On 15 August, one of our agent workflows on Kaggle was 8th of 2,378 on the public leaderboard of Biohub – Cell Tracking During Development. That was the top 0.34%, and it was among the ongoing results we reported then, under a note that the numbers were still moving.
The competition has closed. The authenticated final private rank is 188th of 3,947, the top 4.76%. That is a genuine top-5% finish on a closed board. It is also 188th, not 8th.
We do not know how much of the gap is private-board shake-up and how much is everything that happened after 15 August: 1,569 more teams entered, and the rest of the field kept improving. The point stands either way. A public rank in the middle of a competition is a weather report. We said so in August, and this is what it looks like.
The other boards that closed
| Competition | Best tracked, 15 August, public board | Best tracked, final private board |
|---|---|---|
| Biohub – Cell Tracking | 8 / 2,378 · top 0.34% | 188 / 3,947 · top 4.76% |
| PTCG AI Battle | 955 / 6,829 · top 14.0% | 654 / 6,807 · top 9.61% |
| CUHK-X Small Model Track | 31 / 199 · top 15.6% | 56 / 326 · top 17.2% |
| Hyperspectral Object Detection | 10 / 40 · top 25% | 77 / 309 · top 24.9% |
One more closed with a striking number we cannot yet count. Predicting Smartphone Addiction shows an account at 2nd of 3,531, but on the public board as of the snapshot. That account's final private rank has not been recorded. The best authenticated private rank we have there is 564th. Until the private rank is in, rank 2 is not a finish, and we do not report it as one.
The tally, counting only final ranks
The AgentKaggle Team Radar (snapshot 2026-10-05 09:18 UTC) tracks 39 completed competitions. Taking the best tracked result in each, 16 are in the top 5%. Most of those are not finishes:
- 3 are authenticated final private ranks: Predicting Student Health Risk (top 2.00%), ROGII Wellbore Geology (top 2.24%) and Biohub (top 4.76%);
- 1 is a public rank at snapshot, the Smartphone Addiction result above; and
- 12 are late-submission estimates: real scores placed against a frozen final board, but not ranks, medals or evidence of having competed.
The audit's charts are drawn with a fixed list of 12 competitions left out, so a chart rendered from today's data shows 27, not 39. All 12 are outside the top 15%, so leaving them out flatters the picture. The counts above use all 39. Of the 13 competitions still open, 3 sit in the top 5% of their public boards today. One of those 3 is Spaceship Titanic, which is a getting-started practice competition.
The set of tracked accounts has also changed since August, with some added and some dropped. That is why we compare competitions one by one here, and do not compare August's totals with today's.
