Base case is our central scenario. Bear and bull cases show how uncertainty around private holdings, retained proceeds, taxes and liabilities can move the estimate.
Rankings use the current base-case estimate and show the wider bear-to-bull range on the full list.
Switch scenarios to see how the total and each component move together. The bars show each positive component's share of the estimated assets in that scenario, not audited holdings.
ATP’s 2026 media guide lists $21,354,778 of prize money for Alcaraz in the 2025 season. A single U.S. Open title that year carried a $5 million winner’s check.
Those are large flows for a player still early in his career, but tennis has meaningful taxes and professional costs. The model therefore retains only a portion of cumulative prize earnings.
Forbes cited $32 million of off-court earnings alongside $10.3 million on the court in its 2025 discussion of the prior year’s tennis earnings.
That commercial platform supports a second wealth component, while the lack of public balance-sheet data keeps the overall range wide.
Sources[3][2][1]A reported salary, company sale or brand valuation is not automatically current personal wealth. We show the pieces that can be tied to retained evidence and keep historical flows separate.

Sources[2]Prize money and endorsements are modeled separately as historical gross inflows. The estimate applies a substantial haircut for taxes, coaching, representation, travel and spending, and it does not assume that future earning power already exists as current wealth.

ATP records show $21.35 million of prize money in 2025 alone, while Forbes reporting places career prize money above $50 million during 2025. The model applies a retention range after taxes, coaching costs, representation, travel and spending.
Sources[3][2]Forbes reported $32 million of off-court earnings in its 2025 coverage of the prior year’s tennis earnings. The model treats those gross commercial flows separately from prize money and does not assume undisclosed ownership interests.

Initial Grizzly Bulls estimate published with tennis prize money separated from endorsement and commercial income.
This is the first retained snapshot, so there is no earlier comparable Grizzly Bulls estimate to show yet.
