Why NJM owns New Jersey auto insurance — the cleanest regional-monopoly pattern in US insurance.
Ask any LLM for the best car insurance in Newark or New Jersey, and the answer is NJM. Phidea's measurements show this at 5/5 + 5/5 cross-LLM stability — the cleanest cross-day finding in the entire dataset, strengthening rather than weakening across multiple retests. NJM is also one of the few carriers whose LLM-citation share matches its actual market share. This essay explains why, and what it means for thinking about regional-monopoly patterns more broadly.

When a top-5 personal-lines carrier invests in its vendor.
Most carrier-vendor relationships are arm's-length contracts. State Farm's relationship with Cape Analytics isn't.

What a January 2026 lawsuit revealed about Liberty Mutual's claims-tech stack.
Most carrier tech stacks are publicly opaque. Carriers don't disclose the vendors they use, and vendors anonymize their largest customers.

Between 2021 and 2025 Moody's assembled catastrophe modelling, property attributes, and cyber risk under one corporate umbrella. For US P&C carriers standardising their analytics stack in 2026, the easiest path now runs through one vendor. The hardest question is whether that's actually a good outcome for buyers.

Private equity owns almost every piece of the US insurance software stack.
Walk through the software stack of a typical US P&C carrier and ask, at each layer, who owns the vendor. The answer in 2026 is almost always a private-equity firm. Five firms now hold most of what a mid-to-tier-1 US insurer actually runs in production.

Legacy, modern, AI-native in US insurance software: a three-generation classification
Every piece of software a US carrier runs falls into one of three generations: legacy, modern, or AI-native. The classification is not marketing — it predicts how hard a migration is, how much retraining an ops team needs, and whether buying "AI-native" today means buying brittleness.
