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.Trader consensus on Polymarket strongly favors "No" at 89.5% implied probability for Pluto's reclassification as a planet by June 30, reflecting the International Astronomical Union's (IAU) enduring 2006 definition, which requires a body to clear its orbital neighborhood—a criterion Pluto fails amid Kuiper Belt objects. Recent buzz from NASA Administrator Jared Isaacman's March 2026 endorsement of potential executive action under President Trump has sparked debate but lacks scientific weight, as the IAU holds sole authority on nomenclature, with no general assembly or vote scheduled before the deadline. New Horizons mission data underscoring Pluto's complexity fuels ongoing dissent but hasn't shifted official status; traders see slim odds of rapid reversal absent formal IAU proceedings.
