US Invests $2 Billion in Quantum Computing Amid Rising Security Fears

The U.S. Commerce Department is injecting $2 billion into the quantum computing industry to spur domestic innovation, a move that comes just as top credit rating agencies flag the technology as a systemic threat to the global financial system. The funding, part of the 2022 CHIPS and Science Act, will be distributed among nine companies, with the government taking equity stakes in each.

"From a risk standpoint, the more immediate question is how institutions operating in an increasingly digital environment are positioning themselves against the cryptographic implications of quantum advances — a threat that is not immediate, but is potentially systemic," Rajeev Bamra, associate managing director of Moody’s Digital Economy Group, told Barron's.

The funding round's largest beneficiary is IBM, which will receive $1 billion to develop America's first purpose-built quantum chip foundry in Albany, New York, through a new entity named Anderon. Other significant awards include $375 million for chipmaker GlobalFoundries, and $100 million each for D-Wave Quantum, Rigetti Computing, and Infleqtion. The news sent shares of D-Wave (QBTS) and Rigetti (RGTI) up 14.22% and 19.87% respectively.

The investment highlights a sharp conflict: while the U.S. government is fostering the technology's growth, Moody's warned in a May 2026 report that a powerful quantum computer could jeopardize the world's digital financial infrastructure. Citing research from the Citi Institute, the agency noted a quantum breach targeting payment systems could cause between $2 trillion and $3 trillion in economic losses on what experts call "Q-Day"—the moment a quantum computer can break modern encryption, a milestone some predict could arrive as soon as 2028.

The 'Harvest Now, Decrypt Later' Threat

The danger is not entirely in the future. Security experts are increasingly concerned about "harvest now, decrypt later" attacks, where malicious actors are currently intercepting and storing vast amounts of encrypted data from banks, governments, and corporations. The intention is to hold this sensitive information until a sufficiently powerful quantum computer is available to decode it, unlocking everything from corporate trade secrets to national security intelligence. This tactic turns today's secure communications into a future liability, adding urgency to the development of quantum-resistant security measures.

Banks Race to Build Quantum-Proof Defenses

Major financial institutions are not waiting for Q-Day to arrive. JPMorgan Chase is actively testing post-quantum cryptography (PQC) solutions, designing "crypto-agile" systems that can be rapidly updated to defend against new threats. The bank's strategy is to create an infrastructure that can swap out vulnerable encryption standards as soon as a quantum threat becomes viable. Similarly, HSBC has been testing quantum key distribution (QKD), a technique that uses the principles of quantum physics to create theoretically un-hackable communication channels. The bank has already simulated foreign exchange transactions using this technology, demonstrating a proactive approach to securing its operations against the quantum threat. This preemptive spending on defensive technology represents a significant, growing cost center for the financial industry.

The U.S. investment is a strategic necessity in the global technology race, particularly as China aims to build a nationwide quantum network by 2030. However, by accelerating the development of quantum computers, the funding also shortens the timeline for the financial industry to prepare its defenses. The resulting stock gains for firms like D-Wave and Rigetti show investor enthusiasm for the technology's potential, but the multi-trillion dollar risk identified by Moody's underscores the immense challenge that lies ahead for the entire financial sector.
