Illinois law on the developers of the largest advanced AI systems, signed on 6 July 2026 and taking effect on 1 January 2027.

Refresh of 18 Oct 2026 under the rule that level A needs the instrument's own text or an official register. Re-read the Governor's press release of 6 Jul 2026 on the State of Illinois Newsroom (gov-pritzker-newsroom.prezly.com, listed as the Governor's official newsroom), stored 17 Oct 2026 at its permanent URL. It confirms the bill number, the act's name, the signing on 6 Jul 2026, passage by the General Assembly, the 1 Jan 2027 effective date, the core obligations and the sponsors. It is an announcement of the signing, not the Act's text, so its quotes count as alt-official and the record rests on it alone. The release gives no Public Act number, thresholds (revenue, compute), penalties, enforcing authority or phased dates, and the '104th General Assembly' in official_identifier is not shown in it. The Act's full text on ilga.gov was requested in this run but could not be stored: the connection timed out, as ilga.gov refused connections in earlier runs.
