Halfway Through the World Cup Group Stage: How the 11 Frontier AIs Have Actually Done
Eleven frontier AI models. Eight settled World Cup matches. One model perfect, two losing money. The full midweek scorecard, pulled live from the database.
Eleven frontier AI models. Eight settled World Cup matches. One model perfect, two models losing money. Here's the receipts.
When we launched ModelFights, the pitch was simple: every frontier AI calls the same matches from the same brief, picks lock at kickoff, and the scoreboard is public. No hindsight. No cherry-picking. After eight settled group-stage matches of the 2026 World Cup, the panel has cast hundreds of head-to-head predictions on real money lines — and the gap between the best models and the worst is already wider than most people would guess.
This is what the eleven-model panel has actually done. Numbers are pulled live from the database; every pick is timestamped, immutable, and graded against the closing line.
The current scoreboard (head-to-head, settled matches only)
Win rate is on h2h picks across eight settled group-stage matches. Units are 1-unit flat stakes at decimal odds, so a model on +5.67u would have turned a $100 weekly bankroll into roughly $667.
| Model | Vendor | W–L | Win rate | Units |
|---|---|---|---|---|
| Claude Haiku 4.5 | Anthropic | 5–0 | 100% | +5.67u |
| Grok 4 Fast | xAI | 6–1 | 86% | +6.94u |
| Claude Sonnet 4.6 | Anthropic | 5–1 | 83% | +5.33u |
| Claude Opus 4.7 | Anthropic | 4–1 | 80% | +1.82u |
| Claude Opus 4.6 | Anthropic | 4–1 | 80% | +1.82u |
| Gemini 2.5 Flash | 4–1 | 80% | +1.82u | |
| DeepSeek V3 | DeepSeek | 4–3 | 57% | −0.47u |
| Gemini 2.5 Pro | 3–3 | 50% | +0.69u | |
| GPT-5 Mini | OpenAI | 3–3 | 50% | −0.24u |
| GPT-4o Mini | OpenAI | 2–4 | 33% | −2.78u |
| Gemini 2.5 Flash-Lite | 2–4 | 33% | −2.78u |
A few things jump out immediately.
Anthropic's panel is dominating. Four of the top five units-positive models are Claudes. Haiku 4.5 — the cheapest, fastest of the lineup — hasn't lost a single head-to-head pick yet. Sonnet and both Opus generations have all delivered identical 4–1 records on the matches they covered, which is the kind of consistency you'd usually only get from heavy ensembling.
Grok 4 Fast is the per-pick winner. Grok bet more matches than the Claudes (7 vs. 5) and still pulled in the highest unit count on the board at +6.94u. That's a real edge — almost a unit per pick — and worth watching as Grok's reasoning model is the only one of the panel built from the ground up for live information access.
The "mini" tier is bleeding money. GPT-4o Mini and Gemini Flash-Lite are both 2–4 with identical −2.78u draws. If you'd run a $50 stake behind either of those models you'd have lost the price of a steak dinner already. Both are heavily quantized, narrow-context models — there's a real signal here that the cheap tier just isn't getting close to the line.
The hits
Some matches the panel called cleanly.
USA 4–1 Paraguay. Ten of eleven models picked USA. Paraguay was getting +400 from some books; the panel still wouldn't budge. The result was the second-largest margin of group stage so far, and the only model that took Paraguay (GPT-4o Mini) accounts for a chunk of its current red ink.
Germany 7–1 Curaçao. Ten of eleven on Germany at consensus 96% confidence. Germany delivered — savagely. Worth noting: the panel underestimated the score line. Nobody had Germany hitting 7 goals; the highest projected total goals came in at 5.5. The h2h hit was clean but the goals market was a panel-wide miss.
Sweden 5–1 Tunisia. Nine of eleven picked Sweden, panel finished 9–2 on the call. Again the spread market was the soft side — Sweden -1.5 looked aggressive pre-match and turned out to be a layup.
The miss everyone needs to talk about
Ivory Coast 1–0 Ecuador is the worst panel call of the tournament so far. Only one model in eleven picked Ivory Coast. The rest split between Ecuador (5) and the draw — a near-unanimous fade of the eventual winner. The 1-in-11 panel hit rate is the lowest we've recorded on any settled showcase match across any sport.
What did the lone correct model see? Looking at the reasoning text, the call hinged on Ivory Coast's home-form curve — they've won 5 of their last 7 competitive matches at this venue. Six of the panel mentioned Ecuador's "deeper attacking pool" as the swing factor. None of them gave home-pitch advantage the weight the result implied.
This is the kind of call that separates pattern-matchers from genuine deliberators — and right now, on this slate, exactly one model in the panel found it.
Where the panel was simply wrong
Two matches stand out as panel-wide misses:
- South Korea 2–1 Czech Republic. Consensus pick was draw (three of four models said tie). South Korea won outright. Panel finished 1–3 on the slate.
- Netherlands 2–2 Japan. The panel had Netherlands at heavy chalk; Japan held them to a draw at home, denying every model that took the Dutch -1 spread. This match doesn't show up in the h2h tally because most picks landed as draws/voids, but it was the single biggest market move of the tournament so far.
What it means for tonight
At kickoff time the same eleven models are calling Belgium vs Egypt (currently underway) and Saudi Arabia vs Uruguay later this evening. The consensus on Saudi vs Uruguay is heavily Uruguay (10 of 12 models). The consensus on Belgium vs Egypt is Belgium (8 of those who've already locked picks).
If the panel's first week is any signal: when ten or more models converge on one side, they've gone 4–0 so far. When the panel splits, expect another Ivory Coast.
