AMPX Rise: Will Amprius Keep Climbing After 200% YTD?

After a 200% surge in 2025, Amprius Technologies is trading like a moonshot — but with real customers, revenue, and defense contracts. Is the valuation justified?

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.

Last Friday, Amprius Technologies ($AMPX) was barely on anyone’s radar. By midweek, it hit a 52-week high, surged past $9, and drew comparisons to early-stage EV disruptors. So what happened?

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.
