Every line item, every source, every assumption. The number on the front page is the sum below — public positions repriced live, private marks pinned to their last round. Last methodology review: June 12, 2026 (SPCX IPO day).
SpaceXSPCX · PUBLIC AS OF TODAY
—
5.25B shares × — live
Musk's stake was worth $866.5B at the $135 IPO price per the updated prospectus — ~5.25B share-equivalents at his disclosed ~42% economic stake. SpaceX now contains xAI (merged Feb 2026 at a $250B xAI mark) which itself absorbed X Corp in March 2025 — so the old xAI / X line items live inside this one. IPO: $135/sh, $1.77T valuation, Nasdaq, June 12 2026.
TeslaTSLA · PUBLIC
—
~717M share-equivalents × — live
~413M common shares (Revocable Trust) plus 304M options from the 2018 package, restored by the Delaware Supreme Court in Dec 2025. The 2025 CEO Performance Award adds up to 423.7M more, vesting on Tesla market-cap milestones ($2.0T–$8.5T). All 12 tranches currently unvested. Aggregate ~$7B exercise cost on the 2018 options not netted; flagged here instead of hidden.
The Boring CompanyPRIVATE · STATIC MARK
$6.3B
~90% × $7.0B estimated mark
Last priced round: $5.675B (Series C, Apr 2022). $7B reflects secondary-market estimates since; we hold it static and label it. Refreshed only when a new round prices.
NeuralinkPRIVATE · STATIC MARK
$4.5B
~50% × $9.0B (Series E, Jun 2025)
$650M Series E (June 2025) at a $9B valuation. Musk's exact stake is undisclosed; ~50% is the consensus estimate and it moves the total by <0.5% either way.
Cash & other liquid
$5.0B
Estimate. He sold ~$40B of TSLA in 2021–22 (taxes + the X acquisition consumed most of it) and famously calls himself "cash poor." Anything between $2B and $10B changes the headline number by a rounding error.
Margin loans & liabilities
−$7.5B
Estimate of TSLA pledged-share-backed borrowings and other personal liabilities. Most outlets net some version of this; the actual number is undisclosed.
Why our number ≠ Forbes ≠ Bloomberg
Forbes prints ~$1.10T; Bloomberg ~$1.11T (June 2026). They apply liquidity discounts, net out option exercise costs and estimated taxes, and reprice once daily. We show gross paper math, repriced every tick, and tell you exactly that. Transparent > conservative.
