From 3D player avatars and smart ball sensors to Google Gemini powering Argentina's tactics and robot security dogs, the 2026 FIFA World Cup is the largest live deployment of AI in sports history. Here is every technology explained.

Hedgerows are climate assets hiding in plain sight. Google Research's vectorized Farmscapes dataset, built on an RSF ViT backbone and dual-layer LiDAR labeling, maps these fine-scale woody features at national scale—opening a new path to carbon accounting without sacrificing farmland.

Frigate NVR has revolutionized home and small business surveillance by bringing enterprise-grade AI object detection to local hardware. Built for Home Assistant with OpenCV and TensorFlow, it offers real-time monitoring without cloud dependencies.
The 2026 FIFA World Cup, spanning 16 host cities across the US, Canada, and Mexico over 104 matches, is the largest tournament in the competition's history. It is also the largest live deployment of artificial intelligence in the history of sport.
From the moment a player enters the stadium through a biometric gate, to the VAR room rendering a 3D offside animation at 500Hz, to Google Gemini briefing Argentina's coaching staff before kickoff — AI is embedded at every layer of the event.
Here is every technology, explained.
The official match ball — the Adidas Trionda — contains an inertial measurement unit (IMU) sensor running at 500Hz. That means it captures 500 readings per second on movement, spin, and the exact moment of contact with a player's boot.
This matters most for offside decisions. When a pass is played, the sensor identifies the precise millisecond the ball leaves the player's foot. That timestamp is synchronized with the player-tracking system, which locks every player's position at that exact moment — not half a second earlier or later as human eyes would judge.
The result: offside calls that are faster and more accurate than anything possible with conventional camera-based detection alone.
FIFA's Semi-Automated Offside Technology (SAOT) has been upgraded significantly for 2026. The centerpiece is 3D player avatars.
Every player in the tournament is digitally scanned to create a full 3D body model — a process that takes approximately one second per scan and captures precise body-part dimensions. When an offside decision goes to VAR, the system overlays these 3D models onto the real-time tracking data from the 12+ dedicated tracking cameras in each stadium.
This solves a longstanding problem with 2D offside lines: a player's arm, shoulder, or foot might be partially obstructed from any single camera angle. The 3D model fills in those gaps, using anatomical data to accurately reconstruct where the relevant body part actually was at the moment of the pass.
The call is then displayed as a fully rendered 3D animation — both in the stadium and on broadcast — replacing the flat blue-and-red lines that became notorious for confusing fans.
FIFA partnered with Lenovo to build Football AI Pro, a platform built on top of FIFA's proprietary Football Language model — a foundation model trained on hundreds of millions of football data points spanning decades of FIFA-organized competitions.
Football AI Pro outputs insights in multiple formats: text summaries, video clips, interactive graphs, and 3D tactical visualizations. It is the first time in World Cup history that all 48 participating teams have access to the same analytical platform, rather than wealthier federations having an edge purely from better data tooling.
Teams can use it before and after matches for:
Note: FIFA explicitly prohibits its use during live play — coaching staff can use it at halftime and post-match, not while the game is in progress.
For the first time across all 104 World Cup matches, referees are wearing body cameras.
The raw footage from a referee running at pace is unusable for broadcast — too shaky, too erratic. FIFA runs every frame through an AI stabilization model in real time, smoothing the motion so the footage is broadcast-ready. The result is a "Referee View" broadcast feed: a subjective, ground-level perspective of the match that has already become one of the most popular new broadcast innovations with fans.
This feed is available to rights-holding broadcasters and offers analysts a new data source — the exact field of view of the official when making a decision.
In March 2026, the Argentine Football Association announced Google as a main global sponsor, with Gemini branding appearing on training kits of the men's, women's, and youth squads.
The partnership goes beyond branding. The technical staff uses Gemini for:
Argentina's players and coaches use Gemini directly — not through a custom interface, but through the standard Gemini app — reflecting how far general-purpose AI tools have matured for professional sports applications.
Beyond Argentina's camp, Google rolled out a wave of Gemini-powered fan features across its products for the tournament:
| Feature | Where |
|---|---|
| Live scores pinned to lock screen | Android / Pixel |
| AI match briefings (pre-match summary) | Gemini app |
| Tactical diagrams on demand | Gemini app |
| Team jersey photo templates | Google Photos / Gemini |
| Real-time stadium navigation | Google Maps / Waze |
| Fan-facing match statistics | Google Search |
The biometric layer is equally significant: several host stadiums are using facial recognition for entry — your face is your ticket, processed against the credential database at the gate in under a second.
Across host venues, FIFA deployed Boston Dynamics Spot robots — the quadruped "robot dogs" that have become shorthand for AI-in-the-physical-world — for perimeter security and venue inspection.
The robots conduct automated patrols of restricted areas, with onboard cameras feeding into the venue's security AI. They are particularly useful for spaces that are awkward for human security staff to monitor continuously: tunnel areas, underground service corridors, and stadium perimeters at night.
Several AI systems simulated the entire 104-match bracket before the tournament began. The results don't agree:
| Model | Predicted Winner |
|---|---|
| ChatGPT (Covers, blended ELO + FIFA rankings) | Spain |
| FanDuel Research model | France (3–2 vs Argentina in final) |
| Yahoo Sports / ChatGPT simulation | Brazil |
| DataCamp community model | Brazil |
The disagreement is instructive. Every model is fed the same public data (FIFA rankings, ELO scores, qualifying form, injury reports), but different weighting produces wildly different finals. Spain's tactical efficiency scores highest on ELO-weighted models; France's squad depth wins on injury-adjusted projections; Brazil's historical tournament record dominates history-weighted simulations.
None of them can model Messi's left foot in the 89th minute of a knockout game. That's still football.
What makes 2026 different from previous tournaments isn't any single technology — it's that AI has moved from experiment to infrastructure. The smart ball, the 3D offside system, the body cameras, the analytics platform: none of these are pilots. They are the operational baseline for every match.
For sports AI, the World Cup is what the iPhone was to mobile computing: a moment where the technology stops being something people read about and becomes something 5 billion viewers experience in real time, whether they know it or not.
The 500Hz sensor in the ball doesn't care about football. It just measures spin. But the decision it enables — accurate to the millimeter, rendered in 3D, delivered in seconds — changes how the world's most-watched sport is played and officiated.
That's what AI at scale actually looks like.
