US Invests in Quantum Computing as Bitcoin Risks Rise

The US government takes stakes in quantum firms like IBM and D-Wave as new research suggests Bitcoin's encryption could be vulnerable sooner than expected.

The U.S. Department of Commerce has finalized agreements with nine quantum computing companies, marking a strategic shift where Washington is directly acquiring minority stakes rather than just providing subsidies. This move aims to reduce dependence on China for critical technologies.

According to Bloomberg, IBM is set to receive the largest share of funding—$1 billion for its new Anderon unit, which will manufacture quantum chips on U.S. soil. IBM will also contribute an additional $1 billion in equity to the project. GlobalFoundries is slated to receive $375 million for its new Quantum Technology Solutions division, while D-Wave, Rigetti, PsiQuantum, and Infleqtion will each receive approximately $100 million.

The announcement triggered a rally in quantum-related stocks, with shares of D-Wave and Rigetti surging by more than 20% in a single trading session.

The Quantum Race Becomes Geopolitical

Washington’s decision comes as quantum technology transitions from an academic experiment into a strategic industry with profound implications for cybersecurity, defense, and the global financial system.

Market reactions were further intensified by two key scientific publications that dramatically lowered the projected hardware threshold required to break Bitcoin’s cryptography.

Google Quantum AI published a study suggesting that fewer than 500,000 physical qubits could be enough to compromise the ECDSA cryptography used by BTC. Previous estimates had placed that requirement between 10 million and 30 million qubits.

Separately, research from Caltech indicates that a neutral-atom quantum system with just 26,000 qubits could recover a private key from a public key using Shor’s algorithm in about 10 days.

These findings have shifted sentiment within the financial sector, where quantum risk is increasingly viewed as a tangible systemic issue rather than a distant academic threat.

Wall Street Begins Hedging Against Quantum Risk

Analysis from Citi suggests that approximately 6.9 million BTC—roughly 35% of the circulating supply—could be vulnerable to sufficiently advanced quantum machines. This includes early addresses with publicly revealed keys, inactive wallets, and the estimated 1.1 million BTC attributed to Bitcoin’s creator, Satoshi Nakamoto.

Some institutional investors are already taking defensive measures. Jefferies has completely removed its 10% BTC exposure from its model pension portfolio, specifically citing long-term quantum risk as the reason.

In tandem, the crypto industry is seeing more active discussions regarding the urgent need to transition toward post-quantum cryptography.

Bitcoin Faces a Political, Not Just Technological, Crisis

To implement quantum-resistant protections, Bitcoin would require a massive soft fork and a widespread migration to a new type of address. Some proposals suggest a limited time window, after which vulnerable addresses could be frozen or excluded from the network.

Such a move would challenge one of Bitcoin’s core principles: network immutability and censorship resistance.

This transforms the quantum threat into more than a technical hurdle; it represents perhaps the most significant governance crisis in Bitcoin’s history. The industry is now forced to debate whether protecting the network justifies violating its own fundamental rules.
