One prediction market prices this story:
- Before 2050 — the market puts it at 66%, with $3 traded in the last 24 hours, closing 1 Jan 2050. The outcome is Yes if global temperatures hit or pass 2.0°C above pre-industrial levels in any single year before January 1, 2050. The outcome is No if that threshold remains unbreached by the deadline. Readers often mistake this for a long-term average rather than a specific annual peak.
Odds are the market's probability that the outcome happens, updated every few minutes. They are information about what traders expect, not a forecast we make and not investment advice.
