OpenAI vs Scale AI: employee equity compared
Secondary market prices, valuation trajectory, equity structure, and liquidity outlook for employees choosing between OpenAI and Scale AI.
OpenAI
Maker of ChatGPT, GPT-5, Sora and the OpenAI API.
IPO highly anticipated, likely 2026–2027 given massive scale. One of the most closely watched pre-IPO names in tech.
High-growth AI play; PPU (no exercise decision needed); fast-moving valuations reward timing
Scale AI
Data-labeling and AI infrastructure platform. Meta acquired a 49% stake at $29B implied valuation (Jun 2025). Secondary trades at ~50% discount reflecting client departures (Google, OpenAI, xAI) post-deal.
IPO uncertain. Meta's 49% stake limits independence; Founder Alexandr Wang moved to Meta as Chief AI Officer. Liquidity most likely via further Meta acquisition or tender offer.
Deep US government/defense contracts; ISO/NSO options; secondary at steep discount to primary — timing matters
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 signal
The secondary market prices OpenAI at +27% vs its last primary round ($852B → $1.1T, source: Forge). Scale AI has no recent verified secondary signal. A higher secondary premium typically 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.
