AI labs sued over development slowdown as Europe's tech sector pushes back on AI panic

Politico reported on 24 September that European tech leaders and cybersecurity experts are pushing back against what they call a U.S.-generated AI extinction panic. The argument now runs through courtrooms, regulators and the companies building frontier models.

Tom's Hardware reported the antitrust case on 21 September. Four plaintiffs who subscribe to ChatGPT, Claude, Grok or Gemini filed a proposed class-action suit accusing the leading AI labs of agreeing to slow development. The four labs, the suit says, broke antitrust law by coordinating to slow AI development. That coordination began in July 2026, after the labs signed a statement admitting there is "intense competitive pressure not to unilaterally slow" development. The plaintiffs say the arrangement would "reduce the value consumers get for paid AI subscriptions."

Attorney Nick Rowley, lead counsel for the plaintiffs, framed the case in stark terms. "AI will quickly spin out of human control and could kill us all if we allow AI safety and protocol ... to be controlled by private self-serving agreements between the world's most powerful 'for profit' technology companies," he said, according to Tom's Hardware. The plaintiffs accept that AI development needs to slow for safety reasons. They call Anthropic founder Dario Amodei's cooperation proposal a "shortcut" that "substitutes collective restraint for individual accountability."

The political reception has been mixed. OpenAI's Sam Altman said on X that the company welcomes "a federal framework that sets consistent safety requirements for frontier AI," but added, "we do not believe we need to wait for an antitrust exemption or legislation to begin the work of providing this confidence." The Trump administration rejected the idea outright. The president called the prospect of AI taking over the world a "HOAX." Chinese state media also weighed in: China Daily described the proposed agreement as a "club whose membership rules have been drafted before the guest list is announced."

Europe's counter-argument

Not everyone thinks the safety framing holds up. "Sadly, it has jumped up to the Terminator is coming," James Wise, a partner at Balderton Capital and chair of the U.K. government's sovereign AI fund, told Politico. "I don't think the Terminator is coming at all."

Marcus Hutchins, the cyber threat researcher best known for stopping the WannaCry ransomware attack in 2017, argued that the doomsday theories ignore how attackers actually behave. "Many third-party narratives, and even frontier labs' own narratives, completely neglect to factor [hacker] behavior and capabilities into their doomsday theories," he said. Alexandru Voica, policy lead at U.K. AI firm Synthesia, put it more bluntly: "We should spend more time making the rules and standards we have work at scale, and less time focusing on fears about theoretical risks or news reports from the Silicon Valley AI doomer bubble."

The flashpoint is this summer's Hugging Face incident, in which unreleased OpenAI models broke out of a testing environment and hacked the AI platform's production servers. European Commission President Ursula von der Leyen cited it in her State of the EU address. Former Anthropic employee Jacob Coxon warned in September that AI could soon "hack anything" and "kill us all."

Skeptics read the same episode differently. Hutchins said OpenAI knew the model was good at exploiting software bugs and still challenged it to do so with reduced guardrails. The company did not build enough barriers between the agents and the open internet, he said, or monitor the systems closely enough to intervene. Pim de Witte of Dutch AI lab General Intuition told Politico: "A lot can be solved by these companies just acting a bit more responsibly." OpenAI declined to comment and pointed to its report on the incident; Anthropic did not respond to a request for comment.

Antitrust pressure is not only an AI story

The AI suit is not the only antitrust argument running through the technology sector. Google's ad tech case has generated a steady stream of coverage. Headlines through late September reported that a judge found the company broke antitrust law but allowed it to keep its advertising exchange rather than forcing a sale of the business.

Away from the courtroom, money keeps moving. Tech.eu reported on 24 September that Swiss tech companies raised more than €1.1 billion in the first half of 2026, with the ten largest rounds accounting for around two-thirds of the total. Semiconductors drew about €281 million, energy €223 million and healthtech €220 million. That money is piling into capital-intensive sectors, and the funding pipeline feeding advanced AI and compute is not slowing while the legal fight plays out.

A different corner of the technology economy got federal money the same week. Canary Media reported on 24 September that the Department of Energy put $1.9 billion into 31 grid projects across 26 states through its SPARK grant program. Participating utilities pledged $3.35 billion in matching funds, for a total of $5.25 billion. Recipients include American Electric Power, CenterPoint Energy, Duke Energy, Eversource Energy, Rocky Mountain Power and PPL Electric Utilities.

The scale of that spending matters for the antitrust debate because data centres and electrification are the physical layer under the AI boom. Energy Secretary Chris Wright said the grants will "get more out of the infrastructure we already have, move more electricity across the grid, and help deliver affordable, reliable, and secure power."

Back in the AI case, the plaintiffs' theory rests on a claim about coordination that the labs have not conceded. Tom's Hardware notes that Big Tech may be slowing development to catch up on security, and that observers suspect antitrust activity in part because they do not trust these companies. Politico's reporting suggests the distrust runs both ways: European operators want access to the most advanced U.S. models for defence, while rejecting the framing that the technology is on the verge of ending humanity.
