Football - Spain King's Cup - 2025/2026 season

The cup that kept being decided in one night, then two, then one again

The Spanish King's Cup in the 2025/2026 season once again confirmed why this is a tournament in which a name does not mean safety, and an away match in a smaller town often looks like an ambush. The road to the final began as early as late September 2025, with the preliminary round for 20 clubs from the territorial level, played in two matches on 27 September and 4 October. After that came the first real sieve: 56 first-round fixtures from 28 to 30 October, then the second round from 2 to 4 December. The round of 32 was played between 16 and 18 December and on 6 January, the round of 16 on 13, 14 and 15 January, the quarter-finals between 3 and 5 February, while the semi-finals remained the only stage played over two legs, with the first matches on 11 and 12 February and the return legs on 3 and 4 March. The final is scheduled for 18 April 2026 at 21:00 at La Cartuja in Seville. That competition structure still has the old charm of the Spanish cup: until the quarter-finals, life is generally decided by a single match, by one goalkeeper's mistake, one set piece, one night in which a second-division or third-division club plays beyond its own limits. Only in the semi-finals does the competition allow a second chance. That is why, in the King's Cup, there is less talk about control and more about survival.

What the format looks like, specifically

This season the schedule was very clear and very cruel in the Spanish way:

• Preliminary round: 20 clubs, 10 pairings, two matches.
• First round: 112 clubs, 56 one-off matches.
• Second round: 56 clubs, 28 one-off matches.
• Round of 32: 32 clubs, one match.
• Round of 16: 16 clubs, one match.
• Quarter-finals: 8 clubs, one match.
• Semi-finals: 4 clubs, two matches, with no away-goals rule.
• Final: 1 match at a neutral venue.

The four clubs that played in the Spanish Super Cup were exempt from the first round: Barcelona, Real Madrid, Atlético de Madrid and Athletic Club. That is no small matter, because in this cup an extra round often also means an extra mine. The others had to make their way through the October and December traffic, in a rhythm in which the cup easily turns into a war of attrition.

Who was in it all, and who stayed until the end

When the round of 16 arrived in early January, the list of survivors already looked serious. At that stage there were RC Deportivo, Cultural y Deportiva Leonesa, Racing Santander, Albacete Balompié, Burgos CF, Elche CF, Real Sociedad, Valencia CF, Barcelona, Atlético de Madrid, Osasuna, Deportivo Alavés, Real Madrid, Real Betis, while the last place awaited the winner of the tie Granada - Rayo Vallecano. That was already the phase in which the tournament tightens: second-division clubs are still breathing, but the pressure from top-flight teams becomes heavier and heavier. The clubs that reached the quarter-finals were Albacete, Deportivo Alavés, Real Sociedad, Real Betis, Valencia, Athletic Club, Atlético de Madrid and Barcelona. That was where the true nature of the cup became visible. Albacete were the story everyone wants, but rarely gets; Athletic snatched qualification at Mestalla with a goal by Iñaki Williams in the 96th minute; Real Sociedad came through a Basque clash with Alavés by a score of 3:2; Atlético left Betis with five goals and very little air in Seville. In the end, the semi-finals consisted of four clubs bearing a clear stamp of history: Barcelona, Atlético de Madrid, Athletic Club and Real Sociedad. It was not a final stretch full of exotic surprises, but a final stretch full of clubs that know how to play for the cup, how to cope with pressure and how a two-legged tie can be won without much romance.

A semi-final that smelled of the eighties

The draw paired two ties that had both weight and story. One semi-final was Athletic Club - Real Sociedad, therefore a Basque derby for a place in the final. The other was Atlético de Madrid - Barcelona, a clash between teams that had already produced madness from a two-legged tie in the cup a season earlier. The first matches were played on 11 and 12 February 2026 at San Mamés in Bilbao and at the Metropolitano in Madrid. The return legs were on 3 and 4 March at Camp Nou in Barcelona and at Anoeta in San Sebastián. In theory, that was the schedule. In practice, they were four nights in which the King's Cup showed how equally it loves discipline and delirium. Atlético tore Barcelona apart 4:0 in Madrid. That was not just a victory, but a blow that pushed the semi-final almost over the edge. The return leg at Camp Nou ended with a 3:0 win for Barcelona, but Madrid's 4:0 was enough for Diego Simeone's team to return to the final for the first time in 13 years. On aggregate: 4:3 for Atlético. That is this cup: one club spends three weeks repairing the damage it took in a single evening. On the other side of the draw there were no fireworks, but a knife to the bone. Athletic and Real Sociedad played two matches that looked as if someone had cut them with a scalpel. Real Sociedad went through with 1:0 twice, an aggregate of 2:0, and secured their second final in the last seven years. The Basque derby was not lavish on the scoreboard, but it was dense, hard and full of the kind of tension that makes the crowd breathe in short bursts.

The 2026 final: Seville, La Cartuja, Atlético against Real Sociedad

So the 2025/2026 cup got a final that is not the daily routine of Spanish football: Atlético de Madrid - Real Sociedad. It is also special that those clubs are meeting again in a cup final almost like an echo of the 1986/1987 season. Even before the final, the RFEF announced that the match would be played on 18 April 2026, at 21:00, at La Cartuja in Seville, the stadium that will host the final for the seventh year in a row. For the fans, one figure is also important because it shows well how big the final has become: the RFEF announced that more than 52,000 tickets, that is around 80% of the stadium's capacity, would be allocated to the finalists. That is a figure that also reveals the dimension of the stage itself. After the expansion, La Cartuja now holds around 70,000 spectators, so the final is no longer only a big match, but also a logistical operation on the level of European finals.

