Apple Opens Siri to Claude at WWDC 2026, Breaking the Monopolistic Model of Apple Intelligence

In his last conference as CEO, Tim Cook announced an Extensions system in iOS 27 that allows users to choose Claude, Gemini, or ChatGPT as the engine for Apple Intelligence. A $1 billion per year agreement with Google becomes the default.
Tim Cook opened WWDC 2026 on Monday, June 8, in his final edition as CEO of Apple. The central message breaks a three-year promise of a revamped Siri: Apple has moved away from betting everything on a single proprietary model and has opened Apple Intelligence to three direct rivals. In iOS 27, iPadOS 27, and macOS 27, users can choose Anthropic Claude, Google Gemini, or OpenAI ChatGPT as the assistant engine within a system called Extensions.
The default goes to Gemini. According to Bloomberg, Apple will pay approximately $1 billion per year to Google to license a customized 1.2 trillion parameter Gemini model, operating within the Private Cloud Compute, a confidential infrastructure that Apple runs on in-house silicon to prevent user data from leaving the perimeter. This is the first time Cupertino has paid a licensing fee for a cutting-edge model to a direct competitor in search after years of resisting the idea.
The inclusion of Claude changes the game for Anthropic. The model becomes a native option on iPhone, iPad, and Mac for the first time, without the need for a third-party app. For Anthropic, which filed its confidential S-1 on June 1 aiming for a valuation in the range of $965 billion, the direct window to the active base of 1.4 billion iPhones is the kind of distribution that institutional money prices in before an IPO.
Why Apple Abandoned Monogamy
Apple had previously promised a new Siri with deep reasoning and personal context in 2024. It delayed. The system rolled out in January 2026 under harsh criticism from analysts and corporate customers. Meanwhile, ChatGPT, Claude, and Gemini have grown in consumer and enterprise usage. Maintaining a single partner became a competitive risk. The solution was to treat AI as an infrastructure layer, just as Apple Pay treats banks: the user chooses, and Apple charges rent.
The Extensions allow routing queries by task type. Users can set Claude for coding in Xcode, Gemini for multimodal search, and ChatGPT for creative writing, all within the same Siri layer. Apple did not disclose the economics for Anthropic and OpenAI, but the revenue-sharing model is similar to the search agreement: the company that receives the call pays Apple for qualified traffic.
The Message to Corporate Software Vendors
This move carries immediate implications for CIOs. SAP and ServiceNow already operate in a multi-model architecture, but Cupertino's signal validates that even the most centralized company in the world has accepted: there is no single model. Mustafa Suleyman, AI CEO at Microsoft, reiterated last week in an interview with Bloomberg that Anthropic is "extremely expensive" and that Microsoft's goal is to "reduce and ultimately eliminate" that cost. The same reasoning applies at the corporate level. Buying lock-in with a provider is expensive today and will be prohibitively so in three years.
The impact in the UK and Germany, where data residency matters, stems from the technical detail of the announcement: the models run within Apple's Private Cloud Compute, in data centers in the United States, the European Union, and Japan. For a European bank under DORA, this reduces friction for deploying corporate Siri on employees' iPhones without triggering a third-party vendor review.
In Japan, where Apple operates a PCC center in Osaka, iOS 27 opens the possibility for companies like MUFG and Mizuho to use Claude directly in internal workflows without renegotiating contracts with Anthropic, as Apple acts as an intermediary. The same reasoning applies to Brazilian IT players in projects for Itaú and Bradesco, who are already testing Gemini and Claude and now gain a native corporate iPhone channel.
What's Left for Developers
Xcode 26.3 has already included the Claude Agent SDK and OpenAI's Codex running natively for agentic coding tasks since February. The WWDC step was to export this logic beyond the IDE, towards the end user's iPhone. For the product team of any B2B SaaS company, the operational question became straightforward: which part of my usage flow can now be mediated by Claude's Siri Extension without the user leaving my app?
Apple did not announce a specific date for the availability of Claude and ChatGPT Extensions in Brazil. Gemini will be available as the global default at launch. Beta 1 of iOS 27 was released to developers on the same afternoon as the keynote.
