Serenity focuses on floating AI data centers: Samsung Heavy Industries aims for commercial deployment by 2028, with free seawater cooling to solve power and land bottlenecks.
According to Mars Finance, on July 4th, Serenity stated that floating AI data centers and ocean computing already exist, with their core advantage being significant energy savings through natural seawater cooling. This is particularly beneficial for areas with limited land resources, similar to the concept of "orbital computing." Samsung Heavy Industries plans to launch its first commercial floating AI data center, approximately 50MW, in 2028, while Singapore's Keppel is also advancing a similar project, expected to be operational that same year. Serenity also noted that Microsoft previously explored submerged data centers under Project Natick, but this has since been terminated; this is not the same concept as the currently discussed floating data centers. This addresses two major pain points in AI infrastructure: power and cooling. Furthermore, its modular and mobile characteristics are naturally suited to areas with scarce land.
SpaceX's Colossus data center faces shutdown order, putting a $45 billion deal at risk.
According to Odaily sources, a lawsuit is seeking a court order for SpaceX to shut down the gas turbines powering its Colossus 2 data center, arguing that they are operating without the necessary permits. This lawsuit could jeopardize parts of SpaceX's $45 billion contract with Anthropic. A lower court will likely order the turbines to be shut down while permits are being obtained, but may also grant SpaceX some time to comply with the regulations.
U.S. tech giants' data center leasing commitments hit a record high of $850 billion.
According to BlockBeats, on July 5th, US tech companies committed a record $850 billion to data center leasing, an increase of $570 billion (+204%) year-over-year and $200 billion (+31%) quarter-over-quarter. Meta added approximately $79 billion in data center leasing commitments in Q1 2026, a 76% increase quarter-over-quarter, bringing its total commitments to approximately $183 billion; Microsoft added approximately $41 billion, a 26% increase quarter-over-quarter, bringing its total to approximately $197 billion; Oracle leads with approximately $250 billion in total commitments and has secured key data center resources for its partnership with OpenAI. This reflects that demand for AI infrastructure is entering a long-term structural growth phase, and supporting industries such as semiconductors, energy, and liquid cooling are expected to continue to benefit. At the same time, the increased demand for computing power may further exacerbate GPU supply shortages, providing support for the valuation of AI concepts and related tokens. --------------------------------- Click the original link below to join the Beating · Lark AI news channel and monitor global AI hot topics and news 24/7.
Global AI data centers face the threat of extreme heat.
Mars Finance reports that with heatwaves sweeping across many countries, major global technology companies are facing a severe challenge: ensuring the continuous and stable operation of high-performance chips within their AI data centers. The report cites recent research data from a climate risk analysis agency, stating that up to 79% of the computing capacity of global data centers is currently threatened by various sudden weather disasters, including floods, extreme winds, and wildfires. These disasters could lead to operational disruptions, increased downtime, and higher insurance and maintenance costs. Currently, major technology companies are recognizing the challenges that climate factors pose to the operation of AI data centers and are exploring solutions. Microsoft stated that it is managing the risks posed by extreme temperatures and severe weather through site selection, improving redundancy systems, and real-time monitoring. Nvidia announced last week that its new AI servers can operate in coolant environments up to 45 degrees Celsius. Nvidia claims that a 1-degree Celsius increase in coolant temperature can reduce cooling system energy consumption by approximately 4%. (CCTV Finance)
US infrastructure company MasTec invests another $1.65 billion to strengthen its data center electrical footprint.
Mars Finance reports that US infrastructure engineering and construction company MasTec announced on Tuesday that it will acquire electrical contractor The Superior Group for approximately $1.65 billion to enhance its electrical service capabilities in the rapidly expanding data center infrastructure market. The transaction, conducted in cash and stock, is expected to close in mid-to-late July. (Cailian Press)
Analysis: The AI investment boom is cooling down, and the market is reassessing the sustainability of chip and data center spending.
According to Odaily Odaily, the AI infrastructure investment boom is cooling down, and the market is beginning to reassess the sustainability of chip and data center spending. As investors re-examine whether AI infrastructure investment can be sustained, "AI deals" covering the semiconductor, memory chip, and data center industry chain are showing signs of cooling. Recently, AI-related chip stocks such as Micron Technology (MU) and SanDisk (SNDK) have been under pressure. Samsung Electronics previously reported record second-quarter results, but revenue fell short of market expectations, causing its stock price to drop nearly 7%, dragging down the entire AI chip sector. Market concerns are growing that the current AI boom, driven by GPUs, high-bandwidth memory (HBM), and data center construction, may face repricing as cloud computing giants (Hyperscalers) may slow their investments in AI infrastructure. Meanwhile, South Korean memory chip giant SK Hynix's stock price has fallen about 25% from its all-time high ahead of its US IPO, which is also attracting some funds away from existing chip stocks. Analysts point out that after SpaceX's massive IPO boosted valuations of AI-related assets, investors are reassessing the growth logic for the next phase of the AI market. If the AI investment fervor cools further, some funds may flow back from the AI industry chain to other risky assets, including crypto assets. (CoinDesk)
