SpaceX's valuation math is linear: off a base of 13.08 billion shares (Class A + B, ex-overallotment) — the count behind the $1.77T valuation at the $135 offer — each $1 of price adds roughly $13.1B of market cap. The stock opened sharply higher and already trades near $168, a ~$2.19T cap that ranks it 7th in the world, just behind TSMC and ahead of Broadcom.
Every dollar, $13B of market cap
At the live price of $168 (~$2.19T), SpaceX opened +24% on debut, past Aramco and just behind TSMC. The milestone rungs show the exact price needed to overtake each peer at current caps: Amazon ~$195 (a $2.54T cap, +44% vs the offer), Microsoft ~$220 ($2.88T, +63%), Apple ~$328 ($4.29T, +143%), Alphabet ~$336 ($4.40T, +149%), and the world's #1, Nvidia, at ~$380 ($4.97T, +181%). Overtaking Amazon is just +16% from the live price; clearing Apple takes ~2x, and becoming the world's most valuable company ~2.3x. Peer caps are as reported Jun 12, 2026, and an over-allotment of +83.3M shares, if exercised, lifts the base ~0.6% and every figure with it.
