Harvard economist Kenneth Rogoff, on August 19, 2025, admitted on X that his 2018 Bitcoin prediction of a $100 valuation was incorrect, citing unexpected regulatory inaction.

Rogoff’s admission highlights the underestimated regulatory impact and Bitcoin’s rise as a transaction medium, stirring significant reactions in cryptocurrency markets.

Kenneth Rogoff, a prominent Harvard economist, acknowledged a forecast error he made in 2018 regarding Bitcoin falling to $100. Bitcoin’s price soared beyond $124,000, contradicting his prediction. Rogoff shared these reflections on his official X account.

Rogoff mentioned he was overly optimistic about United States’ regulatory measures and Bitcoin’s potential to compete as a global transaction medium. He noted his oversight concerning the impacts of regulatory inaction and the underground economy.

The revised prediction by Rogoff demonstrates the growing involvement of institutional investors and a shift in perceptions of Bitcoin’s value. This has led to an influx of capital, propelling Bitcoin to unprecedented levels.

Financial analysts suggest that federal inaction and increased adoption by major corporations have accelerated Bitcoin’s acceptance. Additionally, Bitcoin has become integral to the twenty-trillion-dollar global underground economy.

Rogoff’s acknowledgment resonates across the financial landscape. Regulatory behaviors and the burgeoning black market usage of Bitcoin seem to have profoundly influenced its trajectory, contradicting prior expectations.

Experts speculate on the future regulatory, market, and technological impacts due to Bitcoin’s surging valuation. Historical trends suggest potential for further volatility, driven by regulatory responses or shifts in global economic dynamics.

Kenneth S Rogoff, Maurits C. Boas Chair of International Economics at Harvard University, “Almost a decade ago I was the Harvard economist that said that bitcoin was more likely to be worth $100 than 100k. What did I miss? I was far too optimistic about the US coming to its senses about sensible cryptocurrency regulation; why would policymakers want to facilitate tax evasion and illegal activities?”: source
