Apple’s longest-running chip project is not a processor, it is a modem. For the better part of a decade the company has been quietly working to design the cellular chip that connects an iPhone to a 5G network, a component it has bought from Qualcomm for years. That project has a codename, a shipping product, and real consequences for every company caught in its path.
The Prometheus program
Apple’s in-house modem effort carries the codename “Prometheus,” and its foundation was a headline deal. In 2019 Apple paid roughly $1 billion to acquire the bulk of Intel’s smartphone modem business, bringing in thousands of engineers and a deep stack of modem patents. That purchase was the shortcut that let Apple skip the first several years of building a team from scratch. Modems are unforgiving parts: a single chip has to talk to hundreds of carrier networks worldwide, pass government certification in dozens of countries, and keep a connection alive through towers, tunnels, and handoffs without draining the battery. That difficulty is exactly why even a well-capitalized company needed years, and why the work has unfolded in stages rather than in one jump.
The C1 modem and the rollout
The first public proof arrived with the C1 modem, which shipped inside the iPhone 16e in early 2025. It was a genuine milestone, the first Apple-designed cellular modem in a shipping handset, and it showed the silicon actually worked in the real world. A second-generation chip has since followed, and Apple has been clear that it intends to migrate its full product line onto its own modems over time. The pattern mirrors what Apple did with its A-series and M-series processors: build the component, tune it on a lower-volume product first, then roll it across the lineup once it is proven.
Why dropping Qualcomm matters
The strategic logic is not subtle. Qualcomm collects a royalty on essentially every smartphone that uses its modem technology, and Apple is its most valuable single customer. If Apple fully insources the modem, that royalty revenue starts to decline, and the savings flow into Apple’s own gross margin instead of out the door. There is a control argument too: owning the modem means Apple is no longer tied to Qualcomm’s release schedule, its roadmap, or its patent terms. None of this happens overnight. Apple is likely to phase the change across models and price tiers over several years, keeping Qualcomm inside some products while it proves out the rest. But the direction of travel is unambiguous, which is why the words “Apple modem” move share prices in two directions at the same time.
The supplier angle in the teaser
That is the backdrop for a recent Paradigm Press promotion from James Altucher, which points investors at a small “Apple supplier” it says will ride the modem shift. The company the teaser circles is Ceva Inc., a Rockville, Maryland firm that licenses digital-signal-processor and connectivity intellectual property to chipmakers rather than manufacturing chips itself. The logic is that any modem needs signal-processing blocks, and Ceva is one of a handful of firms that license exactly that kind of design. It is a plausible story rather than a confirmed one. An Apple design win is not public fact, and even a real supply relationship does not automatically translate into the kind of return the promo implies. We walk through the royalty mechanics and the competitive picture in our companion piece on Ceva’s IP licensing business, and the broader context in our semiconductor stocks explainer.

What to watch next
Investors trying to handicap this story should watch two signals. The first is the mix of iPhones that ship with an Apple modem versus a Qualcomm one, which shows how fast the insourcing is actually moving. The second is any public disclosure from the suppliers Apple is said to be working with, because a design win usually shows up in a licensing announcement or a contract note before it shows up in revenue. Until either signal lands, the Apple-modem trade is a thesis about direction rather than a confirmed contract.
Why Apple wants control
The royalty savings are only part of the motivation. A modem that Apple designs itself can be integrated more tightly with its own processor, tuned for the same power and thermal budgets, and scheduled on Apple’s roadmap rather than a supplier’s. Apple ran this play with its M-series chips, and the payoff was measurable gains in efficiency and battery life that a third-party part could not deliver as cleanly. The same logic applies to the modem: owning the silicon means owning the tradeoffs. For a company that sells on polish and battery life, that control is worth as much as the royalty savings, which is why the program is unlikely to be abandoned even if the near-term cost savings prove modest.
