Financial centres around the globe, including New York, London and Tokyo, have been making a special effort to win the oil giant's $100 billion (82.1 billion pounds) listing, which is expected to be the largest IPO ever.

Nasdaq is already the technology provider to Saudi Arabia's exchange, and will use that relationship to promote the idea of a dual listing in Riyadh and another global market, Nasdaq CEO Adena Friedman said. Nasdaq is based in New York, where its exchange operates, but offers technology services to other global exchanges.

"Every exchange in the world right now is competing to be considered as an exchange for the Aramco listing, including us," Friedman said in an interview at the FIA's International Futures Industry Conference on Tuesday. "We're very active in finding opportunities to work with the Aramco team and demonstrate that we are the natural place for them."

Saudi authorities plan to list up to 5 percent of the world's largest oil producer on the Saudi stock exchange in Riyadh, the Tadawul, and also one or more international markets. Exchanges also vying for the listing include markets in Hong Kong, Japan, Singapore and Toronto.
