TLDR: Generative AI is profoundly reshaping international arbitration, moving beyond administrative tasks to influence core legal strategy, document analysis, research, and drafting. It is increasingly used by counsel to model case outcomes and settlement bands, and by arbitrators to manage voluminous submissions and ensure consistency, though concerns about transparency, legitimacy, and the ‘fine line between support and substitution’ remain paramount.
The legal profession, traditionally cautious of technological advancements, is now witnessing a significant transformation, particularly within international arbitration. What began as an emergency adaptation during the COVID-19 pandemic has evolved into a lasting structural shift, with new technologies, especially generative AI, playing a pivotal role in reshaping legal processes.
AI’s Role in Counsel’s Toolkit:
Counsel teams are increasingly leveraging AI at every stage of arbitration to address cost and time pressures. Predictive coding tools are revolutionizing document production by reviewing, classifying, and prioritizing vast volumes of disclosure with remarkable speed, compressing weeks of work into hours. These tools go beyond keyword searches, learning to cluster themes, recognize fact patterns, and flag outliers, providing clearer paths for building factual narratives. For instance, in a construction dispute, AI might reveal a statistical link between ‘delay’ mentions and ‘Supplier X’ in correspondence, an insight previously unnoticed.
AI also generates interactive issue maps and communication timelines from raw data, enabling counsel to narrow focus, plan strategy, and prepare for witness interviews more effectively. Legal research is undergoing a profound shift, with AI-driven systems understanding context and suggesting relevant authorities, doctrine, or comparative law principles, significantly supplementing traditional manual database reviews. While risks like ‘hallucinations’ and ‘jurisdictional blind spots’ persist, the potential is immense.
In drafting, AI assistance is accelerating the preparation of first-pass memorials, procedural histories, exhibit lists, and submission summaries, allowing lawyers to refine structured outputs rather than starting from scratch. During hearings, real-time AI transcription tools highlight testimony discrepancies or cross-reference witness answers with prior exhibits. Quantum and delay experts in high-value construction disputes are supported by predictive AI tools that model counterfactual timelines or simulate valuations, enhancing the credibility and clarity of expert reports.
Crucially, AI-powered analytics are being adopted by arbitration funders and claimants to model case outcomes and likely settlement bands. These models analyze data from prior awards, tribunal composition, and seat-specific enforcement patterns, offering a sharper lens for clients to decide whether to arbitrate, settle, or walk away.
AI’s Impact on Arbitrators:
The role of arbitrators is also evolving. While their decision-making mandate remains personal, AI tools significantly reduce the burden of digesting voluminous submissions. AI summarization engines condense hundreds of pages of pleadings into side-by-side overviews of each party’s position, particularly valuable in large-scale investor-state or complex commercial arbitrations.
AI assists arbitrators in identifying inconsistencies in the factual record by extracting and highlighting contradictions or gaps in witness statements across different submissions. In disputes with recurring issues, AI can flag when a tribunal’s draft reasoning diverges from its own earlier findings, ensuring consistency and reducing the risk of annulment or enforcement challenges. Some arbitrators are even training personal AI assistants on their prior awards and writing styles to generate first drafts of procedural orders or summarize party positions, allowing them to focus on legal reasoning and case analysis. These AI ‘copilots’ can take over repetitive tasks, provided they are used transparently and ethically, much like tribunal secretaries.
The Fine Line: Support vs. Substitution:
Despite the innovations, serious questions arise regarding the appropriate extent of AI’s involvement. As AI moves closer to substantive reasoning, concerns about transparency and legitimacy become paramount. The use of generative AI in award drafting requires ‘utmost care,’ as reliance on AI to phrase legal conclusions or weigh facts raises questions about who truly decided the case. The article highlights the case of LaPaglia v. Valve1, where a party sought to vacate an arbitral award, citing unexplained factual claims and language patterns inconsistent with the record, raising the unsettling question of whether the award was authored by the tribunal or the tool.
If AI introduces arguments, authorities, or facts not raised by the parties, due process is jeopardized. Arbitrators may struggle to explain AI-generated reasoning, making their decisions opaque and eroding trust if parties perceive an ‘invisible fourth arbitrator.’
However, AI’s role in arbitral administration is widely accepted. Institutions like the ICC and SIAC have adopted digital case platforms (e.g., Case Connect, SIAC Gateway) for case tracking, e-filing, and communication, enhancing efficiency and accessibility without influencing case outcomes.

The article concludes by comparing AI to a ‘junior trainee’—fast, eager, occasionally brilliant, but also prone to misunderstanding, overconfidence, and error. Supervision is key. The arbitration community must carefully draw the line, ensuring that while AI reduces burden and enhances clarity, the legitimacy of arbitration rests on human judgment, not machine prompts. The future of arbitration, therefore, is not artificial but ‘augmented.’
