Robot factories and hypersonic missiles: JPMorgan Chase’s first $5 billion of defense investments

The financial institution, which initially stated last year that it would allocate $10 billion into startups over the course of a decade, is now open to expanding the program beyond that initial budgetary ceiling, according to JPMorgan co-President Doug Petno during an interview.

Todd Combs, the former Berkshire Hathaway executive and longtime investment lieutenant to Warren Buffett who now leads the JPMorgan group tasked with driving these strategic startup investments, has hit the ground running since transitioning to the bank. Petno noted that Combs has done an exceptional job positioning the firm within several high-potential companies that align with the core mission of the overarching project.

While the vast majority of these early-stage investments remain undisclosed, a pair of known corporate stakes serves as a clear indication of the initiative’s core mission. JPMorgan has taken direct equity stakes in defense-related startups Hadrian and Castelion, companies designed to support American industrial capacity during an increasingly complex and dangerous era of geopolitics.

The launch of the initiative a year ago by JPMorgan CEO Jamie Dimon was directly prompted by mounting international turbulence, including ongoing wars in Ukraine and the Middle East, alongside persistent trade friction with China. These escalating geopolitical divides have exposed vulnerabilities in the cross-border flow of energy and essential components required by domestic industries and defense infrastructure, prompting the bank’s leadership to act on a grand scale.

Dimon placed Petno, widely recognized as one of the two key internal candidates considered possible successors to lead the banking giant, in charge of overseeing the entire investment project. Meanwhile, Combs, who previously served on JPMorgan’s board of directors, reports directly to Dimon, bridging traditional Wall Street heavyweight management with venture-style capital allocation.

The breadth of the project extends far beyond traditional defense, manufacturing, and supply chain logistics, encompassing frontier technologies as well as the pharmaceutical and health-tech sectors.

Petno observed that there is an abundance of interesting companies actively working to solve complex systemic problems domestically. These early venture-stage and advanced manufacturing firms have successfully engineered ways to build essential industrial capabilities directly within the United States, reducing and eventually eliminating heavy reliance on overseas trading partners.

In August, the banking titan helped spearhead a massive $1.4 billion funding round for Hadrian, an enterprise that builds automated factories utilizing advanced robotics and artificial intelligence to manufacture precision parts for the defense, aerospace, and maritime sectors. Hadrian’s founder has noted that a single automated factory run by the startup in California operates with a ratio of 10 robots for every human employee.

During that same month, JPMorgan also participated in a monumental $1 billion funding round for Castelion, a defense startup whose flagship product is a cost-effective hypersonic missile system named Blackbeard. Castelion was founded in late 2002 by a dedicated team of former SpaceX engineers seeking to modernize defense manufacturing through rapid innovation and scalable production pipelines.

Expressing his enthusiasm for the long-term potential of these enterprises, Combs emphasized the bank’s strategic vision in a statement released Monday. He noted that the primary approach centers on finding generational companies and establishing enduring partnerships designed to last for decades, adding that putting more than $5 billion to work in the very first year demonstrates the sheer volume of exceptional businesses currently building industries capable of strengthening critical domestic supply chains.

Risky Business?

For JPMorgan Chase, deploying billions of dollars of direct equity investments into nascent and unproven companies represents a significant departure from its historical role as a commercial lender, financial advisor, and underwriter.

Prior to the launch of the defense and security initiative, the bank had progressively moved away from taking direct equity stakes in startups, which inherently carry considerable financial risk due to their reliance on unproven technologies and volatile market adoption curves. More than a decade ago, JPMorgan spun off its private equity division, known as One Equity Partners, to distance itself from direct corporate ownership models.

Operating within its more traditional financial framework, JPMorgan has simultaneously financed and facilitated more than $230 billion for various industries that directly support American national interests, according to internal bank data.

This parallel track of the overarching security and resiliency project—which aims to reach a staggering $1.5 trillion in total financing and facilitation over the course of a decade—is led by Jay Horine, a former co-head of investment banking at the firm.

To execute this expansive vision, JPMorgan carefully assembled a dedicated team consisting of roughly three dozen specialized bankers, who are actively supported by hundreds of additional professionals drawn from across different divisions of the firm. This operational scaling has coincided with the expansion of the initiative into key international allied markets, including Europe and Canada.

According to Petno, the bank’s dedicated internal bankers are actively mapping comprehensive distribution lines for essential products—ranging from submarines and advanced aircraft to missiles and critical electronics—to identify vulnerable domestic suppliers that may currently lack the capital, infrastructure, or operational capacity to meet surging future demand.

Furthermore, Petno noted that JPMorgan maintains regular communication and active dialogues with leadership at the U.S. Department of Defense and the Department of Commerce, ensuring that the private sector investment strategy remains closely aligned with shifting government priorities and national security needs.
