TransferFeed valuation based on market analysis.
According to a June 2026 report, FC Köln exercised a purchase option to sign the player permanently for a fee of €5.5 million. An earlier report from April 2026 indicated the club's intention to make the loan permanent as part of a package for five players, with the total cost for all of them estimated at around €20 million.
Our valuation for Jakub Kaminski is driven directly by the recent and specific report that FC Köln has exercised their purchase option for a fee of €5.5 million. This figure represents a recently agreed-upon market value between two clubs, providing a strong and clear basis for our estimate.
