Summary
Jeremy Grantham, the celebrated co-founder of investment management firm GMO and recognized authority on asset bubbles, delivered a sweeping critique of Bitcoin during a June 27, 2026 appearance on CNBC's "Squawk Box," reiterating and expanding upon his long-held conviction that cryptocurrency lacks fundamental value. Grantham characterized Bitcoin as a "useless, speculative mechanism" without intrinsic merit, arguing the asset has failed to justify its existence as either a practical payment system or a reliable hedge against economic uncertainty.
The investor's core argument centers on Bitcoin's practical uselessness and volatility. Grantham noted that cryptocurrency has not outperformed during bull markets and emphasized that real-world adoption remains negligible—consumers do not use Bitcoin for routine transactions such as grocery purchases, and institutional participants have not embraced it for serious financial trading. Instead, he contended that Bitcoin's primary utility has been facilitating illicit money transfers by "crooks." This functional vacuum, combined with price swings that have occurred "for no particular reason in a strong economy," undermines any claim to serve as a stable store of value, according to Grantham.
Rather than predicting a dramatic crash, Grantham adopted a more measured long-term outlook, suggesting Bitcoin will "dwindle away with a whimper" over decades as its lack of intrinsic utility becomes increasingly apparent to market participants. He contrasted Bitcoin's trajectory with gold, which has delivered consistent returns over extended periods despite periodic pullbacks from historical highs. The timing of Grantham's remarks is notable given Bitcoin's 52% decline from its October 2025 peak, with the asset currently hovering below $60,000—a position many analysts expect to persist for several additional months given historical volatility patterns in cryptocurrency cycles.
Grantham's skepticism extends beyond a simple valuation disagreement; his critique questions whether Bitcoin can fulfill any of the roles traditionally assigned to financial assets. Without productive cash flows, utility in commerce, or macroeconomic stability properties, Grantham positions Bitcoin as a speculative instrument with structural weaknesses that will ultimately render it economically irrelevant, distinguishing his view from those investors who remain bullish on cryptocurrency adoption and long-term price appreciation.
