iPhone 18 Pro Price Is Up $100. I Told You AI Memory Would Do This.

Last updated September 9, 2026

Yesterday I published a post saying AI memory chip prices were going to land on your next phone. It took Apple about 24 hours. This afternoon at its September event, the company put a $100 increase on the iPhone 18 Pro and Pro Max, and CNBC’s reporters in the room tied it directly to the memory shortage I was writing about.

Here’s what got announced, what it costs, and how I’d think about buying one.

What Apple Announced and What It Costs

There are four things: the iPhone 18 Pro and Pro Max, the first foldable iPhone called the Duo, AirPods 5, and the Apple Watch Series 12. The Pro starts at $1,199 and the Pro Max at $1,299, according to Apple’s announcement, with pre-orders opening September 12 and phones in stores September 18.

The Pro looks a lot like last year’s 17 Pro, with two new colors, glacier and burgundy, and a new A20 Pro chip that Apple says is the first phone chip built on TSMC’s 2-nanometer process. The camera gets a 48-megapixel main sensor with physical aperture blades, and there’s a feature called Apple Reference Image that signs photos at the sensor so you can prove one was taken on the phone rather than generated by AI. That last one won’t be available in the EU or China.

The iPhone Duo is the headline. It opens like a small notebook to a 7.6-inch screen, has a 5.4-inch screen on the outside, and starts at $1,999 for 256GB. Pre-orders start October 16 and it ships October 23.

Why the Price Went Up

The $100 comes from the same memory squeeze that already raised MacBook and iPad prices in June.

CNBC’s live coverage put it plainly: the increase comes “amid a global component shortage, especially for memory,” and the same report notes Apple raised Mac and iPad prices over the summer for the same reason. The mechanism is the one I laid out yesterday. Samsung, SK Hynix, and Micron are pointing most of their factories at the high-bandwidth memory AI data centers buy, so the ordinary memory in a phone costs more, and Apple passes that along.

The A20 Pro is a real step up on paper. Apple says the CPU is up to 20 percent faster, the GPU up to 40 percent, and memory bandwidth up 50 percent, per CNBC’s rundown of the chip. You’re paying more partly for a better chip and partly for the same memory at a higher price.

What Siri AI Actually Does Now

Siri AI is the version Apple announced in June, and it ships in English beta with the new phones, with more languages in October and no availability in the EU at launch.

The demos were everyday stuff. Apple describes it as an “entirely new version of Siri” that “can take action in the apps you already use, including third-party apps,” plus a Siri mode inside the Camera app and a “Notify Me” feature in Safari that watches a web page for changes. Apple says it works with more than 300,000 apps, which is the part that separates it from the old Siri if it works.

The Apple Watch Series 12 got the feature that drew the most attention. Audio Intelligence uses the watch microphone to let you rewind the last 15 seconds of a conversation, and Siri Recap uses what Apple calls ambient listening to write a title, summary, and key points from a meeting or a parent-teacher conference. Apple says audio isn’t stored or sent to Apple. It’s in beta later this year. If you’ve been running the iOS 27 Siri beta since summer, this is the finished version of that.

Should You Upgrade?

If your phone works, keep it. If it doesn’t, buy last year’s model.

I said yesterday that paying more for a phone that does nothing new for me isn’t a trade-off I’ll make, and the 18 Pro is a $100 increase on a phone that looks like the 17 Pro. The chip is faster and Siri AI is real, but Siri AI is a software feature in beta, and the useful parts of it will land on phones people already own. The 17 Pro usually drops in price once the new one lands, and it was priced before the memory squeeze started.

The Duo is a different question. It’s a first-generation foldable at $1,999, and it doesn’t ship until October 23. If you’re in the EU, the Reference Image and Siri AI features don’t ship there yet, which takes two of the reasons to upgrade off the table.

The phones look fine and the timing is bad, so if yours still works, wait a year.
