Wall Street decided QualcommQCOM

was a smartphone chip company and stopped paying attention, right as Qualcomm quietly became something else.

The stock returned just 5% over two years while the PHLX Semiconductor Index surged more than 150%. That depressed valuation is now the setup, and the market priced in permanent smartphone dependency while missing the pivot entirely.

Not just a smartphone story

The smartphone business has real weight. Handsets still account for 57% of Qualcomm's most recent quarterly revenue, and the market itself is deteriorating as smartphone sales are expected to fall 14% this year.

Memory demand from AI projects is crowding out supply for consumer devices. The Apple modem contract, once worth an estimated $5B in annual revenue, is gone after this fall's iPhone cycle as Apple completes its transition to in-house modems.

That's the bear case, and it's already in the stock. CEO Cristiano Amon has spent five years building around those losses.

Automotive revenue hit $1.3B in the latest reported quarter, up from $240M in the same period five years earlier. Analysts forecast ~45% automotive revenue growth in the June quarter, and the IoT chip business generated $1.7B last quarter, up 9% year over year.

Neither of those lines gets discussed in the same breath as Nvidia. That's exactly the problem with how Qualcomm is being valued.

The data-center bet

The company's move into data-center AI is new and unproven. Qualcomm already makes inference chips (processors that run deployed AI models rather than train them) and has a deal to supply custom AI chips to an undisclosed major tech company, using technology from its acquisition of Alphawave last year.

Those chips are expected to start shipping later this year, with Amon set to reveal details at an investor day on June 24.

J.P. Morgan analyst Samik Chatterjee projects Qualcomm could target more than $3B in data-center revenue for fiscal 2027. That figure could potentially reach $35B by 2031.

Qualcomm is also reportedly in talks to acquire AI chip startup Tenstorrent for $8B to $10B, per The Information. Tenstorrent's CEO Jim Keller, a former Apple and AMD chip designer, would be the real prize.

Why the valuation gap is irrational

Qualcomm trades at just over 20 times projected forward earnings. Arm Holdings, also entering the data-center chip space for the first time, trades at ~175 times.

That spread reflects one company Wall Street refuses to reclassify, not two companies at genuinely different stages of execution risk.

Beyond data centers, Amon is building for whatever computing platform follows the smartphone. Qualcomm announced Snapdragon Reality Elite this week, a mixed-reality platform delivering up to 160% improvement in NPU performance, alongside START, a turnkey hardware and software toolkit for smart glasses makers.

Amon told CNBC that smart glasses shipments are already in the "tens of millions" per year and could reach hundreds of millions within a couple of years.

The stock is up 28% this year but still trades like a company with no answer for post-smartphone computing. Qualcomm has over 40 device designs in development and a data-center revenue target that could dwarf its current business. Its biggest upgrade may be its valuation.
