Apple Locks In Broadcom Through 2031, and Custom Connectivity Is Still Scarce

Bottom line

Apple is not fully in-sourcing connectivity, and that is the point.

The obvious reading of the Apple-Broadcom extension is that Apple is locking in supply. The deeper reading is that Apple still needs an external partner for a critical part of the device stack: wireless, RF, Wi-Fi, Bluetooth, and other connectivity components that sit close to the user experience but far from the consumer headlines.

That is strategically important because Apple has been bringing more silicon in-house elsewhere. The parts it still buys externally are exactly the parts where reliability, integration, and manufacturing execution matter most. In other words, the company is keeping the layers it cannot easily commoditize.

My view: this is not a supplier press release. It is evidence that the connectivity layer still has real pricing power and real switching costs.

Concentration

Broadcom looks less like a neutral commodity vendor and more like a concentrated infrastructure dependency.

Broadcom's 2025 annual report says distributors accounted for 48% of semiconductor revenue and that sales to the top five end customers, through all channels, were about 40% of net revenue. MacRumors, citing Reuters, says Apple is believed to represent about 20% of annual revenue. That combination is not a wide-moat platform story; it is a high-dependence customer-stack story.

The practical implication is that Broadcom gets durability when the customer keeps building high-volume devices, but it also inherits concentration risk. If one major customer shifts an architecture or delays a product cycle, the earnings line can move before the market has time to re-underwrite the rest of the business.

Broadcom's revenue mix still shows high customer concentration

These are concentration indicators, not a single apples-to-apples metric. The point is how much of the business sits in a few channels and customers.

Supply chain

The chain runs from U.S. manufacturing to the RF layer to the next device cycle.

Apple's 2023 announcement said Broadcom would develop 5G radio frequency components and wireless connectivity parts in several U.S. manufacturing hubs, including Fort Collins, Colorado. The new extension says the relationship is still strategic, not legacy.

That matters for the broader supply chain because connectivity sits downstream of the modem story but upstream of the user experience. If Apple keeps its modem roadmap internal while keeping Broadcom on RF and wireless, the company is effectively splitting its stack between what it must own and what it still prefers to source from a specialist.

Where the strategic value sits in the stack
Layer	What Broadcom supplies	Why Apple still needs it
RF front end	Filters and related components	Signal quality and device reliability
Wireless connectivity	Wi-Fi / Bluetooth chips	Low-power performance across the product line
Manufacturing footprint	U.S. build-out and partner capacity	Supply assurance and political signaling
Revenue model	Long-lived customer concentration	Predictability, but also hidden dependence

My conclusion

The read-through is bigger than Apple: custom connectivity is still scarce, and scarcity still gets paid for.

If Apple still wants a long-term contract for this layer, that tells you the bottleneck is not over. It also tells you the broader semiconductor market should not confuse custom AI silicon with the only strategic custom-silicon game in town. Connectivity, RF, and networking remain structurally important even when the spotlight is on accelerators.
