- Current data slightly favors Gragas, but the sample is too limited for a strong conclusion: Gragas wins 54.8% of 155 games (95% range 47.0–62.5%).

- Neither side reliably wins the lane: the average gold difference at 15 minutes is 259, within the margin of error (110 games).

How we calculate this
Games: ranked Solo/Duo and Flex games on the North America server from the patch shown. Remakes (games under 5 minutes) are excluded.
A game only counts when Gragas and Jax played the same position on opposite teams, so roaming, lane swaps within a team or a champion merely being in the same game never count as this matchup.
The 95% range is a Wilson score interval. Confidence comes from how wide that range is: within ±3 points is very high, ±5 high, ±8 moderate, anything wider low. Below 20 games a matchup is not classified at all.
Expected win rate combines both champions’ win rates in this lane (same games and filters) with the log5 formula: E = A(1−B) / (A(1−B) + B(1−A)). Matchup effect = observed − expected.
"What changes" compares Gragas's choices in this matchup with the same champion's other games in the same lane, and lists a change only when it is at least 3 points and statistically significant (two-proportion z-test, |z| ≥ 2, 20+ games).
Results are not split by rank: the sample per rank is too small for honest per-rank matchup numbers.

Best Gragas Build vs Jax
Usual Gragas build (Top)
90.0% win rate · 10 games
Against Jax
Not enough matchup-specific build data: only 8 of 54 Gragas games against Jax carried a complete build, which is too few to recommend an item path from. Use Gragas's standard build instead.
- Gragas usually completes Rod of Ages first, at 11.9 min (median of 44 games).
- Jax usually completes Trinity Force first, at 14.2 min (median of 83 games).
- Skill priority: Q > E > W — the same as usual.
Builds are ranked by the lower edge of their win rate range, not the raw win rate, so a build seen in a handful of wins never outranks a proven one.
