Boujnah argued that joining forces would create a pan-European market infrastructure with planetary scale. While he stopped short of announcing formal negotiations, his comments to the Financial Times suggest a strategic shift for Euronext, which currently operates exchanges across eight countries, including France, Italy, and the Netherlands. Deutsche Boerse, anchored by the Frankfurt stock exchange, remains more cautious, telling the publication that no current conversations exist between the two firms.

Any move toward a merger faces significant regulatory hurdles. European antitrust authorities have a track record of blocking large-scale consolidation in the sector, citing competition concerns. Regulators previously halted a 17 billion dollar merger between the two groups in 2012, and later struck down a proposed 30 billion dollar deal between the London Stock Exchange and Deutsche Boerse in 2017. Despite the regulatory shadow, Euronext shares rose 2.2 percent to 161.70 euros, while Deutsche Boerse climbed 3.3 percent to 285.30 euros.
