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 reflects near-unanimous confidence that Pluto will remain classified as a dwarf planet by June 30, driven by the International Astronomical Union's (IAU) unchanged 2006 definition requiring a body to clear its orbital neighborhood—a criterion Pluto fails amid Kuiper Belt objects. Recent remarks from NASA Administrator Jared Isaacman in late April 2026 advocating for reclassification sparked debate but hold no authority, as the IAU alone governs definitions, with its next General Assembly not until August 2027 in Rome and no interim votes scheduled. New Horizons mission data reinforced Pluto's complex geology without altering orbital dynamics, underscoring scientific stability; only an unprecedented emergency IAU resolution could shift this, a highly improbable scenario.
