Y Combinator: One week left to apply for the Winter 2027 batch
Y Combinator issued a reminder on October 26 that there is only one week left to apply for the Winter 2027 batch, with the official deadline at 8:00 p.m. Pacific Time on November 2. It had previously announced on October 16 that applications for the batch were open, and the batch will take place in person in San Francisco from January to March 2027.
Y Combinator said that founders selected for the batch will receive $500,000 in funding support, as well as more than $12 million in token, credits and partnership benefits; full support from partners who were themselves founders; access to a global top-founder community; and the opportunity to present their projects to thousands of top investors at Demo Day. The official application page confirms that applicants who submit on time will receive a decision by December 11; late applications will still be considered, but there is no specific commitment on when feedback will be provided.
Y Combinator’s official standard deal page shows that the $500,000 investment is split into two parts: $125,000 in the form of a post-money SAFE for a fixed 7% equity stake, and another $375,000 invested in the form of an uncapped MFN SAFE; the investment is committed on the day the company is accepted, without waiting for the batch to begin. The application page also confirms that each selected company can receive more than $12 million in free credits and benefits from partners including OpenAI, Anthropic, AWS, Google Cloud, Azure and Stripe.

ABAB AI Insight
Y Combinator was founded in 2005 by Paul Graham, Jessica Livingston, Robert Morris and Trevor Blackwell, and it initially operated with a model of small investments in exchange for equity and intensive guidance. After the standard deal was adjusted in 2022 to the current $500,000 structure, the fixed 7% portion corresponds to an implied valuation of about $17.86 million, while the MFN SAFE means the eventual equity percentage depends on the company’s next financing terms. This model allows YC to secure a position early while retaining follow-on rights.
On the funding side, the $125,000 is converted directly into fixed equity, while the $375,000 takes the form of a SAFE that waits for conversion in the next round; the credits and benefits come from partner resources rather than YC cash investment. The official application page explicitly lists providers such as OpenAI, Anthropic, AWS, Google Cloud, Azure and Stripe, and these resources can reduce early-stage companies’ spending on compute and infrastructure in an environment of rising AI and cloud-computing costs. YC does not charge a project fee, and the investment begins on the day of acceptance, setting it apart from some accelerators that charge fees or attach milestones.
Compared with accelerators such as Techstars, whose standard deals typically involve a smaller amount in exchange for a fixed percentage of equity plus a SAFE, YC’s combination of a fixed 7% stake and an uncapped MFN makes early dilution more predictable, though total equity still depends on the valuation in later financing. The arrangement of Demo Day for thousands of investors continues its long-standing practice of using a concentrated showcase as a primary fundraising entry point; the expanded scale of partner credits is tied to competition from AI labs in 2026 to offer large token credit packages to YC batches.
This reminder clarifies the one-week window before the application deadline and promises a decision by December 11 for on-time submissions. For selected companies, the combination of a fixed 7% stake and an MFN SAFE changes the certainty of early equity structure, while more than $12 million in partner credits directly affects compute and tool costs, influencing their access to resources during and after the batch.

The fixed 7% locks in an early position, while the uncapped SAFE lets later equity float with valuation.
As partner credit scales expand, early-stage companies shift compute costs from cash to resource exchange.
