List of US ETF providers

 is alphabetical, but can be sorted according to year of entry into the marketplace or by Assets Under Management (AUM). The table contains, where available, links to each provider's website, as well as links to a provider's ETF database page. These links provide information regarding each provider's range of offerings, expense ratios, and access to factsheets, prospectuses, annual reports and additional information.

Since the first issuance of an exchange-traded fund (the SPYDER S&P 500 ETF) on the American Stock Exchange in 1993, there has been steady growth in the number of firms providing ETFs in the U.S. market. At year end 2011, ETF's in the U.S. totaled 1066 funds holding 1.048 trillion dollars in net assets.

The ETF marketplace is quite active, with new firms frequently entering and leaving (through acquisition, merger or liquidation) the marketplace. In terms of net assets under management, the U.S. marketplace is dominated by the large ETF providers (Blackrock, State Street, and Vanguard). Some providers specialize in offering exchange-traded notes (ETNs) or funds-- primarily those specializing in commodities or currencies-- that are held in master limited partnerships (LP). These forms of organization possess additional risks to the potential shareholder (credit risk with ETNs and tax complications with LPs). Firms specializing in these instruments are footnoted.
