Equity comp at SpaceX

• Twice a year (typically May and November), SpaceX organizes a window where employees can sell some of their vested shares to approved outside buyers. The industry name for this is a 'tender offer'. Because SpaceX is unlikely to IPO soon, these twice-yearly events are the main way employees can convert SpaceX equity into cash. Most planning questions for SpaceX employees ('when can I sell?', 'how much will I get?') really come down to the next tender's pricing and how many shares the company lets each employee sell.
• RSUs use double-trigger vesting. Two things must both happen before the shares are yours: (1) the normal time-based vesting completes, and (2) the company has a liquidity event (an IPO or an acquisition). Until both happen, you do not yet own the shares and you do not owe tax on them.
