Apple is about to open up the iPhone in Brazil in a way that would have sounded unthinkable a few years ago: alternative app stores, third-party payment systems, and a new business model for developers, all baked into iOS itself, starting with iOS 26.5. It’s a big moment not just for Brazil’s tech ecosystem, but for the ongoing global tug-of-war over how much control Apple should have over its platform.

For once, this isn’t Apple changing course voluntarily. The story starts with Brazil’s antitrust regulator, CADE (Conselho Administrativo de Defesa Econômica), which has been probing Apple’s App Store rules and payment policies for roughly three years. That investigation ended in a settlement, approved in late 2025, that effectively forces Apple to open iOS to rival app stores and competing payment systems in Brazil. Apple was given 105 days to implement these commitments, and the company is now rolling them out in iOS 26.5 as part of what it frames as a carefully controlled, security-conscious expansion of choice.

So what exactly is changing? Apple says that, beginning with iOS 26.5, developers will be able to distribute apps to Brazilian users through alternative app marketplaces, not just the App Store. Those marketplaces can be run by third parties or even by developers themselves, as long as they go through an authorization process with Apple and agree to ongoing requirements. In practical terms, that means you could eventually see Brazilian-focused app stores, niche marketplaces around gaming or streaming, or big global players trying to establish a presence alongside Apple’s own store.

This is not full sideloading in the Android sense, and Apple is very clear about that. Users still won’t be able to download arbitrary app files directly from the web and install them on their iPhones. Every app that lives outside the App Store will still have to come through a registered alternative marketplace that Apple has approved, which lets the company maintain a layer of control over distribution. Apple is following the same basic template it used when it was forced to open up iOS in the European Union under the Digital Markets Act, just tailored to Brazil’s legal framework.

There’s also a major change on the money side. Under the deal with CADE, Apple must allow developers to use third-party payment processors for in-app purchases, display alternative payment options alongside Apple’s own system, and even link out to external websites where users can complete transactions. For consumers in Brazil, that means you may start seeing apps that let you choose between Apple’s in-app purchase flow and another payment option, or send you to a web page to finish buying a subscription or digital good. Apple is required to keep any messaging around those alternatives neutral and objective, rather than scaring users away from rival payment options with ominous warnings.

Of course, Apple is not opening up the platform out of pure public spirit. Alongside the new freedoms, it’s rolling out a fresh business model that preserves a meaningful cut of digital commerce on iOS, just in more complex ways. For apps that stay in the App Store, Apple’s commission in Brazil drops to 10 percent for developers in its Small Business, Video Partner, and certain other programs, and for subscriptions after the first year; for everyone else, it sits at 21 percent of digital goods and services revenue. If a developer continues to use Apple’s own in-app purchases, Apple adds a 5 percent payment processing fee on top, effectively turning that into an optional premium payment rail.

If a developer chooses to steer users to the web instead — for example, by including a button that opens an external payment page — Apple will still charge a Store Services Commission on those transactions. That fee is 15 percent by default, dropping to 10 percent for eligible programs and for subscriptions that are in their second year or later. And if a developer goes further and distributes their app entirely through an alternative marketplace, Apple will apply a 5 percent Core Technology Commission on sales of digital goods and services, including paid app downloads. In other words, even outside the App Store, Apple wants to be compensated for providing the underlying iOS platform and its APIs.

This is the same philosophical stance Apple took in the EU: more options for distribution and payments, but an expectation that any meaningful business happening on iOS generates some revenue for Apple. The company argues that this is fair for the infrastructure, tools, and OS development work it does, while critics see it as Apple trying to reinvent its App Store toll in a more regulation-friendly wrapper. For developers, the reality is going to come down to spreadsheets and trade-offs: which mix of App Store presence, alternative marketplaces, and payment flows produces the best margin and reach in Brazil.

