The development was disclosed by NYSE President Lynn Martin during testimony before a U.S. congressional committee on Wednesday.

AI for Cyber Defense

Speaking to the House Financial Services Committee, Martin revealed that the NYSE participated as an early partner in Anthropic's Project Glasswing. This initiative provides select, vetted partners with early access to Anthropic's Mythos AI model specifically to strengthen their cyber defenses.

Martin stated that the technology enabled the exchange to locate multiple security issues. She added that the exchange was able to resolve the identified vulnerabilities quickly, though she did not provide specific details on the nature of the flaws or the exact timeline for their remediation.
