Cloudflare Shares Rise Nine Percent Following Strategic Security Partnership With OpenAI

Cloudflare’s second-quarter fiscal 2026 results included $696.1 million in revenue, up 36% year over year, and non-GAAP earnings per share of $0.29, ahead of the $0.27 consensus estimate. The stock’s gain extended its year-to-date advance to 56%.
CEO Matthew Prince described Cloudflare as being at the center of a “fundamental rewrite of the Internet for machine-to-machine traffic,” offering a broader strategic rationale for the company’s AI-infrastructure positioning.
Automated and non-human traffic now accounts for more than half of global network flows, according to one analysis, indicating that security architectures may increasingly need to protect AI agents rather than only conventional human users.
Cloudflare’s AI strategy also includes Adaptive Intelligence and support for Cursor Cloud Agents, products cited as strengthening its role in supporting advanced AI workloads beyond the OpenAI security service.
Institutional interest was linked to increased holdings disclosed by HighTower Advisors and Virginia Retirement Systems, providing specific examples of the large-investor buying that accompanied the rally.
Cloudflare shares jumped about 10% after the company announced a security partnership with OpenAI that uses AI models to find vulnerabilities and patch code automatically. Insider Monkey reported the stock climbed to $10.51 apiece. The rally reflects investor excitement about Cloudflare's role in securing AI infrastructure as machine-to-machine traffic reshapes the internet.
The company's second-quarter results showed revenue of $696.1 million, up 36% year over year, and beat earnings expectations. Cloudflare has now gained 56% year to date, powered by institutional buying and strong demand for AI-focused security tools.
Cloudflare Managed Defense now uses OpenAI's Daybreak cyber models to identify vulnerabilities and detect attacks in real time. Yahoo Finance noted the partnership also generates automated code patches. The integration positions Cloudflare as essential security infrastructure for companies deploying AI agents and autonomous systems.
CEO Matthew Prince framed the move as part of a larger shift. He said Cloudflare sits at the center of a "fundamental rewrite of the Internet for machine-to-machine traffic." Automated and non-human traffic now makes up more than half of global network flows, meaning security must protect AI agents, not just human users.
Cloudflare reported non-GAAP earnings per share of $0.29, ahead of the $0.27 consensus estimate. The beat came as large investors like HighTower Advisors and Virginia Retirement Systems increased their holdings. AOL cited the Meta Muse AI agent launch as part of the broader AI momentum lifting the stock.
The stock's 56% year-to-date gain reflects sustained appetite for AI infrastructure plays. Other cybersecurity firms like Zscaler gained modestly on their own OpenAI connections, but the rally was largely specific to Cloudflare.
Cloudflare remains unprofitable on a GAAP basis and carries heavy infrastructure spending tied to edge computing and Zero Trust security products. Motley Fool noted the stock can swing sharply if AI demand weakens or market conditions tighten. Leverage and cash burn also leave room for disappointment if growth slows.
CEO Prince also highlighted products like Adaptive Intelligence and Cursor Cloud Agents support as pillars of the AI strategy. These tools aim to strengthen Cloudflare's foothold in advanced AI workloads beyond just cybersecurity.
