The American Arbitration Association (AAA) has expanded its AI Arbitrator to cover business disputes, moving the technology beyond the construction cases where it was first tested. The association announced the expansion on Monday 9 November 2026, saying the service is now available for two-party, documents-only business-to-business cases across industries.

The AI Arbitrator evaluates the merits of a claim, produces explainable recommendations and prepares a draft award. A specially trained AAA human arbitrator then reviews the analysis, makes any revisions and uses independent judgement to issue the final award. The human decision-maker, not the software, has the last word.

From construction pilot to commercial cases

The service debuted on 3 November 2025 for two-party, documents-only construction cases. The AAA said it deliberately started narrow so it could test the technology, refine it and strengthen the governance around it before widening its use.

“By introducing the technology first for a narrower set of construction cases, we could continue testing and evaluating its performance, refining its capabilities, and strengthening the governance processes supporting its use,” said Diana Didia, the AAA’s executive vice president and chief technology and innovation officer.

For the commercial expansion, the technology was trained on cases from more than 20 industries, including healthcare, financial services, energy and technology. The AAA said the system operates within established safeguards designed to support fairness, transparency and accountability, and that case information is held in a closed AI environment: case data and AI-generated outputs are not used to train or expand the underlying model, and the foundational OpenAI models do not ingest case data.

What it costs and how fast it is

Under the AAA’s AI-Led Arbitration Rules, amended and effective from 18 February 2026, the arbitration cost is $2,500 for a claim and $2,500 separately for a counterclaim, covering AAA administration and the human arbitrator’s compensation.

The AAA’s published early results point to resolutions 20 to 25 per cent faster and cost savings of at least 35 per cent, but those figures are expressly limited to two-party, documents-only construction disputes so far, and have not yet been shown for the wider commercial caseload.

The expansion reaches a large part of the AAA’s work. Its commercial-services page reports more than $29 billion in business-to-business claims and counterclaims in 2025. The service remains confined to documents-only disputes, so cases needing live witnesses or complex factual hearings are outside its scope.

A centenary year for the AAA

The AAA, founded in 1926, is marking its centenary in 2026 and describes itself as the largest provider of alternative dispute resolution services in the world. The AI Arbitrator is part of a wider push to apply artificial intelligence to dispute resolution while keeping a human arbitrator in control of the outcome.

The move comes as law firms and legal bodies test AI tools across their work. The question for businesses will be whether the promised speed and savings hold up once the system handles the broader run of commercial disputes, and whether parties are comfortable having an AI system draft the award that a human arbitrator then signs off.
