Palo Alto Networks, Inc., PANW

Palo Alto Networks CEO Nikesh Arora made a notable open-market stock purchase Friday, snapping up roughly $10 million in company stock after PANW fell sharply on fresh concerns tied to an Anthropic AI model announcement.

Arora bought shares at prices ranging from $146.46 to $147.48 each, according to a filing with the Securities and Exchange Commission. The purchase is being watched closely by investors as a potential signal of management confidence.

He now directly owns 343,394 shares and holds an additional 758,552 shares through two trusts. Combined, those positions were worth about $162 million based on Friday’s closing price.

The stock slid around 6% during the regular session Friday, pulled down by a Fortune magazine report describing an upcoming Anthropic AI model. The model is said to offer cybersecurity-related capabilities of its own, while also featuring advanced functions that could challenge traditional cyber defense tools.

According to the report, Anthropic is providing an early-access version of the model to cyber defenders to help them prepare for its new capabilities before a wider launch.

Why Analysts Think the Selloff Went Too Far

The scale of the drop surprised some on Wall Street. Several analysts pushed back on the idea that Anthropic or other AI model developers represent a direct threat to established cybersecurity vendors.

He added that the rise of offensive AI capabilities should push organizations to strengthen their cyber defenses further, which could actually benefit companies like Palo Alto Networks over time.

Still, jittery software investors have been quick to sell on AI-related news throughout 2026, and PANW has not been immune.

PANW Down 20% in 2026

The cybersecurity sector has had a rough ride this year. PANW has dropped around 20% since January 1, 2026. That compares to a 27% decline in the iShares Expanded Tech-Software ETF (IGV) over the same stretch.

Friday’s session extended losses across the cybersecurity category, with several peer stocks also falling alongside PANW.

Arora’s insider buy came the same day as the selloff. When a senior executive purchases stock on the open market, it is often interpreted by investors as a sign that leadership views the current price as undervalued.

Palo Alto Networks did not immediately respond to a request for comment on the purchase or on Arora’s motivations.

PANW closed Friday near $147, and then gained 1.3% in after-hours trading following disclosure of Arora’s purchase.
