CrowdStrike stock slides after Anthropic’s Claude security debut; Telefónica deal and March 3 earnings loom

NEW YORK, Feb 22, 2026, 12:32 ET — Market closed.

CrowdStrike Holdings (CRWD) finished Friday’s session down 7.95% at $388.60, slipping from an intraday peak of $431.88 and hitting a low of $387.11. U.S. markets remain closed until Monday, leaving investors waiting to see how the stock responds after Friday’s sharp decline.

Cybersecurity stocks took a hit after Anthropic introduced its “Claude Code Security” code-scanning tool, spooking investors with the prospect that AI-driven products might eat into the traditional security software market. Cloudflare and Okta shares dropped hard along with the rest. Investing

Why now: CrowdStrike’s fourth-quarter and full-year fiscal 2026 numbers hit after the bell on Tuesday, March 3, with a conference call on deck later that day. Traders aren’t just eyeing demand signals this time—they’re watching for any sign that AI platform contenders are making legitimate inroads in parts of the security sector.

Friday brought a round of company updates, too. Telefónica Tech is deepening its alliance with CrowdStrike, announcing plans to integrate CrowdStrike Falcon Next-Gen SIEM into Telefónica’s NextDefense XDR managed security lineup. SIEM collects and parses security data; XDR ties together signals from different systems for faster responses. “The speed, automation, and intelligence they need to stay ahead of modern attacks”—that’s how Daniel Bernard, CrowdStrike’s chief business officer, described the package.

Anthropic said Claude Code Security, now in limited research preview for Enterprise and Team customers, is built to scan codebases for vulnerabilities and recommend patches for human review. According to the company, its models surfaced over 500 vulnerabilities in live open-source codebases during internal tests.

On Wall Street, a few voices pushed back, saying the market had jumped the gun. Barclays went so far as to label the selloff “incongruent,” adding it doesn’t see the tool as a threat to its covered firms such as CrowdStrike. TipRanks

The decline was notable, given that the broader market pushed higher. The S&P 500 ticked up 0.69% on Friday, session data show. Fortinet dropped roughly 2%, with Palo Alto Networks down around 1.5%.

CrowdStrike offers subscription-based software aimed at detecting and blocking threats across devices, cloud infrastructure, and identities. The stock tends to move with investor expectations for customers to pick up additional modules, and on the willingness of larger enterprises to roll more of their security budgets into a single platform.

CrowdStrike’s latest quarterly filing showed annual recurring revenue (ARR) up 23% from a year earlier, hitting $4.92 billion on Oct. 31, 2025. Total revenue climbed 22% to $1.23 billion.

Friday’s almost 8% drop underscored that. In high-growth software, sentiment doesn’t need much to turn—downside scenarios get traction fast, particularly once “AI disruption” grabs the spotlight for the week.

Come Monday, traders are eyeing whether the sector finds its footing or slips further, and also how analysts position Anthropic’s launch: actual spending risk, or just noise? Company remarks clarifying which budgets Claude Code Security could impact may end up carrying more weight than whatever plays out on the macro tape that day.

CrowdStrike’s next clear catalyst lands March 3, with results due out after the bell. That should finally give management a shot at responding directly to the latest AI-competition buzz and updating its outlook.
