Microsoft Stock (MSFT) After Hours Today (Dec. 18, 2025): What’s Driving the Move and What to Watch Before Friday’s Open

Microsoft Corp. (NASDAQ: MSFT) ended Thursday’s session higher and is seeing only modest movement in extended trading—an important signal that, as of late Thursday, investors are mostly reacting to macro and AI-theme developments rather than a single company-specific shock headline. As of around 4:29 p.m. ET, MSFT was $482.90 in after-hours trading, down about 0.2% from its regular-session close of $483.98. Below is what mattered for Microsoft stock after the bell on Dec. 18, 2025, and what to keep on your radar before the market opens Friday, Dec. 19, 2025—including a heavy slate of inflation and consumer data that can

AI Stocks Today (Dec. 18, 2025): Nvidia, Microsoft, Broadcom and Micron Rebound as Inflation Cools and OpenAI’s Mega-Round Talk Raises the Stakes

AI Stocks Today (Dec. 18, 2025): Nvidia, Microsoft, Broadcom and Micron Rebound as Inflation Cools and OpenAI’s Mega-Round Talk Raises the Stakes

Updated: Dec. 18, 2025 (4:15 PM EST) AI stocks ended Thursday with a sharp rebound after a bruising stretch that revived “AI bubble” fears across semiconductors and mega-cap tech. The day’s tone shift was driven by two things investors care about most right now: a cooler-than-expected inflation update (supportive for growth-stock valuations) and a blockbuster outlook from Micron that reinforced a simple message—AI infrastructure spending is still accelerating, and the supply chain is still tight. TradingView+2Reuters+2 By the close, Wall Street’s tech-heavy leadership reasserted itself. The S&P 500 rose 0.78% to 6,773.91, the Nasdaq Composite gained 1.37% to 23,004.92, and

AI Stocks Today (Dec. 18, 2025): Micron Ignites the AI Chip Rally as OpenAI Funding Talk and Data-Center Financing Fears Keep Wall Street on Edge

Updated: 1:59 p.m. ET, Thursday, December 18, 2025 AI stocks are rebounding sharply midday Thursday after a bruising bout of “AI trade” volatility earlier this week. The catalyst is familiar: hard evidence of demand. Micron’s blowout outlook and comments around high-bandwidth memory (HBM) have steadied sentiment across semiconductors and mega-cap tech—just as markets digest softer U.S. inflation data, renewed debate over debt-funded data-center expansion, and a fresh jolt from private-market headlines around OpenAI’s next fundraising ambitions.

Top AI Stocks to Buy Today (Dec. 18, 2025): Nvidia, Microsoft, Amazon, Broadcom, Micron and More as AI Trade Rebounds

NEW YORK — December 18, 2025 (12:00 p.m. ET) — After a bruising few sessions driven by data-center financing jitters, the AI trade is finding its footing again at midday. A cooler-than-expected inflation read helped lift rate-cut hopes, while Micron’s blockbuster outlook for AI-linked memory demand reignited risk appetite across semiconductors and the broader tech complex. Reuters+1 That rebound doesn’t erase the market’s big new question: can the industry keep funding a trillion-dollar buildout of chips, power, and data centers long enough for profits to catch up? Oracle’s financing headlines and the sudden repricing in “AI infrastructure” names show how quickly sentiment can swing—even

Big Tech Stocks Today: Magnificent Seven Rally Near Noon ET as Soft Inflation and AI Demand Reset the Narrative

Big Tech stocks are back in control of the tape around 12:00 p.m. ET on Thursday, December 18, 2025, with investors leaning into a familiar late-cycle trade: cooler inflation → lower yields → higher-growth tech. After Wednesday’s sharp pullback on renewed “AI bubble” chatter, the Magnificent Seven are broadly higher in midday trading, helped by a one-two catalyst punch: a benign inflation print (with important caveats tied to the recent U.S. government shutdown) and a fresh confirmation of AI hardware demand after Micron’s blowout results and guidance.

Three Mile Island Restart: Energy Secretary Chris Wright Says Crane Clean Energy Center Can Cut Power Prices and Fuel Microsoft’s AI Push

LONDONDERRY TOWNSHIP, Pa. (Dec. 18, 2025) — The U.S. Energy Secretary is betting that one of the most symbolically loaded names in American energy history can become a blueprint for the next era of electricity demand: artificial intelligence. This week, Energy Secretary Chris Wright visited the former Three Mile Island nuclear station—now branded as the Crane Clean Energy Center—to promote a planned restart of the site’s Unit 1 reactor, arguing that more nuclear generation will strengthen reliability, reduce blackout risks, and ultimately push electricity prices down.

NEW YORK — 5:45 a.m. ET, Thursday, Dec. 18, 2025 — Big Tech stocks are trying to steady in early premarket trading after a sharp AI-led pullback rattled the “Magnificent Seven” trade into year-end. The immediate backdrop is macro: investors are bracing for fresh U.S. inflation data and a busy central-bank day in Europe, while the longer-running debate is micro: whether the AI boom’s next phase rewards today’s heavy spending—or punishes it.

Big Tech Stocks Today: Magnificent Seven Slide After AI Funding Jitters Hit the Nasdaq (Dec. 17, 2025)

As of 6:00 p.m. ET on Wednesday, December 17, 2025, Big Tech stocks finished the U.S. session broadly lower, with the AI trade back in the crosshairs. The headline driver wasn’t a single earnings miss from a mega-cap—rather, it was a growing market debate over how the next wave of AI infrastructure gets financed, and whether the returns will justify the scale of spending now embedded in forecasts.

Big Tech Stocks Today (Dec. 17, 2025): Magnificent Seven Slide on AI Infrastructure Jitters as Amazon–OpenAI Talks and Fed Rate Outlook Take Center Stage

Big Tech stocks are setting the tone for U.S. markets on Wednesday, December 17, 2025, with the “Magnificent Seven” trade showing fresh signs of stress even as the sector’s long-term AI narrative keeps expanding. The day’s action is being driven by two competing forces: (1) renewed investor anxiety about the cost and financing of AI infrastructure after a key data-center funding setback tied to Oracle and OpenAI, and (2) a steady stream of “next-wave AI” headlines—from a reported Amazon–OpenAI mega-investment discussion to Alphabet’s push to make its AI chips a real alternative to Nvidia’s ecosystem.

AI stocks are back in the center of the U.S. stock market conversation on Wednesday, December 17, 2025—but with a very different tone than the “everything goes up” phase earlier in the year. Today’s trade is being shaped by three big forces: capital intensity (who can afford to build the compute), platform power (who controls the cloud + chips stack), and software lock-in (who owns the developer workflow). Investopedia+2Reuters+2 That mix is showing up in real time across the AI complex—from Amazon (AMZN) and Microsoft (MSFT) at the model layer, to Oracle (ORCL) in AI cloud buildout, and Nvidia (NVDA) and Alphabet (GOOGL/GOOG) in the fight over the infrastructure and tooling that powers AI development.
