Greek Super League 2026/27: Intel Report

Compiled 22 August 2026. Where I've derived a number myself rather than lifted it from a source, I've said so. Manager entries are omitted where I could not verify them this week rather than guessed.

1. League shape, and why this is the most model-hostile format in Europe

91st season of the Greek top flight, 68th since the 1st National Division was founded in 1959. Sponsor name: Stoiximan Super League.
Fourteen clubs. The smallest top flight in UEFA's top 12 leagues.
Phase 1: 26-match regular season (each club plays every other twice).
Phase 2, the critical part: the league splits three ways and every club carries forward HALF the points earned in phase one.
Championship playoff: top four, 6 matches each, decides the title and European places.
Europe playoff: 5th to 8th. In 2025/26 this became irrelevant because the Cup winner (OFI) finished outside the top four, so the Conference League place went to 4th instead. It only activates when the Cup winner finishes top four.
Relegation playout: 9th to 14th, 10 matches each, bottom two relegated to Super League 2.
Season opened 22 August 2026, ends May 2027.
Two Super League 2 clubs are promoted (the winners of the north and south groups).

The points-halving mechanic is the single most important thing to encode

Halving compresses everything. In 2025/26, AEL finished the regular season 12th on 23 points, six clear of Asteras Tripolis on 17. Halved, that became 11.5 versus 8.5, a three-point gap. AEL were relegated and Asteras survived. A cushion built over 26 games evaporated in one afternoon of arithmetic.

Model implications:

Any simulation must model phase one and phase two as separate competitions with a deterministic transformation between them. A flat 34-round simulation will be wrong.
Rounding matters. Odd point totals halve to .5, which changes tie-break behaviour.
Effective variance rises sharply after the split, because the same number of games now moves a compressed table. Late-season upset probability is structurally higher here than in a conventional league.
Cross-group fixtures stop existing after the split. A top-four club never plays a bottom-six club again, so head-to-head strength estimates go stale in the second half of the season.

A structural vote worth tracking

On 27 May 2026 the clubs voted on a proposal to scrap the playoff format, expand to 16 teams and play a straight 30-match season. The vote finished 7 in favour, 7 against, 1 abstention (Olympiacos) and therefore failed. Kifisia are expected to bring a version of it back for 2027/28. If it passes, everything in section 1 changes.

2. Baseline: 2025/26

Champions: AEK Athens, their 14th Greek title and third of the Super League era, sealed on 10 May 2026 with a 2-1 win over Panathinaikos.
Final top four: AEK, Olympiacos, PAOK, Panathinaikos.
Greek Cup winners: OFI, which is the single biggest story of the season and sends a Cretan club into the Europa League playoff round.
Relegated: AEL, Panserraikos.
Promoted from Super League 2: Iraklis (north group champions, back after nine years) and Kalamata (south group champions, back after twenty-five years).

2025/26 league-level numbers

Metric	Value
Matches	236
Goals	606, 2.57 per match
Top scorer	Ayoub El Kaabi (Olympiacos) 18
Longest unbeaten	AEK Athens 24
Longest winning run	Olympiacos 7
Longest winless	AEL 15
Longest losing run	Panserraikos 10
Highest attendance	32,954 (Olympiacos 0-1 Panathinaikos, 8 February 2026)
Lowest attendance	134 (Volos 0-3 Atromitos, 19 January 2026)
Total attendance	1,753,400
Average attendance	7,690

The 134 figure is not a typo and it is the most important number in this report for anyone modelling home advantage. The attendance range in this league runs from 134 to 32,954, a factor of roughly 246. For comparison, the Championship's range is about 5x and Serie B's about 20x. A league-wide home-advantage constant is indefensible here. Volos, Panetolikos, Kifisia and Levadiakos play in near-empty grounds while the Athens and Thessaloniki clubs play in genuinely hostile ones.

European allocation from 2025/26

Champions League: AEK Athens (playoff round), Olympiacos (third qualifying round, league path). Greece has two Champions League entrants for 2026/27.
Europa League: OFI (as Cup winners, playoff round), PAOK (second qualifying round).
Conference League: Panathinaikos (second qualifying round).

Model note: with five of fourteen clubs in Europe, European fixture congestion affects 36% of the division. That is a much higher proportion than in any of the other leagues covered and should carry a meaningful rotation/fatigue term for the big four plus OFI.

