appears the company missed the mark.

“We have confirmed payload separation. AST SpaceMobile has confirmed the satellite has powered on,” the company wrote on X. “We are currently assessing and will update when we have more detailed information.”

AST later said Blue Origin’s rocket placed its satellite into an orbit that was “lower than planned,” so the satellite will have to be de-orbited.

According to a timeline provided by Blue Origin prior to the launch, the upper stage of New Glenn should have performed a second burn roughly one hour after the rocket lifted off from Cape Canaveral, Florida. It’s unclear if that second burn ever happened, or if there were other problems with it, before the AST satellite was deployed.

The company accomplished the re-use feat Sunday on just the third-ever launch of New Glenn, and a little more than one year after the first flight of the new rocket system, which has been in development for more than a decade.

Making New Glenn reusable is crucial to its economics. SpaceX’s ability to re-fly Falcon 9 rocket boosters is one of the main reasons why it has come to dominate the global orbital launch market.

While Blue Origin has already sent a commercial payload to space with New Glenn — Sunday was the second-such mission — the company wants to use the rocket for NASA moon missions, and to help both it and Amazon build space-based satellite networks. Blue Origin is currently finishing getting its first robotic moon lander ready for an attempted launch later this year.

The booster that Blue Origin re-flew on Sunday was the same one the company used in the second New Glenn mission in November. During that mission, the New Glenn booster helped put two robotic NASA spacecraft into space for a mission to Mars, before returning to a drone ship in the ocean. On Sunday, Blue Origin recovered the rocket booster a second time on a drone ship roughly 10 minutes after takeoff.

Any trouble deploying AST’s satellite could present a risk to Blue Origin’s near-term plans for New Glenn. Blue Origin has a deal with the communications company to send multiple satellites to orbit over the next few years as it works to build out its own space-based cellular broadband network.

This story has been updated with new information from Blue Origin and AST SpaceMobile.

Cracks are starting to form on fusion energy’s funding boom

It happens in every emerging industry: founders and investors push toward a common goal, until the money starts to roll in and that shared vision begins to diverge.

Cracks are emerging in the fusion power world, which I saw firsthand at The Economist’s Fusion Fest in London last week. It didn’t dampen the overall buoyant mood, lifted by fusion startups’ fundraising haul of $1.6 billion in the last 12 months. But people had differing opinions on two key questions: When should fusion startups go public? And are side businesses a distraction?

Going public was at the top of everyone’s minds. In the last four months, TAE Technologies and General Fusion have announced plans to merge with publicly traded companies. Both stand to receive hundreds of millions of dollars to keep their R&D efforts alive, and investors, some of whom have kept the faith for 20 years, finally see an opportunity to cash out.

Not everyone is in agreement. Most of those who I spoke to were worried these companies were going public far too early and that they hadn’t achieved key milestones that many view as vital in judging the progress of a fusion company.

First, a recap: TAE announced its merger with Trump Media & Technology Group in December. Though the deal isn’t yet completed, the fusion side of the business has already received $200 million of a potential $300 million in cash from the deal, giving it some runway to continue planning its power plant. (The remainder will reportedly land in its bank account once it files the S-4 form with the U.S. Securities and Exchange Commission.)

General Fusion said in January that it would go public via a reverse merger with a special purpose acquisition company. The deal could net the company $335 million and value the combined entity at $1 billion. 

Both companies could use the cash.

Before the merger announcement, General Fusion was struggling to raise funds, and around this time last year it laid off 25% of its staff as CEO Greg Twinney posted a public letter pleading for investment. It received a brief reprieve in August when investors threw it a $22 million lifeline, but that sort of money doesn’t last long in the fusion world, where equipment, experiments, and employees don’t come cheap.

TAE’s position wasn’t quite as dire, but it still required some funds. Pre-merger, the company raised nearly $2 billion, which sounds like a lot, but keep in mind the company is nearly 30 years old. What’s more, its valuation pre-merger was $2 billion, according to PitchBook. Investors were breaking even at best.

