The Trillion Dollar Vanishing Act

Spent a good chunk of the weekend reading about SpaceX’s stock losing a trillion dollars in valuation in a month, and I kept coming back to the same question: how do you lose something you never actually had?

That’s not a rhetorical trick, someone in the comments asked it plainly, and it’s a fair one. A trillion dollars of “value” evaporating doesn’t mean a trillion dollars existed anywhere except in a spreadsheet built on hype and a valuation nobody outside the company seemed to sanity-check. That’s the bit that gets me. Apparently the usual due diligence process, banks and underwriters actually running the numbers, got skipped in favour of letting Musk set his own price and building the prospectus to match. That’s not how markets are supposed to work, in theory. In practice, it seems to be exactly how markets work when enough momentum and mythology are attached to one bloke.

I’ve got no rocket science background, but I do work in tech, and I’ve sat through enough all-hands where leadership announces something “revolutionary” that’s actually a rebrand of last year’s roadmap. So I recognise the pattern here, just scaled up to a level that’s almost abstract. Starlink and the rocket business are genuinely impressive, reusable boosters changed the economics of getting things into orbit, and that’s not nothing. But somewhere along the way that got bundled with Twitter (sorry, X), with xAI, with a hyperloop-shaped graveyard of promises, and investors were asked to value the whole mess as if it were one coherent, endlessly growing thing. It isn’t. It’s a rocket company wearing several ill-fitting AI costumes.

What actually worries me isn’t Musk losing money on paper, plenty of people seem quite pleased about that, and I understand why. What worries me is the mechanism by which regular people’s retirement accounts ended up holding the bag. There’s a comment thread about SpaceX pushing to get included in the Nasdaq 100 and other indices before it would normally qualify, which meant a lot of index funds, the kind sitting quietly in super funds and 401(k) equivalents, bought in near the peak without anyone individually choosing to. That’s not speculation, that’s just how index investing works, and it’s usually a feature, not a bug. Except when the index itself gets gamed.

I think about my own super occasionally, usually with a mix of vague optimism and the specific dread of not actually knowing what’s in it. Most of us don’t. We trust that the system running quietly in the background is boring and sensible, tracking broad market performance rather than one man’s ego cycle. Finding out that a company with an unprofitable AI arm, a reputational mess of a social platform, and a rocket business worth maybe a fraction of its listed price got fast-tracked into the index that underpins a huge chunk of global retirement savings, that’s the part that should make people angry, not the schadenfreude of watching a trillion dollars vanish from someone who has more money than entire nations.

There’s a tension I can’t resolve here, and I won’t pretend I can. SpaceX the engineering project is legitimately remarkable. SpaceX the financial instrument is something else entirely, propped up by a cult of personality and a market that’s stopped pretending fundamentals matter much. Both of those things are true. I don’t know how you value a company at $1.75 trillion with a straight face, and I don’t know how you fix a system where the answer to “was this a good idea” only arrives after regular people’s savings have already been exposed to the fallout.

What I do think, and this is the closest I’ll get to a tidy conclusion, is that we keep confusing genuine technical achievement with sound financial judgement, as if being good at one thing means you’re trustworthy in all the others. Musk is good at rockets. He is not, on the evidence, good at self-driving timelines, social media, or knowing when to stop promising things he can’t deliver. Markets used to at least pretend to care about that distinction. Lately they don’t seem to bother.
