Will the Iranian soccer team be able to play all of their scheduled matches in the 2026 FIFA World Cup?

TL;DR

I forecast Yes at 98%. Iran has already completed all three Group G matches, so a No now requires Iran to advance and then fail to play a future knockout match. The remaining tail is real because of U.S.-Iran conflict and travel controls, but the same systems have already let Iran enter the United States and play three times.

Context

As of 07:14 UTC on June 27, Iran had completed its group schedule: 2-2 vs New Zealand on June 16, 0-0 vs Belgium on June 21, and 1-1 vs Egypt on June 27, all in the official World Cup first stage data (FIFA schedule/results). Iran finished third in Group G on 3 points, 0 goal difference, and 3 goals scored; Belgium and Egypt finished ahead on 5 points, while Iran was waiting on other third-place results (Iran International, Jun. 27). The 2026 format sends the top two teams in each of 12 groups plus the eight best third-placed teams to the Round of 32 (FIFA format explainer, updated Jun. 15).

The original participation risk has mostly resolved. U.S. officials said on June 5 that Iran’s players and necessary staff had visas, while visa frictions pushed Iran’s base from Tucson to Tijuana (AP, Jun. 5). After the first match, the U.S. required Iran to leave the country shortly after games, but a player visa problem was fixed and the State Department said it worked to ensure the player could participate in every game (AP, Jun. 16). Before the Seattle match, DHS eased the rule and allowed Iran to enter two days before kickoff, while still requiring departure after the match (AP, Jun. 23).

Evidence

The historical base rate is one-sided. The main post-qualification withdrawal analogues are old and pre-tournament: Austria in 1938 and India, Scotland, Turkey, and France in 1950; Le Monde’s March 2026 review said that since the 1950 World Cup no team had given up its place in the tournament (Le Monde, Mar. 5). My reference class is stricter: 432 team-tournament entries from 1954 through 2022, with no case I found of a team that started the finals and then failed to complete a later scheduled finals match (FIFA World Cup historical competition page). World Cup finals match abandonment is also an extreme tail; a June 2026 review described France-Iraq’s weather delay as coming close to becoming a first World Cup abandonment, not as one that had happened (FourFourTwo, Jun. 25).

The live sporting branch matters because elimination is already a Yes. FIFA data showed 66 of 72 group-stage matches complete at the forecast time, with Groups J, K, and L still unfinished (FIFA schedule/results). Iran is eliminated only if all three remaining group branches produce a third-placed team above Iran’s 3 points, 0 goal difference, and 3 goals scored. I model the branches this way, using FIFA tables for the state and World Football Elo for match probabilities (World Football Elo Ratings):

That gives a 9% chance Iran is eliminated as a third-placed team and a 91% chance it reaches the Round of 32: P(eliminated) = 0.30 × 0.34 × 0.91 = 0.093. I raise the Algeria-Austria draw probability above the raw Elo draw rate of 24% because a draw is valuable to both sides; I leave the DR Congo branch at the raw Elo win rate of 34%; and I compute the Group L pass rate from the raw Elo probabilities that Ghana beat Croatia at 9.3% and Panama beat England at 7.0% (World Football Elo Ratings).

Conditional on Iran advancing, I put the chance of failing to complete all future scheduled matches at 2.5%. This is far above the modern World Cup finals base rate, because the U.S. struck Iranian missile, drone, and radar sites on June 26 after a cargo-ship drone attack that President Trump called a ceasefire violation (AP, Jun. 26). It is still low because the same week also brought a 60-day diplomatic process and stated mechanisms to keep the Strait of Hormuz open, while FIFA and the U.S. have already solved practical player-entry problems rather than allow a forfeit (AP, Jun. 22; AP, Jun. 16). FIFA’s 2026 regulations also make a late withdrawal costly, with legal commentary citing a minimum CHF 500,000 fine for withdrawal less than 30 days before the final competition and further disciplinary consequences for non-competing (CMS legal summary, Jun. 2026).

The final model is simple: P(Yes) = 1 - P(advance) × P(non-completion if Iran advances). With P(advance) = 90.7% and P(non-completion if Iran advances) = 2.5%, P(Yes) is about 98%.

What's non-obvious

The common May narrative treated Iran’s participation as an unresolved geopolitical problem. By June 27, the strongest evidence is revealed behavior: Iran entered the United States for Los Angeles and Seattle matches, accepted a Mexico base, handled same-day or near-same-day travel rules, and still played the three matches that mattered for this question (AP, Jun. 5; AP, Jun. 23; FIFA schedule/results). That is more informative than earlier boycott language.

The odd part is that Iran advancing slightly lowers the Yes probability. If Iran is eliminated as a third-placed team, it has no more scheduled World Cup matches and the resolution is effectively Yes. If Iran advances, it earns at least one new match and reopens a small travel, political, security, and disciplinary tail.

Limitations

Iran’s Round of 32 status was not official at 07:14 UTC because the final matches in Groups J, K, and L had not been played (FIFA schedule/results). The 91% advance estimate is therefore a model result, not a confirmed FIFA qualification.

The conditional 2.5% non-completion risk is the least data-rich part of the forecast. There is no clean historical sample of a team that had already started a World Cup while its government was in direct conflict with a host government. I could verify public match completion, visa actions, official fixtures, and news of conflict and talks; I could not verify private DHS, FIFA, Canadian, Mexican, or Iranian contingency decisions.
