Kaio César

In January 2026, reports indicated that Corinthians and Atlético-MG made loan offers that included a €6 million purchase option for 50% of the player's rights, implying a €12 million total valuation. During these negotiations, Al-Hilal's asking price for a loan fee was reportedly €500,000, with some reports valuing the final deal at €1 million. His market value was estimated by Transfermarkt at €4.5 million in January 2026, down from €5.0 million in August 2025. The player's most recent permanent transfer was in January 2025, when he moved from Vitória SC to Al Hilal for a fee of €9.0 million. Prior to that, in January 2025, he moved from Coritiba to Vitória SC for €4.2 million.

Our valuation for Kaio César is primarily driven by two key figures. The first is his completed transfer from Vitória SC to Al Hilal for €9.0 million in January 2025. The second is the recent January 2026 loan deal to Corinthians, which reportedly includes a purchase option of €6.0 million for 50% of his rights, implying a full valuation of €12.0 million. This option figure, also reportedly offered by Atlético-MG, establishes a clear upper bound, while his most recent transfer fee provides a solid floor.
