Cloudflare Statistics 2026: Network Size, Market Share, and Revenue

Cloudflare proxies 23.4% of all websites and 83.5% of all sites with a known reverse proxy. The figures come from W3Techs’s June 2026 site survey. The San Francisco company sits in front of more of the public web than any other vendor, runs a network spanning 337 cities across 8 regions and 100+ countries, and pulled in $639.8 million in Q1 2026 revenue alone. A customer cohort mix shift: large customers ($100,000+ ARR) now drive 73% of Cloudflare’s total revenue (up from 63% in 2022), a quieter signal than headline growth.

The numbers below cover Cloudflare’s network footprint, revenue, and paying customer cohorts, DDoS and threat mitigation telemetry, the new pay-per-crawl economics for AI crawler traffic, and workforce data through Q1 2026. Every figure traces to a primary-source disclosure: Cloudflare press releases, the company’s network page, W3Techs, and the inaugural Cloudflare Threat Report.

Cloudflare Web Traffic and Market Share

• Cloudflare is used by 23.4% of all websites tracked by W3Techs, making it the single largest reverse-proxy vendor by a wide margin.
• Inside the reverse-proxy category specifically, Cloudflare’s share is 83.5% of sites whose reverse proxy is identifiable.
• Wikipedia’s January 2026 snapshot, citing W3Techs, recorded approximately 21.3% of all websites on the Internet running Cloudflare, illustrating roughly two percentage points of share gain in five months.
• The company services roughly 20% of all global internet traffic in terms of visibility, a figure Cloudflare uses to anchor its 2026 Threat Report sample frame.
• Cloudflare’s reach extends across streaming, commerce, and SaaS, with paid services delivered to 162,086 customers at the end of Q4 2022 before doubling to the 2025 cohort below.
• The gap between Cloudflare’s 23.4% site share and its near-monopoly inside the reverse-proxy category points to remaining headroom: every site that adopts any proxy in the future is a likely Cloudflare prospect.

By the numbers: Per W3Techs’s June 2026 survey, Cloudflare serves 23.4% of all websites and 83.5% of those running any identifiable reverse proxy, while Cloudflare’s own 2026 Threat Report says the network has visibility into roughly 20% of global internet traffic. That asymmetry frames the remaining addressable market.

Recent Developments

• June 18, 2026: Pay Per Crawl launch. Cloudflare moved its Pay Per Crawl feature into private beta on June 18, 2026, giving publishers an HTTP 402-based mechanism to charge AI crawlers per request. Publishers are now sending more than one billion HTTP 402 Payment Required responses to AI crawlers every day across the Cloudflare network.
• April 2026: Agents Week. Cloudflare used Agents Week 2026 to consolidate the AI Crawl Control surface across every plan tier, following the August 2025 general availability of AI Crawl Control.
• March 3, 2026, Inaugural Threat Report. Cloudflare published its first Threat Report on March 3, 2026, reporting that 94% of login attempts on protected sites originate from bots rather than humans.
• February 19, 2026: Stack Overflow partnership. Stack Overflow published a joint case study with Cloudflare on February 19, 2026, adopting the Pay Per Crawl model to monetize crawler access to its developer Q&A archive.
• February 2026: FY2025 results. Cloudflare reported full-year 2025 revenue of $2,167.9 million, up 30% year-over-year, and issued FY2026 guidance of $2,785.0 to $2,795.0 million.
• December 2025: Record DDoS event. A single botnet pushed 31.4 terabits per second of traffic in December 2025, the largest publicly disclosed DDoS attack on record.

Cloudflare Revenue and Financial Performance

• Q1 2026 revenue reached $639.8 million, representing an increase of 34% year-over-year.
• Full-year 2025 total revenue came in at $2,167.9 million, up 30% year-over-year, with Q4 2025 alone delivering $614.5 million.
• FY2026 guidance ranges from $2,785.0 to $2,795.0 million in revenue and $378.0 to $382.0 million in non-GAAP operating income.
• Q1 2026 GAAP gross margin was 71.2%, down from 75.9% in Q1 2025 as the company invested in compute capacity.
• Non-GAAP operating margin held at 11.4% in Q1 2026, versus 11.7% in Q1 2025.
• Q1 2026 free cash flow was $84.1 million, or 13% of revenue, up from $52.9 million, or 11% in Q1 2025.

