Y Combinator's directory lists 222 companies in the Summer 2023 batch: 180 Active, 19 Acquired, 0 Public and 23 Inactive. 10% of Summer 2023 is listed Inactive, against 23% across YC batches at least two years old, so more of this batch is still going than in most.

ActiveAcquiredPublicInactive

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.
