**Mega Gengar ex SIR (#284/217) from the January 2026 Ascended Heroes set trades as a top chase card in the current Mega Evolution era, fueled by Gengar’s massive fanbase, striking special illustration artwork, and low pull rates that sustain collector demand.** Raw near-mint prices have hovered in the $940–$1,050 range in late August 2026, with recent sales clustering around $950 and modest 30-day softening after earlier gains. This positioning explains the 71% market-implied probability for “Under” $1,051.08 by September 30, as traders price in typical post-hype stabilization roughly eight months after release, where supply gradually absorbs early frenzy without fresh major catalysts. Comparable high-end SIRs often see consolidation or minor corrections once initial sealed-product inflows slow, and no imminent set releases or competitive shifts appear poised to reverse the recent flat-to-down trajectory in the next month. The threshold sits near current blended market levels, making short-term downside or sideways movement the consensus view among capital-backed traders.