The stadiums that carried the final phase

The final phase of this edition was not played in anonymous grounds, but in stadiums that each carry their own geography and their own football temperament.

• Riyadh Air Metropolitano, Madrid – Atlético's home, capacity around 70,692 spectators. It was there that Atlético built the foundation of the final against Barcelona with that 4:0 that changed the whole elimination.
• San Mamés, Bilbao – Athletic's home, capacity 53,331. In Bilbao's "Cathedral", every cup tie sounds as though the walls are pushing the team towards the goal.
• Anoeta / Reale Arena, San Sebastián – Real Sociedad's stadium, capacity 40,000. It was there that the final place was confirmed, in a return leg that had more tension than space.
• La Cartuja, Seville – host of the final, capacity 70,000 after the latest expansion. It is today one of the biggest stadiums in Spain and the permanent stage of the cup final.

It is interesting how those four cities almost drew a map of Spanish football: Madrid as the centre of pressure and resources, Bilbao as a place of identity, San Sebastián as a club that knows how to play elegantly and painfully, and Seville as the neutral closing scene on which the cup turns into a national spectacle.

The defending champion and the latest winners

This season began with Barcelona as defending champions, after they beat Real Madrid 3:2 after extra time in the final on 26 April 2025 in front of 55,579 spectators at La Cartuja. The year before, on 6 April 2024, Athletic Club lifted the trophy in the same stadium against Mallorca, after a 1:1 draw and a penalty shoot-out, in front of 57,619 spectators. Those two attendance figures say a lot about continuity. In recent seasons, the King's Cup final is no longer just a national sporting event, but also a mirror of the popularity of the clubs that reach it. Barcelona and Real Madrid brought global weight, Athletic and Mallorca the emotional charge of one long Basque hunger for a trophy and one island story. Atlético and Real Sociedad in the 2026 final bring something else: a clash of very different football temperaments without needing the royal crests of Madrid or Barcelona for the event to be big.

History that presses on every new season

The King's Cup has been played since 1903, and that fact is not an ornament but the burden and privilege of every edition. There are not many European cups in which you can move so easily from the present into a black-and-white archive. When Athletic step out for a cup match, they carry an entire Basque century with them. When Barcelona play in the cup, they carry the club with the most titles. When Real Sociedad come close to the final, both 2020 and that old final stretch from the eighties come alive again. The cup is not just a tournament; it is an archive that is constantly opening. By number of trophies, the most successful club is Barcelona with 32 titles, followed by Athletic Club with 24, while among the historical record-holders of the competition, Piru Gaínza with 99 appearances and the legendary Telmo Zarra with 81 goals stand out in particular. Those figures sound as if they come from another football planet, but that is precisely why the King's Cup is never only about the current season. Every new goalscorer enters a competition in which the older records are almost mythical. For Atlético, the 2026 final is a chase for an eleventh cup title and a chance to end a wait that has lasted since 2013. For Real Sociedad, it is a chance for a third title and confirmation that the trophy from 2020 was not an isolated episode, but part of a serious club era.

Numbers that say more than clichés

If this season is viewed through a few clean numbers, the picture is very clear:

• 20 clubs opened the tournament in the preliminary round.
• 56 first-round matches were stretched across three October days.
• 28 fixtures made up the second round at the beginning of December.
• 32 clubs reached the round of 32.
• 16 remained in January.
• 8 played in the quarter-finals.
• 4 reached the semi-finals: Barcelona, Atlético, Athletic and Real Sociedad.
• 2 survived: Atlético de Madrid and Real Sociedad.

Alongside that, the 2025 final attracted 55,579 spectators, the 2024 final 57,619, and for the 2026 final more than 52,000 tickets have been allocated to the finalists. That is a very clean story about a cup that still fills the stadium regardless of whether Barcelona and Real Madrid are in the final stretch or some different pair.

Stories that remain: Athletic's 96th, Atlético against time, Real Sociedad against its own shadow

Every cup has one match that defines it, but this edition had several. Athletic went through at Mestalla with a goal in the 96th minute and reminded everyone that the cup is often decided when all eyes are already turning towards extra time. Atlético scored four against Barcelona in one evening, then spent ninety minutes in the return leg under pressure to defend everything they had earned. Real Sociedad, by contrast, reached the final in almost the opposite style: without fanfare, with two 1:0 victories against their biggest regional rival. One path was an explosion, the other a cutting of the nerve. That may be the best description of the 2025/2026 King's Cup. It was not a tournament of one colour. It had Madrid brutality, Basque tension, a Seville backdrop and Barcelona's fall as defending champions before the very final stretch. That is why the title match in April 2026 is more than a final. It is a meeting of two completely different trajectories: Atlético arrived through the blow of 4:0 and survival in the return leg, Real Sociedad through the discipline of two 1:0 wins. One finalist shouted, the other whispered. Both arrived in Seville.
