San Francisco Chronicle reporters Susie Neilson, Megan Fan Munce, and Sara DiNatale won the 2026 Pulitzer Prize for Explanatory Reporting for "Burned," a series on how California insurance carriers using algorithmic property-valuation tools systematically undervalued wildfire-destroyed homes, denied claims, and made it functionally impossible for homeowners to rebuild [1]. The Pulitzer Board's citation — Monday afternoon, three p.m. — emphasized the piece's documentation of how the algorithms produced the underinsurance outcome [2].

The paper carried the Pulitzer board's institutional posture Monday — Marjorie Miller reading from the lectern at Columbia while the board's discovery requests against Trump sat on the docket in Florida [3]. Tuesday's register is the inside of the Explanatory category. Burned is the first local newsroom to win Explanatory since 2018, when the Arizona Republic and USA Today Network shared the prize for border-wall reporting [1].

The structural read: algorithmic insurance denial as the under-examined climate-economy register. The Chronicle's series tracked the after-fire claims files of California policyholders whose carriers used third-party valuation software — Verisk, CoreLogic, and proprietary in-house tools — to set replacement-cost estimates that fell systematically below the actual rebuild cost. Carriers used the gap between the algorithm and the construction bid as the ground for partial denials, and the policyholder had no statutory right to inspect the algorithm's inputs [4].

The series' five-part run carried first-person policyholder accounts and the methodology behind the carrier-by-carrier ratio analysis. Neilson, Munce, and DiNatale built the dataset from California Department of Insurance complaint files, public court filings, and direct policyholder solicitation. The reporting moved the state regulator into a 2025 rulemaking process on algorithmic claims-handling [4].

Insurance is a climate story now. The Pulitzer Board's framing on Explanatory put it that way: the carrier's software is the operating layer the disaster victim meets first.
