From the WSGR Database: Financing Trends for Q1-Q3 2018 -

Market conditions for venture funding remained very strong in the third quarter of 2018. Deal size and pre-money valuations across all equity rounds decreased slightly but still remained high by historical standards. Median pre-money valuations inched down across the board in Q3 2018. The decline in median amounts raised was more significant, with Series B financings taking the most significant hit, and with the median size falling nearly 50% from the prior quarter. However, more post-Series A financings were up rounds, reversing the decline seen in the first half of 2018.
