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).

The median is $50M, from 427 Series B rounds announced worldwide in the last twelve months. Half of them raised between $30M and $100M; one in ten raised more than $200M. 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.
