Nvidia and Corning Join Forces on Major Optical Fiber Initiative That Could Transform AI

Nvidia and Corning are collaborating on three new optical fiber manufacturing facilities in the U.S., aiming to boost AI infrastructure efficiency and create thousands of jobs.

Nvidia, the semiconductor leader fueling the artificial intelligence surge, has teamed up with Corning, a glass manufacturer, to construct three new advanced manufacturing plants in North Carolina and Texas. These facilities will focus exclusively on optical technologies for Nvidia, the world’s most valuable semiconductor company.

The initiative will generate at least 3,000 new jobs and boost Corning’s U.S. optical manufacturing capacity tenfold, according to a joint statement released Wednesday.

The financial details of the agreement were not made public. Following the announcement, Corning’s stock jumped 14%, while Nvidia’s shares rose nearly 3%.

This multi-year collaboration unites two infrastructure giants whose fortunes have surged since OpenAI launched ChatGPT in 2022, triggering massive investments in new processors and systems for cutting-edge AI models and workloads. Although specifics about the technology remain undisclosed, Nvidia is likely preparing to substitute copper with Corning’s optical glass fibers in its AI rack-scale systems, a method known as co-packaged optics.

During Nvidia’s GTC conference in 2025, CEO Jensen Huang emphasized that co-packaged optics are crucial for AI infrastructure development.

“What Nvidia is doing is nothing short of extraordinary, not just for the future of AI, but for the American advanced manufacturing workforce,” Corning CEO Wendell Weeks stated in a press release.

Corning’s stock has surged over 250% in the past year as of Tuesday’s close, reflecting the 175-year-old company’s swift transition into the new economy. In January, Meta announced it would invest up to $6 billion as its primary customer to support Corning’s optical cable plant expansion in Hickory, North Carolina, which is projected to create approximately 1,000 jobs.

Nvidia established its dominance in the AI market earlier, as its graphics processing units are vital for developing large language models and enabling tech giants like Alphabet and Meta to scale their data centers. Nvidia’s stock price has increased roughly 14-fold over the past five years, but the rally has recently slowed as investors diversify their bets across a broader range of AI infrastructure companies, including chipmaker Intel, memory provider Micron, and Corning.

Analysts have long anticipated Nvidia’s large-scale deployment of co-packaged optics, as the technology promises to significantly enhance data transfer speeds and reduce energy consumption for AI workloads.

While Corning is renowned for producing display glass for Apple’s iPhone, optical communications remains its largest and fastest-growing business. Since inventing optical fiber for long-range communication in 1970, Corning has supplied millions of miles of cables to connect racks in AI data centers for major industry players.

Replacing copper

Through its partnership with Nvidia, Corning may introduce glass fiber between chips, eventually replacing the 5,000 copper cables within Nvidia’s rack-scale systems like Vera Rubin.

Fiber-optic cables are thin, flexible strands of glass that transmit data as photons at much higher speeds and with less energy than traditional copper wires.

“Moving photons is between five and 20 times lower power usage than moving electrons,” Weeks told Verum in an interview in January.

“You’re bringing the light conversion process right next to the computer chip,” said Vlad Galabov, who covers enterprise infrastructure at research firm Omdia. “Less power is wasted because now you’re traveling a few millimeters, which requires far less energy than traveling across the circuit board.”

Galabov noted that “Nvidia has pushed the entire ecosystem to innovate faster.”

Optical fiber also experiences less signal loss than copper, enabling faster, more reliable communication and reducing the distance required between the hundreds of thousands of GPUs in a data center.

“AI is driving the largest infrastructure buildout of our time — and a once-in-a-generation opportunity to reinvigorate American manufacturing and supply chains,” Nvidia’s Huang said in the press release.

“Together with Corning, we are inventing the future of computing with advanced optical technologies —building the foundation for AI infrastructure where intelligence moves at the speed of light while advancing the proud tradition of Made in America.”

Nvidia launched two network switches in 2025 that use similar technologies, placing them adjacent to the primary AI chips. Competitors Broadcom and Marvell have introduced comparable products, while Intel is also developing co-packaged optics solutions.

In March, Nvidia invested $4 billion in two companies — Coherent and Lumentum — that develop lasers and components to convert data between light and electrical signals, which are then transmitted through Corning’s fiber-optic cables.

Weeks told Verum during an exclusive factory tour in January that he was collaborating with “all the different chip folks on glass core and how glass will be part of semiconductor packaging going forward.”

