Summary · why it matters

Iridium Communications announced that Mlink Technology has begun live, on-air testing of its MS150-IR IoT-NTN chipset using the Iridium NTN Direct service. The MS150-IR is a specialized version of Mlink's MS150 chipset family developed for Iridium's 3GPP standards-based non-terrestrial network, and the companies expect certification and product availability before the end of 2026. Mlink joins a growing ecosystem of chipset providers supporting Iridium NTN Direct, which leverages Iridium's 66 cross-linked low Earth orbit satellites to deliver global NB-IoT and device-to-device connectivity for IoT applications such as asset tracking, logistics, and industrial monitoring. The successful transition from lab testing to live on-orbit validation demonstrates the technical readiness of the service, according to Iridium Executive Vice President Tim Last. Mlink Co-Founder and Vice President Zhiping An noted that the company has also introduced a comprehensive reference design kit to help customers accelerate product development.

US Hyperscalers to Spend Up to $725 Billion on AI Infrastructure in 2026

The top five US hyperscalers are projecting a combined capital expenditure of $660 billion to $725 billion for 2026, nearly double their 2025 outlays, as the AI build-out shifts from software to physical infrastructure. Microsoft is guiding for roughly $175 billion in adjusted capital expenditure for both FY2026 and FY2027, with two-thirds of quarterly spend going to short-lived assets like CPUs and GPUs and the rest to long-lived data center infrastructure, and it added 1 gigawatt of capacity in Q3 FY2026, doubling its global footprint in two years. Amazon AWS has raised its 2026 capex guidance to approximately $220 billion, with CEO Andy Jassy saying AI capacity is expected to remain constrained through 2027 and contracted demand extending into 2028. Meta saw profit drop 14% in Q2 2026 despite a 28% revenue increase as its build-out, including a 1 gigawatt data center in Ohio and a Louisiana facility that could scale to 5 gigawatts, compressed margins, while Alphabet raised its 2026 capex guidance to as much as $205 billion and its Google Cloud backlog more than doubled year-over-year to $240 billion. The Stargate joint venture involving Oracle, OpenAI and others targets up to $500 billion in infrastructure investment by 2029, and Oracle's FY2026 capex reached $55.7 billion, more than doubling from the previous year.

Citi: Data Center Opposition Has Not Weakened AI Construction Pipeline

Citi says growing political opposition to artificial intelligence infrastructure ahead of the November U.S. midterm elections has not materially weakened the data center construction pipeline. Data center development has become a bipartisan flashpoint, with local governments introducing moratoriums and at least 15 state legislatures proposing tighter regulatory restrictions, yet spending remains strong as AI infrastructure demand continues to support development. The impact has been concentrated among speculative and early-stage projects, which are increasingly delayed or cancelled during local approval processes, while late-stage developments that have already secured sites and grid connections continue to move ahead. Hyperscalers are seeking workarounds to power constraints and local restrictions, with Amazon pursuing direct investment in nuclear development with Dominion Energy and Meta securing a major nuclear power purchase agreement with Constellation Energy. Citi does not expect another market shock comparable to the emergence of DeepSeek, arguing investors have already adjusted to the prospect of highly efficient Chinese models, though it flags a potentially greater risk from governments restricting models deemed too dangerous, which could abruptly create excess computing capacity.

Suppajee Meets Indian Envoy, Pushes Co-Creation and Studies Baht-Rupee Use

Suppajee Suthamphan, Deputy Prime Minister and Minister of Commerce, disclosed the outcome of talks with the Ambassador of the Republic of India to Thailand, Puneet Agrawal, that Thailand and India will advance cooperation in a "Co-Creation Co-Investment" format across six potential sectors: herbs and pharmaceuticals, IT, processed food, green industry, automotive, construction, and the hospitality industry, in order to link into global supply chains rather than merely exporting goods to each other's markets. Both sides assigned the start of joint work and progress within 45 days to pilot a model. Most recently, five to six Thai investors have shown interest in cooperating with India under this concept, and the Indian Ambassador reported that Indian companies are preparing to invest in data centers in Thailand, with several already in joint ventures with Thai companies. Both sides agreed to use the JTC platform as a mechanism to monitor cooperation, with India proposing that the JTC meeting draw up a Plan of Action for the services sector. The two sides are in the process of linking India's UPI payment system with Thailand's PromptPay, and are discussing the possibility of using local currencies, the baht and the rupee, to facilitate trade and reduce costs. India is Thailand's seventh-largest trading partner in the world and its number one trading partner in South Asia. Over the seven months from January to July 2026, trade between Thailand and India was worth 13.97456 billion US dollars, expanding 8.07 percent from the same period the previous year, with Thailand exporting 10.27032 billion US dollars to India and importing 3.70424 billion US dollars from India.
