**How to read these figures**

They come from announced rounds. Large rounds are almost always announced and many small ones never are, so the true typical round is probably a little smaller than shown, most of all at pre-seed and seed. Every round behind them is in the record with its source. [How we read rounds](https://millionrounds.com/methodology).

## Q&A

How big is a typical Series D round in AI?

The median is $150M, from 49 Series D rounds announced in AI in the last twelve months. Half of them raised between $70M and $400M; one in ten raised more than $840M.

Which rounds are counted?

Rounds announced in the last twelve months with a stated amount and stage, each read from a named article or filing. A page is only published where at least 30 rounds stand behind it.

Are these figures biased?

Towards larger rounds, yes. Big rounds are announced; many small ones never are. So the true typical round is probably a little smaller than the figure here, especially at pre-seed and seed.

How often does it change?

The figures are recounted from the record every night, as new rounds are read.
