AI is reshaping underwriting efficiency for brokers in ways that are measurable, unevenly distributed, and sometimes overstated. The short answer: carriers using AI-assisted underwriting are reporting efficiency gains in the range of 15-25%, and brokers who adapt their submission practices to these systems are seeing faster quotes, higher placement rates, and less rework. But the gains are not automatic, not evenly spread across lines of business, and they come with real trade-offs that brokers need to understand rather than simply celebrate.

## The Direct Answer: What the Numbers Actually Show

The clearest public data point comes from W. R. Berkley, whose CEO stated that the company is seeing more than 20% improvement in underwriting efficiency from AI adoption. That figure matters because W. R. Berkley is a large, disciplined specialty carrier — when a company like that puts a number on it, the gain is real and audited internally, not a marketing claim. Travelers has separately reported AI-driven improvements in both claims handling and underwriting throughput during its quarterly earnings discussions through 2025 and into 2026.

AIG offers another useful benchmark. CEO Peter Zaffino has been one of the most vocal advocates of generative AI in commercial insurance, and AIG reported roughly a 15 percentage-point increase in underwriting data collection and accuracy after deploying GenAI tools across its underwriting workflow. For brokers, that number translates directly into fewer back-and-forth emails asking for missing loss runs, supplemental applications, or COI details — because the carrier's system now extracts and validates that data automatically at submission intake.

McKinsey's investor-focused research on AI in insurance frames the broader picture: the technology compresses underwriting cycle times, improves risk selection consistency, and shifts underwriter time away from data gathering toward judgment calls on complex risks. For brokers, the practical consequence is that well-prepared submissions move faster while poorly prepared ones get filtered out earlier and more bluntly than before.

## Why This Matters Specifically to Brokers, Not Just Carriers

There is an uncomfortable truth in the coverage of this topic — InsuranceNewsNet described it as "AI's dual reality: efficiency for insurers, disruption for agents." The efficiency gains accrue first to carriers, and some of those gains come precisely from reducing dependence on manual broker interactions. Straight-through processing, automated triage, and AI-driven appetite matching all reduce the number of submissions that ever reach a human underwriter's desk as a broker-mediated conversation.

At the same time, brokers who understand how these systems work can position themselves advantageously. When a carrier's AI scores a submission within seconds of receipt, the quality and structure of what the broker sends determines whether the submission gets prioritized, quoted accurately, or kicked back. Brokers operating with modern digital submission workflows report materially better hit ratios with AI-forward carriers than those still sending PDFs by email.

The vendor ecosystem is also building specifically for the broker side. Vertafore launched an AI agent aimed squarely at MGA submission delays, targeting the bottleneck where wholesale brokers wait days or weeks for carrier responses. Microsoft's cloud blog documents agentic AI deployments across insurance operations that handle routine servicing tasks end-to-end. These tools exist because the market recognizes that broker-side friction is now one of the largest remaining inefficiencies in the placement chain.

## How AI Underwriting Efficiency Actually Works in Practice

Understanding the mechanics helps brokers work with these systems instead of against them. Modern AI underwriting pipelines typically operate in four stages. First, ingestion: documents such as ACORD forms, loss runs, financial statements, and website data are parsed by document-intelligence models rather than keyed in manually. Second, enrichment: third-party data — geospatial catastrophe scores, credit signals, regulatory filings, news sentiment — is appended automatically. Third, scoring: a model estimates expected loss cost, appetite fit, and pricing range, often producing a referral recommendation. Fourth, decisioning: risks below defined thresholds get straight-through quotes; complex risks route to senior underwriters with a pre-assembled summary.

Each stage removes hours of work that previously sat with either the underwriter or the broker. A commercial property submission that once took three to five business days for initial review can receive an indicative quote in minutes if the data is clean. Travelers' public commentary on Q2 results attributed measurable cycle-time reductions to exactly this kind of pipeline. United Wholesale Mortgage's CTO has described parallel dynamics in mortgage underwriting, where AI handles document verification and income calculation so humans focus on exceptions — a pattern commercial P&C is following closely.

For brokers, the practical takeaway is that the AI reads everything you send and nothing you don't. Incomplete submissions no longer sit in a queue waiting for a friendly underwriter email; they fail validation instantly and may be deprioritized algorithmically.

## Comparison: Traditional Broker Workflow vs. AI-Enabled Workflow

| Feature | Traditional Submission Process | AI-Enabled Submission Process |
| --- | --- | --- |
| Initial carrier response | 3-10 business days | Minutes to 24 hours |
| Data entry burden | Manual re-keying by carrier staff | Automated document extraction |
| Missing information handling | Email chains over days | Instant validation flags at intake |
| Quote accuracy on first pass | Often revised after clarification | Higher first-pass accuracy via enriched data |
| Underwriter attention allocation | First-come, first-served queues | Risk-scored prioritization |
| Broker differentiation | Relationships and persistence | Data quality plus relationships |
| Complex risk handling | Full manual review | AI pre-summary, human judgment on exceptions |

The table oversimplifies in one important way: relationship capital still matters enormously on large or unusual accounts. AI handles the commodity middle of the market efficiently; the top and bottom of the complexity curve still run through experienced people. Brokers should read this as a barbell, not a replacement curve.

