Y Combinator runs four batches a year (Winter/Spring/Summer/Fall); its standard deal is $500,000 plus a ~3-month in-person program in San Francisco, with acceptance around 1-2%. The most recent on-time deadline was Fall 2026 on July 27, 2026. YC has not yet officially published the Winter 2027 deadline; based on its usual ~2-month lead time it is projected for around November 2026, so a September 25, 2026 close date is not confirmed.
