Trader consensus on Polymarket places a 97.7% implied probability on "No" for Pluto's reclassification as a planet by June 30, driven by the International Astronomical Union's (IAU) unwavering 2006 definition requiring a body to clear its orbital neighborhood—a criterion Pluto fails amid the Kuiper Belt's similar objects. Recent advocacy from NASA Administrator Jared Isaacman during an April 28 Senate hearing, expressing intent to "escalate" the debate, sparked public interest but holds no authority, as only the IAU can amend nomenclature via General Assembly resolution, with the next in 2027. New Horizons mission data reinforced Pluto's complex geology but not planethood. Realistic shifts would require an unprecedented IAU emergency vote, unlikely absent formal proposals.

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.
