Broadcom and Apple Extend Custom Chip Supply Deal to 2031

A long-dated lock-in between Broadcom and one of its largest customers is the kind of announcement that lands harder in the supply chain than on the leaderboard. Broadcom said Monday that it has extended its custom chip supply agreement with Apple through 2031, covering multiple generations of Apple products, according to Reuters. Broadcom shares climbed roughly 4% in premarket trading on the news.

The scope, as reported, is the familiar Broadcom bill of materials for an iPhone: radio frequency chips used for cellular connectivity, Wi-Fi and Bluetooth chips, and other networking semiconductors, with custom ASIC work sitting alongside. Apple represents about 20% of Broadcom's annual revenue, which is why a multi-year renewal moves the stock even when the underlying business relationship is not really a surprise.

Why this matters if you are not tracking chip supply for a living: Apple has spent years trying to bring more of its silicon in-house, including its own C1 modem, and yet it is still signing long-dated agreements for the wireless pieces. Take that as the market telling on itself. In-house RF is a harder problem than in-house application processors, and with TSMC capacity strained by AI-driven demand, Apple is buying certainty on the parts it does not want to gamble on.

The honest caveat is that the reporting does not put a dollar figure on the extension, and it does not break out how much of the deal is custom ASIC versus the existing RF and connectivity categories. A 20% customer concentration is also a two-way risk. If Apple's own modem eventually scales broadly, Broadcom's iPhone content could shrink well before 2031 even with a signed contract in hand.

For Broadcom, the near-term win is a revenue floor stretching through the end of the decade, useful cover as it pours capital into AI accelerators for hyperscalers. For Apple, the win is boring and important: a predictable RF and connectivity roadmap while it keeps chipping away at vertical integration. Take the specifics as reported, not settled, but the direction is a company that wants its own silicon still choosing to sign a long lease on someone else's.
