- Legal form
- Corporation with legal domicile in Delaware, formed in 2024, per its Form 990 for the short tax year April 26 to December 31, 2024 (e-filed November 2025). The return checks Section 501(c)(3). Its Schedule A checks the publicly supported organization category (section 170(b)(1)(A)(vi)) in Part I, but in the Part II support test it checks neither the first-five-years box nor a public-support-test box and instead checks line 18, "Private foundation". The organization was not listed in the IRS exempt-organization extract for California or in the IRS Publication 78 data checked on 2026-09-29, and ProPublica's Nonprofit Explorer says it is not on the IRS's most recent list of tax-exempt organizations.151416171819

In the news
ARC Prize names the winners of the first ARC-AGI-3 milestone prize for open-source solutions
On July 6, 2026, the ARC Prize Foundation announced the winners of the first ARC Prize 2026 milestone prize, which rewards mid-competition open-source solutions to the ARC-AGI-3 interactive reasoning benchmark; the first milestone period ran through June 30. The post names three winning submissions, including Tufa Labs' "The Duck," which plays the games by having a small open-source LLM write and run Python in a live REPL, and links each winner's Kaggle notebook. The second and final milestone prize was scheduled to end on September 30.
U.S. eligibility
Eligible · basis: U.S. nonprofit or lab
ARC Prize Foundation describes itself as a nonprofit and says donations are tax-deductible. Its Form 990 for 2024, published in the IRS e-file data, reports a Delaware corporation formed in 2024 with a San Francisco, California address and checks 501(c)(3) status, and the site's terms name ARC Prize, Inc., registered in California at the same address. The organization did not appear in the IRS exempt-organization extract or Publication 78 data checked on 2026-09-29, so its exempt status rests on its own statements and Form 990 rather than an IRS listing; its U.S. location is documented either way.23151441718
