SAN FRANCISCO -- It's looking more and more like the New York Stock Exchange will win the Tweetstakes, the hotly contested battle with the Nasdaq Stock Market for Twitter's initial public stock offering. Twitter is the most highly sought after technology listing since Facebook and the exchanges are aggressively jockeying for Twitter's business. A person familiar with the situation denied a report Tuesday that Twitter had already selected the NYSE over Nasdaq. A final decision has not yet been made, said the person who spoke on the condition of anonymity because he was not authorized to speak publicly about the matter. The NYSE and Nasdaq declined to comment. Twitter also declined to comment. Twitter filed confidentially for its IPO. It announced to the world it was going public in a tweet Sept. Nasdaq used to rule the roost for technology listings, but the NYSE has proved a formidable competitor in recent years. After technical glitches marred Facebook's debut, Nasdaq lost some of its luster. Nasdaq had to pay out $10 million to the U.S. Securities and Exchange Commission to settle charges. It also set up a $62-million fund to pay back firms that had losses. The Nasdaq also suffered an embarrassing glitch in August that shut down trading for three hours. The prestige of landing the high-flying Twitter would be an opportunity for Nasdaq to redeem itself after Facebook. It would also be a major coup for the NYSE, which has established itself as a contender for technology listings after having won over LinkedIn, Pandora and Workday, among others. So far this year, according to Nasdaq data, the exchange is tied with the NYSE for 16 tech IPOs each.
