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. Mistral AI grants ISO/NSO with strike prices from $35–$55.
Secondary market signal
The secondary market prices OpenAI at +27% vs its last primary round ($852B → $1.1T, source: Forge). Mistral 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). Mistral AI runs at $0.4B ARR, growing +1500% YoY (hypergrowth). Revenue growth rate matters for equity because it drives the peer-multiple valuation — the method most correlated with exit multiples.
