Duncan Niederauer is a long-time securities industry executive, having spent his career at Goldman Sachs and NYSE Euronext. He retired as CEO from the NYSE in August 2014 after it was bought by the Intercontinental Exchange.  After the takeover he became president of NYSE Euronext and stayed in that role from November 2013 to May 22, 2014.
In October 2014 he joined an "upstart" brokerage firm called Battery East in a part-time role as a managing director. Battery East opened in 2013 with the aim of helping employees of privately held companies cash out of their shares through secondary sales.
In November of 2018, Niederauer became an advisory board member of the Association for Digital Asset Markets (ADAM), a group formed by ten financial services and technology firms to be the first broad-based organization in the United States to proactively seek comprehensive standards for digital asset market participants.
Niederauer also served as a member of the NYSE Euronext's management committee and on the boards of NYSE Group and Euronext, as well as on the board of directors of the World Federation of Exchanges.
Niederauer was hired in 2007 to try to revitalize the Big Board, which had been struggling since its peak in the 1990s. His solution has been to deliver on cost-cutting promised by his predecessor in the 2007 merger with Euronext, while investing in the company's technology and diversifying its business lines. He was an outspoken proponent of electronic trading and continued NYSE's move into computerized market making of stocks.
On March 3, 2010, NYSE Euronext said Niederauer would focus his attention on the exchange operator's derivatives business, seeing it as the key driver of revenue growth in coming years. To that end, he entered into negotiations with Deutsche Borse on a merger of the two companies which would create the world's largest exchange, with significant operations in stocks, options and other derivatives. Deutsche Boerse is a big player in European futures contracts, one of the most profitable businesses for NYSE Euronext. 
In a speech given at a Futures Industry Association (FIA) luncheon in July of 2008, Niederauer provided some insight into his management style. "It's OK to try some things that don't work," he said, explaining that he'd rather his employees were innovative rather than fearful of failure. He also insisted that he's open to giving people a "free pass" if a new idea fails.
In April 2011, a bidding war erupted between Deutsche Boerse and the combination of Nasdaq OMX and ICE over the merger with NYSE Euronext. Nasdaq OMX and ICE withdrew their offer in May 2011  after the U.S. Justice Department indicated it would not approve it. 
Before taking the reins as CEO of the exchange, Niederauer joined NYSE Euronext as president and co-chief operating officer in April 2007. He was previously a partner at The Goldman Sachs Group, Inc. (U.S.), where he held many positions, including co-head of the Equities Division Execution Services franchise and the managing director responsible for Goldman Sachs Execution & Clearing, L.P. (formerly known as Spear, Leeds & Kellogg L.P.). He joined Goldman in 1985. From March 2002 until February 2004, he also served on the board of managers of Archipelago Holdings, LLC. 
Niederaurer participated in the MarketsWiki Education World of Opportunity series in New York in July of 2017 at Thomson Reuters.
Niederauer received a B.A. from Colgate University and an MBA from Emory University.
