Key Takeaways
- • Masayoshi Son, founder of SoftBank, personally invested in bitcoin in late 2017 near its $20,000 peak and sold early 2018 after the market collapsed, realizing a loss exceeding $130 million.
- • Son's bitcoin investment followed a recommendation from a "bitcoin evangelist" whose investment firm SoftBank had acquired earlier in 2017, demonstrating how institutional decision-making can be influenced by external advisors during market euphoria.
- • The trade illustrates that even sophisticated investors with strong long-term track records—Son leads the $100 billion SoftBank Vision Fund with stakes in major tech companies including Uber and WeWork—are vulnerable to speculative asset bubbles during peak sentiment periods.
- • Son sold his position as bitcoin traded around $5,000 in early 2018, locking in losses as the digital currency declined approximately 75% from its December 2017 peak.
Summary
Masayoshi Son, the billionaire founder of SoftBank Group, personally lost over $130 million on a bitcoin investment made during the peak of the 2017 cryptocurrency boom. According to the Wall Street Journal, Son purchased bitcoin in late 2017 when the digital currency reached its then-record high near $20,000 in December. He subsequently sold his position in early 2018 as bitcoin's value collapsed, crystallizing substantial losses as the asset traded around $5,000 at the time of sale.
The investment decision was reportedly made following recommendations from a "bitcoin evangelist," whose investment firm SoftBank had acquired earlier in 2017. While the exact volume of bitcoin Son purchased remains undisclosed, the magnitude of the loss—exceeding $130 million—indicates a substantial personal commitment to the speculative asset during the height of market euphoria surrounding digital currencies and initial coin offerings.
Despite his reputation as a disciplined long-term investor, Son's bitcoin bet reflects a pattern of aggressive, high-conviction trades made on relatively limited due diligence. Son is widely known for committing hundreds of millions of dollars to companies after brief meetings with founders and executives. However, his venture capital expertise through SoftBank—which manages nearly $190 billion in net assets and has deployed capital into Uber, Nvidia, Flipkart, and WeWork—did not translate to success in the highly speculative cryptocurrency market.
This episode underscores how even institutional investors with sophisticated deal-making capabilities and significant resources remain susceptible to momentum-driven investment decisions during bull markets in emerging asset classes. The loss occurred as bitcoin experienced a severe correction from its 2017 peak, a common pattern in speculative bubbles where late-stage retail and institutional enthusiasm coincides with the market peak.
