Anthropic's Chip Ambitions Rattle Broadcom: Is the AI Custom Silicon Party Getting Too Crowded?

Quick Take

Broadcom (AVGO) took a hit after a report that AI startup Anthropic is developing its own AI chips and has held talks with Samsung about manufacturing them. While the news spooked the market, Broadcom's massive scale — $63.9 billion in FY 2025 revenue and a 36.2% net margin — makes it a different beast than a pure-play chip designer.

What's Happening

The Information reported that Anthropic, the AI company behind the Claude model, has started developing its own AI chips and is in early-stage discussions with Samsung for fabrication. This is a big deal because Anthropic is a major customer of cloud providers that use Broadcom's networking and custom AI accelerator chips.

But let's keep perspective. Anthropic's chip effort is in its early stages — they're still figuring out processor power and server fit. It took Alphabet years to develop its TPUs, and OpenAI's "Jalapeno" chip was developed in partnership with Broadcom. Custom silicon is hard, and Broadcom is the go-to partner for it.

What Our Data Says

Revenue & Profitability: Best-in-Class

Broadcom's FY 2025 results are staggering:

• Revenue: $63.9 billion, up 23.9% year-over-year
• Net income: $23.1 billion, yielding a 36.2% net margin
• Free cash flow: $26.9 billion — that's a 42% FCF margin

Compare that to peers. Nvidia's gross margin is 74.15%, but Broadcom's 65.66% gross margin is still elite for a diversified semiconductor and software company. And Broadcom's $0.70% dividend yield shows it returns cash to shareholders while investing in growth.

Balance Sheet: Rock Solid

• Debt-to-equity: 0.8x — manageable leverage
• Current ratio: 1.7x — plenty of liquidity
• Stock-based compensation: 27.5% of operating cash flow — a non-cash expense that's worth watching, but not alarming given the cash generation

Customer Concentration: The Real Risk

Here's where the Anthropic news hits hardest. 40% of Broadcom's revenue comes from its top five end customers, and 48% of net revenue flows through distributors. If a major customer like Anthropic decides to build its own chips, that's a direct threat to Broadcom's custom AI accelerator business.

But remember: Broadcom's AI networking chips (Tomahawk, Jericho) are the backbone of data center infrastructure. Even if Anthropic builds its own compute chips, they'll still need Broadcom's networking silicon to connect them.

Valuation & Technicals

Valuation: Not Cheap, But Justified

• P/E ratio: 60x — that's expensive by historical standards, but in line with high-growth AI peers
• Market cap: $1.7 trillion — the market is pricing in continued AI-driven growth
• 52-week range: $269.58 – $495.00 — currently trading near the middle of that range

At $360.22 per share, AVGO is down from its highs but still up 33% over the past year. The 60x P/E multiple reflects the AI premium, but it's vulnerable to any sign of slowing growth.

Technical Setup: Weakness on Volume

• Volume: 1.2 million shares (vs. average of 26.5 million) — the sell-off on low volume suggests it's not a panic, just repositioning
• Day's range: $356.45 – $374.00 — the stock bounced off the low, showing some support
• RSI: Not provided, but the stock is down 2.47% on the day — not oversold yet

The Bull Case

Broadcom is the "picks and shovels" of the AI revolution. Even if Anthropic builds its own chips, they'll need Broadcom's networking silicon, custom ASIC expertise, and infrastructure software (VMware). With $26.9 billion in free cash flow and a 36.2% net margin, Broadcom has the resources to invest through any competitive threat. The 23.9% revenue growth is accelerating, not slowing.

The Bear Case

The custom AI chip market is getting crowded. Alphabet, OpenAI, and now Anthropic are all building their own silicon. If Broadcom loses even one major customer, the 40% customer concentration becomes a real problem. The 60x P/E leaves no room for error — any sign of growth deceleration could trigger a sharp re-rating lower.

Bottom Line

Anthropic's chip ambitions are a real risk, but they're years away from production. Broadcom's AI networking dominance, massive free cash flow, and proven custom chip expertise make it a core AI holding. The sell-off is a buying opportunity for long-term investors, but keep an eye on customer concentration — that's the real risk to watch.
