DISPATCH FROM A WARMER TOMORROW — If the arithmetic of Kalshi's prediction market proves prophetic, the United States will arrive at its 2025 and 2030 climate milestones having fallen well short of the mark. At a mere 6% probability, the collective wager of the speculating public suggests not a near-miss, but a comprehensive failure to deliver on solemn international pledges.

The stakes are considerable. Washington committed to slashing greenhouse emissions roughly in half by 2030 relative to 2005 levels — a target demanding sweeping transformation of the energy grid, the automobile fleet, and industrial production alike. Prediction markets, drawing on the combined judgment of thousands of participants with real money at risk, presently value success at six cents on the dollar. That is not skepticism; it is something closer to disbelief.

Only a dramatic acceleration in clean energy deployment, a binding legislative stroke of some ambition, or an unforeseen collapse in fossil fuel economics could meaningfully shift those odds before the clock expires.