## Practical Steps Brokers Should Take Now

First, audit your submission hygiene. If your agency still submits partial ACORD forms, stale loss runs, or scanned applications without structured data, you are actively penalized by AI-triaged carriers. Build a standard intake checklist per line of business and enforce it internally before anything leaves the shop.

Second, adopt broker-side tooling deliberately. Platforms from vendors such as Vertafore, Salesforce (which publishes guidance on AI in underwriting workflows), and various insurtech submission-management products can pre-validate submissions against carrier appetite profiles. Even a lightweight rules-based checker catches the majority of rejection causes before submission.

Third, segment your carrier panel by AI maturity. Ask each carrier directly about straight-through quoting thresholds, required data formats, and API availability. Route small, clean, commodity risks to AI-forward carriers where speed wins the account; route complex or distressed risks to carriers with deep specialty underwriting benches where human expertise still decides outcomes.

Fourth, retrain producers on what differentiates them. When carriers quote commodity risks in minutes, the broker's value concentrates in coverage design, negotiation on ambiguous exposures, claims advocacy, and portfolio-level advice. Producers who cannot articulate value beyond access to markets will feel the squeeze that InsuranceNewsNet's "disruption" framing describes.

Fifth, track your own metrics. Measure average days-to-quote, first-pass completeness rate, and hit ratio by carrier. Without baseline numbers you cannot tell whether AI-era changes are helping or hurting your book.

## Common Mistakes and Overstatements to Avoid

The biggest mistake brokers make is treating AI efficiency as either irrelevant or total. It is neither. Some widely repeated claims deserve skepticism. Vendors frequently cite efficiency percentages without defining the baseline — a "30% faster" claim measured against a deliberately slow manual process tells you little. Agentic AI, the current industry buzzword, is genuinely useful for narrow, well-defined tasks like submission status tracking, but claims that autonomous agents will run placements end-to-end remain aspirational. Stock Titan's coverage of XChange TEC's proposed deal to put AI agents into claims handling illustrates how early and speculative some of these deployments still are.

History also counsels caution. The subprime mortgage crisis was partly enabled by automated underwriting models that performed well in calibration samples and badly in stress conditions. Models trained on benign years systematically underestimated tail risk. Commercial insurance underwriting models carry the same structural weakness: they learn from historical loss data, and the next major loss driver — cyber aggregation, climate volatility, litigation trends — may not be well represented in training data. Brokers should treat model-generated quotes as starting points subject to professional scrutiny, especially on accumulations and emerging exposures.

Another common error is neglecting data privacy and accuracy obligations. When you feed client information into AI-powered platforms, you take on responsibility for understanding where that data goes, how it is retained, and whether extracted data contains errors that propagate silently into quotes. An AI-extracted wrong payroll figure produces a confidently wrong premium.

## Costs, Pricing, and the Economics for Brokerages

Broker-side AI tooling costs vary widely. Lightweight submission-validation and CRM-embedded AI features typically run $50-$200 per user per month as add-ons to existing agency management systems. Dedicated submission-intelligence platforms and AI agent services generally price between $500 and several thousand dollars monthly depending on submission volume, with enterprise MGAs negotiating custom contracts. Carrier-side costs are irrelevant to brokers directly but shape the economics indirectly: carriers capturing 20% efficiency gains have margin room to compete on price for clean, algorithm-friendly risks — which means brokers delivering clean submissions effectively earn discounts for their clients.

The return calculation for a mid-size brokerage is straightforward arithmetic. If a commercial producer team submits 1,000 risks annually and AI-enabled preparation cuts 45 minutes of rework per submission while improving hit ratio by even two percentage points, the recovered producer time and incremental commission comfortably exceed a five-figure annual software spend. But brokerages with low submission volumes or highly specialized books may see weak returns and should start with free tiers or carrier-provided portals before committing.

## When to Act and What to Watch Through Late 2026

Act now on submission hygiene and carrier segmentation — those require no new technology and deliver immediate benefit. Pilot broker-side AI tools in the second half of 2026 once you have baseline metrics established. Delay heavy investment in agentic AI until vendors demonstrate audited results rather than demos; the Microsoft-documented enterprise deployments suggest the capability is maturing quickly, but procurement discipline still beats hype-chasing.

Watch three indicators through the remainder of 2026. First, whether more carriers follow W. R. Berkley and Travelers in publishing quantified efficiency figures, which would signal that AI underwriting has moved from experiment to standard practice. Second, how regulators respond to model-driven underwriting decisions, particularly around explainability and adverse-impact testing — new compliance requirements could slow deployment in personal lines. Third, consolidation among insurtech submission platforms, which will clarify which tools will still exist in two years.

The honest bottom line: AI underwriting efficiency is real, quantified at 15-25% by credible carriers, and steadily transferring competitive pressure onto brokers' submission quality and advisory depth.
