Nvidia Is Buying Its Way Into Every Layer of the AI Stack — While the Stock Takes a Breather

Nvidia confirmed a $12.9B Hugging Face acquisition, invested $3.5B in MediaTek, and faces a DOJ inquiry as its stock slips below key averages.

Nvidia spent the first half of September behaving less like a chipmaker and more like a holding company for the entire artificial intelligence economy. In a span of roughly two weeks, the company confirmed a multi-billion-dollar acquisition, deepened a partnership with a Taiwanese manufacturing ally, backed a sovereign-AI push with Palantir, unveiled a gigawatt-scale buildout in Australia, and surfaced as a possible anchor investor in what could become the largest IPO on record. Reuters Breakingviews framed the flurry as a kind of insurance policy — a deliberate layering of acquisitions and ecosystem control designed to shield Nvidia from the unpredictability of the AI cycle it helped create.

The centerpiece came on September 3, when Nvidia confirmed it would acquire Hugging Face for approximately $12.9 billion. Of that total, $11.9 billion goes to the platform's investors, with up to $1 billion more set aside as stock-based retention awards for employees joining Nvidia. Reuters read the move as an effort to tighten the company's grip on open-source AI models — a segment that had traditionally served as a counterweight to closed systems.

A Convertible Bond, a DOJ Inquiry, and a Gigawatt Bet

Days earlier, at the start of September, Nvidia had already moved to expand its alliance with MediaTek. The partnership spans cloud AI infrastructure, on-device AI computing, and the automotive sector, with MediaTek committing to adopt Nvidia's NVLink Fusion platform. Alongside that deal, Nvidia invested $3.5 billion in MediaTek convertible bonds, according to media reports — a stake that gives the company direct financial exposure to a key partner in the chip supply chain.

Not every headline was welcome. On September 9, reports emerged that the U.S. Department of Justice is examining whether Nvidia structured an earlier licensing arrangement with AI startup Groq in a way that sidestepped antitrust review. Both the Hugging Face deal and the Groq inquiry now sit a week and a half to two weeks in the past, yet both continue to weigh on how investors value the company.

Meanwhile, the physical buildout continues. Working with Australian cloud partners and infrastructure providers, Nvidia announced an expansion of land, power, and building capacity for so-called DSX AI factories, targeting up to two gigawatts by 2027. The Palantir collaboration, announced September 10, follows a similar logic: the two companies are combining Palantir's sovereign-AI software with Nvidia's Nemotron models, designed as open systems, to bring secure AI into critical supply chains. The first deployment runs inside Nvidia's own operations. The arrangement signals that Nvidia increasingly positions itself as an infrastructure provider for government-adjacent and security-sensitive applications — not merely a supplier of data-center chips.

Then, on Friday, Reuters reported that Anthropic is in talks to bring Nvidia in as an anchor investor for a listing that could become the largest IPO in history. Three announcements, three distinct layers — infrastructure, software sovereignty, capital markets — but a single thread: Nvidia sits at every junction where AI currently generates revenue or is expected to.

Huang Says the Buildout Is Still Young

Speaking at Goldman Sachs' Communacopia + Technology Conference on September 10, CEO Jensen Huang said the AI expansion remains in its early stages, with demand for AI infrastructure holding firm. Reuters took the remarks as confirmation that the data-center investment cycle is still running — a cycle from which Nvidia, as the central supplier, stands to benefit.

The market, however, has been slower to cheer. The stock closed Monday at EUR 182.58, down 3.0% from the prior session. Over the past seven trading days, the decline adds up to 6.0%, leaving the shares below their 50-day moving average of EUR 185.27 — a sign that short-term momentum has faded even as operating news stays largely positive.

A separate snapshot put the shares at EUR 183.50 after a 2.5% drop on the day and a 7.7% slide for the week, placing them 9.4% beneath the 52-week high of EUR 202.50 reached in May. Even so, the stock remains up 21% over twelve months, suggesting the current softness looks more like a digestion phase than a reversal.

Insiders Lighten Up as the Story Broadens

Selling from the leadership ranks drew additional scrutiny. Board member Mark Stevens disposed of roughly 1.85 million shares through trust structures between August 31 and September 4. Director Tench Coxe, meanwhile, transferred 500,000 shares as a gift out of a trust for which he serves as trustee. Transactions of this kind are hardly unusual among executives, but they land at a moment when investors are parsing the company's valuation following the announcement of multibillion-dollar takeovers and investments.

What emerges is a portrait of a company steadily redrawing its own boundaries — from pure chip hardware toward software, sovereign AI infrastructure, and strategic equity stakes in partners. The open question is no longer whether Nvidia keeps growing; the Palantir tie-up, the Australian buildout, and the possible Anthropic talks all point in one direction. It is whether a business that simultaneously acts as chip supplier, cloud builder, software investor, and potential IPO anchor can still be valued as a single, clearly defined enterprise — or whether it is turning into a conglomerate whose risks will increasingly sit somewhere other than the chip business. Nvidia's upcoming quarterly earnings call, announced for the coming weeks, will have to answer more than any individual partnership announcement of the past fortnight.