Because regulators are understandably nervous about what happens to user security when you open the floodgates even a little, Apple is leaning heavily on a narrative of safety and child protection. Apps that are distributed outside the App Store will have to go through what Apple calls Notarization for iOS, a review process that combines automated checks with human inspection to hunt for malware and known security threats. The alternative marketplaces themselves must be authorized by Apple and meet ongoing standards, and Apple says it has worked with CADE to design safeguards with a particular focus on keeping children away from inappropriate content and scams.

There are some hard lines here. Apps aimed at children are not allowed to use external payment links or alternative payment systems at all, and any non-Apple payment flow must respect parental controls for users under 18. Apple will also require that alternative payment options be clearly distinguished from its own system in the interface, so users understand who is actually processing their transaction. If you choose Apple’s in-app purchase, you keep all the usual App Store tools: subscription management, purchase history, and the ability to report suspicious charges through Apple’s systems. If you pick a third-party payment, you’re trusting that provider’s support, refund, and security policies instead.

Behind the scenes, this Brazilian deal is also time-boxed and closely monitored. The agreement with CADE runs for three years from the moment the new terms become mandatory for developers, and regulators have left the door open to extend or revisit it if they feel the pro-competition goals aren’t being met. Failure to comply could expose Apple to fines of up to roughly 150 million Brazilian reais and even a reopening of the antitrust case. That kind of pressure gives CADE real leverage if Apple’s implementation feels too restrictive or hostile to competitors in practice.

Developers now face both new possibilities and a looming deadline. Apple has updated the Apple Developer Program License Agreement globally, and every current member of the program must accept the new terms by July 6, 2026. This isn’t something you can delegate to a random team member: Apple is clear that the official Account Holder needs to log in and accept the agreement, or the account risks losing access to the new Brazil-specific distribution and payment options. For teams with a serious Brazilian user base, that means acting quickly, running revenue impact scenarios, and deciding whether it makes sense to launch on alternative marketplaces the moment iOS 26.5 ships.

From a Brazilian consumer’s perspective, the impact will probably roll out gradually rather than overnight. Apple’s update creates the legal and technical framework, but it will take time for alternative marketplaces to get authorized, for local companies to launch their own stores, and for big global developers to experiment with different distribution models. There’s also a behavioral question: even if new stores appear, will users actually download them, trust them, and remember to check them for new apps and updates? In the EU, early signs suggest that most mainstream users are sticking with the App Store by default unless they have a specific reason to look elsewhere, and Brazil may follow a similar pattern.

Still, for Brazil’s tech ecosystem, this is a meaningful shift. Local startups and regional players get more room to experiment with business models that didn’t fit neatly inside Apple’s old one-size-fits-all App Store rules. Payments can potentially become more competitive, with local processors offering better rates or tailored services that reduce friction for Brazilian users. And if alternative marketplaces take off, they could curate experiences that the App Store doesn’t prioritize — whether that’s indie games, hyper-local services, or apps that cater specifically to Brazilian culture and commerce.

The bigger picture is that Brazil has just joined a growing list of jurisdictions that have forced Apple to bend on its long-standing insistence that the App Store is the only safe and acceptable way to install apps and handle payments on iOS. The EU’s DMA was the first big crack; now Brazil’s CADE has carved out its own version of an open-ish iOS. Other regulators in markets like the United States and Asia will be watching closely to see what actually happens in Brazil: whether security issues spike, whether competition meaningfully improves, and whether Apple’s new fee structures still look too much like the old ones in disguise.

For Apple, this is a delicate balance. It wants to defuse regulatory heat, keep its narrative about privacy and security intact, and preserve a business model that still generates billions in services revenue every quarter. For developers, it’s a new and slightly messy reality where “the App Store tax” turns into a more complex mix of commissions, technology fees, and strategic choices about where and how to sell. And for users in Brazil, the next couple of years will be a live experiment in what a slightly more open iPhone looks like in practice — one that could end up shaping how iOS works far beyond the country’s borders.
