This market will resolve to “Yes” if any sitting Member of Parliament (MP) in the Australian House of Representatives announces that he or she will join Pauline Hanson’s One Nation between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. An announcement that the individual will transition from independent status or another political party to One Nation will qualify only if the individual is a sitting MP in the Australian House of Representatives at the time of the announcement. This market will resolve based on a qualifying announcement made within the specified timeframe. Once such an announcement is made, whether or when the individual subsequently joins One Nation will not affect the market’s resolution. The primary resolution source for this market will be official information from the relevant MP or their official representatives; however, a consensus of credible reporting may also be used.**Recent developments show One Nation attracting interest from disaffected Coalition figures amid its polling surge and internal Coalition strains.** Barnaby Joyce defected from the Nationals in December 2025, while the party secured its first elected lower-house seat via the May 2026 Farrer by-election and saw primary support rise to the mid-20s or higher in multiple polls. Speculation persists around sitting members, including Western Australian Upper House MP Ben Dawkins expressing interest in a switch and public comments from Pauline Hanson naming Senator Alex Antic as a potential fit, though she has warned against “opportunist” Coalition defectors. These signals, combined with ongoing Coalition polling weakness and crossbench realignments, underpin traders’ assessment that another sitting MP joining remains more likely than not before year-end, without confirmed commitments locking in the outcome.
