Trader consensus on Polymarket prices a 63% implied probability against SpaceX achieving fully reusable Starship—both Super Heavy booster and upper stage caught and rapidly reused without significant refurbishment—before 2027, reflecting persistent technical hurdles despite rapid iteration. The primary catalyst tempering optimism is the May 19 debut of Starship Version 3 (V3) on Flight 12 from Starbase's new Pad 2, featuring elongated tanks, Raptor 3 engines, and enhanced heat shield for over 100-ton orbital payloads. Elon Musk expressed high confidence in V3 enabling full reusability, but acknowledged potential "initial tuning pains" from its radical redesign, with upper stage recovery remaining unproven after prior booster catches. Successful tower catches and post-flight inspections could catalyze a sentiment shift, though FAA approvals and further tests loom as key swing factors before year-end.
