How I Invest Podcast

A 22-year-old defence CEO on asymmetric warfare and deterring China

Key points

Key takeaways from the How I Invest Podcast interview with Mach Industries founder and CEO Ethan Thornton (October 2026):

Dropping out was never the risk. Thornton says the only real risk at the start was failing to build what the world needs; he had wanted to work on it since he was 16 and had already patented many of the designs before leaving MIT at 19.

From 20 experiments to a $3.7bn company. Mach deliberately ran like a lab, prototyping roughly 20 products (quadcopters, a hydrogen gun, an afterburning EDF and an electrolyser among them) during an MIT IAP month, because it had no confidence about what the Pentagon would buy; the company began the year valued at $470m and now sits near $3.7bn.

Asymmetry is the core thesis. Thornton defines asymmetric warfare as the Pareto edge of technology in any given fight, citing Ukraine's ability to out-innovate and strike Russian infrastructure despite smaller industrial capacity; Mach's portfolio spans stratospheric vehicles, hypersonics and deep-strike systems such as the Pike airframe.

Pentagon procurement is getting faster. Early on the Army said it would roll his Glide product into a 2035 plan; now, with stockpiles depleted, the Pentagon shows up asking what Mach can build, and is becoming faster, more objective and more collaborative out of necessity.

Fixed price over cost-plus. Thornton calls cost-plus contracting "another form of socialism" that rewarded spending over outcomes, arguing that SpaceX won precisely because the regime shifted towards capitalism and that asymmetric products are "asymmetrically cheap" to manufacture.

Deterrence, not winning, is the goal on Taiwan. He cites a roughly 12 per cent Polymarket probability of a China-Taiwan conflict by the end of 2027, argues most war games do not look good for defending Taiwan, and stresses that both sides would lose access to TSMC's advanced nodes if a war started.

Drones as tactical deterrence. Thornton's vision is unmanned systems delivering at the tactical level what nuclear weapons delivered strategically for decades, arming Taiwan, Japan, South Korea and Australia directly and indirectly to head off proxy wars.

Building the team on mission. He recruited best friend and now co-founder Ashton Bennett by writing a one-page plan together and being honest that success was unlikely; two Air Force ROTC friends dropped out to join, and others such as Dan later became build engineers on Pike.
