The main risks are not that the technology is fake, but that time, concentration and supply-chain control work against the thesis. Ambarella depends on a small number of
advanced-node manufacturing paths, one distributor accounted for a very large share of revenue, and newer edge-AI categories still require long qualification cycles before they become meaningful revenue. If
CV7/
N1 ramps slip, trade rules tighten, or customers consolidate onto larger full-stack vendors, revenue can still grow without producing the scale or multiple expansion needed for a big equity outcome.
