Charalampos Kostoulas

In February 2026, the player's market value was reportedly €25 million according to Transfermarkt. This followed his major transfer in July 2025 from Olympiakos to Brighton, which was officially completed for a reported base fee of €35 million. Various reports at the time cited different figures for the deal, ranging from €35 million to as high as €50 million, with a common figure being a €35 million base fee plus add-ons that could take the total to €41 million. Prior to the move, in May-June 2025, reports suggested Brighton's initial offers were over €30 million, while Olympiacos's valuation was reportedly over €50 million. Earlier valuations were lower, with reports in December 2024 and March 2025 suggesting Olympiacos was open to offers around €20-€30 million.

Our valuation is driven by the very recent, high-profile transfer of Charalampos Kostoulas to Brighton in July 2025. The reported fee had a base of €35 million, with potential add-ons taking the total package to over €40 million. His subsequent regular involvement in the Premier League at a young age solidifies this high valuation, despite a more conservative recent market value estimate from Transfermarkt.
