Palo Alto Networks today [announced](https://www.paloaltonetworks.com/company/press/2025/palo-alto-networks-to-acquire-chronosphere--next-gen-observability-leader--for-the-ai-era?ref=theleftshift.com) a definitive agreement to acquire Chronosphere, a next-generation observability platform engineered for modern AI workloads, for $3.35 billion in cash and replacement equity awards.

The deal is expected to close in the second half of Palo Alto Networks’ fiscal 2026, subject to customary regulatory approvals.

 *“The foundational requirement for every modern AI data center is constant uptime and resilience, which demands real-time, always-on observability delivered at the right cost. Chronosphere was built to scale for the data demands of the AI era from day one … once we leverage AgentiX with Chronosphere, we will take observability from simple dashboards to real-time, agentic remediation,” Palo Alto CEO* [*Nikesh Arora*](https://www.linkedin.com/in/nikesh-arora-02894670/?ref=theleftshift.com) *said.*

By combining Chronosphere’s optimized data-ingestion architecture with its Cortex AgentiX AI-agent platform, Palo Alto aims to enable autonomous IT remediation—letting agents not only detect performance problems but also investigate root causes and self-heal.

 *“We founded Chronosphere to provide scalable resiliency for the world’s largest digital organisations. Palo Alto Networks is the perfect strategic partner … accelerating our momentum in solving the most complex data and resiliency challenges,”* [*Martin Mao*](https://www.linkedin.com/in/martinmao/?ref=theleftshift.com)*, co-founder and CEO of Chronosphere, added.* 

As of the end of September 2025, Chronosphere reported annual recurring revenue (ARR) of over $160 million, fueled by triple-digit year-over-year growth. 

Positioned as an “always-on” observability solution built for the scale of AI, Chronosphere was recognised as a Leader in the 2025 Gartner Magic Quadrant for Observability Platforms. 

Once the acquisition closes, the integrated observability-security solution will provide customers with deeper visibility across security and performance data at petabyte scale, while delivering better cost-efficiency at large scale.
