# The AI Arms Race: How Top Carriers Are Transforming Underwriting

Travelers has 20,000+ AI users. AIG is targeting 5x underwriter productivity. PwC surveyed 200+ insurers on actuarial modernization. Here’s what’s happening—and what it means for you.

Something fundamental is shifting in insurance. The largest carriers aren’t just experimenting with AI—they’re deploying it at scale, across their entire operations. And the results are forcing a question every actuarial practice needs to answer: can you afford to wait?

## Travelers: 20,000 AI Users and Counting

In January 2026, Travelers announced one of the largest enterprise AI deployments in financial services: Claude 4 rolled out across their entire global workforce of 30,000+ employees. More than 20,000 professionals now use AI tools regularly.

The scale is staggering: Travelers handles approximately 1.5 million claims annually with payments exceeding $23 billion. With more than half of claims now eligible for straight-through processing—and customers adopting it about two-thirds of the time—the operational transformation is real, not theoretical.

## AIG: Turning One Underwriter Into Five

At AIG’s Investor Day in March 2025, CEO Peter Zaffino unveiled “AIG Underwriter Assistance”—an agentic AI system that’s fundamentally changing how their underwriters work. The results for North America private and non-profit financial lines:

Zaffino’s target: $4 billion in new E&S business by 2030, up from $1 billion in 2024. That’s not incremental improvement—it’s a fundamental shift in what’s possible with the same underwriting team.

## The Industry-Wide Shift

It’s not just Travelers and AIG. PwC’s 2025 Global Actuarial Modernization Survey—their largest yet, covering 200+ insurers across 30+ countries—reveals an industry in transformation.

The top priorities for actuarial leaders:

- Data quality: The foundation for any AI/automation initiative

- Talent acquisition and development: Finding and retaining actuaries

- Process efficiency: Eliminating manual work

- Advanced analytics: Moving beyond traditional methods

The survey concludes that actuarial transformation is “essential for insurers to achieve strategic goals both in the near and long term.” This isn’t optional modernization—it’s existential.

## The Pattern: Amplification, Not Replacement

Notice what these deployments have in common: they’re not replacing underwriters or actuaries. They’re removing the toil that prevents experts from exercising their judgment more often.

At Travelers, claims adjusters aren’t gone—they’re handling more claims with better information. At AIG, underwriters aren’t redundant—they’re reviewing five times as many submissions with data already extracted and prioritized.

The Deloitte perspective on actuarial automation captures it well: AI frees actuaries from routine operational work—coding claims, standardizing unstructured data—enabling them to focus on higher-value strategic activities including modeling, risk identification, and enterprise decision-making.

## What This Means for Actuarial Practices

The carriers are moving. The question is whether actuarial service providers will move with them—or be left behind.

Consider the dynamics:

- Client expectations are shifting. When AIG can process submissions in hours instead of weeks, captive managers and reinsurers will expect similar turnaround from their actuarial consultants.

- Talent is scarce. The PwC survey flags talent acquisition as a top priority. Practices that can do more with their existing team have an advantage.

- Data quality matters more. AI amplifies good data and exposes bad data. Practices need robust intake and validation processes.

The carriers have made their bets. Travelers is spending $1.5B annually on technology. AIG built partnerships with Anthropic and Palantir. These aren’t experiments—they’re strategic commitments.

The practices that thrive in this environment will be those that can match their clients’ transformation with their own. The rest will find themselves competing on price for work that’s increasingly commoditized.
