Odds — the prediction-market price at the moment the AI model answered.

Nuke never makes it out of fnatic's veto — it has been their first ban all 25 times. From there they walk in with a 12-3 record on Cache and 11-3 on Ancient, while BIG are more modest on the same maps at 6-3 and 6-4. Mirage sits at 2-6 for both, so the picks will settle it, and even on Inferno, the map BIG choose most often, fnatic have a 5-3 record.

The form gap is wider still. Over the last 90 days fnatic are 44-21 on maps with a round difference of +146, against 23-18 and +23 for BIG, whose recent defeats came against Nemiga, ranked 52nd, and magic, ranked 23rd. The one series between these two in the past two years went to fnatic 2-1.

We're backing fnatic to win at 2.33, with the obvious caveats attached. The veto is not known yet, and BIG most often open with a ban on Anubis, where fnatic hold a 10-1 record. Part of fnatic's recent run came against Just Players, 88th, and Phantom, 64th, and the price has drifted from 2.08 to 2.33 in a day.

Where we could be wrong

  • The market makes BIG the favourite: 1.69 against 2.33 on this bet.
  • The veto just before the match decides which maps get played: an awkward map in the pool can turn the picture around.
