Jakub Kiwior’s permanent transfer to FC Porto has now been confirmed, with the Arsenal loanee’s new club revealing that they’ve activated his purchase option.
FC Porto have confirmed that they’ve activated their option to buy Jakub Kiwior, signing him on a long-term contract to 2030.
Porto write that they’ve exercised their purchase option in Kiwior’s loan agreement, transferring 100% of the defender’s sporting registration rights to the Portuguese club.
The deal involves a fixed fee of €17m, plus another €5m in potential add-ons, and Arsenal also retain a fixed €2m sell-on clause (meaning that if Porto ever sell Kiwior, they’ll owe the Gunners an extra €2m, regardless of the sale price).
Arsenal also received a €2m loan fee from Porto last summer, so the deal therefore has a maximum value to Arsenal of €26m (£22.5m). The Gunners signed Kiwior for €20m (then £17.6m) in 2023.
For what it’s worth, Porto have included a €70m release clause in the player’s contract.
It’s normal to include release clauses in the contracts of players in Portugal, but they’re generally priced on the higher side to dissuade any potential buyers from skipping fee negotiations and just paying the clause.
There’s no real expectation that anyone will be paying €70m for Kiwior this summer, so the defender will presumably be preparing for the 2026/27 campaign with his new club.
Kiwior recently won the Liga Portugal with Porto, which is perhaps what prompted the club to start moving on their summer transfer business, including making the loanee’s move permanent.
The club have two further league games before beginning their summer holidays, but they’ll be in party mode having wrapped up the title early.
Kiwior made 68 appearances for Arsenal across two-and-a-half seasons, before spending the 2025/26 campaign playing 38 times for Porto (so far). He won the Community Shield during his time in north London.
