Prediction Markets Expose What Insurance Already Priced

You can now bet money on whether a wildfire will burn down a specific neighbourhood.

The market works like any other prediction market. You buy shares in "yes, the fire spreads here" or "no, it stops," and the price moves as more people trade. Survivors of California's recent fires have called it morally reprehensible and worry the markets will create incentives for arson.

Everyone in this argument agrees that arson is already rational. They just disagree about whether pricing it makes it worse. A property owner in a high-risk zone can already buy fire insurance, and that price reflects the risk.

An insurer already knows wildfire arson happens. They price for it, deny claims when they can prove it. Have known for decades that some people burn their own property when it's worth less than the insurance payout. The prediction market does one thing differently. It makes the calculation visible and turns an implicit probability into an explicit price.

Survivors aren't actually afraid the markets create arson. They're afraid the markets prove it was always economically sensible. That's much worse psychologically because it means the incentive structure was never the problem. The real problem was that we built valuable property in places fire naturally goes, insured it against the thing that naturally happens there. Then acted shocked when the math worked out.
