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. xAI grants ISO/NSO with strike prices from $180–$230.
Secondary market premium
The secondary market is pricing OpenAI at a +0% premium over its last primary round ($852B → $853B). xAI trades at +0% over its last round ($250B → $250B). 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). xAI runs at $0.5B ARR, growing +300% YoY (hypergrowth). Revenue growth rate matters for equity because it drives the peer-multiple valuation — the method most correlated with exit multiples.
