Tesla AI5
A line that does not exist yet, carried at zero across every reported quarter and starting in 2027. Tesla's AI5 is a roughly half-reticle inference die that Musk has said will be built at TSMC, two per car, against a stated ambition of two million cars a year. TSMC has never named Tesla as a customer, never mentioned AI5, and publishes no wafer price, so every number on this line is an outside estimate rather than a disclosure. It is here to make one question answerable on the page: what would a flagship automotive AI win actually be worth to a company running at $45bn a quarter? The answer, on the arithmetic below, is about half a percent of revenue - which is itself the finding.

Assumptions & reasoning
- Zero in every reported quarter, by construction. Tesla already buys silicon from TSMC and that revenue is inside the Automotive and HPC lines already; this vertical is the INCREMENTAL AI5 ramp above the current run rate, and reading it any other way double-counts.
- The arithmetic: two million cars a year at two dies each is four million chips, or one million a quarter. At roughly $150 of TSMC revenue per chip - about $22k a wafer over some 175 good half-reticle dies, plus packaging - that is about $150M a quarter, or $600M a year.
- The chip count grows toward 1.8 million a quarter, which is where Optimus and training clusters would take it. At $150 a chip that is $270M a quarter. A reader who wants the $250M a quarter that circulates for this programme is implicitly assuming roughly six to eight million AI5 dies a year, which is cars plus everything else, not cars alone.
- At its peak this line is about half a percent of TSMC revenue and moves fair value by cents. That is the point of carrying it: a flagship automotive design win at a company this size is a rounding error, and the model says so explicitly rather than leaving it to intuition.
