Quantum Computing Unlikely to Impact Bitcoin, Crypto Prices in 2026: Grayscale
Quantum computers are not expected to pose a near-term risk to Bitcoin’s security or crypto market valuations in 2026, according to Grayscale’s 2026 Digital Asset Outlook. The report describes quantum computing as a long-term cryptographic challenge, but says the technology is unlikely to influence prices in the coming year. While theoretically, a sufficiently advanced quantum computer could break Bitcoin's public-key cryptography and forge digital signatures, experts and Grayscale analysts agree that such capabilities are not expected before 2030. Research into post-quantum cryptography will continue and likely accelerate, but the threat from quantum computing remains distant. Grayscale and many blockchain developers cite studies suggesting that cryptographically significant quantum computers are still years away, supporting the conclusion that quantum risk is not an immediate concern for crypto investors in 2026.
