Anthropic in Talks to Buy Decart for $6 Billion — Its Largest Deal Ever

Anthropic is reportedly in advanced talks to acquire Decart, an Israeli AI infrastructure startup, for approximately $6 billion — a deal that would be the largest acquisition in the company’s history and one of the most consequential M&A moves in the AI industry to date.

The report, first published by Bloomberg on August 13, 2026, sent ripples through the AI ecosystem, not because of the price tag alone, but because of what it signals: frontier labs are now buying infrastructure technology companies outright to attack the single biggest constraint on their business — compute efficiency.

What Decart Actually Does

Decart is not another foundation model startup chasing benchmarks. Founded in Tel Aviv, the company builds software that helps AI chips operate more efficiently — technology that sits at the layer between raw GPU hardware and the models that run on it.

That positioning matters. Decart’s tooling addresses two problems that keep every frontier lab’s infrastructure team awake at night:

1. Training cost reduction. Its GPU optimization engine can meaningfully reduce the cost of training large models — a line item that runs into the billions for companies like Anthropic.
2. Hardware portability. Decart’s software makes it easier to switch between AI chips from different vendors. As the Wall Street Journal reported in May 2026, this capability — reducing lock-in to any single supplier — is precisely what attracted Nvidia as an investor, even though easier chip-switching might seem contrary to Nvidia’s interests. Nvidia’s participation signals that the GPU giant would rather be close to this technology than blindsided by it.

Decart’s trajectory has been steep. The company emerged from stealth with $21 million led by Sequoia Capital, raised another round a month later, then jumped to a $3.1 billion valuation on a $100 million round in August 2025. In May 2026, it closed a $300 million round led by Radical Ventures at close to a $4 billion valuation, with Nvidia joining as an investor and Amazon signing on as a strategic customer.

Now, barely three months later, Anthropic is reportedly willing to pay roughly $6 billion — a premium of about 50% over that last private mark.

Why Anthropic Wants It

According to Bloomberg Law’s reporting, the potential acquisition is intended to help Anthropic’s existing computing infrastructure absorb more demand. Read that carefully: this is not about buying more chips. It is about making the chips Anthropic already controls do more work.

The context makes the motivation obvious. Anthropic has committed to enormous compute commitments over the past year, including a landmark arrangement under which Google agreed to backstop lease payments, effectively supporting what amounts to a $35 billion chip deal for Anthropic, as Bloomberg reported in June 2026. When your compute bill is measured in tens of billions, even single-digit-percentage efficiency gains translate into billions of dollars of savings — and, just as importantly, into more usable capacity without new data centers.

Israeli tech publication Calcalist adds another dimension: a completed deal could make Decart the foundation of an Anthropic development center in Israel, giving the company a foothold in one of the world’s densest concentrations of systems engineering talent.

There is also a defensive angle. Calcalist reports the talks follow advanced discussions between Decart and Nvidia about a deal of their own. If Nvidia had absorbed Decart, its efficiency and portability technology could have been steered toward Nvidia’s own stack — or priced out of rivals’ reach. Acquiring Decart lets Anthropic lock in the capability exclusively, a pattern familiar from every platform war in tech history.

The Bigger Picture: Consolidation Begins

Until now, the defining characteristic of the AI boom has been separation: model labs build models, cloud providers sell compute, and infrastructure startups sell to everyone. Anthropic buying Decart blurs those lines. A frontier lab is reaching down the stack to own a horizontal infrastructure layer.

Three implications stand out:

Vertical integration becomes the norm. OpenAI has already engineered its own custom accelerator strategy with Cerebras, and every major lab now employs large systems teams. Buying a proven optimization layer outright is faster than building one, and $6 billion is small change relative to Anthropic’s compute commitments and its reported new funding round, which could value the company at up to $170 billion.

Infrastructure startups get a bid. For the ecosystem of companies building chip-efficiency, scheduling, and portability software, this deal establishes a price benchmark and — crucially — an exit path. Expect more labs and hyperscalers to go shopping for similar capabilities.

Nvidia’s position gets more interesting. The Decart episode shows Nvidia playing both sides: investing in technology that reduces chip lock-in while simultaneously having been in talks to acquire it. As its customers increasingly hedge across silicon suppliers, Nvidia appears to prefer engagement over denial.

Caveats

The deal is not finalized. Bloomberg notes the talks could still fall apart or see the price change — standard language for any negotiation of this size, and a reminder that Decart was deep in talks with Nvidia until recently. But the direction is clear: Anthropic has identified compute efficiency as a strategic priority worth billions, and it is willing to make the largest acquisition in its history to own it.

If completed, the Decart acquisition will be remembered less as a $6 billion purchase than as the moment AI’s biggest labs stopped renting their infrastructure advantages and started buying them.
