CrowdStrike and Palo Alto Networks hit record highs on Monday. Each rose more than 5%, after a week in which the Black Hat conference in Las Vegas turned into an argument about AI agents.

CNBC’s Samantha Subin reported the move. CrowdStrike gained 11.32 points, or 5.28%. Palo Alto added 17.84 points, or 4.90%, and traded at $381.70 in the afternoon.

The rest of the sector followed. Tenable and Rubrik rose more than 7%. Netskope and Zscaler each gained about 5%.

A price target overtaken the same day

BTIG lifted its price target on Palo Alto to $380 on Monday. The firm called that about 4% upside from Friday’s close.

The stock passed it within hours. Palo Alto changed hands at $381.70 that afternoon, above a target raised the same morning. Buyers are repricing this sector faster than the analysts who cover it.

CrowdStrike’s target went to $237, which BTIG put at 11% upside from Friday. Rubrik went to $109. None of the three revisions followed an earnings release.

What changed at Black Hat

BTIG’s analysts spent the conference talking to partners, vendors and customers. The consistent theme, they wrote, was that AI agents “have fundamentally changed the threat landscape.”

They called the environment meaningfully worse than before. They also said the deployment of AI security tools sits “only in the early innings”.

Cantor’s analysts reached a similar view. AI has moved “from being a cybersecurity feature to a key pillar” of both the attack surface and the infrastructure on either side of it, they wrote.

The trade has a name on television too. Jefferies analyst Joseph Gallo argued last week that cyber spending will benefit from AI anxiety over the next couple of quarters.

The week supplied its own evidence

Black Hat did not lack for demonstrations. Researchers used the conference to pick apart a Hugging Face breach carried out by an AI agent rather than a person.

The pattern is no longer theoretical. Security firms have already documented an end-to-end ransomware attack run by an agent from reconnaissance through to extortion.

Private money is moving on the same thesis. Mate Security raised $50m for AI-driven security operations during the same conference week.

What Monday does not prove

This was one trading session on sell-side commentary. Neither company reported results, and no customer contract was announced. Analyst notes move stocks, but they are not revenue.

There is a circularity worth naming. The companies whose shares rose are the ones selling the fix for the threat their own conference describes, and BTIG says that build-out has barely started.

Spending is also not the same as safety. Buying more tools has never closed the remediation gap between finding a problem and fixing it.

Palo Alto has its own unfinished argument here. Its chief executive Nikesh Arora has said AI token pricing must fall before the economics of agentic security work at scale.

The test arrives with results. Targets can be raised again, and often are, but the claim that AI has changed the threat landscape only pays off if customers spend against it. Until then, Monday’s records rest on a week of conversations in Las Vegas.
