Each market asks whether the “Deadline” to limit global warming to 1.5°C shown by the Climate Clock (https://climateclock.world) will change before that market's listed date. A market resolves to “Yes” if, at any point on or before its listed date, 11:59 PM ET, the Climate Clock's published 1.5°C Deadline is more than 30 days earlier or more than 30 days later than July 22, 2029. Otherwise, that market resolves to “No”. The Climate Clock's 1.5°C Deadline is published as a machine-readable timestamp in its public data feed at https://api.climateclock.world/v2/clock.json (the “timestamp” value of the carbon-deadline module), which is the same target the on-site countdown at https://climateclock.world displays. As of this market's creation, that Deadline is July 22, 2029 (timestamp 2029-07-22T16:00:00+00:00). The ordinary second-by-second ticking of the countdown toward the Deadline does not constitute a change; only a change to the published Deadline date itself qualifies. Because a qualifying change is permanent once published, every market with a listed date on or after the change will resolve “Yes”, and markets whose listed date has already passed without a qualifying change will have resolved “No”. If the Climate Clock and its public data feed both become permanently unavailable before a qualifying change is published, all unresolved markets will resolve to “No”.Trader consensus on the Climate Clock's 1.5°C deadline remaining unchanged through December 31, 2026, at a 90.5% implied probability stems primarily from the Mercator Research Institute's stable carbon budget calculation, anchored to the IPCC AR6 estimate of roughly 400 GtCO₂ from 2020 for a 67% chance of limiting warming. This is divided by an assumed steady annual emissions rate near 42 GtCO₂, with recent Global Carbon Project data confirming no abrupt acceleration or mitigation surge that would prompt a recalculation. The clock updates quarterly but major deadline shifts exceeding 30 days require substantial revisions to the budget or emissions trajectory, which lack near-term catalysts before late 2026. A new IPCC assessment or sharp emissions drop could still alter the July 22, 2029, target, though historical patterns show such changes occur infrequently.
