The New York Stock Exchange has deployed artificial intelligence technology from Anthropic to identify and remediate security weaknesses within its infrastructure.
During testimony before the House Financial Services Committee on Wednesday, NYSE President Lynn Martin revealed that the exchange participated as an early partner in Anthropic’s Project Glasswing initiative.
According to Martin, the AI-powered technology enabled the exchange to discover several security issues and address them promptly. She declined to elaborate on the specific nature of the vulnerabilities or provide a timeline for when the remediation occurred.
Understanding Project Glasswing
Anthropic’s Project Glasswing represents a specialized initiative that grants exclusive access to the company’s Mythos AI model to a carefully selected group of organizations. The primary objective is to enable these partners to enhance their cybersecurity posture.
According to Anthropic, Mythos represents its highest-capability model tier. Currently, the technology remains unavailable to general users and is restricted to approved participants.
The NYSE operates under Intercontinental Exchange, its parent organization, which manages various financial market infrastructure systems worldwide.
Congressional Context
Martin’s revelation emerged during a line of questioning from Michigan Republican Representative Bill Huizenga. The congressman inquired about the exchange’s preparedness protocols for defending against organized cyberattacks.
Martin cited the Project Glasswing participation as a concrete example demonstrating the exchange’s proactive approach to bolstering its security infrastructure.
The NYSE president offered no additional information regarding the severity of the discovered vulnerabilities or the investment required to address them.
By participating in the program, the exchange joins an exclusive cohort of institutions granted early access to the Mythos model for defensive security applications.
Financial market infrastructure operators face mounting cybersecurity challenges. Regulatory bodies and legislative officials increasingly demand that major exchanges prove their ability to resist advanced cyber threats.
As a platform handling millions of transactions daily, the NYSE represents a particularly attractive target for malicious cyber actors.
Martin’s remarks to Congress made no reference to ongoing threats or security breaches. The cybersecurity work she described appears to have been conducted as preventive testing rather than incident response.
Anthropic has not released a public roster of Project Glasswing participants. The NYSE’s involvement only became known through Martin’s congressional appearance.
Shares of Intercontinental Exchange declined 1.39% on the day Martin delivered her testimony.
Neither Anthropic nor the NYSE provided additional statements at press time.
