Qualcomm Rises 5% on Multi-Generation Amazon AI Silicon Deal; Broadcom Ticks Up, Amazon Holds Flat

A multi-generation AI silicon supply deal is powering Qualcomm (NASDAQ:QCOM | QCOM Price Prediction) shares in Tuesday morning trading, handing the chipmaker a marquee data-center credential well outside its handset franchise. The counterparty is Amazon (NASDAQ:AMZN), whose AWS unit will co-develop customized silicon at scale with Qualcomm for large-scale AI inference workloads. The reaction reads squarely as a Qualcomm story, which fits the shape of the announcement.

Broader benchmarks are lower: the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 0.47%, so the chip names are climbing against a softer tape. Qualcomm stock is up 5% to $177.60 in early trading. At the same time, Broadcom (NASDAQ:AVGO) stock is rising 3% to $367.10 on read-through to the custom AI silicon category.

Amazon stock is down 1% to $255.65 as the buyer folds another silicon supplier into its AWS mix. Notably, Qualcomm stock was up 5% year to date (YTD) heading into the session, meaning today’s move accounts for essentially all of that advance. Qualcomm’s market capitalization sits near $189.7 billion against Broadcom’s $1.755 trillion, framing the scale gap between the two AI silicon stories.

Amazon Deal Validates Qualcomm’s Data-Center Push

Deal details include customized silicon built for AI inference at hyperscale, plus high-performance optical connectivity that leans on Qualcomm’s SerDes and optical DSP portfolio. Qualcomm will also deepen its own use of AWS for electronic design automation workloads, which management pitches as a way to compress chip design cycles. CEO Cristiano Amon said data center infrastructure needs advances in both computing and connectivity to deliver greater performance with more efficiency.

Amon has been steering the company toward a $40 billion non-handset revenue target by fiscal 2029, with the data center as the accelerator. On the July earnings call, he guided non-handset revenue growth to accelerate from 24% in fiscal 2026 to greater than 60% in fiscal 2027, and flagged data-center revenue of $5 billion in fiscal 2027 rising to $15 billion by fiscal 2029. The Amazon collaboration appears to confirm and expand the hyperscaler custom silicon engagement Qualcomm previewed on its Q2 FY2026 call.

Broadcom’s Read-Through and the Custom Silicon Category

Broadcom is the incumbent in custom AI accelerators and hyperscaler networking, so a fresh Qualcomm win could easily have been read as share migration away from the leader. Instead, Broadcom shares are climbing alongside Qualcomm, which points to broad validation of the custom silicon category across suppliers.

Broadcom’s own numbers make the demand backdrop clear. Last week, the company posted AI semiconductor revenue of $16.7 billion, up 221% year over year (YoY), and guided Q4 FY2026 AI revenue to approximately $21.7 billion. CEO Hock Tan told analysts “demand for our custom AI accelerators and networking continues to be very strong.”

The optical connectivity dimension of the Qualcomm-Amazon deal overlaps directly with Broadcom’s dominant optical DSP franchise. On its September earnings call, Broadcom management flagged Tomahawk 6 deployments at essentially every AI hyperscaler and said demand for EML and CW lasers is far outstripping industry supply, which frames the connectivity buildout as a rising-tide dynamic across suppliers (we profiled seven companies riding that same AI infrastructure buildout, from power to cooling to networking, in a free report here).

Amazon, for its part, keeps stacking silicon suppliers to lower the cost of inference and preserve customer choice. CEO Andy Jassy said on the July call that AI and Chips businesses each exceeded $25 billion annualized run rates growing triple-digit percentages, with OpenAI committing roughly 2 gigawatts of Trainium capacity and Anthropic up to 5 gigawatts. Qualcomm now joins Trainium and Graviton in the AWS chip roster, giving the lineup another optionality lever without dislodging incumbent silicon programs.

What to Watch

The immediate question is whether Qualcomm’s morning gain holds into the close. The announcement didn’t carry committed volume, disclosed revenue, or a delivery timetable, and that gap is precisely what would turn a credential into an earnings line. Analyst notes on non-handset ramp acceleration should shape the next leg for Qualcomm shares.

Investors sizing their exposure to the AI silicon trade may want to watch for durability in Broadcom’s sympathy move, since the incumbent’s reaction is the cleanest read on how this deal gets framed. Furthermore, traders can keep an eye on the stock for any Amazon commentary that quantifies volumes or timelines, which would push the story from category validation toward a countable revenue line.

Given the absence of hard volume or delivery details, keeping their position sizing modest makes sense until Qualcomm quantifies the ramp. Qualcomm stock carries a P/E ratio near 33x, which already prices in some data-center optimism, so any disappointment on cadence could cool sentiment quickly.
