Recent staging server activity on Dota 2's test branches, which began ramping up in late September, signals Valve is preparing to roll out Dark Carnival Act 2 imminently, supporting the 77.5% market-implied odds for a release by year-end. The Halloween-themed event, launched in June with its first chapter and story progression similar to Crownfall, has built steady community momentum through phased unlocks and rewards. Traders view the timing as favorable for a fall drop, potentially aligning with October holiday vibes or December tournament windows like DreamLeague, though Valve's unpredictable cadence leaves room for minor delays. Key catalysts ahead include further test server builds and any post-TI cosmetic or narrative announcements.
