**Trader sentiment strongly favors the "Under" outcome at 93.5% implied probability for the Mega Charizard X ex card price on September 30, driven by sustained downward pressure on raw singles from recent sets like Phantasmal Flames.** High print runs across the MEGA Evolution era, combined with broader market cooling after 2025–2026 hype cycles and billions of cards produced industry-wide, have kept most non-chase variants in the low-to-mid $30s or below. Recent TCGplayer and eBay data show steady or softening trajectories for comparable promos and ultra rares, with no major release windows, grading surges, or viral collector events scheduled before month-end to reverse the trend. Historical patterns for similar Charizard promos reinforce that short-term spikes are rare without fresh catalyst momentum. While an unexpected social media surge or bulk grading influx could theoretically push prices over the line, the current supply glut and lack of near-term demand drivers make such scenarios unlikely in the remaining window.
