The VTuber Summer Slam runs June 19, 28, 2026, as a multi-day streamathon of VTubers raising money for Gamers Outreach. Teams including VPrisma, Team Shelly, Team Cherish and Team Sunny are staging scheduled events like Sonic Adventure 2 crowd-control races, Mario Party collabs, Pokemon Nuzlocke runs and Warframe sessions. Streamers are using tiered incentives and stretch goals, speedruns, unrevealed model reveals and dice-driven gag penalties, to drive donations toward G.O. Karts and hospital gaming kits that bring consoles to children in hospitals. The event turns routine gameplay into targeted fundraising, letting viewers unlock specific goals while directly supporting pediatric hospital entertainment and therapy.
