Secondary market signals

Secondary market signals: bid/ask/trade indications from Hiive (hiive.com), Forge Global, Caplight Index, and tender prices reported in the press.

No active listings found

We monitor Hiive, Forge Global, and EquityZen for Stability AI listings. As of July 2026, no verified secondary market activity has been recorded.

Secondary listings for private companies appear without announcement and typically close within days. When a listing appears, it often signals an upcoming tender offer or funding round.

Primary round history as valuation signal

In the absence of secondary market data, the funding history below is the primary valuation anchor. Method C (time-decay) uses this data to estimate current value.

Confidence breakdown

How much we trust each of the four valuation methods for this specific company, and why.

Method A — Peer-multiple

weight 25%→ $0.7B75% confidence

Growth-weighted peer EV/Revenue: 37.2x → 35% private-company discount → 24.2x on $30M revenue

Method B — Secondary-implied

weight 45%suppressed25% confidence

↳ Effectively excluded from the blend — this method is structurally unreliable for this company.

No verified secondary market data available — estimate relies on primary round, peer multiples, and sector momentum.

Method C — Primary time-decay

weight 20%→ $1.3B48% confidence

$1B round (2024-09-01) × 1.40× growth × 0.91× multiple decay over 1.9 years

Method D — Sector momentum

weight 10%→ $1.4B32% confidence

$1B × (1 + 22% p.j.)^1.9yr = $1.4B via BOTZ ETF-proxy

Overall confidence

43%

Weighted average of the four methods. Above 60% is high, 35–60% medium, below 35% low.

Transparent assumptions

What we assumed where exact data isn't available. If any of these don't match your situation, the numbers above will be off.

Fully-diluted share count

160M shares

We don't have authoritative cap-table access for private companies. The number above is reconstructed from SEC Form D filings, secondary-market price-vs-valuation math, and leaked share-class summaries. Actual fully-diluted count (including unvested option pool and SAFEs) may differ by 5–15%.

Common-stock waterfall

1.0× to common

We assume a clean common-stock outcome — i.e. preferred-share liquidation preferences and ratchets do not extract value before common. In a down-exit, this assumption can be very wrong: preferred stack can take 30–70% of proceeds.

Private-company illiquidity discount

35% off public peers

Applied to Method A (peer-multiple). Per-company because category leaders with deep secondary markets and a clear IPO path warrant a smaller discount than early-stage names. The literature range is 10–35%; for Stability AI we use 35% based on secondary-market depth, valuation history, and proximity to liquidity.

Revenue growth assumption (Method C)

20% YoY

Compounded forward from the last primary date to today to estimate the company's value drift. Set per-company based on disclosed or reported ARR trajectory. Method C is further capped at 1.3× the most recent secondary trade (if any) to stop runaway extrapolation when revenue growth outpaces what the market is actually paying.

Sector ETF momentum (Method D)

BOTZ @ 22%/year

Method D applies the trailing return of BOTZ as a market-proxy adjustment to the primary valuation. Crude — meant as a tiebreaker when peer and secondary data conflict, not as a primary signal.

Outlier auto-downweight

Methods >50% from median get ½ weight

Robust-statistics safety net: any method whose output strays more than 50% from the median of the other three methods has its confidence weight halved when computing the blended mid-point. Prevents a single bad extrapolation from dragging the headline.

Recency decay for secondary trades

180-day half-life (e⁻ᵈ/¹⁸⁰)

A trade from 30 days ago counts ~5× more than one from 180 days ago. Tunable; some platforms use shorter half-lives.

Tax estimate

US federal only, single filer

Uses 2024 US federal brackets, ignoring state tax, NIIT, AMT credit recovery, and any other deductions. Treat as a directional sanity check, not a tax bill.