3. The market's opening view

Greek outright markets are thin. What is available:

AEK Athens, Olympiacos, PAOK and Panathinaikos are the only realistic title candidates. Three different champions in the last four seasons, so the league is unusually open by its own standards but still a closed shop relative to the other eleven clubs.
Olympiacos are the most decorated club in Greece with 48 titles, ahead of Panathinaikos on 20 and AEK on 14.
Relegation candidates flagged by previews: Iraklis and Kalamata (promoted clubs almost always land in the playout in year one), plus Asteras Tripolis, Panetolikos and Kifisia.
The Super League 2 outright market doubles as a relegation read: Panserraikos 3.25 to bounce straight back, Panionios and Niki Volos 4.50, Marko and AEL 1964 6.00.

Opening fixtures (22-23 August): AEK Athens v Iraklis, Kalamata v Aris, Olympiacos v Atromitos, with the rest on 23 August.

4. Club-by-club

AEK Athens

City: Athens (Nea Filadelfeia). Ground: OPAP Arena (Agia Sophia). 2025/26: Champions. Defending champions and the club with the most durable form line of the season: a 24-game unbeaten run. Their new stadium, opened in 2022, transformed their revenue and home environment after decades at the Olympic Stadium.

Expectation: title defence, Champions League playoff round.

Lore: founded 1924 by refugees from Constantinople after the population exchange, which is why the double-headed eagle and the Agia Sophia stadium name carry the weight they do.

Olympiacos

City: Piraeus. Ground: Karaiskakis Stadium (~32,000). 2025/26: 2nd.

48 Greek titles, more than double anyone else, and Conference League winners in 2024. Ayoub El Kaabi was the division's top scorer with 18. They lost 0-1 at home to Panathinaikos in front of 32,954 in February, the season's biggest crowd.

Expectation: title favourites in most quarters. Champions League third qualifying round.

Note: Olympiacos abstained on the May 2026 structural vote, which was decisive in it failing. Read that as the biggest club preferring the current format.

PAOK

City: Thessaloniki. Ground: Toumba (28,701). 2025/26: 3rd. Won 5-0 at Panserraikos in November. One of only three clubs (with Olympiacos and Panathinaikos) never to have been relegated.

Expectation: top four, Europa League second qualifying round.

Lore: Toumba is routinely rated among the most intimidating grounds in Europe and PAOK's rivalry with Olympiacos has repeatedly spilled into governance disputes.

Panathinaikos

City: Athens. Ground: OAKA / Leoforos. 2025/26: 4th. 20 titles and the only Greek club to have reached a European Cup final (1971). Won at Olympiacos in February.

Expectation: top four, Conference League second qualifying round. Underachieved relative to budget last season.

OFI

City: Heraklion, Crete. Ground: Theodoros Vardinogiannis. 2025/26: Greek Cup winners. The story of last season. A Cretan club winning the Cup and taking a Europa League playoff place is a genuine break in the Athens-Thessaloniki duopoly.

Expectation: European football will stretch a small squad. Watch for the fixture-congestion drag.

Model note: OFI is the club where a European-participation fatigue term will matter most, because unlike the big four they do not have the depth to absorb it.

Aris

City: Thessaloniki. Ground: Kleanthis Vikelidis (22,800). 2025/26: mid-table. The second Thessaloniki club and a well-supported one, perennially the best of the rest without breaking into the top four.

Expectation: 5th to 8th.

Levadiakos

City: Livadeia, Boeotia. Ground: Levadia Municipal Stadium. Statistically the most entertaining team in the division last season: 6-0 v Panetolikos, 5-2 v Panserraikos, 5-2 v Volos.

Expectation: mid-table with high goal variance.

Model note: three of the division's highest-scoring games involved Levadiakos. Worth a per-club goals-variance term.

Volos

City: Volos, Thessaly. Ground: Panthessaliko (22,700 capacity).

Recorded the lowest attendance in the division and possibly in any European top flight last season: 134 against Atromitos in January. They also lost 2-5 at AEL and 2-5 at Levadiakos.

Expectation: playout.

Model note: a 22,700-capacity ground drawing 134 means the "home advantage" term for Volos should be close to zero or possibly negative. This is the extreme case in the dataset.

