Insurance Underwriting

Portfolio-relative metrics for policy pricing, coverage limits, and claims validation

The gap Artalytics closes

Fine-art insurance is a roughly $1B annual-premium market that has priced policies for a century on market value alone. A $2M Basquiat and a $2M emerging-artist work carry identical premiums because underwriters have had no objective signal to differentiate them. Artalytics is that signal — three dimensions of quantitative quality scored within the artist’s own portfolio. AXA XL, Chubb, Berkley Asset Protection, and Huntington T. Block price fine-art risk on market value and appraisal narrative; Artalytics layers a reproducible quality dataset on top — one that exposes fraud-risk signals, substantiates replacement-cost floors, and establishes quality-degradation baselines claims adjusters can stand on.

Why market value alone cannot differentiate risk

Fine-art insurance has three stakeholders the market-value-only model fails in distinct ways.

The underwriter cannot differentiate premium-tier risk from standard risk beyond market value. Two works at the same $2M valuation can have very different forgery-resistance, replacement complexity, and liquidation-market depth — but the rate card treats them identically.

The actuary needs a rating variable defensible at rate-filing level. “Expert opinion on quality” is not a filing-grade rating variable. Without a reproducible quality signal, rate differentiation across quality tiers has no audit basis.

The claims adjuster needs pre-loss baseline documentation. When a damaged work arrives for settlement, subjective “this looked like premium work” memory has to compete with the claimant’s subjective memory. Disputes resolve in 12–18 months. A pre-loss quantitative baseline collapses that timeline.

Market-value-only underwriting was the best available model. It is no longer the only one.

What Artalytics adds to the underwriting stack

Quality-based risk tiering

Each artwork gets a three-dimensional percentile scorecard. That score informs the premium tier:

  • Premium tier (85th+ percentiles) — peak work. Harder to forge, narrower liquidation market, higher replacement complexity.
  • Standard tier (40th–84th) — artist’s baseline output. Typical risk profile.
  • Review tier (below 40th) — simpler execution, easier to replicate. Demands authentication-heavy underwriting.

Rate differentiation remains the actuary’s judgment. The input the rate rests on becomes reproducible.

Replacement-cost floor

The Time & Effort dimension quantifies labor investment: active creation time, observed work intensity, and surface engagement. Those signals supply a labor-cost floor independent of market value — useful for underwriting in markets where market-value comparables are thin or for substantiating high coverage limits in actuarial review.

Pre-loss claims baseline

At policy inception, Artalytics archives the complete scorecard: each dimension, percentile, and confidence level. On damage, the artwork is re-scored. Percentile movement is quantitative — a technical-execution signal moving from the 92nd to the 68th percentile post-damage is measurable evidence of skill-signal degradation, not narrative. The settlement calculation — market value × percentile loss — becomes arithmetic, not negotiation.

Foundation applications by dimension

Time & Effort dimension

Time & Effort supplies creation-effort inputs for replacement-cost-floor calculation. Peak-percentile works establish a higher labor-replacement context independent of market-value comparables.

Skill & Artistry dimension

Skill & Artistry supports authenticity-adjacent risk layers by identifying technical execution patterns that are harder to replicate. It is not a substitute for provenance; it is a consistent quantitative layer alongside it.

Complexity & Detail dimension

Complexity & Detail informs restoration-difficulty estimates. Intricate work can require longer conservation and higher restoration-cost reserves in the claims model.

Actuarial and claims-documentation posture

The actuarial-defensibility posture Artalytics is designed to support:

  • Reproducible rating variable — percentile scores are deterministic functions of canvas metadata.
  • Filing-grade documentation — the private metric set has formal definitions, validation bounds, and traceable computation.
  • Pre-loss baselines — scorecards archived at policy inception support post-damage comparison.
  • Cross-portfolio surveillance — policy-book quality distribution trackable over time.
  • Independent verification — a third party with canvas-file access can reproduce any score.

Formal validation — cross-rater agreement panels, correlation between quality percentile and claim severity — is described in the Validation Framework. Current status is design-stage with defined protocols awaiting pilot data.

What engagement looks like today

Artalytics is pre-commercial. No insurance pilot is in production.

A prospective insurer engagement begins with:

  1. Methodology walkthrough — three dimensions, private metric set, percentile aggregation rules, confidence-level handling. Conducted against the Score Methodology and Validation Framework pages.
  2. Retrospective scoring — on a sample of in-force policies where canvas-file metadata is available, showing how scores would have appeared at underwriting and how post-loss baselines would have behaved.
  3. Rating-variable design discussion — how percentile scores enter the actuary’s rating system; how pre-loss baselines are archived; how claims workflows ingest the post-loss re-scoring.

Early engagements produce joint learning: Artalytics gets real-policy-book feedback on scoring behavior; the insurer gets first-mover access to the quality-signal layer as it matures.

The thesis, stated plainly

Fine-art insurance has priced risk on market value alone because no other reproducible signal existed. That will change within the next rating cycle. Artalytics is the signal that makes quality-adjusted rating actuarially defensible — for the underwriters, actuaries, and claims adjusters whose profitability depends on risk-tiered pricing.
