Anthropic is expected to release the public version of its powerful Mythos AI model under the name Claude Fable, with the launch date appearing to be June 9 or 10, 2026, according to a report from The Information.
The release brings advanced cybersecurity capabilities into broader access, creating both opportunities and urgent risks for the crypto sector.
Mythos preview and what it can do
Anthropic first introduced Claude Mythos Preview in April 2026 through Project Glasswing, a restricted program involving partners like AWS, Microsoft, Apple, and CrowdStrike.
The model demonstrated exceptional ability to autonomously discover and chain zero-day exploits across major operating systems and browsers.
Polymarket assigned a high probability to a June 9 debut, with developer tool leaks and backend sightings fueling intense speculation ahead of the launch.
The crypto security threat
Blockchain projects, exchanges, and wallet providers now face an AI that can rapidly identify subtle vulnerabilities in smart contracts, node software, and infrastructure.
This compresses exploit timelines dramatically, raising stakes in a market already sensitive to security incidents.
Altcoins and smaller projects with less rigorous auditing practices could be particularly exposed, as the model lowers the barrier for attackers to find and chain exploits at scale.
On the defensive side, Mythos-class tools promise faster audits and patching, and crypto firms adopting AI-driven security could gain a meaningful edge.
Pricing and who gets access
Access is expected to cost roughly double current Claude Opus tiers, targeting institutional and security-focused users rather than casual users.
Analyst Bull Theory noted:
“Claude Fable will be roughly twice as expensive as today’s most advanced Claude Opus models. The original Mythos pricing shared in April was five times higher than Opus. The public version is cheaper, but still double anything available today.”
Anthropic’s recent $65 billion funding round and confidential IPO filing underline its premium positioning in critical infrastructure.
What investors should watch
If the full rollout proceeds as expected, broader availability could follow in the coming weeks, with expanded Project Glasswing participation potentially including crypto-native organizations.
Investors should prioritize projects with robust AI-assisted security, frequent audits, and proactive vulnerability management as this new threat landscape takes shape.
