The cybersecurity sector faced significant volatility as news of an advanced AI model from Anthropic, reportedly named "Mythos," sparked fears of competition against established security vendors. This led to a sharp sell-off in key stocks, most notably Palo Alto Networks (PANW), which fell roughly 6% during regular trading on Friday, March 30, 2026.
In a move interpreted as a vote of confidence, Palo Alto Networks CEO Nikesh Arora purchased approximately $10 million worth of PANW stock at prices between $146.46 and $147.48 per share. Following this disclosure, the stock rose 1.3% in after-hours trading. Arora now holds a combined position worth about $162 million across direct ownership and trusts.
Analysts quickly pushed back against the narrative of direct competition. Piper Sandler analyst Rob Owens noted that Anthropic's move to provide an early-access version to cyber defenders "clearly signals its desire to partner rather than compete with security vendors." He argued that the rise of offensive AI capabilities should actually drive organizations to strengthen defenses, benefiting companies like Palo Alto Networks.
Separately, CrowdStrike Holdings Inc. received an analyst upgrade that fueled a 4.6% gain. Wolfe Research upgraded the stock to "outperform," setting a price target of $450, implying about 21.8% upside. Analyst Alex Zukin reinforced the bullish case, stating that the prospect of a "machine-speed" cyberwar driven by AI will likely force companies to increase cybersecurity spending, not reduce it, benefiting established platforms like CrowdStrike.
The sector has struggled in 2026, with PANW down around 20% year-to-date, underperforming the broader iShares Expanded Tech-Software ETF (IGV), which is down 27% over the same period.
