How this was compiled: Checked on 13 September 2026, after the final ended. Scores from both final matches and the third-place match were recounted by us from the official Lichess broadcast PGN and checked against the FIDE and Chess.com reports, which are also the source for the final's format, the individual awards and Nepomniachtchi's quote. Day 8 results come from Chess.com. The Carlsen–Nepomniachtchi comparison was built by us from each player's twelve games on the icon board: ten from the group stage and two from the final. Evaluations from the decisive game were measured by us with a local Stockfish 19 at depth 28 (27 for one alternative); at depth 22 the position after 31.Kf1 swung between -1.5 and -4.1 from one measurement to the next, so the published numbers are those of the deeper run.

The essentials in a few lines

• Ganges Grandmasters beat Alpine APL Pipers 7-5 in the Global Chess League 2026 final on 13 September in Bengaluru: 3-3 in the first match and 4-2 in the second, with every win worth 1 point regardless of colour.
• In the second match Nepomniachtchi beat Carlsen with Black in an Open Catalan, Tsolakidou beat Humpy Koneru and the other four boards were drawn. Tsolakidou was named the league's best player, according to FIDE.
• Measured by us with Stockfish 19 at depth 28: before move 28 Carlsen had +3.29. 28.Qxb5 took the position to 0.00, 30.Kxf2 to -1.12 (30.Kf1 kept 0.00) and 31.Kf1 to -6.20 (31.Kg1 left -1.52). Carlsen played 28.Qxb5 with more than ten minutes on his clock.
• Across twelve icon-board games, Carlsen opened 1.e4 three times and 1.d4, 1.Nf3 and 1.g3 once each, never 1.c4. Nepomniachtchi opened 1.e4 five times and 1.c4 once. Against 1.e4, both always answered 1...c5.
• In their four meetings this season there were three draws and one win, Nepomniachtchi's in the final. Carlsen scored 7 points from 12 games; Nepomniachtchi, 7.5.

The final score

The final did not use the group-stage scoring, in which a win with Black is worth more. In both matches each win was worth 1 point and each draw half a point, and the title went to the higher total across the two. The time control was 20 minutes per player, with a 2-second increment from move 41.

Alpine APL Pipers reached the final as defending champions without winning on the last group day: they lost 11-6 to Triveni Continental Kings, in the match where Alireza Firouzja handed Carlsen his first loss of the season. Ganges lost that day too, 9-7 to PBG Alaskan Knights, and both teams went through on what they had already banked.

In the third-place match FYERS American Gambits beat CheQ Mumba Masters 7.5-4.5 on aggregate, with Nihal Sarin named player of the match. Tsolakidou, whose win decided the title, was named the league's best player, according to FIDE.

Carlsen winning with White: how the Catalan turned

The game began 1.Nf3 d5 2.g3 Nf6 3.Bg2 e6 4.O-O Be7 5.c4 O-O 6.d4 dxc4, an Open Catalan by the knight-first move order. Carlsen regained the pawn with 7.Qa4 a6 8.Qxc4 b5 9.Qc2 Bb7 10.Bd2 and, after 15.Ne5 Nxe5 16.dxe5, planted a rook on d6 on move 19.

The first error was Nepomniachtchi's. With 20...c4 the position measured 0.00; 20...Qb7 left +0.66, and Carlsen followed with 21.Qa5, 22.Ra7 and 24.Rb7 until a pair of rooks came off on b8. Before move 28, with the other rook back on d6, the engine measured +3.29 and pointed to 28.Be3.

28.Qxb5 is the kind of move that explains itself: a free pawn and an active queen. What it cost was control of the dark squares. 28...c4 opened the b6 bishop's diagonal to f2, and after 29.Qd7 Bxf2+ an evaluation of more than three pawns was down to zero. The clock doesn't explain it: Carlsen played 28.Qxb5 with 10 minutes 21 seconds left, and Nepomniachtchi had practically the same.

A sacrifice that didn't win, and worked

After the game, according to FIDE, Nepomniachtchi put it this way: "I have to admit that I got insanely unlucky as I prepared for this game with Black, and I had not thought of the line, and I was in trouble. But then I had just one idea left and I was hoping that he blunders and he did, and I got lucky."

The quote is more accurate than it sounds, and the engine confirms both halves. Nepomniachtchi's position was lost before move 28, and the sacrifice did not save it by force. What 29...Bxf2+ did was swap a passive position for one in which White had to find the exact king move twice in a row. Carlsen found neither.

On move 31 Carlsen spent almost three minutes and played 31.Kf1 with 5 minutes 47 seconds left, against Nepomniachtchi's 10 minutes. After 31...Qc5 the engine finds no defence: 32.Rd2 and 32.Rd4 both measure around -6.6. The game ended on move 39.

Carlsen and Nepomniachtchi across the season, side by side

This rivalry is often described as positional Carlsen, with 1.c4 and 1.d4, against tactical Nepomniachtchi. The season's PGNs do not support the first half. Carlsen opened no game with 1.c4 and only one with 1.d4, his loss to Firouzja; the player who opened 1.c4 was Nepomniachtchi, against Firouzja himself. Carlsen played 1.e4 more than any other first move, and the decisive game of the final reached the Catalan via 1.Nf3 and 2.g3.

Their four meetings this season have a symmetry the score doesn't show. In the first, in the group stage, Carlsen saved a lost position against Nepomniachtchi, as this coverage reported on 7 September. In the last, in the final, the roles were reversed: Nepomniachtchi was the one who was lost and took the point. The two in between were drawn.

With Black, the difference between them showed against queen's pawn and knight openings. Nepomniachtchi lost the only game in which he faced 1.d4, against Sindarov, and won the Catalan in the final; Carlsen faced 1.Nf3 once, against Firouzja, and drew.
