The CNBC Crowdfinance 50 Index

To get a pulse reading on the emerging equity crowdfunding market, take a look at the CNBC Crowdfinance Index. It is the daily average index of the 50 largest capital commitments by private U.S. companies listed on Crowdnetic's data platform, which collates real-time offerings from 18 securities-based crowdfunding sites: Alchemy Global, AngelList, Crowdfunder, CrowdStreet, EarlyShares, EquityNet, MicroVentures, Onevest, OurCrowd, Patch of Land, Prodigy Network, RealCrowd, RealPartner, Realty Mogul, DarcMatter, SeedInvest and WeFunder.

Companies represented on the index are operating companies raising money, not equity funds. They represent eight sectors: commerce and industry; consumer goods; energy; finance; health care; materials; services and technology.
