The Money Trap: Lost Illusions Inside the Tech Bubble
Insider memoir by SoftBank's former CFO
Summary
Alok Sama was chief financial officer and a senior dealmaker at SoftBank Group during the period of its largest transactions, and this memoir covers those years from inside.
The business material concerns the deals: the acquisition of ARM Holdings in 2016 for over thirty billion dollars, the Sprint position and the attempted merger with T-Mobile, the Nvidia stake, and the formation and early deployment of the Vision Fund with capital from Saudi and Emirati sovereign funds. Sama describes how Masayoshi Son makes decisions, which he presents as intuitive, fast and largely unconstrained by the analysis his own finance function produced.
The personal material concerns a smear campaign conducted against him and another executive, involving planted media stories and surveillance, which Sama attributes to internal rivalry and which was reported at the time. He writes candidly about the psychological effect and about his ambivalence toward the work. The book is a memoir rather than an analysis of SoftBank's returns, and it does not systematically assess whether the Vision Fund's strategy worked. Readers should note that Sama is writing about former colleagues and about a period whose outcomes are still disputed.
Key takeaways 6

- The ARM acquisition was pursued as a long-horizon bet on semiconductor architecture rather than on near-term returns.
- Vision Fund capital from sovereign investors carried structural obligations, including a preferred return, that shaped deployment pressure.
- Sama describes a smear campaign against senior executives that involved planted media stories and surveillance.
- Deal execution at scale depends on a small number of relationships rather than on institutional process.
- The book is a memoir and does not systematically assess whether the Vision Fund's strategy produced returns.
