Euclyd raises €200M for a European answer to Nvidia's inference grip

Euclyd, an Eindhoven chip startup founded in 2024, closed a Series A of more than €200 million (about $231 million) co-led by Samsung, Somerset Capital Partners, the EQT-managed Scaleup Europe Fund and Innovation Industries, the company announced on September 15. Rounding out the syndicate are EIFO, imec.xpand, the Brabant Development Agency and Quadri. The board appointment matters as much as the money: Peter Wennink, the former ASML president and chief executive who spent more than a decade tu

Kioxia wants a $10B US listing as the memory trade cools

Tokyo's NAND maker is shopping for US capital at an awkward moment — the stock is down more than half from its peak, and the market's memory trade has turned. Kioxia is weighing a US share sale of $10 billion or more, targeting an American Depositary Receipt listing as early as spring 2027. Bloomberg reported the plan on September 14, citing people familiar with the matter. The company has not commented, so treat the size and the date as reported, not confirmed. The stated rationale is liquidi

Palantir and Nvidia move to restrict Claude over data fears

The AI slowdown fight is drowning out a quieter story: some of the labs' biggest enterprise customers are starting to walk back. And a former president just told Democrats to make AI safety their opening wedge. Palantir, Nvidia and Booz Allen Hamilton are prepared to restrict or drop frontier AI models unless Anthropic and OpenAI guarantee they will not misuse company intellectual property, according to a report that spread across Reuters and The Information. The trigger is Anthropic's June cha

Microsoft puts xAI's Grok inside Word, Excel and PowerPoint

A rival model is now living inside Microsoft's own productivity suite, consumer GPUs are being vacuumed up by AI builders, and a former Apple researcher raised $50 million to make AI avatars stop staring at you blankly. Microsoft has added Grok as a model option in Copilot for Word, Excel and PowerPoint. The announcement went up on the Copilot blog on September 12 and widened this week: Grok — sold to enterprise admins under the name SpaceXAI, the corporate identity xAI took after SpaceX absorb

Broadcom's CEO says the slowdown call changed nothing about AI demand

The market spent Monday repricing the AI buildout after Dario Amodei's call to pace the frontier. The people who actually write the compute cheques spent the same day saying the number has not moved. Broadcom CEO Hock Tan said the slowdown debate has not touched his AI revenue forecasts. Asked by Jim Cramer on "Mad Money" whether anything in the argument over pacing frontier models had made him reconsider the company's fiscal 2027 and 2028 AI semiconductor targets, Tan answered "No, not in the

OpenAI buys Glass Imaging, the AI behind Honor's zoom

Two hardware stories on the same day from opposite directions: OpenAI quietly bought the camera brain it doesn't have, while Apple put a price tag on the camera brain it does. OpenAI has reportedly bought Glass Imaging, the startup whose neural image processing software already ships in Honor smartphones, for more than $300 million. The Wall Street Journal first reported the deal, and neither company has confirmed it. Glass Imaging sells a product called GlassAI — a neural image signal processo

Cornelis raised $205 million. Its pitch: the network, not the chip

Monday's news ran from the inside of the AI rack to the inside of the White House — a networking challenger that says the GPUs are not the bottleneck, a private Altman-Trump meeting that surfaced the same day the two split publicly on slowing down, and a mathematician's attempt to say what the profession should be for. Cornelis Networks announced roughly $205 million in funding alongside Active Compute Fabric, an open networking architecture that puts programmable compute inside the fabric itse

Claude gets a wealth-management mode, wired into BlackRock and Schwab

While Washington argued about whether to slow frontier AI down, the labs spent Monday doing the opposite of slowing commercially: packaging agents for industries that had been told their compliance rules made them off-limits. Anthropic released Claude for Financial Advisors, a suite of connectors and workflow skills built around the parts of an advisor's day that aren't client-facing. The plugin bundles skills and connectors into one install and works with BlackRock, Charles Schwab, Addepar, En

Tandem Health raises $100M for Europe's AI clinic operating system

Monday afternoon's money went into the least glamorous part of the AI stack — the part with a regulator attached. Stockholm's Tandem Health landed Europe's biggest clinical-AI round to date, Waymo opened its doors in Las Vegas, and Akuity made the case that agents need an identity before they get a production deploy. Tandem Health raised a $100M Series B led by the Scaleup Europe Fund, the €5 billion vehicle the European Commission put EQT in charge of this year. It is the fund's first healthca

Superhuman buys Fathom instead of building its own meeting notetaker

Two deals on Monday, one small and one very loud: a productivity suite bought its way into the meeting record, and Elon Musk's AI company dropped the hardest of its claims against Apple. Superhuman acquired Fathom, the Y Combinator-backed AI meeting notetaker, rather than finish building one itself. CEO Shishir Mehrotra said the company had tested an internal notetaker with select users earlier this year and concluded that doing all parts of meeting recording well is far harder than the finishe

Agents that run for weeks made Temporal a $12.55 billion company

Two funding rounds on opposite ends of the AI stack today: one selling the plumbing that keeps agents alive, one selling music toys that refuse to prompt a model at all. Temporal raised $550 million in a Series E at a $12.55 billion valuation, and the reason it gives is duration. A year ago the company says most of its customer conversations were about payments, onboarding and fulfillment; now customers want agents that run for days, weeks or months without losing state. That is the same proble

Anthropic tells investors it will be profitable for a second quarter

The week AI's biggest labs spent asking for permission to slow down ended with one of them telling shareholders the money is very good — and the number attached to that claim reframes the entire pacing debate. Anthropic has told shareholders its adjusted operating income will be positive for a second straight quarter, with gross margins above 80%, according to the Financial Times, which sourced the report to multiple people with knowledge of the matter. The margin figure comes with the caveat t
