Adam Karabec

Most recently, Olympique Lyon reportedly had a purchase option of €3.5 million in August 2025, which they decided not to exercise in June 2026. Prior to that, Hamburger SV had a purchase option during their loan, cited multiple times between March and August 2025 as being €4.2 million (potentially rising to €5 million with bonuses), which they also let lapse, deeming it too expensive. However, reports from June 2025 suggested HSV and Sparta Prague had agreed on a lower fee of €3 million. An early report from July 2024 also mentioned the HSV option was around €3 million. The player's Transfermarkt value was noted as €4 million in August 2025.

Our valuation is driven by two recent, but unexercised, purchase options which establish a clear ceiling on Adam Karabec's value: €4.2 million for HSV and €3.5 million for Lyon. The fact both clubs declined suggests his market value is lower. Our estimate is anchored by a June 2025 report of an agreed €3 million fee between Sparta Prague and HSV, which aligns with an earlier July 2024 report of an option around the same figure.
