A look at Apple's work on its in-house modem chip, which may debut in select iPhones in 2025 to replace Qualcomm's chip, with a full rollout taking a few years
Apple's move to drop Qualcomm modem chips won't have a payoff at the outset, but it could set the stage for bigger things later.
Context & Ripple Effects
Apple’s modem effort has been a multi-year attempt to replace a critical iPhone component: the work was underway by 2020, while a 2023 report described snags in the planned Qualcomm swap and a later report pointed to another postponement. That history makes a limited 2025 debut more consequential as a qualification step than as an immediate supplier change.
The reported phased rollout also fits subsequent coverage that placed the first in-house modem in a new iPhone SE and later generations in higher-end products. Apple is therefore approaching the transition as a staged validation program, rather than a single-model cutover.
First-order effects
- Apple can begin validating its own cellular modem in selected iPhones, while Qualcomm remains the modem supplier for models outside the initial rollout.
- A full replacement is deferred over several product cycles, limiting the immediate commercial impact of Apple’s move on Qualcomm.
Second-order effects
- The phased approach makes modem performance and qualification the gating factor for expansion; a delay similar to the previously reported modem postponement would extend Qualcomm’s role.
- As Apple shifts models only after validation, its component planning becomes less dependent on a single external modem roadmap, while Qualcomm faces a gradual rather than abrupt exposure to reduced iPhone demand.
Third-order effects
- If the staged rollout succeeds, Apple would have greater control over a foundational wireless component and could further consolidate chip development inside the company; the pace remains contingent on qualification across more iPhone tiers.
- The case underscores that supplier displacement in complex semiconductors is often incremental: incumbents can retain business during long validation cycles even after a customer commits to in-house development.
The trend: This is one data point in large device makers bringing strategically important chips in-house through slow, qualification-led transitions rather than immediate supplier exits.
