Grayscale: De-risking, not quantum fears, drove Bitcoin fall

Grayscale Research concluded in a May 2026 note that broad de-risking from frontier technology stocks, not immediate fears about quantum computers, was a primary driver of Bitcoin’s recent decline. Public quantum computing companies moved in close correlation with Bitcoin over recent months, the firm found.

Zach Pandl, Grayscale’s head of research, tracked the price action of listed quantum firms and reported that shares of IonQ, Rigetti and D-Wave each fell more than 25% year to date. Pandl argued that if markets were pricing a near-term cryptographic threat from quantum computers, those companies’ shares would likely have risen on expectations of increased commercial demand; instead, they fell alongside Bitcoin.

Grayscale attributes the losses to a wider pullback in growth-oriented portfolios. The note cites investor concerns about artificial intelligence disruption and tighter macroeconomic conditions as factors prompting traders to exit riskier, speculative assets. The firm also referenced heavy outflows from spot Bitcoin exchange-traded funds and a broader risk-off mood that pushed Bitcoin toward roughly $85,000 at the selloff low.

On the topic of cryptographic risk and network upgrades, Pandl wrote that the threat from quantum computers is probably not the main factor weighing on Bitcoin’s price and that valuations can recover before a full post-quantum upgrade. Grayscale supports faster post-quantum readiness across major blockchains but identified governance-coordinating network changes-as a bigger hurdle than engineering work. The note added that investors do not need to wait for a complete post-quantum upgrade before taking exposure to Bitcoin, while cautioning that any recovery may be gradual as traders balance broader bear-market signals.

The note said quantum processors have made technical progress, but the firm found no market evidence that breakthroughs capable of compromising widely used cryptography have emerged in a way markets treat as an immediate existential risk to Bitcoin.
