Cloudflare: The Invisible Infrastructure of the Internet

Cloudflare (NYSE: NET) may be a company you've never heard of, but you use it every day. Nearly 20% of global internet traffic passes through Cloudflare's network. When you browse websites, use mobile apps, or stream videos—there's a high chance Cloudflare is behind the scenes, accelerating and protecting everything.

Key Data:

• Q1 2026 revenue $639.8 million (+34% YoY)
• Global edge nodes in 300+ cities
• Carries ~20% of global internet traffic
• Gross margin 71.2%
• 4,416 large customers spending $100K+ annually (72% of revenue)
• Million-dollar contracts +73% YoY

Cloudflare's vision: To become a "layer" of the Internet. Every request, every data transfer, every AI inference—all routed through Cloudflare's edge network.

*Edge nodes in 300+ cities worldwide—Cloudflare's physical infrastructure footprint is its deepest moat. Cloud hyperscalers cannot replicate this scale in a short timeframe.*

I. The Global Edge Network Platform Business Model

① CDN Website Acceleration & DDoS Protection — The Customer Acquisition Engine

Core Logic:

CDN is Cloudflare's "hook." The free tier attracts millions of small and medium websites → some grow and convert to paid plans → larger ones become enterprise customers → purchasing more modules. This is a "free → paid → enterprise" funnel model.

Scale = Moat. Cloudflare carries 20% of global internet traffic → bandwidth costs are spread extremely thin → it can offer a free tier without losing money → more websites join → flywheel effect.

② Cloudflare One Zero Trust SASE — The Core High-Margin Business

Difference from Zscaler:

Zscaler = Pure-play security company, started from zero trust.

Cloudflare = Started from CDN, using its edge network advantage to "invade in reverse" the security market.

Cloudflare's argument: "Our edge network is already near all your users—why not let us handle security while we're at it?" This cross-sell strategy has allowed Cloudflare to rapidly capture share in the SASE market.

③ Workers Edge Computing + Workers AI — The Second Growth Curve 🔥

*Edge Computing + AI Inference — Cloudflare Workers AI pushes computation from the central cloud to the edge node closest to the user.*

Why Does Workers AI Matter?

Traditional AI inference = Running GPUs in central cloud data centers → high latency + high cost.

Edge AI inference = Running lightweight inference on the node closest to the user → extremely low latency + higher GPU utilization.

Traditional cloud inference: User → Internet → Central data center → GPU → Return (latency 100-300ms)
Edge inference: User → Nearest Cloudflare node → Lightweight GPU → Return (latency <50ms)
→ Faster, cheaper, and better suited for real-time AI applications

If AI Agents run at the edge rather than the central cloud → Cloudflare could become "the distribution network for AI compute." This is a bigger market than CDN.

④ Ancillary Value-Added Services

Every value-added service makes it harder for customers to leave—this is the "platform lock-in effect."

Overall Profit Logic

One global edge infrastructure → Supports all products (CDN + Security + AI + Value-Added)
→ Marginal cost continues to dilute
→ Free SMB customers = traffic entry point → Convert upward to enterprise paid
→ Security + Edge AI both pull subscription revenue
→ Free cash flow continues to improve

III. Bull vs. Bear Investment Thesis

🟢 Bullish Catalysts

1. The Globally Unique Edge Network — Difficult for Cloud Hyperscalers to Replicate

300+ city nodes + 20% of global internet traffic = Cloudflare's physical moat. AWS, Azure, and GCP have data centers, but they are "central cloud" architectures with far fewer nodes than Cloudflare. To replicate this coverage = billions of dollars + several years.

2. AI Inference Migrating to the Edge — Workers AI Opens a New Ceiling

AI moves from training to inference → inference latency becomes critical → edge inference demand explodes. Workers AI + Anthropic partnership = seizing the "edge Agent runtime" track. If AI Agents run at the edge → Cloudflare becomes the AI compute distribution network.

3. Zero Trust Security Rigid Demand + Cross-Sell Upsell

Enterprise cloud migration + remote work → SASE zero trust becomes a necessity. Cloudflare cross-sells security modules from CDN → per-customer ARR continues to climb.

