Investors are valuing seed-stage startups at the highest levels ever, according to a new report published by the private deals database Pitchbook. According to its analysis, the pre-money valuation for a seed-stage company reached $5.9 million in the first half of this year, an 11 percent increase from the end of 2015 and a whopping 84 percent increase from 2010 figures. At the same time, the median seed round size increased 50 percent year-over-year to $1.5 million, up from $480,000 recorded in 2010.

So whats up?Pitchbook has its theories. It points to the wave of dedicated seed-stage firms to emerge on the scene in recent years, right alongside a growing number of accelerators, the most famous of which remain Techstars, Y Combinator and 500 Startups. (You may not be surprised to learn that there areroughly160 accelerators now up and running in the U.S. alone, according to biz school professors Yael Hochbergof Rice University and Susan Cohenof the University of Richmond, whove taken up the daunting task of starting to rank them every year.)

Pitchbookalso notes that while valuations are up, the number of seed-stage companies getting funded is down, suggesting that those companies that do attract funding have better businesses than some of the startups that raisedseed funding in recent years.

Perhaps more surprising about Pitchbooks newest report on valuations is its conclusion thatvaluation levels for later-stage companies are also at their highest levels on record. According to its findings, the median Series C valuation in the first half of 2016 reached$90 million, which is16percent higher than it was in the first half of 2015. The medianSeries D valuation is similarly higher:13percentyear-over-year to $200 million.

What about the narrative that the down rounds are on the rise, particularly as mutual and hedge funds and other non-traditional sources of venture capital retrench from the market? Pitchbook suggests there has been a considerable decline in Series D activity, but that valuations for the perceived winners mostly just keep increasing.

In fact, it saysthe number of down rounds in the first half of this year are up just 1 percent over the number of completed deals by this time last year. In addition, it says a whopping 76 percent of venture financings have involved a higher valuation than the companys previous round.

The optimist in us wants to proffer thatthese statistics suggest a so-called flight to quality. Just aslikely: Despite feeling moretrepidatious thanin recent years, thosewith capital arent sure where else to invest it right now. Pitchbook estimates there was $95 million in dry powder available to VCs as of the end of 2015. Meanwhile, the first quarter of this yearwhen 67 U.S. venture firms raised more than $14 billion ranked as the strongest quarter for dollars raised since the second quarter of 2006, when 79 funds raised $14.3 billion.
