According to Polaris Market Research, the global 800 VDC data center power architecture market was valued at $16.24 billion in 2025 and is projected to reach $59.76 billion by 2034, growing at a 15.6% CAGR from 2026 to 2034. As AI rack power density rises, operators are shifting to higher-voltage direct current to reduce conversion steps, copper use and energy losses. Google, Microsoft and NVIDIA, alongside more than 80 Open Compute Project companies, announced plans in 2026 to standardize 800 VDC specifications. Retrofits of existing facilities accounted for 58.36% of deployments in 2025, while native 800 VDC revenue is expected to begin around 2029. North America led with $6.22 billion in 2025, while Asia Pacific is projected to grow fastest at a 16.7% CAGR.

- SWI Compute Emerges from Stealth to Turn Gigawatts of Power Into NVIDIA AI Factories, Starting in Europe
SWI Compute, which has emerged from stealth, will build and operate NVIDIA AI factories, launching first in Europe. The company is backed by 3.6 gigawatts of power capacity that parent SWI Group, listed on Euronext Amsterdam, spent six years securing across Europe and the US. It became a Preferred NVIDIA Cloud Partner in August, ordered approximately $1 billion of NVIDIA systems, and has finalized contracts with its first customers. Its first large UK AI factory starts with 30 MW, close to 7,000 Rubin GPUs and 3,500 Vera CPUs in Vera Rubin NVL72 racks expected online by the end of 2027, as the first step toward a campus planned to reach 530 MW and 2.3 GW of capacity by 2029. Delta Computers is the systems integrator, and the partners are set to deliver more than 8,000 GPUs.
- 3 AI Infrastructure Stocks Linked To Data Center Power Demand
The article outlines a backdrop of elections in Brazil and Serbia, oil worries tied to the Middle East, and a big week of cloud and AI earnings from Alphabet, Microsoft and Amazon. It profiles three AI infrastructure stocks linked to data center power demand. Monolithic Power Systems, which designs power-management chips, has about US$3.3b in revenue and a US$56.0b market cap, and management expects Enterprise Data growth of at least 130% year over year, with data center exposure approaching 50% of revenue. Analog Devices, with about US$13.9b in revenue and a US$189.5b market cap, reports data center revenue at about 2b on an annualized basis and says its 2030 data center and energy market estimate has more than doubled versus last year. KLA, with a US$190.0b market cap, has a backlog of about US$12.5b and lead times extending into 2027 and 2028.
- Where Will Bloom Energy Stock Be in 5 Years?
Surging power demand from AI data centers is outpacing grid expansion, positioning Bloom Energy as a bridge power provider for hyperscalers, and its stock (BE) has risen 2,085% since November 2024. The company has signed major deals with American Electric Power for up to 1 GW, Oracle for 2.8 GW and Brookfield Asset Management, which expanded to $25 billion. Bloom aims to double its near-term annual capacity to 2 GW and eventually reach 5 GW, backed by nearly $2.7 billion in cash and $175 million in free cash flow at the end of the second quarter. It estimates its 800V DC-native energy server platform could cut non-computer capital expenditures for a 1 GW data center by $3.6 billion, or 27%. However, its backlog stands at $442 million and the stock trades at roughly 40 times forward earnings, leaving it vulnerable to price volatility.
- Some of Amazon’s New AI Servers Are Reportedly Waiting on Power. Here’s What October 29 Has to Prove
According to Business Insider (reported October 20), some Nvidia GB300 server racks Amazon has received are sitting in warehouses because the data centers meant to run them lack power. Citing August internal emails, the report said Amazon expected about $5 billion of racks under an Early Rack Receipt process, plus roughly $3 billion more each month; Amazon disputes that it lacks a deployment plan. The article argues the constraint is power rather than demand, but racks in storage earn nothing, and free cash flow was negative $7.69 billion in the second quarter. Amazon's third-quarter call is at 5:00 p.m. ET on October 29, when investors will look for operating income against a ceiling of $26.5 billion. The main risk the article cites is power: if racks sit idle into 2027, capex will keep running ahead of revenue for longer.
- Caterpillar Is Quietly Becoming an AI Stock. Here's the Segment Growing 72% That Proves It.
Caterpillar's second-quarter revenue rose 24% from a year earlier and earnings per share jumped 73%, with the power and energy segment growing fastest. Retail sales of power generation equipment climbed 72%, which CEO Joseph Creed attributed to very strong demand for large generator sets and turbines used in data centers. Data centers consumed about 4.9% of U.S. electricity supply in 2025, and their consumption is projected to more than double by 2030. The company's backlog reached a record $72 billion, up 92% over the past year. Wall Street expects third-quarter revenue growth of 17% and earnings of $7.03 per share, up 42%, and the author says he wouldn't be surprised if the company beats those estimates.
- I'm Calling It: Bloom Energy Will Be the Biggest Winner of the AI Power Crunch for 1 Reason
The author argues Bloom Energy (BE) will benefit most from AI’s power shortage because its solid oxide fuel cells can bring data centers online in about three months without grid connections, unlike utility hookups that can take years. Bloom crossed $1 billion in revenue in the second quarter, up 166% year over year, and holds about $2.7 billion in cash. Management raised full-year revenue guidance to $3.9 billion–$4.2 billion, nearly double 2025 levels. Shares have risen more than 150% year to date and trade at 357 times trailing earnings, which the author believes is justified by the improving balance sheet and steady demand for fast power.

