Sources: SoftBank is investigating who was behind the smear campaign that called for the ouster of its top execs Nikesh Arora and Alok Sama
Series of letters to board called for removal of Nikesh Arora and Alok Sama; ‘sabotage’ effort also involved media leaks, complaint to SEC
Context & Ripple Effects
This investigation lands mid-arc in a long-running SoftBank succession drama. Nikesh Arora had been groomed as Masayoshi Son's heir before stepping down as president in 2016, and Alok Sama was a key dealmaker alongside him — so anonymous board letters demanding both men's removal strike at the heart of who controls Son's empire.
The tactics described — board letters, media leaks, an SEC complaint — prefigure the internecine warfare that surfaced again years later, when Vision Fund head Rajeev Misra was accused of sabotaging rival executives and SoftBank ultimately removed three senior executives, including Misra, from its board amid governance pressure.
First-order effects
- SoftBank must now run an internal probe into the letters, leaks, and SEC complaint while Nikesh Arora and Alok Sama remain under public attack — forcing the board to defend its own top brass against an unidentified internal adversary.
- Whoever authored the campaign faces exposure: the investigation makes continued anonymous attacks riskier for any insider involved.
Second-order effects
- The SEC complaint embedded in the campaign draws regulators into an internal power struggle, seeding the federal scrutiny that later surfaced when the SEC confirmed it was investigating SoftBank.
- Rival factions around Masayoshi Son get put on notice: if the probe identifies the authors, the balance of influence over Son's succession and the Vision Fund's leadership shifts accordingly.
Third-order effects
- If the pattern holds — anonymous attacks in 2018, sabotage accusations in 2020, board purges the same year — SoftBank's governance problem looks structural rather than episodic, pushing a founder-controlled conglomerate toward formal checks on executive infighting.
- Persistent internal warfare at the top threatens the stability of the $100B Vision Fund's leadership, making outside limited partners' governance demands harder for Son to resist.
The trend: SoftBank's leadership battles are escalating from anonymous smear campaigns into repeated governance crises that keep forcing Masayoshi Son to restructure his inner circle.
