AMPX doubled in a few trading days.
A tiny battery company with under $12M in quarterly revenue is suddenly trading like it’s discovered perpetual motion — or at least something Wall Street believes in.

This piece unpacks what’s real behind the move:
Surging revenue
An elusive but growing $100B+ market
Actual shipments to defense and aerospace buyers
And yes, the kind of story retail traders love — a moonshot narrative backed by real tech.
But does the chart justify the valuation?
Can margins catch up with momentum?
Let’s break it down — from the beginning.