- Apple (AAPL) vs. MSFT and GOOGL: Is the Post-Earnings Selloff Creating a Long-Term Buying Opportunity?
This article summarizes a bullish thesis on Apple (AAPL) by Natan Rose, published on Research Nuggets' Substack on Aug. 18, when AAPL has since gained 10.92%, reflecting optimism about a stronger iPhone upgrade cycle as early iPhone 18 Pro sales outpace last year's model. Apple reported record revenue of $109.42 billion, up 16%, with iPhone sales up 22% and EPS of $2.02, yet the stock fell 7.35% after earnings as guidance of 9%-11% growth came in below the 12% analysts had hoped for. The article attributes the slowdown mainly to memory chip supply, as DRAM and NAND are increasingly directed to AI data centers, rather than to weaker demand. Risks cited include slower growth with a valuation near 35 times earnings, a CEO transition to John Ternus, and regulatory pressure on App Store fees.
- Russia's diesel output jumps after export curbs are lifted
Russia's daily diesel output rose from 160,000 tonnes in early October to 180,000 tonnes after the government eased export restrictions, allowing companies to ship up to 500,000 tonnes in October. Based on Reuters estimates, a drop in domestic demand after the harvest could free more than 1 million tonnes a month for export. A diesel deal between Presidents Putin and Trump, and a temporary US sanctions waiver for Russian diesel imports, has strained US-Ukraine relations, with Trump urging Zelensky to stop attacks on Russian refineries. Zelensky called Trump's claims “completely false” and argued that the US-Israeli military campaign against Iran and Iran's response had caused severe disruption in the Strait of Hormuz. Russia was previously the world's second-largest diesel exporter, with about 10% of global exports, so supply disruptions could push up prices even in countries that do not import directly.
- 3 Tech Dividend Stocks That Offer Income and Stock Price Growth Through AI
The article highlights three tech stocks whose dividend yields exceed the S&P 500 average of 1.1% while still benefiting from AI demand. IBM pays $6.76 per share a year, a 2.7% yield, has increased its payout for 31 straight years, and generated over $15 billion in free cash flow versus $6.3 billion in dividends, though its third-quarter revenue rose only 5% to $17 billion. Digital Realty, a data center REIT, yields 2.9% on a $4.88 annual dividend, having suspended payout hikes in 2022 to fund expansion, and its revenue rose 29% to $1.9 billion in the first half of 2026. Cisco pays $1.68 per share for a 1.6% yield, while its fiscal fourth-quarter revenue of $17 billion rose 18% as AI infrastructure demand grew. The article suggests these dividends appear sustainable based on the companies' cash flow.
- Should You Buy Amazon Stock Before Oct. 29?
Amazon will report its third-quarter 2026 earnings on Oct. 29, giving investors more insight into whether AWS revenue growth can offset concerns about capital expenditures, which are expected to reach up to $220 billion this year. The article argues that one quarter will not decide the outcome for a $2.7 trillion company, and that Amazon's long-term value lies in AWS and its role as backbone of AI infrastructure, supported by custom Trainium chips. AWS revenue rose 37% last quarter, above Wall Street estimates of 31%. Citing Statista, the article says the global AI market is valued at $707.4 billion in 2026 and could reach $1.96 trillion by 2032. It concludes that Amazon could either beat or miss its upcoming results, and that for long-term investors, multi-year performance matters more than a single earnings report.
- MercadoLibre Cratered by 20% Last Year: Two Wall Street Pros Agree It's Going to Rise 50% Soon
MercadoLibre reported record revenue, with second-quarter revenue up 49.8% to $10.17 billion, but operating margin fell 550 bps to 6.7% and operating income dropped 17% to $683 million as the company spent on lower free-shipping thresholds, credit cards and AI tools. Net debt rose to $6.4 billion from $4.7 billion, and the stock is down 22.78% over the past year. Susquehanna and Barclays have $2,500 price targets, roughly 49.8% above the $1,668.72 share price, citing Mercado Pago's scale, its logistics advantage and advertising revenue that grew 73%. Earnings estimates are sliding, with the 2026 EPS consensus at $38.2807 versus $39.9564 ninety days earlier and 12 downward revisions against 2 upward over the past 30 days. The article says the upside case depends on operating margin recovering from the current 6.7%.
- Why JetBlue Stock Popped This Morning
JetBlue shares fell nearly 10% before its Q3 2026 earnings report amid worries about bankruptcy, but rebounded strongly, rising 13.9% as of 10 a.m. ET, after the results were released. The airline lost $0.60 per share, wider than the $0.53 loss analysts expected, and its $2.8 billion in revenue also fell short of forecasts, although operating revenue rose 21%. Expenses rose 19.4%, with jet fuel costs up 57% a major pressure; without that cost, expenses would have been up only 7%. Management expects revenue to keep growing into 2027 and margins to expand in Q4 despite fuel prices forecast to be 85% higher, and targets profitability and positive free cash flow again by 2028, with at least $1 per share in earnings.
