Born on 15 February 2000 in Tychy, a city in southern Poland, Kiwior has built an impressive career that has taken him from the youth pitches of Tychy all the way to the English Premier League with Arsenal and now to FC Porto in Portugal.

He is widely regarded as one of Poland's most technically gifted defenders of his generation, known for his composure on the ball, reading of the game, and versatility across the backline. In 2026, Kiwior is very much in the conversation as one of European football's most sought-after defensive talents.

Jakub Kiwior Net Worth and Salary in 2026

Based on available data from his professional contracts, endorsements, and career earnings, Icon Polls estimates Jakub Kiwior's net worth in 2026 to be somewhere between $25 million and $33 million.

His salary at FC Porto is reported to be around EUR 3 million per year, which works out to roughly EUR 57,000 per week.

Jakub Kiwior at Spezia - Where It All Started

For many football fans, Spezia is where they first heard the name Jakub Kiwior. He joined the Italian Serie A club on a four-year deal in August 2021, and his performances there caught the attention of clubs across Europe.

In his time at Spezia, Kiwior made 39 appearances and established himself as a composed, ball-playing defender who could operate in a back three or back four. His ability to play from the back, win aerial duels, and track runners made him a standout performer in Serie A. He was deployed in various roles there too, sometimes as a defensive midfielder under manager Thiago Motta, which showed just how technically versatile he was.

It was those Spezia performances that convinced Arsenal to splash around EUR 19.5 million in January 2023 to bring him to the Premier League. Given that his current market value stands at around EUR 27 million, Arsenal definitely got a good deal at the time.

Jakub Kiwior Parents

Jakub Kiwior was raised in Tychy, Poland, by his parents Agnieszka Kiwior and Piotr Kiwior. His father Piotr is a construction engineer who reportedly suspended his own career and relocated to Belgium when a teenage Jakub earned an opportunity at the RSC Anderlecht academy. That kind of sacrifice speaks volumes about the family's commitment to supporting Jakub's dream.

His mother Agnieszka held down the fort back home in Poland, caring for Jakub's younger brother Kamil while Piotr travelled abroad with Jakub. By most accounts, they are a tight-knit family with strong values. Jakub has spoken fondly about his upbringing and the role his parents played in shaping him as both a footballer and a person.

Piotr is said to have been instrumental in getting Jakub into football at a young age, recognising his talent from around age four. The family's patience and sacrifice clearly paid off.

Jakub Kiwior Religion

Jakub Kiwior has not made any public statements specifically about his religious beliefs. However, given that he was born and raised in Tychy, Poland, a country where Roman Catholicism is deeply embedded in the culture and where the vast majority of the population identifies as Catholic, it is widely understood that he was raised in the Christian faith.

His first youth club was even named PUKKS Chrzciciel Tychy, a name with Christian significance. Nothing in his public profile contradicts this background, and like many Polish athletes, he tends to keep his personal faith private.

Jakub Kiwior Nationality and International Career

Jakub Kiwior is Polish. He was born in Tychy, Poland, and represents the Polish national team at international level. He has been capped at every youth level from U16 upward and made his senior debut for Poland on 11 June 2022.

He has gone on to become an important player for the national team, starting every match for Poland at both the 2022 FIFA World Cup in Qatar and UEFA Euro 2024 in Germany. He even scored his first international goal in a memorable 1-0 friendly win against Germany in June 2023.

In 2026, he remains part of Poland's national team setup as they look toward qualification for future tournaments. His international profile adds to his overall market appeal and remains a key part of his identity as a player.

Jakub Kiwior Transfer Values in 2026

Kiwior's current estimated transfer value sits between EUR 22.7 million and EUR 27.7 million, with the mid-point estimate being around EUR 25 million. He is currently on loan at FC Porto from Arsenal, with a mandatory obligation to buy clause in his loan deal that Porto are expected to trigger before 31 May 2026, making the permanent fee approximately EUR 17 million plus potential bonuses of up to EUR 5 million.

Arsenal originally paid around EUR 19.5 million to sign him from Spezia in January 2023. Despite him never being a guaranteed starter at the Emirates, they were able to build in a deal that allows them to recoup their investment. The move was seen as a sensible piece of business for all parties.

Looking further ahead, reports suggest Juventus are interested in signing Kiwior from Porto for around EUR 30 million, which would represent a significant profit for Porto should they choose to sell. Based on his performances in Portugal this season, helping Porto keep 12 clean sheets in the league, it seems likely his value will continue to rise.

According to Icon Polls research, Kiwior's transfer fee could realistically command between EUR 25 million and EUR 35 million by the end of 2026 depending on his continued form and whether Juventus or any other major club makes a firm bid.
