$TSLA just had its best Q2 ever for deliveries, and made less money doing it. Revenue rose 26% YoY. Operating income fell 57%. On Tesla's own adjusted measure, the one that removes the SpaceX mark and stock compensation, profit fell 17%. The record volume is not what went wrong. Per unit margin is actually up YoY. But per unit margin held while everything built on top of it grew faster. Operating expenses rose 47% against revenue up 26%, and that is where the operating line went. The reported profit hides most of this. Net income looks close to flat, but more than two thirds of it is an unrealized gain on the SpaceX stake. Strip that and the other one offs and what's left is a fraction of last year on the same basis. Why it matters is what the car business is being asked to carry. Tesla has guided to spend roughly three times its historical rate this year, on factories and AI and robots that are not scheduled to earn their keep until later. Management said the spending grows for another two to three years, and told investors it is arranging debt facilities for up to $30B in borrowing capacity to help fund it. The car business got better this quarter. What it has to carry got bigger and faster. That is not a liquidity problem. The quarter moved the wrong way. The bet is that this spending pays off later. What would make you believe it?
