Nvidia-Groq Antitrust Probe, ADI's $1.55B Deal, and SpaceX's Wild

Several distinct stories are moving AI stocks today: a DOJ antitrust probe into Nvidia’s Groq deal, a fresh semiconductor acquisition, mixed signals from SpaceX, and Apple’s first foldable iPhone raising valuation questions.

Key points

• The U.S. Justice Department is investigating Nvidia’s agreement with AI chip startup Groq over concerns the deal may have been structured to bypass standard antitrust review.
• Analog Devices (ADI) announced it will acquire Alif Semiconductor for an initial sum with a total deal value of up to $1.55 billion.
• SpaceX shares moved in opposite directions across Wednesday and Thursday, with a nearly 4% drop Wednesday followed by a recovery Thursday on data center and UK defense headlines.
• Piper Sandler initiated coverage on Broadcom (AVGO) with an Overweight rating.
• OpenAI and Samsung deepened their partnership on custom AI chip development and ChatGPT enterprise deployment.
• Google confirmed a $15 billion investment in Finland as AI infrastructure increasingly becomes a contest over energy access and geography.

Does the Groq probe put Nvidia in fresh regulatory crosshairs?

Nvidia crossed $5 trillion in market capitalization, as Reuters noted this week, and that kind of scale tends to attract regulatory attention. The DOJ probe into its Groq arrangement adds a concrete risk to the picture. According to a New York Times report cited by EconoTimes, investigators are focused on whether the deal’s structure was designed to sidestep conventional antitrust scrutiny rather than any specific anticompetitive outcome. The distinction matters for investors. A probe is not a lawsuit, and DOJ tech investigations have historically ranged from brief inquiries to multi-year proceedings. Still, any cloud over Nvidia’s ability to consolidate the AI chip supply chain through partnerships is worth watching, particularly as competitors like Groq represent some of the few credible alternatives to Nvidia’s GPU dominance at inference workloads.

ADI buys Alif: why edge AI is drawing acquisition dollars

Analog Devices is paying up to $1.55 billion for Alif Semiconductor, a startup focused on edge AI processing. The deal fits a clear pattern: established chipmakers acquiring smaller firms that have built purpose-built silicon for AI inference at the device level, rather than in the data center. ADI’s core business covers industrial, automotive, and communications analog chips, markets where on-device AI processing is becoming a differentiator. The Alif acquisition gives ADI a faster path into that space than an internal build-out would allow. At $1.55 billion, the price is meaningful for ADI but not balance-sheet-straining. Investors in the broader semiconductor space should read this as further confirmation that edge AI silicon is attracting serious acquisition premiums.

SpaceX: two days, two stories

Wednesday brought a nearly 4% drop in SpaceX shares as investors weighed the cost of the company’s AI infrastructure buildout against its valuation. Thursday told a different story: shares moved higher on reports of a data center overhaul and a developing UK defense deal. The back-and-forth reflects a genuinely unsettled investor debate about SpaceX. The AI expansion is capital-intensive and the company is newly public, meaning there is no long earnings track record to anchor expectations. A defense contract with the UK would provide more predictable revenue, which could help justify the steep valuation that spooked traders just 24 hours earlier.

Other signals worth tracking

Apple’s debut of the foldable iPhone at $1,999, unveiled at its “Surprise and Shine” event, generated consumer attention but also a valuation flag from GF Value, which assessed AAPL as roughly 13% overvalued relative to its intrinsic value estimate. Apple is not a pure AI stock, but its hardware choices increasingly shape how on-device AI gets deployed at consumer scale.

Google’s $15 billion Finland commitment is another data point in the compute infrastructure arms race. As TechBooky reported, the investment underscores that AI data center competition is as much about securing reliable, affordable energy and favorable climates for cooling as it is about raw chip procurement. Finland offers both. Investors tracking cloud capex should note that these commitments are now being denominated in the tens of billions per geography.

The OpenAI-Samsung partnership expansion, covering both custom chip development and enterprise ChatGPT deployment, is a quiet but important development for the custom silicon market. It represents direct pressure on Nvidia’s inference dominance and signals that OpenAI is serious about reducing its dependence on third-party chip supply chains ahead of its anticipated IPO.
