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”.Recent observational data and emission trends reinforce the current 83.5% market-implied odds against any change. The Climate Clock derives its 1.5°C deadline from the Mercator Research Institute’s carbon budget, which relies on the IPCC AR6 2021 estimate of roughly 400 Gt CO₂ remaining from 2020 and applies a fixed annual emissions rate of 42.2 Gt. With global CO₂ output continuing near or above that level through mid-2026, the displayed countdown (approximately 2 years 332 days as of August) shows no adjustment. Updates occur only when new peer-reviewed budgets or verified annual emission inventories are released; no such revision from authoritative sources is scheduled before year-end. Record 2024–2025 temperatures and persistent high emissions have not altered the underlying methodology or prompted an interim recalculation, leaving the deadline stable through December 2026 absent an unexpected data release.
