Anthropic Weekly — May 19–26, 2026

Anthropic signed workforce-scale deployment deals with KPMG and Hitachi in the same week it fought the Pentagon in federal court — and a set of leaked financials suggested the company turned its first operating profit in Q2. This is the launch edition of the channel, covering the week of May 19–26 with a brief arc summary from February onward.

Enterprise deployments: KPMG and Hitachi

On May 19, Anthropic closed two of its largest enterprise deals to date within the same news cycle.

KPMG (138 countries, audit / tax / consulting) announced a global strategic alliance integrating Claude into its Digital Gateway platform, built on Microsoft Azure. All 276,000+ KPMG employees gain Claude access. 2 Anthropic designated KPMG as its preferred private equity partner — meaning PE portfolio companies will be routed through KPMG for Claude deployment. A new product called KPMG Blaze (embedded with Claude Code) targets legacy IT modernization at PE-backed companies. KPMG's tax VP Rema Serafi described a workflow that previously "would take weeks" now completing in minutes via Cowork and Managed Agents integrated into Digital Gateway.

Hitachi (operations in 190+ countries) announced a partnership the same day, covering approximately 290,000 employees across all business processes — software engineering, corporate functions, and hardware operations automation. 3 Hitachi is separately committing to train roughly 100,000 AI professionals and launching a Frontier AI Deployment Center across North America, Europe, and Asia (starting with 100 specialists, targeting 300). The focus is physical AI for critical infrastructure — energy grids, transportation networks, manufacturing. Anthropic's chief commercial officer Paul Smith noted that "bringing AI into the systems that run energy grids, transportation networks, and factories demands the highest level of safety and reliability."

Combined, these two deals put more than 566,000 enterprise seats on Claude in a single week. For context, KPMG and Hitachi join PwC (announced May 14, 30,000 U.S. certified professionals) and earlier deals with Goldman Sachs, Visa, and Citi in finance. The professional-services and industrial verticals are now major revenue vectors alongside tech.

Funding: Series H terms agreed at $900B

The Financial Times reported on May 14–15 that Anthropic has agreed terms on a $30 billion Series H round at a $900 billion pre-money valuation, led by Dragoneer, Greenoaks, Sequoia Capital, and Altimeter Capital (each committing at least $2 billion). 4 The round had not officially closed as of May 27. If completed, the valuation would surpass OpenAI's most recent $852 billion figure, making Anthropic the most valuable private AI company.

That's a 2.4× step-up from the Series G ($30B at $380B post-money) closed February 12, led by GIC and Coatue. 5 At Series G time, Anthropic reported a $14 billion annualized revenue run rate — representing more than 10× year-over-year growth — with over 500 enterprise customers each spending $1M+ annually.

The valuation jump gains credibility from leaked Q2 financials, which Markman Capital Insight reported show $10.9B in revenue for Q2 2026 (up 127% quarter-on-quarter) and an estimated $559M in operating profit — Anthropic's first profitable quarter. 6 Compute costs as a share of revenue reportedly dropped from 71% in Q1 to 56% in Q2. These figures are unverified by Anthropic. The company separately secured a 300+ MW cluster of 220,000+ NVIDIA GPUs from SpaceX's Colossus 1 data center in a deal announced May 6, with one analyst report estimating monthly compute costs in the range of $1.25B — a figure Anthropic has not confirmed. 7

The IPO target remains October 2026 (Q4). Wilson Sonsini is serving as legal counsel; Goldman Sachs, JPMorgan, and Morgan Stanley are in early underwriting discussions. No S-1 has been filed with the SEC.

Products and platform: acquisition, MCP tunnels, and Korea

Stainless acquisition (May 18): Anthropic acquired Stainless, the SDK and MCP-server tooling company that has generated all of Anthropic's official SDKs (TypeScript, Python, Go, Java, and others) since the early API days. 8 Stainless also builds SDKs and MCP servers for hundreds of other companies. Stainless founder and CEO Alex Rattray will join Anthropic. The rationale, per Anthropic's head of platform engineering Katelyn Lesse: "Agents are only as useful as what they can connect to."

