Lei Jun still owns about 23.26% of Xiaomi’s total issued shares based on Xiaomi’s late-2025 disclosure, after buying more Class B shares that month. That works out to roughly 4.06 billion Class A shares and 1.99 billion Class B shares in his interest.

What that means

  • He remains Xiaomi’s controlling shareholder in practice because the company uses a dual-class structure that gives him outsized voting power.
  • One source also says he controls 61.1% of Xiaomi’s voting rights through Class A shares.

Latest public snapshot

  • Ownership stake: 23.26%
  • Class A shares: 4,063,148,182
  • Class B shares: 1,993,631,456

TL;DR

Lei Jun still owns about a little under a quarter of Xiaomi on a share- count basis, and he controls far more than that in voting power because of Xiaomi’s share structure.
