Here’s why Broadcom stock is rallying on Tuesday

Broadcom stock (NASDAQ: AVGO) climbed Tuesday as investors reassessed the chipmaker's ability to convert a massive $73 billion AI order book into durable revenue growth.

The stock bounced back from an earlier December sell-off, with the market now focusing on supply wins and backlog visibility rather than near-term margin worries.

A fresh 10% dividend increase also signaled management's confidence that strong cash flows will sustain even as AI chip revenues eclipse traditional business lines.

Broadcom stock: The growth story investors are buying

Here's what shifted sentiment: Broadcom disclosed a $73 billion backlog of AI semiconductor orders set to ship over the next 18 months.

That number towers above what Wall Street was expecting and demolishes any narrative that demand is cooling.

The company's AI revenue reached $6.5 billion in the fourth quarter alone, a 74% jump year-over-year.

That would represent 150% growth, a figure that has convinced analysts across the Street that Broadcom's infrastructure role in the AI boom is secure.

A Bank of America analyst highlighted something crucial: the expanding customer base for Broadcom's custom accelerators (known as XPUs).

New hyperscaler customers like Anthropic added $1 billion in incremental demand in Q4, signaling that the backlog isn't concentrated in a single buyer.

That matters. When AI demand looked fragile in mid-December, worried traders feared a customer concentration risk, what happens if one giant cloud provider cuts orders?

The backlog depth answers that question: Broadcom has real, diversified demand running across 2026 and into 2027.

Goldman Sachs noted ongoing momentum across both XPU and networking, and pointed to Broadcom's dominance in the fabric that stitches together AI data centers.

That's the less exciting but critical part of the infrastructure stack.

While everyone watches Nvidia's GPUs, Broadcom's networking chips and custom silicon are equally indispensable, and carry better economics for the company once you control for volume.

Dividend boost and margin flashpoints that matter

Broadcom announced a 10% quarterly dividend increase, from 59 cents to 65 cents per share, payable December 31.

This marks the fifteenth consecutive annual dividend hike since 2011, a track record that matters to income-focused institutional investors.

For dividend-growth portfolios, Broadcom's payout ratio sits at roughly 50%, leaving room to grow even as capex rises.

Here's the tension traders are wrestling with: AI chip revenue is booming, but it carries lower gross margins than Broadcom's traditional networking and software businesses.

Management guided for Q1 2026 gross margins to dip about 100 basis points sequentially, a real headwind in percentage terms, even if dollar margins keep expanding.

The sell-off on December 12 happened because some investors heard "margin compression" and forgot to ask: "But on what revenue base?"

The backlog answers that. AI revenue will more than double, and dollar margins should expand significantly in absolute terms, offsetting the percentage squeeze.