Neither company has hit scientific breakeven, a key milestone that shows a reactor design has power plant potential. Many observers doubt they’ll hit that mark before other privately held startups do. One executive told me, if they were in those shoes, they’re not sure how they would fill time on quarterly earnings calls if the companies didn’t hit scientific breakeven soon.

If TAE or General Fusion doesn’t deliver results, several people feared the public markets would sour on the entire fusion industry.

Now, not all may be lost. TAE has already started marketing other products, including power electronics and radiation therapy for cancer. That could give the company some near-term revenue to placate shareholders. General Fusion, though, hasn’t revealed any such plans.

And therein lies another divide: fusion companies remain split on whether they should pursue revenue now or wait until they have a working power plant.

Some companies are embracing the opportunity to make money along the way. Not a bad strategy! Fusion is a long game, so why not improve your odds? Both Commonwealth Fusion Systems and Tokamak Energy have said they’ll be selling magnets. TAE and Shine Technologies are both in nuclear medicine.

Other startups are worried that side hustles could become a distraction. Inertia Enterprises, for example, told me that they’re laser-focused on their power plant. That jibes with what another investor told me months ago: — they were worried that fusion startups could get distracted by profitable, but tangential businesses and fall off the lead. 

There wasn’t consensus on the right time to go public either. I heard a few proposed milestones. Some believe startups should first reach that scientific breakeven milestone, in which a fusion reaction generates more energy than it needs to ignite. No startup has achieved that yet. The other possibilities are facility breakeven — when the reactor makes more energy than the entire site needs to operate — and commercial viability — when a reactor makes enough electrons to sell a meaningful amount to the grid.

We may have an answer to that question sooner than later. Commonwealth Fusion Systems expects it will hit scientific breakeven sometime next year, and some think the company might use that as an opportunity to go public.

TechCrunch Mobility: Uber enters its assetmaxxing era

Welcome back to TechCrunch Mobility, your hub for the future of transportation and now, more than ever, how AI is playing a part. To get this in your inbox, sign up here for free — just click TechCrunch Mobility!

A few weeks ago, I wrote about how Uber seemed to be everywhere, all at once in the emerging autonomous vehicle technology sector. The Financial Times has now put a number on it. The FT calculated that Uber has committed more than $10 billion to buying autonomous vehicles and taking equity stakes in the companies developing the tech, according to public records and discussions with folks behind the scenes. About $2.5 billion of that is in direct investments, with the remaining $7.5 billion to be spent on buying robotaxis over the next few years, the outlet reported.

We’ve reported on Uber’s numerous investments and deals with autonomous vehicle companies across drones, robotaxis, and freight. Some of its investments include WeRide, Lucid and Nuro, Rivian, and Wayve

This rather large number (and particularly that $7.5 billion) got me thinking about another transformative era in Uber’s history and how it has visited these asset-heavy shores before. Uber might have started with a plan to be asset light, but for a brief period it did quite the opposite.

Uber went on a moonshot spree between 2015 and 2018. It launched electric air taxi developer Uber Elevate and the in-house autonomous vehicle unit Uber ATG, which would be boosted by its acquisition of Otto in 2016. It also snapped up micromobility startup Jump in 2018. 

And then in 2020, Uber pulled the asset-heavy rip cord, ostensibly leaving all of those moonshots behind. Uber sold Uber ATG to Aurora, Jump to Lime, and Elevate to Joby Aviation. But it didn’t completely divest; it kept equity stakes in all of them.

Uber is now entering into a new and different asset-heavy era. It’s not plunking down millions, or even billions, to develop the technology in-house, although I’m sure folks there would be quick to pipe up that there is always R&D happening over at Uber. Instead, it appears to be focused on owning (or perhaps leasing) the physical assets.

That could mean interesting line items on Uber’s balance sheet in the future. 

Owning fleets of robotaxis built by other companies might not have been the original vision of Uber, or its former CEO Travis Kalanick, who has said the company made a mistake when it abandoned its AV development program. But this new approach could still get it to the same end point.

Earlier this month, I interviewed Eclipse partner Jiten Behl about the venture firm’s new $1.3 billion fund and where that money might be headed. The firm, as I wrote, intends to incubate more startups (e.g., it was behind the Rivian spinout Also). Behl wouldn’t give me details, only stating, “We’re definitely working on a couple of really cool ideas.” He also said Eclipse is particularly interested in startups that work across enterprises.

