This is a list of major stock exchange mergers and acquisitions in the Americas. It also features the name of any resultant stock exchanges from mergers or acquisitions. According to Robert E. Wright of Bloomberg in 2013, historians assert that "rather than exhibiting a trend of constant consolidation, the number of exchanges active across the globe has waxed and waned several times over the past 200 years... During periods of heightened regulation, political turmoil or communication advances, exchanges tend to fail or merge. Economic prosperity, increased financial speculation and high levels of market uncertainty, by contrast, drive new entries."
