Fortinet (FTNT) stock reached an all-time high of $176.23 on Wednesday, extending one of the strongest rallies in cybersecurity this year. FTNT was trading around $174.73, up about 0.3%, after briefly touching the new record.

Fortinet, Inc., FTNT

The stock has gained about 119% in 2026 and more than doubled over the past year. The move has been supported by faster revenue growth, strong billings and rising demand for security products tied to AI infrastructure.

Fortinet’s latest quarterly results helped strengthen that momentum. Second-quarter revenue rose 26% year over year to $2.05 billion, while billings climbed 33% to $2.37 billion.

AI Security Demand Supports Growth

Product revenue increased 52% to $773 million during the quarter. Fortinet said stronger FortiGate unit sales and higher average selling prices contributed to the increase.

Management also said customers are spending more to protect AI workloads and manage AI-related security risks. That demand supported growth across hardware, software and attached services.

Fortinet’s non-GAAP operating margin reached 38%, while free cash flow climbed to $966 million. Operating cash flow came in at $1.04 billion.

The company raised its full-year outlook following the quarter. Fortinet now expects 2026 revenue of $8.02 billion to $8.18 billion and billings of $9.35 billion to $9.55 billion.

Fortinet has also been expanding its AI security portfolio. In August, it acquired Virtue AI, a company focused on AI runtime protection, automated validation and security for autonomous AI systems.

The acquisition builds on Fortinet’s existing FortiAIGate offering, which is designed to protect large language models and AI applications from threats such as prompt injection, data leakage and model abuse.

Valuation Becomes the Bigger Question

The strong operating results have pushed expectations much higher. Fortinet’s rally has also taken the stock above or close to several analyst price targets.

TD Cowen recently reiterated a Buy rating with a $215 target, while Stifel maintained a Hold rating with a $175 target. Bernstein has a Hold rating and $145 target, showing that Wall Street remains divided on how much upside is left.

That disagreement reflects the main investor risk after such a rapid rise. Fortinet still needs to sustain high growth in billings, product revenue and AI-related security spending to support its higher valuation.

Competition is another factor, with Fortinet operating against large cybersecurity rivals across network security, cloud security and AI protection. Any slowdown in enterprise spending or weaker-than-expected execution could pressure the stock after its strong run.

For now, the market continues to reward Fortinet’s accelerating growth. Wednesday’s move to a record $176.23 follows a quarter in which revenue rose 26%, product revenue increased 52% and management raised its full-year guidance.
