Now, listen closely. Most of this Artificial Intelligence business – all the brainy thinking machines – happens inside colossal, echoing halls. These aren’t cozy little studies, mind you, but enormous data centers, crammed to the rafters with thousands of what they call ‘Graphics Processing Units’ – or GPUs, for short. Nvidia and Advanced Micro Devices are the usual suspects, the big cheese suppliers of these GPU contraptions. But lurking in the shadows, a rather clever fellow named Broadcom is also peddling ‘AI accelerators’ – fancy chips that give the machines a bit of extra oomph.
But it’s not just about the chips, see. It’s about getting the messages whizzing back and forth, faster than a greased whippet. And that’s where Corning comes in. They’ve become the top dogs in supplying these marvelous things called fiber-optic cables. These aren’t your grandpa’s copper wires, oh no. These cables transmit data at a speed that would make a cheetah blush. Speed is absolutely vital in this AI race, so these data center operators are snapping up Corning’s fiber like hungry badgers. It’s causing a glorious, rumbling surge in their revenue, you see.
Corning’s stock price has shot up, a proper rocket, by a whopping 170% in the last twelve months. It’s utterly squashing Nvidia, AMD, and Broadcom, which are plodding along with mere gains of 61%, 94%, and 84% respectively. And here’s the delicious bit: there’s a good chance it’s going to keep on climbing. Let me explain.
These Data Centers are Going Fiber-Mad
Nvidia’s fancy Blackwell GPUs are often crammed into these ‘NV-Link racks’. Each rack is a beast, usually holding 72 GPUs, plus 36 of those central processing units (CPUs) and a whole heap of networking bits and bobs. Now, each of these racks used to be connected with two miles of copper cable. Can you imagine the tangle? But these clever data center folks are switching to fiber, and that’s a golden opportunity for Corning. A truly golden opportunity.
Fiber, you see, is proven to send information at speeds that copper can only dream of, and over much, much longer distances, with hardly any loss of signal. Many of these AI developers pay for cloud computing by the minute, so faster speeds mean substantial savings. It’s simple arithmetic, really. And a very pleasing one for those who invest wisely.
And here’s the kicker. Right now, 72-GPU racks are the standard, but eventually, every rack will be stuffed with hundreds of GPUs. Think of the chaos! So, the efficient transmission of data will become even more crucial. That’s why Meta – the folks behind Facebook – just secured their future supply of fiber. They signed a deal with Corning in January to purchase a staggering $6 billion worth of cables over the next few years. A truly enormous sum, wouldn’t you agree?
But this is only the beginning, my friend. Corning’s CEO, a rather shrewd fellow named Wendell Weeks, predicts that the market for data center optical fiber could triple in size, all thanks to the insatiable appetite of these AI developers. Triple! Now, that’s what I call a tasty prospect.
Corning’s Revenue is Practically Exploding
Corning churned out $16.4 billion in core revenue during 2025, a 13% jump from the year before. Their optical communications business contributed $6.2 billion of that, growing at a positively giddy pace of 35%.
The enterprise segment of the optical communications business, specifically, delivered $3 billion in revenue – a whopping 61% increase! The amount of revenue from these ‘hyperscaler’ customers – the big boys – more than doubled. It truly highlights the desperate demand for data center optical fiber right now. These folks are practically begging for it.
That demand grants Corning a significant amount of pricing power, resulting in a record $1 billion profit for their optical communications business alone during 2025 – up 71% from the previous year! It contributed to core (adjusted) earnings of $2.52 per share for the company overall. A very satisfying number, indeed.
Corning Stock Isn’t Cheap, But It Might Be Worth a Nibble
Based on Corning’s 2025 earnings, the stock is trading at a price-to-earnings (P/E) ratio of 48.9. A hefty premium, you say? Yes, it’s a bit pricey compared to the 31.8 P/E ratio of the Nasdaq-100 index. It looks rather expensive compared to a basket of other tech companies.
Corning is also more expensive than Nvidia, which is trading at a P/E ratio of 37.3. However, it trades closer to the P/E ratios of AMD and Broadcom, which currently stand at 46.1 and 45.5, respectively.
While it’s reasonable to argue that Corning stock is fully valued right now, there might still be some upside for investors willing to hold on for a couple of years. Wall Street’s estimates suggest that earnings will grow to $3.11 per share in 2026, and then to $3.87 per share in 2027, placing the stock at forward P/E ratios of 39.6 and 31.8, respectively.
Plus, Weeks says that Corning is finalizing several other agreements similar in size and scope to its recent Meta deal, so analysts might have to raise their earnings forecasts when more information becomes available. In other words, Corning stock might actually be cheaper than it appears. A clever illusion, wouldn’t you say?
