According to a 2018 New York Times report, over half of all companies listed on the New York Stock Exchange (NYSE) are incorporated in Delaware. The state's business-friendly laws, specialized Court of Chancery, and predictable legal framework make it the premier jurisdiction for corporate formation.
Because listings change daily through IPOs, mergers, and delistings, the exact number fluctuates. For the most current figure, consult the NYSE's official directory or a financial data provider like Bloomberg or FactSet.