4. Free Products = Continuous Customer Acquisition Pipeline

Millions of free users → some grow into paid → larger ones become enterprise customers. This funnel model gives Cloudflare a customer acquisition cost far lower than pure-play enterprise SaaS.

5. Explosion in Large Customer Orders

Million-dollar contracts +73% YoY = large enterprises are purchasing at scale. Once embedded into an enterprise's core infrastructure → switching costs are extremely high.

6. Layoff and Restructuring → Margin Improvement

Layoff of 1,100 = optimized cost structure. FCF margin rising from single digits to 13%+ → proves the scale effect is being realized.

7. $100B+ TAM

Global CDN + Security + Edge Computing market >$200 billion. Cloudflare's penetration is still low.

🔴 Core Risks

1. Extremely High Valuation — 80x Forward P/E

80x P/E = the market is pricing in "hyper-growth continues." Any signal of growth deceleration → valuation compresses sharply. Extremely low margin for error.

2. Q2 Growth Decelerating to 30% — Downward Trend

Slowing from +34% to +30% → although still high growth, the trend is concerning. If it further slows to +20-25% → 80x P/E cannot hold.

3. Cloud Hyperscaler Bundling Competition

AWS CloudFront + AWS Shield, Azure Front Door, Google Cloud CDN → cloud giants bundle CDN + security for free or at low prices. SMB customers may be diverted.

4. Long-Term GAAP Losses

Non-GAAP margin improvement = a good sign, but GAAP is still loss-making. Stock-based compensation + amortization = real costs. If the market prefers GAAP profitability → Cloudflare gets penalized.

5. Bandwidth Costs Rise with Traffic

Although scale effects lower the cost per unit of traffic, total bandwidth cost rises as traffic grows. If CDN bandwidth cost growth > revenue growth → gross margin comes under pressure.

6. Edge AI Revenue Limited in the Short Term

Workers AI has a broad outlook, but the near-term commercial revenue scale is limited. Edge AI needs time to mature → difficult to offset the deceleration of traditional business in the short term.

7. Layoffs Impact Sales

The layoff of 1,100 may temporarily affect the pace of sales expansion → competitors seize the opportunity to grab deals.

IV. Comprehensive Investment Judgment

Short-Term Speculation (1-3 months): ⚠️ High Risk

Long-Term Value Allocation (3-5 years): ✅ Bullish (High Risk, High Return)

Long-Term Operating Approach:

• Edge Computing Theme Investor: Cloudflare is the pure-play in the "edge cloud" track. If you believe "computation moves from central cloud to the edge" → NET is the best exposure
• AI Infrastructure Investor: Workers AI = edge AI inference. If AI Agents need low-latency edge computing → Cloudflare's position is unique
• Portfolio Pairing: NET (edge cloud) + NVDA (AI compute) + ZS (zero trust security) = AI infrastructure triangle
• Not Suitable For: Investors who require GAAP profitability, conservative investors who cannot withstand -50% volatility, value investors who are allergic to 80x P/E

Key Metrics to Monitor

Conclusion: The Invisible Monopolist of the Internet

Cloudflare's investment thesis can be distilled as:

If the Internet is a city, Cloudflare is the city's road system—everyone has to traverse it, but very few people pay attention.

• 20% of global traffic passes through Cloudflare → physical infrastructure monopoly
• Free → Paid → Enterprise → Security → AI = funnel-style growth flywheel
• Workers AI = upgrading from "Internet roads" to "AI roads"

But 80x Forward P/E means:

Cloudflare needs to keep proving that it can sustain 30%+ growth. Any single "deceleration" will be severely punished by the market.

"Cloudflare may be the world's most undervalued infrastructure company—but 'undervalued' and 'stock price will rise' are two different things. At 80x P/E, you need more than a good company, you need it to keep beating expectations."

"If edge AI becomes mainstream, Cloudflare could be the biggest AI beneficiary after Nvidia—because AI needs not just compute, but also a distribution network. And Cloudflare already owns the world's largest distribution network."

Final advice: NET is a textbook high-risk, high-return name. Control your position (3-7%), be mentally prepared for -50%, and watch Q2 growth—that is the correct way to invest in Cloudflare.
