Mingxing "Star" XuNet Worth Estimate

Estimated Range$3.0B - $5.5B$3,000,000,000 - $5,500,000,000

Mingxing "Star" Xu is best estimated at roughly $3.0 billion to $5.5 billion, with a wider plausible range of about $1.5 billion to $8.0 billion. The estimate is driven by his presumed stake in OKX, which was reportedly valued at $25 billion in a 2026 ICE investment.

Estimate

Current Assessment

The strongest public evidence is the March 2026 report that Intercontinental Exchange invested in OKX at a $25 billion valuation. Xu is identified as OKX's founder and CEO, but his exact ownership is not public. The estimate therefore applies a founder-stake range to that valuation and discounts for private-company liquidity, taxes, and regulatory risk. OKX's proof-of-reserves page and market-data sources support that the exchange remains large and active, but customer assets, reserves, and trading volume are not personal wealth.

Key caveats

  • Xu's OKX ownership percentage is not publicly disclosed.
  • The estimate does not count OKX customer reserves, trading volume, or company revenue as personal assets.
  • Company-level penalties are treated as valuation risk, not personal debt.
  • Potential holdings in OKG/Leap, tokens, real estate, or other assets were not verified enough to include.

Evidence gaps

  • OKX cap table or shareholder registry
  • Current OKG/Leap stake value
  • Xu's personal token holdings and liquid assets
  • Personal liabilities and tax exposure

Uncertainty Drivers

  • No public OKX cap table or Xu ownership percentage was located.
  • OKX is private, so revenue, profit, preferences, debt, and investor rights are not visible.
  • The ICE investment terms and stake size were not disclosed in the WSJ item.
  • Crypto exchange valuations can move sharply with market conditions, trading volumes, enforcement risk, and jurisdictional access.
  • Xu's personal token holdings, cash, real estate, tax exposure, and liabilities were not found.