Key finding: Cloudflare’s GAAP gross margin compressed by 4.7 percentage points between Q1 2025 and Q1 2026 (from 75.9% to 71.2%), even as revenue grew 34%. Per the Q1 2026 IR press release, the company continued investing in compute capacity for AI workloads, which carries a different cost profile than traditional CDN traffic.

• Cloudflare ended 2025 with 332,466 paying customers, up 40% year-over-year.
• Large customers (those spending over $100,000 in annualized revenue) totaled 4,298 at the end of Q4 2025, representing 23% year-over-year growth.
• That large-customer cohort drove 73% of total revenue, up from 63% in 2022.
• Cloudflare closed 2024 with 173 customers that spend more than $1 million with Cloudflare per year, a small but disproportionately important wedge.

Cloudflare Workers and Developer Platform Statistics

• Forrester named Cloudflare Workers a Leader in Edge Development Platforms in Q4 2023 in its Wave evaluation.
• Workers run on Cloudflare’s full anycast network, with compute available in every data center city, meaning each of the 337 PoPs hosts the runtime.
• The platform uses V8 isolates instead of containers, delivering sub-millisecond cold starts, the core architectural choice that separates Workers from AWS Lambda’s container model.
• Workers’ developer base, paired with the network’s geographic reach, gives Cloudflare an unusual position: a single product that competes simultaneously with AWS Lambda, Akamai EdgeWorkers, and Fastly Compute@Edge.

DDoS Mitigation and Threat Statistics

• The attack came from the Aisuru-Kimwolf botnet, which operates an estimated 1 to 4 million infected devices globally.
• Bot traffic now accounts for 94% of login attempts on Cloudflare-protected sites, per the 2026 Threat Report.
• The volume of automated bot traffic continues to outpace human activity on every login surface Cloudflare monitors.
• The DDoS arms race framing sits inside a broader cybersecurity statistics pattern.

How big is Cloudflare?

Cloudflare’s most recent full-year revenue (FY2025) was $2,167.9 million, up 30% year-over-year. Its network touches 23.4% of all websites and 95% of the world’s internet-connected population within 50 milliseconds. It runs from 337 cities across 100+ countries and employs 5,156 employees. The company’s 4,298 large customers (over $100,000 annualized revenue) drive 73% of revenue, and its FY2026 revenue guidance ranges from $2,785.0 to $2,795.0 million.

What percentage of websites use Cloudflare?

Per W3Techs’s June 2026 site survey, Cloudflare is used by 23.4% of all websites and 83.5% of all the websites whose reverse proxy service we know. That share climbed from approximately 21.3% of all websites on the Internet in January 2026, a roughly two-percentage-point gain in five months. Among the top 10 million sites ranked by Tranco (the W3Techs sample frame), no other reverse-proxy vendor approaches Cloudflare’s footprint.

Conclusion

Cloudflare’s numbers describe a company that has grown beyond a CDN: 23.4% of all websites, 4,298 large customers contributing 73% of total revenue, 230 billion threats per day blocked, and over 1 million developers building on Workers. The headline gross-margin compression, from 75.9% to 71.2% year-over-year, reflects deliberate investment in compute capacity for an AI-shaped traffic mix the company is already monetizing through Pay Per Crawl.

The next year will test whether Cloudflare can keep a large customer share concentration (73% of revenue) compounding without payback risk while the HTTP 402 economics scale. With the network sending more than one billion HTTP 402 Payment Required responses to AI crawlers every day and FY2026 revenue guidance of $2,785.0 to $2,795.0 million, the company has more upside than downside on both surfaces.
