What Chalearn does
Mission
Educate the public with scientific competitions and related events
As stated on its FY2025 Form 990-EZ.
Programs
FAIR UNIVERSE: This is a program in collaboration with Lawrence Berkeley Labs: https://fair-universe.lbl.gov/. The collaboration is building a large-compute-scale AI platform for the hosting of large scientific datasets, models, and machine learning competitions to drive forward discoveries in high energy physics and cosmology. The initial focus is on discovering and minimizing systematic uncertainties in High Energy Physics through a sequence of challenges that will bring together researchers across physics and machine learning. ChaLearn sponsors a PhD student and a freelance engineer. The expenses this include the salary of the PhD student (via a donation made to Université Paris-Saclay), and prizes and travel awards given to challenge participants and organizers.

This year we sponsored the Face anti-spoofing, ICCV 2025 https://sites.google.com/view/face-anti-spoofing-challenge/welcome. We also supported the creation and annotations of a new dataset for diadic interactions (work in progress).
$5,371 spentof which $4,515 as grants6% of program spendingPAPER REVIEW: This is a program on automated reviews of scientific papers. This year we worked on a paper to help verify that camera-ready papers include corrections agreed upon between authors and reviewers (work in progress). We supported the internships of students.

This year, we rolled out the new benchmark platform codabench.org, in replacement for Codalab. Together Codalab and Codabench hold a strong position compared to Kaggle and Tianchi: https://mlcontests.com/state-of-competitive-machine-learning-2025. The code is open-sourced: https://github.com/codalab/codalab-competitions/issues. We are editing a book on challenges and benchmarks: https://sites.google.com/chalearn.org/book/home. We supported the editing work.

The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $113k to $196k (+74%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
100% of CHALEARN’s revenue is contributions — more reliant on donations than three-quarters of its peers (57% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 5 reported years ran a deficit.

Who funds it, year by year
2019 → 2021: the base held at 1 funder, grant income fell $36k → $19k.
1 of 2 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 19% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of CHALEARN’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
CHALEARN leans on a few funders — its largest provides 81% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund CHALEARN.
Largest funder’s share by year: 2019 100% · 2020 100% · 2021 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
CHALEARN draws 100% of its grant income from funders outside California, across 1 state in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $32k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
CHALEARN runs a healthier operating margin than three-quarters of the 16,849 education nonprofits its size.

These figures are read directly from IRS Form 990 / 990-PF e-file XML: this organization’s own return for FY2025 (financials across 2021–2025), and the filings of 2 funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. Trends on this page end at FY2023, the last fiscal year that has finished arriving; later years are shown and marked, and move no figure.
