With shares of META moving higher on the potential behind Muse, it's worth noting the big picture; personalized AI subscriptions are an underappreciated AI growth lever. On the consumer side, I estimate only 2% of all daily internet users pay for an advanced model. While this opportunity directly benefits the frontier model companies, it is also a big opportunity for Meta and Apple, which are building personalized AI. For example, by 2030, I see a conservative case in which Apple increases its operating income in that year by 18% and an aggressive case in which it doubles it. For Meta, I see a conservative case of an additional 8% of operating income and an aggressive case in which it adds 80%. While the gap between conservative and aggressive is wide, it's built on a belief that these bots will be valuable to consumers and they'll be willing to pay for the technology. On the enterprise side, the average monthly AI spend per employee in the U.S. is only $13 versus the average software spend of $780, suggesting there's lots of room to grow.

This fall, Apple split the iPhone upgrade cycle into two launches: Pro models and Duo this fall, followed by the iPhone 18, 18e, and Air in the spring. Our tracking shows Pro model pre-order lead times are about 15% longer than a year ago on launch day. Since Duo will cannibalize some Pro demand, the higher lead times suggest that some would-be iPhone 18 buyers are opting for Pro models, offsetting much of the cannibalization. Putting it all together, I think the Street is still 10% too low on iPhone revenue for FY27. We’ll get a clearer read when Duo pre-orders open on October 16.

Shares of AAPL moved about 7% from the end of the “Surprise and Shine” event to close of market today (2.5 trading days), while the Nasdaq was flat. The move higher underscores that investors are optimistic that the new Duo will add a measurable amount to revenue in the coming year. That said, a look at FactSet analysts estimates reveal consensus revenue expectations for the next three quarters actually went down by 1% for analysts that have updated their models. The dynamic of shares of AAPL going higher while numbers are going slightly lower underscores the mixed investors feelings on the Duo topic. In the end, I expect Duo will be more successful than current expectations and account for around 12% of overall iPhone revenue in FY27, and add 3% to the company’s overall growth rates. The biggest disappoint of the event was we didn't get an update on the timing of the new Siri.

I've been dreading this day: Tim's last day as CEO of Apple. In the months leading up to his shift to chairman, I've thought a lot about his time at Apple. In the end, Tim accomplished what almost no one thought was possible. He took Jobs's greatest product, Apple itself, and shepherded it into a new era. In doing so, he drove Apple's market cap from $350B when he took over to $4.6T today. That's up about 2,300% vs. the Nasdaq, up around 900%. All that said, what I most admire about Cook is that despite all of the fortune and fame of becoming the world's most powerful CEO, he kept his North Star and always cared deeply about people. Below are the four things that stand out to me when I think about Cook's legacy.

Shares of NVDA were up about 8% following earnings on management guidance for CY27 revenue growth of at least 70% versus the Street at 45%. When we factor in the impact of higher memory prices, the guide implies the world's collective AI brain will be at least 60% larger next year vs. previous expectations of a 45% increase. Demand for compute continues to run ahead of supply, and Nvidia remains the best proxy for how quickly AI data center capacity is expanding. The one negative was the margin guide, calling for them to move from 45% in the last quarter to 71-72% in the January quarter before improving to 72-73% as price increases flow through in CY27. While margins are going down, I still consider them robust (they were 59% in the pre-AI-boom CY22). Post-earnings, the company announced it has acquired Hugging Face, showing Jensen is building an open-source hedge against hyperscalers that are pushing harder into custom silicon.

Nvidia reports its July quarter results on Wednesday, August 26. I expect them to do what they have done over the past few quarters: beat by 4% and raise revenue guidance for October by 3%. Given that last quarter they began to break out data center growth between hyperscalers and ACIE, the topic of growth rate trends within those segments will be a focus. I believe investors will want to see hyperscaler growth rates above 80% y/y (vs. 115% last quarter) and ACIE above 150% (vs. 74% last quarter). In other words, investors want to see that the growth baton has been handed to ACIE, given that group has more potential to drive long-term growth. The one wildcard, SpaceX, which I estimate accounted for about 4% of revenue in July, has the potential to become a 10% customer by the end of CY27. That means that SpaceX alone can drive hyperscaler capex growth in CY27 to above 68%, compared to the Street, which is currently at 38%. As for the stock, it's in a catch-22. Any upside they produce makes the out-year growth more difficult, a dynamic that mutes any upside to shares.

This week, the new Grok 4.6 moved from 8th to 4th place on the key AI model intelligence leaderboard. That’s noteworthy because over the last couple of years the model has been between 6th and 15th place. The move to 4th is impressive, but in the AI model leapfrog game the future position is debatable. I believe Grok’s trend in model intelligence will continue to improve relative to the competition over the next 6 months, yielding a top spot early in 2027. That’s important because in the long term, premium models will enjoy pricing leverage.