Atromitos

City: Peristeri, western Athens. Ground: Peristeri Stadium (~9,000). Won 6-0 at Panserraikos on the final day and 3-0 at Volos in front of 134 people. Consistently punch above their resources.

Expectation: mid-table.

Asteras Tripolis

City: Tripoli, Arcadia (Peloponnese). Ground: Theodoros Kolokotronis.

Survived the playout in 2025/26 despite finishing the regular season 12 points adrift in raw terms and six behind AEL, because halving compressed the gap to three and they overturned it. That is the single best worked example of the format's effect.

Expectation: playout again, flagged as a relegation candidate.

Panetolikos

City: Agrinio, Aetolia-Acarnania. Ground: Panetolikos Stadium (~7,000). Conceded 6-0 at Levadiakos and 0-5 at home to AEK. Among the weakest attacking and defensive profiles in the division.

Expectation: relegation candidate.

AE Kifisia

City: Kifisia, northern Athens. Ground: Zirineio (~2,500 capacity, one of the smallest in any European top flight). A recent arrival: won Super League 2 in 2022/23 and again in 2024/25. Notable off the pitch as the club driving the proposal to scrap the playoff format and expand the league, expected to return for 2027/28.

Expectation: relegation candidate.

Iraklis (promoted)

City: Thessaloniki. Ground: Kaftanzoglio.

Super League 2 north group champions with a 24-game unbeaten run. Back in the top flight after nine years away, last seen in 2016/17.

Expectation: relegation candidate, but a large historic fanbase and a proper stadium.

Lore: the third Thessaloniki club and one of the oldest sports clubs in Greece (1908). Their decline through the lower divisions and financial re-formation is a long saga.

Kalamata (promoted)

City: Kalamata, Messinia. Ground: Kalamata Municipal Stadium.

Super League 2 south group champions with an 11-game winning run. Back in the top flight after twenty-five years, last seen in 2000/01.

Expectation: relegation favourite alongside Iraklis.

5. Style and trends: what to feed the model

League-level priors

Metric	2025/26 value	Implication
Goals per match	2.57	In line with Serie B (2.56) and the EFL (2.54-2.61).
Draws	~28-30% (my estimate, not derived)	I do not have the split. Greek leagues historically run draw-heavy because of the concentration of one-sided fixtures alongside a compressed lower half. Derive this yourself from a clean table before using it.
Average attendance	7,690	Comparable to Serie B (9,450) but with a vastly wider spread.
Attendance range	134 to 32,954 (246x)	The single most extreme home-advantage spread of any league covered.
Clubs in Europe	5 of 14 (36%)	Highest proportion of any league covered. Rotation and congestion effects are material.

Structural features to encode

Two-phase season with a points halving at the split. Not optional. A flat-season simulation will misprice relegation and title probabilities.
Per-club home-advantage coefficients, not a league constant. The 246x attendance range makes this the clearest case in the dataset.
European fatigue term for AEK, Olympiacos, PAOK, Panathinaikos and OFI, with OFI weighted most heavily because of squad depth.
Post-split fixture-set change. After 26 rounds, top-four clubs only play each other and bottom-six clubs only play each other. Any rating that relies on a common opponent pool degrades from that point.
Promoted-club prior. Both previews and history say promoted Greek clubs land in the playout in year one. Iraklis and Kalamata should carry a strong negative prior.
Format change risk for 2027/28. The May 2026 vote failed 7-7-1. If it passes next time, the league goes to 16 teams, 30 matches, no playoffs. Do not hard-code the current structure into anything long-lived.

Clubs with distinct markers

Levadiakos: highest goal variance (6-0, two 5-2s).
Volos: effectively no crowd; extreme low end of home advantage.
Asteras Tripolis: the worked example of the halving mechanic.
AEK: 24-game unbeaten run, the most stable form line in the division.

6. Caveats

I did not verify head coaches for any of the fourteen clubs this week and have deliberately omitted them rather than guess. Pull them before use.
The draw share is an estimate, not a derivation. I did not have a clean 2025/26 table with wins/draws/losses.
Super League 2 for 2026/27 is being reduced to 16 clubs in a single group, and as of the last confirmed source the promotion and relegation quotas from it had not been finalised. If you model the second tier, check that first.
Greek clubs change coaches extremely frequently and mid-season managerial churn is higher here than in the English or Italian leagues covered.
Stadium capacities for the smaller clubs are from background knowledge and are approximate.
