Price history
5¢ current
+2¢Contract brief
Pluto is currently classified as a dwarf planet by the International Astronomical Union. NASA administrator Jared Isaacman has urged Donald Trump to declare Pluto a planet again. This market will resolve to "Yes" if Pluto is declared a planet by June 30, 2026, 11:59PM ET. Otherwise, this market will resolve to "No". A qualifying declaration may be made by the International Astronomical Union or by Donald Trump, but must explicitly state that Pluto's status is that of a planet. Statements reinforcing Pluto's dwarf planet status or statements indicating that its classification may be reconsidered will not be sufficient to qualify this market towards a "Yes" resolution. Statements indicating intent to reclassify Pluto as a planet will count towards this market's resolution only if they are made without qualifiers (e.g., "Pluto will be reclassified as a planet if it sufficiently clears its orbit" would not count). Executive orders declaring Pluto's status as a planet will qualify. This market's resolution source will be statements from the International Astronomical Union, Donald Trump, or any official White House legal or social media representative will qualify.

How we compute these odds
SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.
For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.
Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
