What Happened?
Tenable (TENB) stock dropped 8% on Friday as cybersecurity stocks sold off sharply following a report that Anthropic is testing a powerful new AI model with advanced cyber capabilities — and significant security risks to match.
Fortune first reported the news, citing a publicly accessible draft blog post from Anthropic.
- The new model, called Mythos, is being described as the company’s most powerful yet.
- Anthropic is reportedly planning a slow rollout specifically because of concerns about what it could enable in the wrong hands.
The selloff hit the entire sector hard.
- The iShares Cybersecurity ETF fell 4.5%.
- CrowdStrike, Palo Alto Networks, and Zscaler each dropped around 6%.
- SentinelOne tumbled 6%, while Okta and Netskope fell more than 7%.
- Tenable stock took the biggest hit of the group, falling 8%.
This isn’t the first time AI headlines have rattled cybersecurity names.
Last month, stocks in the sector fell after Anthropic added a code-scanning security tool to Claude.
The fear is consistent: if AI makes hacking easier and more automated, the threat landscape changes faster than security vendors can respond.
Anthropic itself flagged this risk back in November, disclosing that a state-sponsored Chinese group had used Claude to help automate a cyberattack.

What the Market Is Telling Us About Tenable Stock
The reaction is driven more by disruption fears than by fundamentals.
Tenable stock’s underlying business actually looks solid.
- In Q4 2025, the company beat all guided metrics, grew revenue 11% year-over-year, and hit a record with 46% of new business coming from its Tenable One exposure management platform.
- Management is guiding for revenue to exceed $1 billion in 2026 for the first time.
The irony is that Tenable is actively building AI into its platform to help customers detect exactly these kinds of threats.
The company closed its first seven-figure AI security deal last quarter and is seeing growing demand from CISOs worried about AI-driven attacks.
But the market isn’t focused on that today.
When a new AI model threatens to make cyberattacks cheaper and easier, investors sell first and ask questions later.
Until the sector proves it can stay ahead of AI-powered threats, Tenable stock and its peers may stay volatile on days like this.