Thanks to one little bird and some document diving by senior reporter Sean O’Kane, it looks like a seed round announcement is imminent for a San Francisco-based startup working on an autonomous hauler that I’ve been told doesn’t have a driver cab. This sounds similar to what Einride has built, but since we haven’t seen it, we’ll have to wait. 

The company’s roster isn’t big, but it is chock-full of Silicon Valley tech elite, including a founder who was at Uber ATG, Pronto, and Waabi. Stay tuned for more.

Slate is back with more capital as it prepares to put its first affordable pickup trucks into production by the end of 2026.

The electric vehicle startup, which got its start with backing from Jeff Bezos, raised another $650 million in a Series C funding round led by TWG Global. Keep your eye on TWG. This is the firm run by Guggenheim Partners chief executive (and Los Angeles Dodgers owner) Mark Walter and investor Thomas Tull. 

Slate has raised about $1.4 billion to date, and its previous investors include General Catalyst, Jeff Bezos’ family office, VC firm Slauson & Co., and former Amazon executive Diego Piacentini, as TechCrunch first reported last year.

Other deals that got my attention …

Glydways, a San Francisco-based startup developing personal autonomous pods designed to operate on dedicated 2-meter-wide lanes in cities, raised $170 million in a Series C funding round co-led by Suzuki Motor Corporation, ACS Group, and Khosla Ventures. Existing investors Mitsui Chemicals and Gates Frontier and new investor Obayashi Corporation also participated. But wait, there’s more

GM and Ford are reportedly talking to the Pentagon about whether the auto industry can help the military revamp its procurement program and find cheaper, faster ways to buy vehicles, munitions, or other hardware, the New York Times reported, citing anonymous sources.

Loop, a San Francisco-based startup, raised $95 million in a Series C funding round led by Valor Equity Partners and the Valor Atreides AI Fund, and includes investments from 8VC, Founders Fund, Index Ventures, and J.P. Morgan’s late-stage fund, Growth Equity Partners.

Monarch Tractor, the startup developing electric, autonomous tractors, has moved on to (ahem) a different pasture. The startup’s assets have been acquired by Caterpillar after struggling to pivot to a software services business.

Uber is increasing its stake in Delivery Hero by 4.5%, the Financial Times reported. Uber agreed to buy about 270 million euros in shares from Prosus, the Dutch investment group and Delivery Hero’s largest shareholder.

Notable reads and other tidbits

Doug Field, the high-profile executive who shaped Ford’s electric vehicle and technology strategies over the past five years, is leaving. Notably, Ford is shaking up the organization as well, creating a “product creation and industrialization” team to be led by COO Kumar Galhotra. Any guesses where Field is headed next? Perhaps he’ll return to Silicon Valley. 

Lightship, the all-electric RV startup, is expanding its Colorado-based factory by another 44,000 square feet, which will allow it to quadruple its manufacturing capacity.

Rivian and battery recycling and materials startup Redwood Materials partnered years ago. We’re now seeing the fruits of that relationship. Redwood is installing battery energy storage at Rivian’s factory in Illinois. The catch? Redwood is using 100 second-life Rivian battery packs, which will provide 10 megawatt-hours (MWh) of dispatchable energy to reduce cost and grid load during peak demand periods.

Tesla created a new self-driving app that makes it easier for owners to subscribe to its Full Self-Driving software and see statistics on how — and how often — they use it. This may not be huge news, but it did catch my eye because of the gamified qualities of these new stats. 

Waymo, as per usual, has a few news items this week. The Alphabet-owned company started testing its autonomous vehicles on public roads in London. It also removed its waitlist in Miami and Orlando to scale its robotaxi services in the two cities. 

One more thing …

This newsletter isn’t my only project that is leaning more heavily into robotics. My podcast, the Autonocast, is too, as the worlds of autonomous vehicles, AI, and robotics mash together. Check out this interview with Foxglove founder Adrian MacNeil, who previously worked at Cruise.
