You want a US-listed, pure humanoid, multi-bagger name — like buying NVIDIA early. Plainly: it's basically an empty set. The hardest chokepoints are almost all private, China/Japan-listed, or big-company internals. The US-buyable pure-plays are pricey and cash-burning: TSLA diluted (Optimus ~14%), Aurora burns most, Pony eats an ADR discount. Manage them as disciplined options, not a core bet.
