Three Moving Pieces, One Calendar
US AI regulation in 2026 is not one thing — it is three overlapping fronts, each with its own risks. For compliance, product, and legal leaders running AI features in multiple US states, the picture looks like this:
- California SB 53 — “Transparency in Frontier Artificial Intelligence Act” — effective January 1, 2026.
- Colorado AI Act (SB 24-205) — a broad algorithmic-discrimination statute — effective June 30, 2026 (delayed from February 1, 2026 via SB 25B-004).
- Federal executive order of December 11, 2025 — “Ensuring a National Policy Framework for Artificial Intelligence” — launches a DOJ-led AI Litigation Task Force to challenge state laws on preemption grounds.
These move on different tracks, but they interact. A team shipping an AI product into the US market in 2026 needs a stance on each one — and should not assume the federal push will erase state obligations before the deadlines hit.
California SB 53: Transparency for Frontier Developers
California Governor Gavin Newsom signed SB 53 — the Transparency in Frontier Artificial Intelligence Act — on September 29, 2025, with an effective date of January 1, 2026. Per the WilmerHale analysis, the law targets a specific class of developers:
- “Large frontier developers” — those with annual gross revenue exceeding $500 million.
- Building “frontier models” — foundation models trained using more than 10²⁶ integer or floating-point operations.
These developers must publish a risk management framework, produce transparency reports, and disclose certain information about their model training and safeguards. SB 53 is narrow — it does not regulate every AI system — but it hits the companies most visible in the generative-AI market.
Several other California AI laws also took effect on January 1, 2026, including AB 2013 (training-data disclosure for generative AI developers) and SB 243 (chatbot disclosure rules). The King & Spalding roundup treats January 1, 2026 as “the new year, new rules” moment for AI in California.
Colorado AI Act: Delayed, Not Dead
Colorado’s SB 24-205 — the Colorado AI Act — was the first comprehensive US state AI law, signed in 2024. Its stated goal: require developers and deployers of high-risk AI systems to use reasonable care to protect consumers from algorithmic discrimination.
The original effective date was February 1, 2026. During a special legislative session in August 2025, Colorado passed SB 25B-004, pushing the effective date to June 30, 2026. Baker Botts’ implementation alert explains that the delay gives developers, deployers, and the Colorado Attorney General more time to finalise operational details — not a reprieve from the substance.
When it kicks in, the Colorado AI Act will require:
- A documented risk management programme for high-risk AI.
- Impact assessments covering known or reasonably foreseeable risks of algorithmic discrimination.
- Notice to consumers when they are subject to a consequential decision made by a high-risk AI system.
- A right to appeal or correct discriminatory outcomes.
- Reporting to the Attorney General where discrimination is discovered.
For enterprises deploying AI in employment, housing, lending, insurance, education, or essential services, this is the most operationally demanding US state AI regime to date.

The December 11, 2025 Executive Order
On December 11, 2025, President Trump signed an executive order titled “Ensuring a National Policy Framework for Artificial Intelligence”. As summarised by Sidley Austin and Morgan Lewis, the order does three things that reshape the compliance landscape:
- DOJ AI Litigation Task Force — the Attorney General is directed, within 30 days, to stand up a task force whose sole responsibility is to challenge state AI laws inconsistent with the order’s policy, on grounds of unconstitutional interstate-commerce regulation or federal preemption. California’s transparency laws and Colorado’s algorithmic-discrimination statute are named explicitly.
- Federal agency pressure — FCC to explore a federal reporting and disclosure standard, FTC to issue a policy statement on how deceptive-practices law applies to AI, and Commerce to evaluate state laws that “conflict” with federal AI policy by March 11, 2026.
- Federal funding conditions — review of potential conditions on federal funds flowing to states, intended to discourage “onerous” state AI regimes.
Crucially, an executive order is not itself preemption — it can launch litigation and pressure, but state laws remain in force until a court rules. The EPI policy tracker and NPR’s legal analysis both stress that the legal outcome is uncertain.
What Multi-State AI Teams Should Actually Track
For compliance, product, and legal leaders, the 2026 calendar is not a choose-one-battle situation. The practical playbook:
- [ ] Treat SB 53 as live. If you meet the frontier-developer threshold, publish the risk framework and transparency report. If you sell to one, expect contractual pass-through.
- [ ] Plan Colorado go-live for June 30, 2026. Build the risk management programme, impact assessment template, consumer notice, and appeal mechanism now — don’t bet on a second delay.
- [ ] Track the DOJ task force. Monitor enforcement actions, DOJ public filings, and FTC / FCC notices for signs the federal pushback reaches your use case.
- [ ] Watch state lookalikes. Texas, Illinois, Virginia, and others have AI measures advancing; update your state matrix quarterly.
- [ ] Document your model and deployment. The common denominator across all three tracks is documentation: training, evaluation, intended use, risk controls. Build that file once and reuse it.
Frequently Asked Questions
Is the Colorado AI Act still happening?
Yes. Colorado SB 25B-004 delayed the effective date of the Colorado AI Act from February 1 to June 30, 2026, but kept the substance in place. Companies with high-risk AI systems in Colorado should treat June 30, 2026 as the real deadline and finish implementation before it.
Who does California SB 53 actually apply to?
SB 53 targets “large frontier developers” — those with annual gross revenue above $500 million — building foundation models trained with more than 10^26 integer or floating-point operations. Most mid-size AI companies and downstream deployers are not directly in scope, but may be pulled in via contracts, partnerships, or disclosure expectations from their frontier-model vendors.
Does the December 2025 executive order preempt state AI laws?
Not by itself. The December 11, 2025 executive order establishes a DOJ AI Litigation Task Force and directs federal agencies to act, but courts must ultimately decide whether specific state AI laws are preempted. Until a ruling or new federal law, Colorado, California, and other state AI statutes remain in force.
