Daily Tech & GNSS News Digest - May 6, 2026

Wall Street hit fresh records on Wednesday as blockbuster AI earnings from AMD and Super Micro Computer fueled a broad tech rally, while behind the scenes Big Tech continued borrowing at historic pace to bankroll the infrastructure buildout — and in the positioning world, GPS-denied navigation attracted fresh capital as real-world GNSS interference intensified.

AMD and Super Micro Earnings Ignite Semiconductor Rally

Advanced Micro Devices delivered a blowout first quarter, reporting revenue of $10.25 billion — up 38% year-over-year and comfortably ahead of the $9.89 billion Wall Street consensus. Data center revenue hit $5.8 billion, surging 57% year-over-year on strong demand for EPYC processors and Instinct GPU accelerators powering AI inference and agent workloads. CEO Lisa Su said the company has “strong and increasing confidence” in reaching tens of billions in data center AI revenue next year. AMD shares jumped 17.8% on the day.

Super Micro Computer added fuel to the rally, with shares leaping 24.5% after reporting improved gross margins of 9.9% — up from 6.3% in Q2 — and issuing guidance that topped expectations. The AI server maker projected fiscal fourth-quarter revenue of $11 billion to $12.5 billion, signaling that it’s gaining control over the costs of delivering powerful AI servers at scale. Together, the two reports lifted peers across the semiconductor sector, with Nvidia rising 5.5% and Intel gaining 4.2%.

Nvidia Invests $500 Million in Corning for AI Optical Connectivity

Nvidia and Corning announced a multiyear partnership to dramatically expand U.S.-based manufacturing of advanced optical connectivity for AI data centers. The deal includes a $500 million strategic supply agreement and plans to build three manufacturing plants in North Carolina and Texas, creating more than 3,000 jobs. Corning will increase its U.S. optical connectivity manufacturing capacity by 10x and expand fiber production capacity by more than 50%.

The partnership underscores how optical connectivity is becoming a critical bottleneck in scaling AI infrastructure. As data center clusters grow to support ever-larger AI models, the fiber and optical components linking thousands of GPUs together become just as important as the chips themselves. Corning shares surged 14% on the announcement.

Big Tech’s AI Debt Binge Reaches $630 Billion

Technology companies continue issuing bonds at a historic pace to fund AI infrastructure. Alphabet kicked off a six-tranche euro-denominated bond offering on Monday, its longest-dated security maturing in 2063, as part of a broader push that has raised approximately $10.5 billion across euro and Canadian dollar bonds. The Google parent has signaled it could spend up to $190 billion in capital expenditures this year.

Bloomberg reports that Big Tech is expected to spend more than $600 billion on AI in 2026, up from $410 billion in 2025. Meta recently priced a $25 billion bond sale, while UBS analysts project as much as $900 billion in new corporate debt globally this year. Morgan Stanley and JP Morgan estimate the technology sector may need $1.5 trillion in total new debt over the coming years to finance AI and data center construction — though some recent deals are showing signs of investor fatigue, with banks offering larger concessions to attract buyers.

GNSS News

ANELLO Photonics, creator of the Silicon Photonics Optical Gyroscope (SiPhOG), has closed a $25 million Series B-2 round to accelerate production of its GPS-denied navigation systems. The oversubscribed round was led by MESH with participation from Lockheed Martin Ventures, Washington Harbour Partners, and several existing investors.

ANELLO’s silicon-photonics-based inertial navigation technology delivers fiber-optic-class performance in a compact, scalable form factor — providing continuous, high-precision positioning independent of external GNSS signals. The funding will drive broader deployment across autonomous systems operating in contested environments on land, air, and sea. The company previously secured $20 million in Department of Defense APFIT funding and launched its Aerial INS product at CES 2026, positioning it as a key player in the growing market for GNSS-independent navigation.

GNSS Interference Deepens in Strait of Hormuz as Shipping Disruption Continues

Widespread GNSS jamming and spoofing continue to disrupt navigation for commercial shipping in the Strait of Hormuz, with the Joint Maritime Information Centre reporting more than 600 individual disruption events within a single 24-hour period. The interference has affected over 1,650 vessels in the Middle East Gulf, causing AIS anomalies including vessels being falsely located at airports, inland areas, and sensitive infrastructure sites across Iran, Oman, and the UAE.

Unlike typical jamming that clusters signals at a single point, the Hormuz spoofing creates the appearance of vessels moving in straight lines toward the strait — trajectories the ships are not actually following. The UK Maritime Trade Operations advisory now classifies GNSS disruption as a “standing navigational hazard” in the region, and leading war-risk insurers are withdrawing coverage. The crisis underscores the urgency of developing GNSS-independent positioning capabilities for maritime applications.

Key Takeaways

AI earnings are broadening the semiconductor rally: AMD’s 57% data center revenue growth and Super Micro’s margin recovery signal that AI infrastructure demand is expanding beyond Nvidia to lift the entire chip ecosystem.
The AI debt machine is accelerating: With Big Tech expected to spend over $600 billion on AI this year and tapping every global bond market to fund it, the scale of borrowing is entering territory that even credit markets are beginning to question.
GPS-denied navigation is attracting serious capital: ANELLO Photonics’ funding round — backed by Lockheed Martin Ventures and defense money — reflects growing urgency to develop alternatives as real-world GNSS interference in the Strait of Hormuz demonstrates the fragility of satellite-dependent navigation.
