Y Combinator's directory lists 194 companies in the Spring 2026 batch: 193 Active, 1 Acquired, 0 Public and 0 Inactive. Spring 2026 is less than two years out, so its Inactive share (0%) is not yet comparable with older batches (23% across batches at least two years old).

Statuses are Y Combinator's own listing in its public company directory, read on the date shown. YC's directory can drop companies altogether, so the Inactive counts here are a floor, not a full count of companies that stopped. Acquired and Public are as YC lists them; neither says anything about the price or the outcome for founders.
