Anthropic IPO: Who Wins and Who’s Pressured

The biggest news of the daywas Anthropic’s highly anticipated S-1 filing. Revenue grew roughly 30-fold in five quarters to $11.6 billion in Q2, the company posted its first GAAP operating profit, and customers paying $100,000-plus nearly doubled in Q3 alone to more than 11,900.

This report doesn’t lift every AI boat equally. It points real, contracted dollars at specific layers. It’s most bullish for the hardware and physical build-out behind the models, mixed for compute middlemen, and a headwind for parts of software.

The Google and Broadcom (NASDAQ:AVGO) TPU complex is the single biggest winner. Roughly $400 billion to $425 billion of Anthropic’s commitments tie back to Google’s TPUs: about $161.2 billion of Broadcom TPU leases, at least $114.5 billion with Google Cloud (some of which may not be TPUs), and an estimated $125 billion to $150 billion of additional TPUs later this decade. Broadcom is even lending up to $42 billion to help fund the rent on those leases.

Alphabet (NASDAQ:GOOGL) gets paid three ways: cloud revenue, TPU demand, and an equity stake that can run up to 14.99%, plus a $20 billion financing line and a $10 billion IPO purchase option. Yet Alphabet stock was up only about 0.2% on filing day, which makes it arguably the most underappreciated beneficiary in the document.

AMD (NASDAQ:AMD) gets a frontier-lab endorsement. Anthropic committed more than $20 billion to AMD’s Helios systems built on MI450 GPUs starting in 2027, with an option for roughly that much again. AMD, in turn, agreed to buy up to $5 billion of Anthropic stock as its GPUs are deployed. That’s about as tight a strategic alignment as a chipmaker can get.

Memory is a quiet but universal winner. The filing names SK Hynix, Samsung, and Micron as its high-bandwidth memory suppliers and flags memory as a supply bottleneck. Every accelerator in that trillion-dollar stack needs HBM, no matter whose chip it is, which makes memory a cleaner way to play the build-out than picking a single chip winner.

Nvidia (NASDAQ:NVDA) wins on volume, with a footnote. About $206 billion of Nvidia-based capacity flows through SpaceX, Nscale, and Lambda, and some of the Microsoft and Amazon spend likely runs on Nvidia, too. But Anthropic’s largest single chip bet is on TPUs, and its multi-chip strategy is exactly the kind of buyer behavior that pressures Nvidia’s pricing power over time. Everything, of course, still runs through TSMC, which the filing names as the critical fab.

The physical build-out is the next layer of upside. “Anthropic Direct” means 20-year data center leases, on-site power, and dedicated facilities, which points toward power generation, cooling and electrical gear, networking, and optics. Think GE Vernova-style on-site power, Vertiv, Arista, Corning, and connectivity names like Astera Labs. Those companies aren’t named in the filing, so this is inference, but it’s the direct implication of a buyer moving down the stack.

SpaceX (NASDAQ:SPCX) picks up a giant customer. At about $3.1 billion a month once capacity is fully delivered, Anthropic would be worth roughly $37 billion a year to SpaceX’s AI compute business. The caveat is that each agreement can be canceled on 90 days’ notice once the initial terms end in early 2027, so this isn’t locked-in revenue.

Then there’s the mixed middle. The hyperscalers collect big committed spend, $110 billion for Amazon (NASDAQ:AMZN) and $44.9 billion for Microsoft, and they sit on huge gains: Amazon’s older notes convert into about 1.84 billion shares at roughly $2 to $5 apiece. But Anthropic competes with their own models, routes 48% of its revenue through their marketplaces for a fee, and is increasingly going direct for compute.

The neoclouds are mixed, too.Nscale and Lambda landing about $86 billion of contracts validates demand for rented GPU capacity. But those deals are contingent on the providers securing financing, which is precisely the pressure point Elon Musk flagged over the weekend (more on that below). Neither CoreWeave nor Nebius is named in the filing, and the biggest buyer is moving toward owning its stack.

The pressured side of the ledger is software. Anthropic is pushing directly into applications with Cowork and vertical solutions for finance, legal, healthcare, and life sciences, which aims squarely at seat-based SaaS workflows. That’s our SaaS Bifurcation framework at work: the winners in the case studies are platforms that embed Claude, like Salesforce, SAP, Shopify, and Snowflake. Cybersecurity is double-edged: models that can find hundreds of vulnerabilities are a powerful tool for defenders and a threat to legacy scanning businesses.

Filing-day trading lined up with this map. Chip and infrastructure names led, with Micron up 3.2%, Arista 3.0%, Nvidia 2.9%, Vertiv 2.8%, Broadcom 2.6%, and TSMC (NYSE:TSM) and AMD each up about 1.9%, while the hyperscalers lagged. The software sector ETF (IGV) was about flat on the day.
