The Comp Set Just Lost Its Referee
With no scheduled public print before 2027, the reference price for frontier AI is set by brokers and lenders — and one of those lenders publishes its opinion in New York in a planned high-yield offering.
Two incompatible explanations, one identical consequence
Altman's stated reason is alignment and safety work; he explicitly denied capital pressure. His own CFO told employees in August that the company "will be a public company in 2027," and a confidential S-1 went in during June. The New York Times separately reported that bankers advised against listing, citing SpaceX-style volatility and unclear finances. Pick either account and the structural result is the same: no date, no banker, no structure, and a gating condition with no accepted standard to clear.
What that removes is not liquidity — employee tenders and ROFR-gated secondaries still function. It removes price discovery. The listing was the only event capable of putting a public number on frontier AI. Without it, private marks stay model-derived and unfalsifiable for another 12-24 months. Two consequences follow, in order of how fast they hit a book. IRR degrades on timing alone: TVPI holds, the clock does not, and any position underwritten to a 2026-2027 frontier comp just lost 18-24 months of return velocity. And repricing, when it comes, arrives through structure rather than tape — down rounds, layered preference, secondary discounts. Slower, quieter, and with no floor under it.
Who sets the reference now
Three parties, none obliged to publish a methodology: secondary buyers, tender agents, and lenders holding private shares as collateral. SoftBank is the cleanest example of the last. It has committed $64.6B for about 13% of OpenAI, financed partly with a $10B margin loan and an $11.87B two-year facility, has repaid a $40B bridge down to $25.9B, and has a final $10B tranche due October 1. Its preferred shares convert to common only at an IPO, so the deferral postpones the conversion event embedded in the financing.
Here is the mechanic most books miss. A margin loan against private shares has no daily price. Lenders fall back on the last primary round, secondary indications, or a negotiated haircut — so a change in OpenAI's reported valuation can hit a balance sheet before a single share trades. SoftBank is marketing a possible $10-20B high-yield deal in New York.
That bond print is the market's stated opinion on how to discount an undated private AI stake. It is public, it is dated, and almost nobody will use it as a discount rate.
Where the reporting diverges
Coverage agrees the print is gone and that secondaries become the clearing mechanism through 2027. It splits on whether the issuance window itself is shut, and there is counter-evidence: Electra Therapeutics pricing up to $347.2M on Nasdaq at $14-16 and Bamboo Insurance up to $700M on NYSE at $18-20, backed by OrbiMed and by CVC and White Mountains respectively. Markets are open. What is closed is access for issuers carrying frontier-AI narrative risk — an asset-specific disclosure problem, not a market-wide freeze.
So stop treating the last private round as a reference and start deriving one. The bond market will price undated private AI collateral in that offering; a distressed strategic buyer priced horizontal software. Both are harder numbers than any up-round sitting in a September mark.
What to do
Pull SoftBank's high-yield offering terms when the deal prices, extract the implied haircut on undated OpenAI collateral, and adopt it as the house discount rate for undated private AI stakes before the September 30 valuation committee.
Re-underwrite every AI position whose return case assumed a 2026-2027 frontier-AI public comp by pushing exit assumptions 18-24 months right, and deliver the revised IRR and DPI schedules to IC this quarter.
Draft a written pricing and diligence framework for frontier-lab secondary opportunities at a defined discount to last round this quarter, so the mandate exists before employee and 2021-2023-vintage supply reaches the desk.
