When Do YC Applications Open? (2026 Batch Dates & Deadlines)

Short answer

YC accepts applications on a rolling basis year-round, but each batch has a hard application deadline ~6 weeks before the batch starts. In 2025, YC moved to 4 batches per year (Winter, Spring, Summer, Fall). Apply at least 8 weeks before any deadline to maximize your chances — late applications get reviewed but with less time for partner discussion.

The 2026 batch schedule

• Winter 2026 (W26): batch runs Jan–Mar 2026. Application deadline was late October 2025.

• Spring 2026 (X26): batch runs Apr–Jun 2026. Application deadline was late January 2026.

• Summer 2026 (S26): batch runs Jul–Sep 2026. Application deadline ~late April 2026.

• Fall 2026 (F26): batch runs Oct–Dec 2026. Application deadline ~late July 2026.

Exact deadlines are posted at ycombinator.com/apply. YC typically opens the next batch's application 4–6 months before the deadline.

Can you apply between deadlines?

Yes. YC accepts applications 365 days a year. Applications submitted between batch cycles go into the queue for the next open batch. Submitting early (8+ weeks before the deadline) gives partners more time to read, request a video update, and discuss.

There is no advantage to waiting until the deadline. Submitting late is actively worse — late applications get less partner attention.

Late applications

YC accepts late applications up to ~2 weeks after the official deadline, but at that point the interview slots are mostly assigned. Late acceptance is rare but does happen — usually for teams with extraordinary traction.

How long the process takes

• Application submission → interview decision: 2–3 weeks.

• Interview → final decision: same day, usually within 4 hours.

• Acceptance → batch start: 4–6 weeks.

FAQ

Frequently asked questions

Can I apply to YC any time of year?
Yes. The application form is always open at ycombinator.com/apply. Your application is queued for whichever batch you select.
Is it better to apply early or right at the deadline?
Always early. Earlier applications get more partner attention and a higher chance of being asked for a follow-up video before the formal interview decision.
How many batches does YC run per year now?
Four, since 2025: Winter, Spring, Summer, and Fall. This doubled the previous two-batch cadence and roughly doubled the number of accepted companies per year.
What if I miss the deadline?
Apply for the next batch. There is no waiting period or penalty for missing one.
Where do I check the exact current deadline?
ycombinator.com/apply — the deadline at the top is always the next one.
