Anthropic passed OpenAI. Who else shifted this week.

Ramp's payment data is in. 50,000+ companies, actual card spend — and Anthropic passed OpenAI in business adoption this week. That's the number to hold onto. Everything else follows from it.

This week the signal was concentrated around three threads: market share flipped in verified payment data, n8n landed SAP and Mercedes-Benz in the same seven days, and Anthropic shipped products that directly compete with the legal and SMB software companies that built on its API. Three separate moves, same direction. The infrastructure layer is consolidating faster than most operators are tracking.

Models + launches

Anthropic passed OpenAI in business adoption. Ramp's dataset — 50,000+ companies, real payment data, not surveys — shows Anthropic at 34.4% business adoption versus OpenAI's 32.3%. That's a 26-point gain in 12 months while OpenAI declined 1pp. [1] Any operator still defaulting to OpenAI for new builds should now be making that case actively rather than assuming it.

Vercel's 7-month AI Gateway production report backs this up from a different angle: Anthropic commands 61% of AI spend across 200,000 teams, versus OpenAI's 12% and Google's 21%. Agentic workloads jumped from 32% to 59% of total token volume in six months. [2] High-volume teams run 35 distinct models on average. The "pick one provider and ship it" assumption is two quarters stale.

| Metric | Anthropic | OpenAI | Google | |---|---|---|---| | Business adoption, % of 50K+ co. (Ramp) | 34.4% | 32.3% | — | | Year-over-year change | +26pp | −1pp | — | | AI spend share, 200K teams (Vercel) | 61% | 12% | 21% | | Agentic workload share (Vercel, 6-month change) | was 32% | — | now 59% total |

Claude for Small Business shipped. [3] Fifteen ready-to-run agentic workflows pre-wired to QuickBooks, PayPal, HubSpot, Canva, DocuSign, Google Workspace, and Microsoft 365. No implementation fee. Any operator currently billing to configure bespoke Claude integrations for SMB clients just had their standard onboarding pitch undercut by Anthropic's own product team. This matters more than the product itself — it signals that Anthropic is building end-customer relationships, not just API adoption.

Tooling shifts

n8n is now enterprise infrastructure. SAP made a strategic investment at a $5.2B valuation and embedded n8n inside SAP Joule Studio — which means n8n workflow automation is now native to 99% of the world's largest companies. [4] The same week, Mercedes-Benz's global deployment across 164,000 employees went public, with production multi-agent orchestration running customer inquiries, ticket routing, and log anomaly detection. [5]

The competitive argument for n8n over Zapier and Make in enterprise sales just changed shape. Two named Fortune-tier referenceable deployments in seven days isn't momentum — it's a market statement. If you're still framing n8n as "cheaper Zapier," update the pitch. (The cost math still closes itself — I've run that $40/month-versus-$1,800/month conversation more times than I can count. And n8n vs Zapier vs Make is still the right question to start with before any automation build.)

SMB angles

Anthropic started competing with its own API customers. Claude for Legal launched with MCP connectors for Westlaw, DocuSign, and Box — document review, deposition prep, and case research automation in the same managed stack as finance and SMB workflows. [6] Clio ($500M ARR), Harvey ($190M ARR), and Legora ($100M ARR) all run on Claude's API. All three are now competing against Anthropic's own vertical offering in their primary category.

The vendor-undercuts-platform-customer pattern is live in AI vertical software. If you're building a category product on a single foundation model API, model the "vendor enters my market" scenario before it becomes reactive.

This will not stop at legal. Finance agents, SMB workflows, and healthcare integrations are in the same product cycle. The operational window for building a durable vertical product on a single-vendor foundation model API is narrowing — the moat has to be in distribution and domain data, not in the integration work. (That's the shape of defensible fractional digital operations work — infrastructure plus the institutional knowledge that can't be templated.)

Security alert: supply chain and physical access, same week. Two separate threats to patch now.

TanStack's 42 npm packages (@tanstack/query, table, form, virtual, store, start) were poisoned for six minutes on May 11 with credential-harvesting malware targeting AWS, GCP, Kubernetes, Vault, GitHub, npm, and SSH keys. [7] If any pipeline ran npm install on those packages during that window, treat the host as fully compromised and rotate all credentials immediately. The payload ran — this isn't theoretical.

BitLocker YellowKey is an unpatched PoC (live on GitHub) that bypasses BitLocker on Windows 11 and Server 2022/2025 by placing files on a USB, rebooting into WinRE, and holding CTRL to spawn a shell with full disk access — under 60 seconds, no authentication required. [8] No Microsoft patch yet. Set a BitLocker PIN and a BIOS password today. Don't wait for Patch Tuesday.

Adjacent to watch

Amazon's AI killed the ecommerce browse moment. Amazon replaced Rufus with Alexa for Shopping, which includes a "Buy for Me" feature that shops other retailers' sites on the customer's behalf. [9] The AI is now the default comparison shopper at Amazon's search bar. The discovery moment where customers independently browsed your product, built intent, and chose you — that's the moment being replaced by an agent that makes the call for them.

If you're selling through ecommerce or running a brand that depends on top-of-funnel product discovery, your product now needs to win a recommendation from an AI before it wins a customer's attention. Optimizing for search engines and optimizing for AI shopping agents are not the same problem.

What I'm watching: whether Claude for Small Business cuts into implementation fees enough that SMB operators feel it in Q3 pipeline — or whether the pre-wired templates are too rigid for the real-world variation operators actually encounter. The product is real. The question is whether SMB buying behavior is ready for agent-first software without a human to hold their hand through onboarding.

  • Vercel's 7-month production data: Anthropic commands 61% of AI spend; agentic work jumped from 32% to 59% of token volume in 6 months
  • n8n hit $5.2B with SAP's investment and Mercedes-Benz's global deployment in the same week — the "cheap Zapier alternative" frame is dead
  • Anthropic launched pre-wired SMB workflows and legal agent templates — it's now a direct competitor to customers who build on its API
  • If your pipeline ran npm install @tanstack/* on May 11 between roughly 15:00–15:06 UTC, rotate all credentials now
  • BitLocker YellowKey bypasses disk encryption in under 60 seconds of physical access, no patch yet — set a PIN
  • Amazon's "Buy for Me" replaced the ecommerce browse moment; your product now has to win an AI's recommendation before a customer's attention
