“G2” most commonly refers right now to the upcoming Indian spy thriller film starring Adivi Sesh (the sequel to Goodachari). It is scheduled to start (release in theatres) on 1 May 2026 worldwide.

If by “when does g2 start” you meant something else (like G2 Esports’ next match, a school grade term, or a specific event code-named G2), tell me the context (movie, esports, school, etc.), and I’ll narrow it down.
