Her appointment means that the two major stock exchanges in the US will now be run by women. Adena Friedman has been in charge of NASDAQ, the technology-focused market, since January last year.
Cunningham, who is currently NYSE Group’s chief operating officer, will take over from current incumbent Thomas Farley on Friday.
She began her career in 1996 on the NYSE trading floor as a specialist for Bank of America Securities, before moving to NASDAQ where she worked in a number of senior roles.
She joined NYSE in 2012 as head of sales and relationship management, and was responsible for managing the sales team for US cash equities and options markets. By 2014 she was president of governance services, which provides governance, compliance, and education solutions for companies and their boards. She became COO of the NYSE Group in June 2014.
As COO, she has not only overseen the group’s equities, equities derivatives and exchange-traded products businesses, but she has had responsibility for the product management, sales, and strategy of NYSE’s three equity markets and two options markets.
