Key differences for employees

Equity structure

OpenAI grants PPU — a profit participation unit unique to OpenAI. No strike price, no AMT risk. You receive cash or shares at distribution events. Scale AI grants ISO/NSO with strike prices from $35–$50.

Secondary market premium

The secondary market is pricing OpenAI at a +0% premium over its last primary round ($852B$853B). Scale AI trades at +4% over its last round ($13.8B$14.4B). A higher secondary premium signals stronger investor demand and potentially better near-term liquidity for employees looking to sell.

Revenue and growth

OpenAI runs at $24B ARR, growing +60% YoY (fast). Scale AI runs at $1B ARR, growing +70% YoY (fast). Revenue growth rate matters for equity because it drives the peer-multiple valuation — the method most correlated with exit multiples.

Liquidity timeline

OpenAI: IPO highly anticipated, likely 2026–2027 given massive scale. One of the most closely watched pre-IPO names in tech.

Scale AI: IPO plausible 2027–2029 if growth trajectory holds. Liquidity may come via tender offer or strategic acquisition before listing.

How do I know if my OpenAI or Scale AI equity is fairly priced?
Compare your grant's implied per-share value against the secondary market price. If investors are paying a premium on Hiive or Forge over the last primary round, that's a signal of strong demand. PrivatePulse shows you the gap between your 409A and what the secondary market says.
Can I sell my OpenAI or Scale AI shares on the secondary market?
Secondary market transactions (Hiive, Forge, Caplight) require accredited investor status and your company's consent — most private companies have right-of-first-refusal (ROFR) provisions. Tender offers, when available, are typically the most accessible path to partial liquidity for employees.