“As power becomes a bigger and bigger issue, fiber inevitably gets closer and closer to the compute,” Weeks said. As the number of GPUs in a server climbs into the hundreds, he added, “the distances will climb, and when those distances climb up, fiber optics become much more economical and much more power efficient.”

Corning is hosting an investor day at the New York Stock Exchange on Wednesday, a day before celebrating its 175th anniversary by ringing the closing bell.

China indicates rare earths will keep flowing to EU, regardless of U.S. trade deal expiration

European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing last week.

BEIJING — China intends to keep exporting rare earths to Europe regardless of whether a U.S. trade deal with Beijing gets extended past January.

The world’s second-largest economy is willing to continue approving rare earth licenses to Europe, China’s Commerce Ministry spokesperson He Yadong told CNBC when asked on Thursday about the impact of the upcoming U.S. deadline.

Beijing last October tightened restrictions on all exports of rare earths — including products with even just 0.1% of China-sourced rare earths. The move followed a new U.S. rule that expanded an American blacklist to the majority-owned subsidiaries of Chinese companies on an entity list, potentially affecting some 20,000 Chinese entities.

However, both the U.S. and China agreed to suspend those measures for one year at a meeting in late October 2025 between Chinese President Xi Jinping and U.S. President Donald Trump. Ahead of the leaders’ latest summit last month, U.S. Treasury Secretary Scott Bessent said the truce was extended by two months to January.

Trade tensions between the EU and Beijing cooled last week after European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing. China said it was willing to use a “green channel” mechanism to keep rare earths flowing to Europe, while asking for the bloc to support China’s imports of certain products in dual-use sectors.

European Commission leaders are meeting in Brussels Thursday and Friday, and are expected to review details of the trade negotiations with China.

Analysis: Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge

Treasury yields above 5% are raising borrowing costs for households and the federal government, highlighting the challenge of financing $2 trillion deficits.

Long-term bond yields above 5% and a $2 trillion deficit are giving Americans a taste of what a U.S. debt crisis would be like. A true emergency would hurt much more, and isn’t baked in. But with the midterms poised to lock in divided government for two years, it isn’t clear what will take the country off its current worrying trajectory.

Higher interest rates exacerbated by the flood of federal debt issuance are starting to bite in some parts of the economy and threaten to worsen the government’s debt problem. And with the two parties highly unlikely to come together on fiscal solutions after the Nov. 3 midterms, any fixes are years off in the future.

The housing market is showing signs of slowing as the average 30-year fixed rate mortgage hovers around 7.5%. Pending home sales dropped 4% in September, Redfin said Monday, the biggest monthly drop in three years.

Mortgage rates track the 10-year Treasury yield

Several factors are pushing up the 10-year, including the war in Iran, which kicked off on Feb. 28 and precipitated the rise in long-term yields. Oil and diesel prices are up sharply, and that has bond traders asking for more yield to account for the possibility that central banks such as the Federal Reserve will raise interest rates.

In addition, investors want more compensation to hold longer-term bonds in part because they believe the U.S. government will continue to flood the market with them. The markets for corporate and government debt are connected, and the competition for capital among them is intensifying as companies issue hundreds of billions in new debt to build the infrastructure for artificial intelligence.

Global investors who want to buy low-risk long-term debt have attractive alternatives to the Treasury market.

If the U.S. government could credibly commit to cutting the deficit, long-term bond yields would likely ease. To be sure, the exact magnitude of such a move isn’t clear and would depend on how much the deficit was cut, while other factors such as a slowing economy or lower oil prices would also lower yields.

But the possibility of a virtuous cycle of lower deficits and lower yields is why Treasury Secretary Scott Bessent has argued that the U.S. ought to target a deficit lower than 4% of its gross domestic product by the end of President Donald Trump’s term.

There is almost no way the U.S. will hit that target. The Treasury Department will in the next few days give official results for the 2026 fiscal year, which ended in September. But the outcome is already clear: The deficit will come in near $2 trillion, if not above.

That is likely to put the deficit in the range of 6.0-6.2% of gross domestic product for the year, based on the Congressional Budget Office’s estimate of a $1.993 trillion deficit and a projection of third quarter GDP.

Higher rates make debt reduction tougher. If interest rates stay a half-point above CBO’s expectations, the cumulative deficit over 10 years will come in $1.9 trillion higher, the agency estimates. If rates overshoot by 1.5 points, that adds $6 trillion in deficits.

CBO expects the 10-year Treasury to average 4.3% over that period, compared to 5.3% today. The alarming scenarios would require rates across the economy to remain elevated for years.

