The landscape of artificial intelligence is shifting at a breathtaking pace, and Anthropic is right at the centre of the storm. In a series of ground-breaking developments, the tech heavyweight has officially set its sights on the stock market whilst simultaneously expanding access to its most powerful, and highly scrutinised, AI model to date: Claude Mythos.
Coming just twenty-four hours after the company announced its plans for an Initial Public Offering (IPO), this strategic expansion highlights a fascinating tension in the AI industry—the race to commercialise frontier technology balanced against the critical need for global cybersecurity safeguards.
Anthropic has taken its first definitive step toward becoming a publicly traded company. The developer confidentially submitted a draft S-1 registration statement to the U.S. Securities and Exchange Commission (SEC), paving the way for a highly anticipated floating on the stock market.
This move comes on the heels of reports valuation figures for the AI giant are nearing an astonishing $1 trillion. While the final timing and scale of the IPO remain subject to market conditions and regulatory approval, the announcement signals that Anthropic is ready to mature from a heavily backed startup into an institutional market leader.
However, launching a public offering requires proving to investors that its most advanced models are not just revolutionary, but safe and legally viable. Enter Project Glasswing.
To ensure its flagship technology is robust enough for a wider release, Anthropic is expanding Project Glasswing. This controlled initiative allows elite technology companies, cybersecurity firms, and government bodies to stress-test the Claude Mythos model, hunting down vulnerabilities and creating software patches before the system is rolled out to the general public.
Anthropic announced that it is adding approximately 150 new organisations to this restricted program. Crucially, these new partners are being pulled from critical infrastructure sectors, including:
The stakes could not be higher. Many of these organisations maintain the core infrastructure and software utilised by governments and hundreds of millions of citizens worldwide. Anthropic openly acknowledged the gravity of the project, stating that a successful cyberattack on the codebases of these partners could be catastrophic, impacting global and national security.
Claude Mythos first caught the public's attention in March 2026 after internal draft materials leaked online. Since then, early testers using Mythos Preview have successfully identified more than 10,000 high- or critical-severity software flaws, demonstrating its immense value to digital defenders. For example, Mozilla utilised the model to find and patch 271 bugs within the Firefox browser.
Yet, the sheer capability of Mythos has raised serious alarm bells among global security researchers. The model possesses an unprecedented aptitude for executing complex cyber operations. During rigorous testing, the U.K. AI Security Institute revealed that Claude Mythos managed to autonomously complete a 32-step simulated corporate network attack. Furthermore, security startup Calif noted that an early version of the model assisted researchers in mapping out an exploit chain targeting Apple’s advanced M5 computer chips.
This creates a classic dual-use dilemma. The same intelligence required to fix a bug can also be weaponised to exploit it.
Anthropic’s philosophy, however, is one of proactive defence. The firm believes that defenders must be equipped with cutting-edge AI tools before malicious actors inevitably build or acquire similar capabilities. With predictions that rival developers will launch equivalent "Mythos-class" models within the next six to twelve months—potentially without rigorous safety guardrails—Anthropic is racing to secure a permanent advantage for the cybersecurity industry.
While Anthropic previously hinted that a broader release of Mythos-class models to standard enterprise customers could happen "in the coming weeks," the timeline remains fluid. The company is actively refining safety protocols to mitigate the risks highlighted by government agencies.
This abundance of caution has caused a shift in public expectations. On Myriad, a popular prediction market platform, user confidence that Claude Mythos will see a full public launch by the end of June has dropped sharply to just 26.5%, down from a high of nearly 59% the previous week.
For now, Anthropic is balancing on a tightrope: satisfying the rigorous safety demands of national governments whilst preparing for one of the biggest tech IPOs in history.
