Estimate
Current Assessment
Most of Ishbia's wealth comes from his large stake in UWM Holdings, the parent of United Wholesale Mortgage. His controlling role in the Phoenix Suns and Phoenix Mercury is also material, but the team value must be adjusted for the Ishbia ownership group's share and for his brother Justin's separate participation. Forbes' 2026 estimate of roughly $9.1 billion fits the asset evidence and is used as a cross-check, not as the only basis for the estimate.
Key caveats
- The exact split of the Suns and Mercury stake between Mat and Justin Ishbia is not publicly clear.
- Current UWM share ownership and any pledged shares should be verified from the latest SEC filings.
- Known Suns and UWM legal disputes are unquantified and are treated as risk factors, not fixed liabilities.
Evidence gaps
- Latest direct SEC beneficial-ownership table for UWM.
- Personal financing terms for the Suns/Mercury acquisition.
- Detailed private assets, cash, and minority sports investments.
