Equity comp at xAI

• In February 2026, SpaceX acquired xAI in an all-stock deal. Each xAI share converted into 0.1433 SpaceX shares, converting all xAI equity (vested options, unvested grants, RSUs) into SpaceX equity at the same ratio. For equity planning, employees who held xAI grants now hold SpaceX grants. Standard tax treatment (ISO for incentive stock options, NSO for non-qualified, or ordinary income on RSU vest) carried forward through the conversion with terms adjusted proportionally. Liquidity now depends on SpaceX's twice-yearly tender offer (a company-organized window where employees can sell vested shares to outside buyers) calendar and SpaceX's planned IPO, not any independent xAI path.