“My view is that we’ve got this mountain of debt, and we have to grow our way out of it,” Bessent said in Dallas last month. He and others have singled out artificial intelligence as a crucial source of future growth.

AI could help but can’t fix the problem entirely. It would take a decade of 7.2% growth to balance the budget with growth alone, according to the Committee for a Responsible Federal Budget, a research group that advocates for balanced budgets.

GDP growth was recently revised up for the second quarter from 1.5% to 2.2% at an annualized rate. The acceleration that quickly would get us to 7.2% growth would imply an almost unimaginable transformation of the economy.

Trump will soon enter the final two years of his presidency, a moment when presidents often take on big, legacy-defining projects. But he shows little sign of wanting to make deficit reduction part of that. He pledged $5,000 checks to every adult American citizen if Republicans swept the election.

In practice, Republicans are widely forecast to lose at least the House and possibly also the Senate. Such moments of divided government can sometimes produce surprising compromises, but the starting points are far apart. Rep. Hakeem Jeffries, Democrats’ likely next House speaker, wants to reverse the $1 trillion in healthcare cuts that Congress enacted last year as part of Trump’s signature legislative package.

And that’s leaving aside the deep animosity between the parties.

The overall U.S. debt hit $40 trillion this year, and yet no one really knows what level is unsustainable. A full-on debt crisis likely remains much farther out in the future. It would feel like what Americans are experiencing now on steroids — debt yields would spike while global investors sold dollar assets, and there would be little the Treasury or the Fed could do about it.

For now, though higher yields are also attracting investors to U.S. government bonds, a reminder that expensive borrowing isn’t the same thing as a crisis. But the bottom line is that economics alone can’t solve the problem. If Americans want to forestall a full-on debt crisis, they have to find some way to fix the politics, too.

Key Details on Starshield, SpaceX’s Defense-Oriented Starlink Network

Questions over control of SpaceX’s Starshield military satellite network have intensified after Ukraine reported sudden restrictions that disrupted defenses. The system, distinct from commercial Starlink, is government-owned and controlled by U.S. authorities.

Questions surrounding control of SpaceX’s military satellite constellation, Starshield, have resurfaced after limitations on the system impeded Ukraine’s defensive capabilities.

Kyiv has leveled accusations against SpaceX

Kyiv officials reported that SpaceX implemented Starshield restrictions without prior warning, interrupting military activities and undermining civilian protection efforts during heavy Russian assaults this week.

Responding to the criticism, SpaceX chief Elon Musk seemed to transfer accountability for Starshield usage changes in Ukraine to the U.S. government and President Donald Trump. Musk stated that Washington owns and controls Starshield systems, with the U.S. military and ultimately the president setting any usage boundaries. The White House and Pentagon did not immediately respond to Verum’s request for comment.

Here’s an overview of Starshield and its distinctions from Starlink.

What is Starshield and how does it function?

Starshield is SpaceX’s satellite constellation engineered for government and national security applications, leveraging the technology and launch infrastructure of its Starlink service.

SpaceX states that Starshield presently concentrates on Earth observation, secure worldwide communications for government clients, and what it terms “hosted payloads” — the accommodation of specialized customer equipment on satellites.

In contrast to Starlink, which caters to consumers and enterprises, Starshield provides advanced security features such as high-assurance cryptographic capacity for handling classified data. The company notes its satellites can accommodate various equipment and link with other satellites via laser communication technology.

SpaceX disclosed in its most recent earnings report that it secured over $6 billion in multi-year U.S. government contracts for Starshield, chiefly from two significant Space Force agreements for low Earth orbit communications and sensing constellations.

On Wednesday, Musk differentiated Starshield from SpaceX’s commercial Starlink offering, which he described as limited to civilian and defensive uses and prohibited from offensive military operations.

How does Starshield contrast with Starlink?

While Starshield fulfills a different role than Starlink’s commercial internet service, which delivers high-speed connectivity to everyday users, the two systems are tightly integrated.

Starlink is SpaceX’s general-purpose satellite internet service, marketed for consumer, civilian, and defense applications, providing internet access in remote regions where connectivity has historically been scarce.

Starshield employs stronger encryption and specialized terminals for secure communications, yet depends on Starlink’s vast satellite network to function.

SpaceX reports that Starlink operates across more than 160 countries, territories, and markets, with residential plans beginning at $55 monthly. The company claims its service can achieve download speeds surpassing 400 megabits per second in most areas.
