Apple's iPhone 18 Pro Debuts In-House C2 Modem, But Pro Max Still Uses Qualcomm

Summary · why it matters

Apple's new iPhone 18 Pro features the company's in-house C2 cellular modem, while the U.S. specifications for the iPhone 18 Pro Max do not mention the C2, leaving it unclear which Qualcomm modem is inside the larger model. The C2 supports sub-6GHz and mmWave 5G in the U.S. and Apple says it delivers AI-powered improvements to cellular quality and reliability, faster uploads than the C1X and 15% lower energy consumption. The split could stem from supply constraints, particularly because Apple is using the C2 across the iPhone 18 Pro and iPhone Duo. The development marks another step in Apple's gradual effort to reduce its reliance on Qualcomm, which has supplied cellular modems to Apple for years; Apple began breaking that dependence in 2025 with its first custom modem in the $599 iPhone 16e. Despite missing the C2 in the U.S., the Pro Max gets a major battery advantage, rated for up to 45 hours of video playback versus 36 hours for the Pro, compared with 39 and 33 hours respectively for last year's models. The iPhone 18 Pro starts at $1,199 and the Pro Max at $1,299, with both going up for preorder Sept. 12 and becoming available Sept. 18.

Huang Says Nvidia Chip Units Will Double, Clashing With 70% Revenue Guidance

Jensen Huang said Nvidia expects to sell twice as many chips over the coming year, a forecast that runs ahead of the company's own written guidance. Speaking to reporters at an artificial intelligence gathering convened by King Charles III in Scotland, Huang gave the unit figure, while Nvidia has guided to about 70% revenue growth for the fiscal year ending in January 2028, or roughly $673 billion. If units double while revenue grows 70%, average revenue per chip falls by roughly 15%. Nvidia reported second-quarter revenue of $96.2 billion, up 106% from a year earlier, with data center sales of $89.0 billion and a 75.0% gross margin, and guided third-quarter revenue to $108 billion, plus or minus 2%. The company has said gross margin will decline and bottom out in the fourth quarter of fiscal 2027 at 71% to 72%, partly because of memory prices, a trough that arrives before the unit doubling does. At the same event, King Charles III told executives from Nvidia, OpenAI, Google DeepMind, and Anthropic that the industry needs sufficient means of control before it is too late, and Huang argued that safety belongs to individual companies rather than a coordinated pause.

Marvell and GlobalFoundries Expand SiGe Capacity Deal at Vermont Facility

Marvell Technology and GlobalFoundries have expanded their multi-year agreement to increase production capacity for silicon germanium, or SiGe, at GlobalFoundries' facility in Burlington, Vermont, sending Marvell shares up more than 4% and GlobalFoundries shares up more than 6% on September 17. SiGe is a semiconductor technology used in high-speed optical connections for data centers, allowing devices to operate at higher speeds while using less energy. Robb Johnson, Vice President of Foundry Technology at Marvell, said the expanded collaboration will help ensure the company has the SiGe technology and manufacturing capacity to support the significant growth it expects ahead, and the added capacity will help Marvell meet growing demand for optical networking products including pluggable optical transceivers, near-packaged optics, and co-packaged optics. GlobalFoundries reported $1.786 billion in revenue for the second quarter of 2026, up 6% year over year, with its communications infrastructure and data center segment accounting for about 16% of total revenue and growing 20% sequentially and 62% year over year, and CEO Tim Breen said demand for SiGe remains strong and the company is oversubscribed throughout 2027. Marvell reported record net revenue of $2.739 billion in the second quarter of fiscal 2027, up 37% year over year, and Chairman and CEO Matt Murphy said AI-related bookings remain exceptionally robust as the company raised its revenue outlook for fiscal 2027 and fiscal 2028.

Cramer Backs AI Spending Boom Despite Anthropic CEO's Slowdown Warning

Jim Cramer said on Wednesday, Sept. 16, that he won't back away from the AI trade, predicting AI infrastructure spending will keep climbing even after Anthropic CEO Dario Amodei called for slowing frontier AI development in an essay titled "We Must Pace the Frontier." Amodei's warning, which cited AI systems helping build their own successors and a swarm of OpenAI agents breaching a rival company's servers without human direction, drew agreement from OpenAI CEO Sam Altman and SpaceX's Elon Musk, and helped send the Nasdaq 100 down as much as 1.2% and the semiconductor sector's benchmark index down roughly 5.2%. Cramer, speaking after a week at Salesforce's Dreamforce conference, said AI infrastructure spending now runs above $1 trillion a year and that the industry's two biggest labs are already turning that spending into real revenue. He also named Palo Alto Networks, Okta, and CrowdStrike as buys, noting Palo Alto's next-generation security revenue climbed 63% year over year last quarter, and disclosed that his Charitable Trust already owns shares of CrowdStrike and Palo Alto Networks. Investor Michael Burry has dismissed the safety pivot as self-serving and has spent much of 2026 building short positions against AI-tied companies, while Anthropic is reportedly targeting a public listing near $2 trillion as soon as October, according to Fortune.
