How VAR Works at the World Cup 2026

VAR is used at every match of the 2026 World Cup. It reviews the same four categories as in club football — goals, penalties, direct red cards, and mistaken identity — and applies the clear-and-obvious-error threshold. The main difference is technology: the World Cup uses semi-automated offside and high-frame-rate camera coverage, making reviews faster and more accurate.

What does VAR review at the World Cup?

The VAR protocol reviews exactly four categories:

1. Goals — was the goal scored legally? (offside, foul in the build-up, ball out of play)
2. Penalty decisions — penalty given when it shouldn't be, or penalty missed when it should have been awarded.
3. Direct red cards — straight red, not second yellow.
4. Mistaken identity — referee booked or sent off the wrong player.

Anything outside these categories — yellow cards, throw-ins, corners, free kicks — is not reviewable. See /rules/var-reviewable-incidents for full detail.

What is semi-automated offside (SAOT)?

Semi-automated offside technology uses:

• 12 tracking cameras mounted under the stadium roof
• 29 data points captured on every player at 50 frames per second
• A motion sensor in the match ball that registers exactly when a pass is played

The system computes the offside line and the attacker's position automatically and alerts the VAR within a few seconds. The VAR confirms the data, and the broadcast generates a 3D-rendered offside graphic. Average offside review time dropped from around 70 seconds at Russia 2018 to under 25 seconds at Qatar 2022, and 2026 is faster still.

How does the clear-and-obvious-error threshold work?

VAR doesn't second-guess every call. It only intervenes for clear and obvious errors in the four reviewable categories. If the on-field decision is defensible — even if VAR would have called it differently — VAR doesn't get involved. The high bar exists to keep matches flowing and respect the referee's authority.

What is an on-field review?

For subjective calls (penalty/no penalty, red card/no red card), the VAR recommends a review. The referee jogs to a screen at the side of the pitch, watches the replay, and decides. This is called the on-field review (OFR). For factual calls — offside, ball out of play — VAR can communicate the decision directly without sending the referee to the screen.

If a review overturns the original decision, see /rules/why-did-var-not-overturn-it for why some plays don't get changed even when fans expect them to.

What's new at the 2026 World Cup?

• Connected Ball Technology — the match ball includes an inertial measurement unit that broadcasts position data 500 times per second. Combined with limb tracking, it lets SAOT detect the exact frame the ball is played.
• Stadium-wide tracking — every venue has the full SAOT camera array installed, so reviews are consistent from group stage to final.
• Faster offside graphics — 3D-rendered visuals for broadcast within ~25 seconds of a goal.
