The global insurance sector is undergoing a profound digital transformation, and artificial intelligence is at the centre of this shift. Among the industry leaders driving this evolution is American International Group (AIG), which has recently revealed significant progress in deploying agentic and generative AI across its core operations.
During recent investor disclosures, the company highlighted faster-than-anticipated gains from its AI initiatives — particularly in underwriting throughput, workflow automation, portfolio integration, and operational efficiency. These developments are drawing attention from enterprise AI decision-makers because they demonstrate measurable business impact rather than experimental deployment.
This article explores AIG’s AI strategy in depth — including its orchestration layer, underwriting transformation, portfolio analytics, submission processing acceleration, and the broader implications for the insurance industry.
The Strategic Role of AI in Modern Insurance
Insurance has always been a data-intensive industry. Every policy, claim, and risk assessment relies on analysing vast volumes of structured and unstructured information.
Traditionally, this work required:
- Manual document review
- Risk modelling by actuaries
- Human-led underwriting decisions
- Paper-heavy submission workflows
These processes were time-consuming and resource-intensive, limiting scalability.
Generative AI and agentic systems are changing this model by enabling insurers to:
- Process submissions faster
- Extract insights from documents automatically
- Evaluate risks in real time
- Integrate portfolios efficiently
AIG’s implementation illustrates how AI can move beyond productivity support into operational transformation.
Leadership Perspective: From Aspirational to Operational
AIG’s early AI projections were initially framed as ambitious targets. However, executive commentary has shifted as real-world deployments matured.
Chief Executive Officer Peter Zaffino acknowledged that early expectations were “aspirational,” but later emphasised that internal results exceeded forecasts.
He highlighted a “massive change” in the organisation’s ability to process submission flows without increasing human staffing levels — one of the most economically significant outcomes of the initiative.
This shift in tone signals that AI is no longer experimental within AIG; it is delivering measurable operational leverage.
Embedding Generative AI Across Core Insurance Functions
AIG reports substantial progress embedding generative AI into:
- Underwriting processes
- Claims management
- Submission intake
- Risk evaluation workflows
Its proprietary internal platform, AIG Assist, has already been deployed across most commercial insurance business lines.
The platform uses large language models (LLMs) and generative systems to:
- Extract submission data
- Summarise risk documentation
- Highlight anomalies
- Provide underwriting recommendations
This reduces the manual workload traditionally associated with commercial insurance intake.
Underwriting Capacity Expansion Through AI
One of the most significant outcomes of AIG’s AI deployment is the expansion of underwriting capacity.
Submission Processing Acceleration
Insurance underwriting begins with submission review — analysing broker-submitted risk data, financials, and exposure documents.
Generative AI enables AIG to:
- Ingest documents automatically
- Extract key risk variables
- Summarise complex exposures
- Flag missing information
This dramatically compresses review timelines.
Scaling Without Workforce Expansion
AIG reports it can now process higher submission volumes without adding human capital resources — a direct improvement in operational efficiency and cost structure.
For insurers, underwriting throughput is directly tied to revenue potential. Faster processing means more policies evaluated and written.
Lexington Insurance: A High-Growth AI Use Case
A major proving ground for AIG’s AI capabilities is Lexington Insurance, the company’s excess and surplus (E&S) lines division.
This segment handles complex, non-standard risks — often requiring deeper analysis than traditional policies.
Submission Growth Targets
Lexington has set an ambitious target of reaching 500,000 submissions annually by 2030.
AI is central to achieving this scale.
Current Performance Milestone
The division has already surpassed 370,000 submissions in 2025, indicating accelerated growth enabled by automation and AI-assisted workflows.
Generative systems extract and summarise incoming submission data, allowing underwriters to focus on decision-making rather than document processing.
The Orchestration Layer: Coordinating AI Agents
A defining feature of AIG’s AI architecture is its orchestration layer — a technology stack component designed to coordinate multiple AI agents across workflows.
What Is an AI Orchestration Layer?
An orchestration layer acts as a central command system that:
- Assigns tasks to specialised AI agents
- Manages workflow sequencing
- Integrates outputs across systems
- Ensures consistent decision logic
Rather than operating in isolation, AI agents collaborate across processes.
Decision Support and Cost Reduction
According to AIG leadership, orchestration enables agents to:
- Deliver real-time insights
- Reference historical cases
- Challenge underwriting assumptions
- Improve risk selection quality
This coordination drives both cost savings and decision accuracy.
AI Agents as Underwriting Companions
AIG describes its AI agents not as replacements but as companions to human teams.
These agents:
- Provide contextual data instantly
- Compare submissions to historical risks
- Identify inconsistencies
- Suggest pricing or coverage adjustments
This augmentation model improves productivity while maintaining human oversight.
Importantly, orchestration ensures agents operate across the entire underwriting lifecycle — reducing bias and information silos.
Compressing the “Front-to-Back” Insurance Workflow
Insurance operations involve multiple interconnected stages:
- Submission intake
- Risk evaluation
- Policy structuring
- Pricing
- Claims handling
AIG refers to this as the front-to-back workflow.
AI-Driven Workflow Compression
By embedding orchestrated agents across all stages, AIG has streamlined previously fragmented processes.
Benefits include:
- Faster submission triage
- Integrated risk analytics
- Automated documentation
- Accelerated claims linkage
This end-to-end integration eliminates bottlenecks between departments.
Portfolio Integration Through AI Ontology Mapping
Beyond underwriting efficiency, AIG is leveraging AI for portfolio integration — a complex but high-value application.
Everest Retail Commercial Business Conversion
During the acquisition and conversion of retail commercial portfolios from Everest, AIG deployed generative AI to accelerate account alignment.
AI systems:
- Analysed incoming accounts
- Prioritised renewals
- Identified high-value risks
Management reported this was completed “in a fraction of the time” compared to traditional methods.
Building Insurance Ontologies
A key technical achievement was constructing an ontology of Everest’s portfolio and aligning it with AIG’s own risk frameworks.
What Is an Insurance Ontology?
An ontology is a structured data model defining relationships between:
- Risk categories
- Coverage types
- Industry sectors
- Exposure variables
Creating aligned ontologies enables insurers to:
- Compare portfolios accurately
- Identify overlap or gaps
- Optimise diversification
Ontology mapping is technically complex and often underestimated in cost and effort — making AI acceleration particularly valuable.
Special Purpose Vehicles and Syndicate Expansion
AIG has extended its AI-driven portfolio analytics into specialty insurance structures.
Lloyd’s Syndicate 2479 Launch
The company launched Lloyd’s Syndicate 2479 in partnership with Amwins and Blackstone.
This syndicate structure operates as a special purpose vehicle (SPV), enabling targeted risk underwriting strategies.
AI-Powered Risk Alignment Analysis
To evaluate programme alignment within the syndicate, AIG collaborated with Palantir Technologies.
Using large language models, the firms assessed whether Amwins’ programme portfolio aligned with the syndicate’s risk appetite.
AI analysis included:
- Exposure modelling
- Coverage classification
- Historical loss comparisons
- Portfolio diversification metrics
This automated alignment analysis accelerates SPV structuring and risk validation.
Expanding the SPV Opportunity Pipeline
Leadership reports a strong pipeline of additional SPV opportunities — suggesting AI-enabled portfolio modelling is becoming a repeatable capability.
This has implications for:
- Capital markets integration
