During testimony before the House Financial Services Committee on Wednesday, NYSE President Lynn Martin revealed that the exchange participated as an early collaborator in Anthropic’s Project Glasswing program.

According to Martin, the AI-powered technology enabled the exchange to discover several security issues and address them in a timely manner. She did not disclose specific information regarding the nature of these vulnerabilities or the timeline for their resolution.

Understanding Project Glasswing

Anthropic’s Project Glasswing is an exclusive initiative that provides carefully selected organizations with early access to the company’s Mythos AI model. The program is designed to assist participating entities in bolstering their cybersecurity infrastructure.

According to Anthropic, Mythos represents its most advanced model tier. The technology remains restricted to select partners and is not yet available for general use.

Intercontinental Exchange serves as the parent organization of the NYSE and manages additional financial market infrastructure operations worldwide.

Congressional Testimony Context

The revelation emerged when Representative Bill Huizenga, a Michigan Republican, questioned Martin about the exchange’s preparedness for coordinated cyber threats.

Martin referenced the Project Glasswing collaboration to illustrate the exchange’s proactive approach to enhancing its security infrastructure.

Additional details about the severity of discovered vulnerabilities or the resources deployed for remediation were not provided during her testimony.

The NYSE’s involvement in the program places it within an exclusive cohort of institutions granted early access to the Mythos model for defensive security applications.

Cybersecurity concerns have intensified among financial market operators over the past several years. Regulatory bodies and elected officials have increasingly demanded that major exchanges prove their resilience against advanced cyber threats.

With millions of transactions processed daily, the NYSE represents a high-profile target for malicious actors.

Martin’s statements to Congress contained no references to ongoing threats or security breaches. The cybersecurity work she described appears to have been preventative in nature rather than reactive to any incident.

Anthropic has not made public a complete roster of Project Glasswing participants. The NYSE’s participation only became known through Martin’s congressional remarks.

On the day of the testimony, Intercontinental Exchange stock declined 1.39%.

Neither Anthropic nor the NYSE provided additional statements at the time of this report.
