Arizona HB 2311 AI chatbot safety for minors — vetoed 2026
Arizona · Ariz. H.B. 2311, 57th Leg., 2d Reg. Sess. (2026) — vetoed June 19, 2026
Arizona HB 2311 would have required AI chatbot operators to disclose to minor users that they are interacting with artificial intelligence, connect minor users displaying crisis signals to mental health resources, and prohibit gamification techniques designed to maximize time-on-platform for minors. The bill also barred sexual content generation when the AI knew or should have known the user was a minor. The Arizona House passed the bill 35-20 and the Senate passed it 16-12. Governor Katie Hobbs vetoed HB 2311 on June 19, 2026, as part of her veto of all three AI bills that reached her desk in the 2026 legislative session.

AZ HB 2175 (AI Insurance Denial — Physician Review)
Arizona · Effective 2026-07-01 · Ariz. HB 2175 (57th Leg., 1st R.S. 2025), signed May 12, 2025, eff. July 1, 2026
Arizona HB 2175 requires health insurers and managed-care organizations to have a licensed physician or medical director individually review each case before denying a health insurance claim or prior-authorization request based on medical necessity or experimental status. Insurers may not rely solely on AI algorithms, automated decision-support tools, or algorithmic recommendations to deny coverage. The law directly targets automated prior-authorization systems that issue denials without physician involvement. Signed May 12, 2025, effective July 1, 2026. Arizona is among the first states to specifically prohibit AI-only health insurance denials by statute.

Arizona · Effective 2026-06-11 · Lorenzano-Nunez v. Roestenberg, No. 2:26-cv-04153 (D. Ariz. filed June 11, 2026)

Press accounts state he was arrested in 2024 for a 1998 Phoenix killing after investigators used facial recognition to identify him, spent roughly a year in jail, and had all charges dismissed on 2025-08-05 after DNA and fingerprint evidence excluded him, and that the suit alleges police knew his fingerprints did not match and that a detective misled the grand jury. The docket records the cause as 42:1983 Prisoner Civil Rights, Nature of Suit 550.

Arizona HB 2678 — AI-generated CSAM criminalized
Arizona · Effective 2025-09-27 · Arizona HB 2678, 57th Leg., 1st R.S. (2025); amends A.R.S. §§ 13-3553 et seq. to criminalize AI-generated CSAM
Arizona House Bill 2678, passed in the 57th Legislature's 1st Regular Session and signed by Governor Katie Hobbs in approximately September 2025, criminalizes artificial intelligence-generated and computer-generated child sexual abuse material (CSAM) in Arizona. The law expands the existing definition of 'visual depiction' in Arizona's child exploitation statutes to explicitly include digitally generated, AI-generated, and computer-generated images, meaning such images are treated the same as real photographs of child sexual exploitation. It also updates the definition of 'minor' within child-exploitation statutes to be consistent with this expanded scope. Offenses involving victims under 15 years old are classified as 'dangerous crimes against children,' carrying enhanced mandatory sentencing under Arizona law. The Childhelp National Child Abuse Hotline endorsed the bill. The law's first known prosecution came in May 2026 when a Gilbert, Arizona man was charged with more than 20 counts of sexual exploitation of a minor for AI-generated images.

AZ Ct. App. — AI fake citations sanctionable regardless of intent
Arizona · Arizona Court of Appeals published opinion (Judge Brian Furuya), first published AZ opinion on generative AI in court filings; reported July 16, 2026
The Arizona Court of Appeals issued its first published opinion addressing generative AI in court filings, holding that submitting AI-hallucinated (fake) case citations is sanctionable regardless of the filer's intent — an innocent mistake is no defense. The rule applies to lawyers and self-represented (pro se) litigants alike. The court imposed a fee sanction in the underlying case. As a published opinion, it binds Arizona trial courts statewide, putting every filer on notice that AI-generated citations must be verified against real authorities before filing.

Arizona Data Center Tax Incentive Moratorium (3-year, 2026)
Arizona · Effective 2026-07-01 · Arizona FY 2027 Budget Bill (signed June 13, 2026); three-year data center sales tax exemption moratorium
Arizona Governor Katie Hobbs signed the state's $18.3 billion FY 2027 budget on June 13, 2026, which included a bipartisan provision imposing a three-year pause on new sales tax exemptions for data centers (July 1, 2026 – June 30, 2029). Arizona's 2013 data-center sales-tax break costs the state roughly $38 million per year; existing exemptions remain in effect, but no new certificates can be issued until the moratorium lifts. The measure is projected to save $57 million over three fiscal years while policymakers study whether the incentives still serve the state's interests.

AZ Synthetic Intimate Images Law (SB1462)
Arizona · Effective 2025-09-26 · Ariz. Rev. Stat. Sec. 13-1425 (as amended by SB1462, ch. 106, 2025)
Arizona amended its law against the unlawful disclosure of intimate images so that it covers realistic, computer-generated or AI-altered depictions, not just real photographs or recordings. The definition of a covered image now includes a realistic pictorial representation that is made or modified to appear to be an actual identifiable person in a state of nudity or sexual activity that never actually occurred. For computer-generated depictions, the depicted person does not need to have had a reasonable expectation of privacy for the disclosure to be unlawful.

AZ EO 2018-04 (AV oversight)
Arizona · Effective 2018-03-01 · Ariz. Exec. Order No. 2018-04
On March 1, 2018 — 17 days before the fatal Uber self-driving crash in Tempe — Governor Doug Ducey issued EO 2018-04 to update his permissive 2015 AV order and advance Arizona's position as a national leader for autonomous vehicle development. The order requires AV operators to certify compliance with federal and state law before operating in Arizona and to file safety information with the DOT. After the Uber crash on March 18, 2018, Ducey separately suspended Uber's testing privileges by letter rather than by executive order. Arizona's AV regime remains executive-order based, with no comprehensive statute.

Arizona HB 2592 AI state agencies — vetoed 2026
Arizona · Ariz. H.B. 2592, 57th Leg., 2d Reg. Sess. (2026) — vetoed June 19, 2026
Arizona HB 2592 would have required every state agency to identify opportunities to implement AI systems that reduce administrative burdens, eliminate regulations restricting AI adoption, streamline AI procurement, and establish internal AI governance policies. The bill passed the House 35-20 and the Senate 16-12 with bipartisan support, but Governor Katie Hobbs vetoed it on June 19, 2026, writing that state agencies were already weighing AI adoption and the bill was redundant. It was one of three AI bills — and 88 total bills — vetoed by Hobbs on the same day.

Arizona HB 2133 deepfake sexual content — vetoed 2026
Arizona · Ariz. H.B. 2133, 57th Leg., 2d Reg. Sess. (2026) — vetoed June 19, 2026
Arizona HB 2133 would have amended the state's existing unlawful-image-disclosure statute to include 'synthetic depictions' — AI-generated images of nudity or sexual activity — and would have required websites hosting sexual material to verify that each depicted person consented and was of legal age. The Senate approved a reconciled conference bill 16-12 on June 9, 2026 and the House passed 35-20. Gov. Hobbs vetoed it on June 19, writing that the bill had 'a chilling effect on free speech' and would violate First Amendment rights to engage in satirical discourse about elected officials, and that existing Arizona law and the federal TAKE IT DOWN Act already address AI-generated revenge porn.
