Qualcomm Stock: Can Cars and Data Centers Offset Apple?

Qualcomm (NASDAQ: QCOM) is betting its next growth chapter on automotive compute and custom data-center silicon, at the exact moment its Apple business is eroding faster than management planned. As of October 21, 2026, the shares are up about 37% over the past six months, even after a 21% slide over the past three months, and still sit roughly 29% below their 52-week high. The first real test arrives in the December quarter, when revenue from two hyperscaler custom-silicon wins is scheduled to begin.

Apple's Exit Is Accelerating — and It Isn't Happening to Qualcomm

The Apple overhang has been the most predictable problem in Qualcomm's business for years, but the pace of the breakup keeps surprising. Management now expects its share of Apple's new iPhone launch to fall materially below the 20% it previously modeled. Apple product revenue is forecast to drop roughly 50% sequentially from the September quarter to the December quarter.

Part of the acceleration is self-inflicted. Qualcomm's own supply constraints, management has acknowledged, contributed to Apple's faster shift onto its in-house modem roadmap. It is a candid admission, and an important one: the iPhone relationship was never going to last forever, and the company's response is finally structural rather than reactive.

Android growth, management says, will "significantly offset" the Apple decline in the December quarter. The bigger fix, though, is the non-handset business. Qualcomm is targeting non-handset revenue growth of more than 60% year over year in fiscal 2027, after 24% growth in fiscal 2026 — enough, management argues, to replace all of Apple's fiscal 2026 product revenue.

The Data-Center Bet: Two Customers, a $15 Billion Target

The most consequential new piece is custom silicon for hyperscale data centers. Four months ago, Qualcomm described a single engagement with a leading hyperscaler. By July, there were two. Management says purchase orders are in hand, wafer production has started, and revenue from both wins is expected to begin in the December quarter. They size the opportunity at $5 billion in fiscal 2027 and $15 billion by fiscal 2029.

Those figures matter beyond the data-center narrative. They sit inside a non-handset revenue target of $40 billion by fiscal 2029, nearly double Qualcomm's earlier goal. Compare that with trailing revenue of $44.07 billion, and the ambition comes into focus: Qualcomm intends to build a second company alongside its first.

The math is demanding all the same. A $15 billion custom-silicon business by 2029 implies capturing a substantial share of the custom accelerator market in roughly three years, starting from just two disclosed customers. That isn't impossible; it's just not yet demonstrable. The December quarter is the first opportunity to demonstrate it.

Cars Are the Part That Already Works

Automotive is the quieter, proven counterweight to the data-center hype. Sales rose 61% year over year in fiscal Q3 2026, another record. In April, management expected a fiscal 2026 exit run rate above $6 billion; by July, that was up to about $7 billion.

The growth is driven by content per vehicle, not just vehicle counts. BMW chose Qualcomm as its lead compute silicon provider for next-generation ADAS and digital cockpit, the kind of marquee design win Qualcomm needs to keep selling elsewhere. The fifth-generation Snapdragon Digital Chassis — which management calls the largest content jump between generations in Qualcomm's history — began ramping in September.

The Execution Question Has Not Been Settled

Qualcomm's CEO was blunt in July: the data-center business is just starting, and investors want proof a new entrant can deliver at hyperscale. That proof won't come from a design-win slide deck. It will come from a revenue line.

The competitive context makes the hurdle steeper. Broadcom and Marvell already hold custom-silicon relationships with the biggest hyperscalers — Google, Meta, Amazon, Microsoft — and have years of demonstrated execution. Industry analysts project the custom AI acceleration market to roughly triple from about $10 billion in 2025 to more than $30 billion by 2029. That's a large enough pie for a third player, but the window to prove reliability is narrow, and hyperscalers punish late or flawed silicon harshly.

Qualcomm does carry real advantages into the fight: its 5G modem and RF technology are increasingly relevant to AI-infrastructure networking; its engineering depth in the industry's most complex mobile chipsets is not easily replicated; and its licensing arm provides a financial cushion that datacom startups never had. The question is whether those strengths translate into $15 billion of annual revenue in three years — with only two customers named so far.

What the December Quarter Must Show

The December quarter will answer three questions at once. First, how large is the inaugural data-center revenue contribution, and does it land on schedule? Second, how steep is the Apple decline on the bottom line? Third, does Android growth actually offset the modem pullback or merely defer it?

If data-center revenue arrives on time and at credible scale, the fiscal 2027 plan earns a hard data point, and the gap to the 52-week high begins to look like an opportunity rather than a warning. If it slips, the entire diversification narrative loses its anchor, and a stock that has already run 37% in six months could give much of it back.

The Bottom Line

There is no shortage of momentum in Qualcomm's history — the stock has gained more than 30% in under two months a dozen times since 2010, most recently in 2026. But the current move depends on a transformation, not just tape. For investors, the December quarter is a reminder that conviction and position sizing are two different decisions, and that the evidence for this story has a date attached to it.
