Foxconn crossed a line this quarter that it will not cross back. Its cloud and networking division, the one that builds AI servers, made up 51% of revenue in the three months to June.

That is the first time the segment has passed half. Smart consumer electronics, the division that contains the iPhone, came to 29%.

The profits followed. Net profit reached NT$59.97bn, about $1.86bn, up 35% on a year earlier and the company’s highest ever for a second quarter.

The quarter in numbers

Consolidated sales hit NT$2.53 trillion, up 41% year on year and 19% on the previous quarter. Analyst forecasts were beaten on both profit and revenue.

The cloud and networking share climbed fast. It was 48% in the first quarter, with computing at 15% and electronic components at 5%, per Taiwan’s Central News Agency.

Earnings per share came in at NT$4.27, against NT$3.19 a year earlier. First-half profit reached NT$109.89bn, up 27%.

July was bigger still. Revenue that month jumped 54.2% to a record NT$946.5bn, Bloomberg reported.

What the company is promising

Rotating chief executive Michael Chiang framed the shift as structural rather than cyclical. Cloud investment, he told analysts, “will become the most critical growth driver for Hon Hai over the next few years”.

He drew a distinction that matters for a contract manufacturer. AI infrastructure demand is steady, unlike consumer electronics, which lives and dies by seasonal cycles.

He also argued the buildout has barely started. Cloud providers and AI labs are the big buyers so far, while government and corporate adoption remains, in his words, in its infancy.

The next platform is the near-term test. Nvidia’s Vera Rubin racks enter mass-production preparation this quarter and ship in the fourth, and Chiang expects it to become Foxconn’s major product next year.

The share that is shrinking

Here is the part the headline profit hides. Foxconn is winning a bigger market and losing position inside it.

Morgan Stanley expects its high-end rack market share to fall to 39% this year, from 51% in 2025, according to the Wall Street Journal. Analysts put that down to buyers seeking alternative suppliers rather than to any drop in output.

That diversification is visible everywhere. Microsoft is ordering hundreds of thousands of its own chips from TSMC, and every hyperscaler is doing some version of the same thing.

Analysts have a second worry. As AI server designs standardise, the hardware risks becoming a commodity, which lowers the barrier for rival assemblers.

Chiang rejected that reading outright. Standardisation, he said, “highlights the advantages of suppliers with scaled delivery and complete vertical integration”.

Record revenue, thinner margin

The margin line is the quiet counterweight. Gross margin was 6.12%, down 0.21 percentage points on a year earlier.

Operating margin did improve, to 3.75%, up 0.60 points. Net margin sat at 2.37%, slightly below last year.

So the mix has changed but the economics have not. Assembling servers is still a business measured in single-digit gross margins, and volume is what pays for it.

That is why the capacity plan is so large. Foxconn is expanding to hundreds of sites across 24 countries, close to double its earlier footprint, with new capacity in California, Texas, Wisconsin and Ohio.

The ceiling nobody at Foxconn controls

Chiang named the real constraint on 2027, and it is not demand. It is CoWoS, the advanced packaging technology from TSMC that AI chips depend on.

The market expects that capacity to grow by more than 50% next year. How much of it turns into rack shipments, Chiang said, “will depend on chip supply”.

Foxconn does not control that supply. Neither does Nvidia, which is why the bottleneck keeps moving up the chain rather than disappearing.

The iPhone half of the business has its own geography problem. Most iPhones are still assembled in China, though the bulk of those sold in America are now made in India.

The market is not applauding

Investors have seen these numbers and shrugged. Foxconn shares are up 17% this year, against a 57% gain for the broader Taiwan index.

The doubt is not about this quarter. It is about who pays for the next one, and Alphabet, Meta, Microsoft and Amazon have now committed close to $2.4 trillion to AI over the coming years.

Some of that is borrowed. Alphabet sold $25bn of bonds to help fund its build, and Nvidia has assembled a $500bn package with Wall Street to finance customers who cannot pay upfront.

A tech rout in July was the market rehearsing that worry. One Federal Reserve official has asked whether AI is becoming too big to fail.

Foxconn has answered the only question it can. It has proved the demand is real, that it can build to meet it, and that doing so has quietly turned an iPhone company into an AI infrastructure company. What it cannot prove is that the people writing the cheques will keep writing them.
