YC Demo Day Fall 2026: December 2 date, who attends, how to follow

YC Demo Day for the Fall 2026 batch (F26) takes place on Wednesday, December 2, 2026. It is a private, invitation-only event for investors and media, so the public cannot attend or watch a livestream, but most presenting companies can be followed on Launch YC and in the YC Startup Directory. Details below are as of October 30, 2026, from Y Combinator's own pages; the date is worth rechecking nearer the event.

YC Demo Day Fall 2026: date and format

• Date: Wednesday, December 2, 2026, according to the Demo Day page (confirmed October 30, 2026).
• Place: in person in San Francisco. The Demo Day FAQ says the event moved back from the remote format used during COVID.
• Time of day: not published on either page as of October 2026. Invited guests receive logistics directly, so check with YC if you hold an invitation.
• Audience: invited investors and media. The main page puts the audience at about 1,500 investors and media, while the FAQ says about 1,000, so treat the figure as roughly one to one and a half thousand people.

Who gets invited

According to the FAQ, invitations are generated by software from two inputs: an investor's recent investment history in YC startups, and YC's existing relationships with investors. There is no standing guest list, and the event is described as always oversubscribed.

Invitations are non-transferable and cover one person. Colleagues at the same firm can request their own, and an invitation can move to another partner at the same firm. Handing one to non-partner staff is decided case by case.

Investors who want to attend can apply through the form linked from the Demo Day page, which sits at ycombinator.com/demoday. Invited investors then use the separate Demo Day website (demoday.ycombinator.com) to view the companies.

How to follow the batch if you are not invited

YC says companies launch throughout the batch, on its Startup Directory and Launch YC, rather than all on one day. That gives the public three routes:

1. Launch YC: company launch posts, where most presenting startups appear.
2. YC Startup Directory: YC says most of the presenting companies can be found here.
3. Funding coverage after the event: rounds announced by batch companies in the days following December 2. Our Funding section tracks those announcements, and the Events section covers other dated startup events.

The FAQ also points those who cannot attend to the Demo Day website, which lists the companies that presented.

Is YC Demo Day paused or halted?

Search suggestions sometimes pair "YC Demo Day" with "paused" or "halted". Neither the Demo Day page nor the FAQ, both read on October 30, 2026, says anything about a pause or cancellation. They list a December 2 date for F26. If the schedule changes, YC's Demo Day page is where the update would appear first.

What Demo Day is in the YC calendar

Demo Day is the closing event of a YC batch, where the founders present to investors. Companies in the Fall 2026 batch are the ones presenting on December 2.