API updates (May 19): Anthropic released MCP tunnels (research preview) and self-hosted sandboxes for Claude Managed Agents, alongside the ability to update MCP server configurations mid-session. 9

Korea office (May 26): Anthropic appointed KiYoung Choi — former Snowflake Korea general manager, with prior stints at Google Cloud, Adobe, Autodesk, and Microsoft — as Representative Director of Korea ahead of a Seoul office opening. 10 Korea is one of Claude.ai's most active markets globally: Korean users engage with Claude at 3.5× the rate their population share would predict, with usage skewing toward technical and creative work. SK Telecom and law-tech firm Law&Company are among the disclosed Korean customers.

Reminder — Agent SDK credit pricing: Effective June 15, programmatic Claude usage (Agent SDK, claude -p, GitHub Actions, third-party Agent SDK apps) separates from subscription usage limits into a dedicated credit pool: Pro $20/month, Max 5× $100/month, Max 20× $200/month. 11 Interactive Claude Code in terminal or IDE is not affected.

Legal: Pentagon standoff and copyright settlement

DoD supply chain dispute

The federal court conflict with the Department of Defense came to a hearing on May 19. The background: in February, the Pentagon demanded Anthropic remove usage restrictions on Claude for domestic mass surveillance and fully autonomous weapons by a February 28 deadline. Anthropic refused; President Trump directed all federal agencies to stop using Anthropic products on February 27, and Defense Secretary Pete Hegseth designated Anthropic a "supply chain risk" the same day. Anthropic sued in the Northern District of California on March 9, and a federal court granted a preliminary injunction on March 27, covering 17 agencies (including DoD, State, HHS, Treasury, Commerce, DHS, SEC, and the Federal Reserve) — finding Anthropic likely to prevail on First Amendment, Fifth Amendment, and APA grounds. 12

May 19 brought opening arguments in the main case. Separately, on May 1 the DoD signed new AI contracts with xAI, OpenAI, and Google (each capped at $200M) — explicitly excluding Anthropic. 13 The White House was reported to be drafting guidance that would allow federal agencies to bypass the supply chain designation and use Anthropic products. 14 No ruling has been issued.

The $1.5 billion Bartz v. Anthropic settlement — the largest copyright class action settlement in U.S. history — hit a procedural delay at its May 14 final approval hearing. Judge Araceli Martinez-Olguin did not approve the deal, requesting more information on attorney fees (reduced from 20% to 12.5% of the settlement fund) and $50,000 incentive awards for the three named plaintiffs. 15 Plaintiffs' counsel reported that 92%+ of class members had filed claims covering roughly 448,000 of the approximately 482,000 eligible works, at an estimated payout of roughly $3,100 per work.

Also on May 14, 28 authors who opted out of the Bartz settlement filed a new copyright suit — Cruz et al. v. Anthropic — including novelists Dave Eggers (A Heartbreaking Work of Staggering Genius), Angie Cruz (Dominicana), and Vendela Vida, represented by Freedman Normand Friedland. 16 The plaintiffs demand a jury trial and argue the class settlement mechanism allows AI companies to extinguish high-value individual claims at a discount.

A Vox investigation published May 6 documented significant dysfunction in the settlement claims website: author Maureen Johnson submitted claims for 14 books twice (each session taking 90 minutes) and both times was told her records could not be found; a customer service agent responded to her complaint by giggling and saying "Coding is hard." 17 Author Christopher Moore had his complete claims data deleted. The underlying issue, per Authors Alliance executive director Dave Hansen, is poor metadata quality from the pirated library (LibGen/PiLiMi) used as the source dataset.

What to watch

Series H official close: Anthropic has not yet published a closing announcement. The round is expected by end of May or early June.
Bartz final approval: Judge Martinez-Olguin's ruling on the $1.5B settlement is pending. A denial would require renegotiation; approval triggers Anthropic's 30-day deadline to destroy pirated source files.
DoD court ruling: Opening arguments were heard May 19. A ruling for Anthropic could restore federal agency access; a loss would cement the exclusion from classified government contracts.
S-1 filing: No IPO registration statement has been filed with the SEC. Watch for it in Q3 2026 if the October IPO target holds.
Agent SDK credits (June 15): Developers using Agent SDK or claude -p in production need to opt in to claim their monthly credit allocation before the billing change takes effect.
