It is no secret that Y Combinator is one of, usually considered the, most successful startup accelerators in the world. But just how successful was revealed on Tuesday. Sam Altman, the President of Y Combinator, published a broad overview of the accelerator’s portfolio stats on Tuesday. It is incredibly short, so here are the details in full:
We get asked a lot for statistics on the YC portfolio. Even though some of these aren’t that helpful , here is the latest update on the numbers we get asked about the most. As always, all the credit goes to the founders.
Total market cap of all YC companies: >$30 billion
Total money raised by all YC companies: >$3 billion
Number of YC companies worth more than $1 billion: 3 
Number of YC companies worth more than $100 million: >20 
Number of companies funded by YC so far: 716
Number of companies in the current batch: 85
Acceptance rate of the current batch: <3%
Number of nuclear energy companies in the current batch: 2
 Intermediate valuations aren’t worth very much, for example. But we don’t keep statistics on total revenue or jobs created, though I expect both numbers would be impressive.
 This is how many companies are currently worth over $1 billion, but even if we never funded another company I think it would at least double and probably triple or quadruple.
 Similar to the note above, this number should go up a lot just from our current portfolio—it generally takes companies a few years to get above this threshold.1
Though these are some impressive stats, it is hardly surprising. Just take a look at Y Combinator’s portfolio:
