Quantum Computing Unlikely to Affect Crypto in 2026 – Grayscale

• Grayscale says quantum computing will not disrupt crypto markets in 2026.
• Bitcoin and Ethereum encryption remain secure under current technology.
• Blockchain networks can upgrade security before quantum risks become

The research team at the multibillion-dollar asset management firm Grayscale has played down fears that quantum computing could threaten cryptocurrencies in 2026. The firm argues the technology is not advanced enough to impact blockchain security or market activity.

Notably, Grayscale shared this view in its latest report, “2026 Digital Asset Outlook: Dawn of the Institutional Era.” 

The firm lists quantum computing among factors unlikely to influence digital asset prices, adoption, or institutional participation next year. Instead, it said investors should focus on near-term drivers such as regulation, capital inflows, and market structure rather than speculative technology risks.

Bitcoin and Ethereum Security Remains Intact

According to Grayscale, Bitcoin, Ethereum, and other major blockchains are unlikely to be affected by quantum computing in 2026. 

While the report notes that, in theory, a sufficiently powerful quantum computer could derive private keys from public keys, this level of technology is not expected until 2030 at the earliest.

Grayscale adds that most blockchains will eventually need to update their cryptography for post-quantum security. Still, research and community preparedness efforts are progressing, and this theme is unlikely to impact market prices in the near term.

Institutional Adoption Not Threatened by Quantum Advances

The report said quantum computing is unlikely to slow institutional participation in digital assets.

Grayscale expects banks, asset managers, and funds to continue increasing exposure through regulated products such as exchange-traded funds and custody platforms. The firm said concerns over quantum risk have not surfaced as a barrier in institutional decision-making.

Instead, regulatory clarity and operational infrastructure remain the primary focus for large investors entering the market.

Blockchain Security Can Evolve Before Quantum Becomes Practical

Grayscale also highlighted the adaptability of blockchain networks. Unlike static systems, blockchains can update software and adopt new cryptographic standards over time.

The report noted that research into quantum-resistant cryptography is already underway. These tools could be deployed before quantum computers reach a level that threatens existing encryption.

This ability to evolve reduces the likelihood of sudden or systemic disruption, according to the firm.

Why Grayscale Excludes Quantum Risk From 2026 Themes

Grayscale grouped quantum computing with other developments it believes will not shape digital asset markets in 2026.

The report instead focuses on themes such as stablecoin growth, tokenization of real-world assets, staking adoption, and expanding use of blockchain infrastructure. These areas, Grayscale said, are more likely to influence prices and capital flows.

Quantum computing, by contrast, remains a long-term research issue rather than an active market force.
