NVIDIA Stock After Hours Today (NVDA): What Moved Shares on Dec. 16, 2025—and What to Watch Before the Market Opens Dec. 17

NVIDIA Stock After Hours Today (NVDA): What Moved Shares on Dec. 16, 2025—and What to Watch Before the Market Opens Dec. 17

NVIDIA Corporation stock (NASDAQ: NVDA) was modestly higher in late trading Tuesday, with early after-hours action showing shares edging up from the 4:00 p.m. ET close. NVDA finished the regular session around $177.40 and traded near $177.54 shortly after the bell (around 4:08 p.m. ET). [1]

The lack of a dramatic after-hours swing is notable given the heavy headline flow around Nvidia’s expanding software ecosystem, fresh debate over “AI bubble” risk, and a macro backdrop that’s keeping rate expectations in flux. Here’s what matters most heading into Wednesday’s open.


NVDA after the bell: where Nvidia stock stands tonight

After-hours trading can be thin and jumpy, so levels can change quickly—but as of the early after-hours window:

  • Regular-session close: about $177.40 [2]
  • Early after-hours: about $177.54 (a small gain) [3]
  • Tuesday range / activity snapshot: the latest data feed showed NVDA trading between roughly $174.64 and $178.16 during the session.

Why the muted reaction? Because today’s biggest Nvidia-specific developments are more “platform strategy” than “near-term revenue surprise”—important for the long game, but not always an immediate after-hours catalyst unless they change guidance.


The big Nvidia story driving today’s conversation: software, openness, and ecosystem control

1) Nvidia’s SchedMD acquisition (Slurm) is a strategic bet on “AI operations,” not just chips

One of the most consequential items in the current news cycle is Nvidia’s acquisition of SchedMD, the primary commercial steward behind Slurm, a widely used open-source workload manager for high-performance computing (HPC) and AI clusters. Nvidia’s message: Slurm stays open-source, but Nvidia wants tighter integration across its accelerated computing stack. [4]

Why markets care:

  • Slurm sits in the “traffic control tower” of AI clusters—helping allocate GPU time, schedule jobs, and maximize utilization. In a world where a single training run can tie up massive compute fleets, scheduling efficiency becomes a competitive weapon. [5]
  • Nvidia is effectively widening its moat: not only selling GPUs and networking, but also nudging the orchestration layer that governs how those resources get used.

This plays directly into a key investor debate for 2026: whether Nvidia’s advantage stays durable as competitors push alternatives in silicon and software.

2) Nemotron 3: Nvidia leans harder into open models

Nvidia also unveiled the Nemotron 3 family of open models, data, and libraries aimed at “agentic AI” development, using a mixture-of-experts approach and multiple size tiers. [6]

Why this matters to NVDA holders: It reinforces the argument that Nvidia isn’t just a chip supplier—it’s positioning as a full-stack AI platform provider, extending influence from silicon to developer tooling to model ecosystems.


“AI bubble” fears vs. AI capex reality: the debate investors are trading

A major theme in today’s Nvidia coverage: whether the AI infrastructure buildout is overheating—or simply moving from “hype” to “industrial scale.”

  • UBS strategists pushed back on bubble concerns, projecting global AI capital expenditure rising from $423 billion in 2025 to $571 billion in 2026, and estimating a multi-trillion-dollar AI revenue opportunity by 2030. [7]
  • Meanwhile, the market’s mood has been choppy—partly because investors are demanding clearer returns on AI spending, not just bigger budgets.

What this means for NVDA tomorrow: If traders wake up risk-on, Nvidia tends to benefit as a bellwether AI name. If they wake up risk-off, Nvidia can get sold simply because it’s liquid and heavily owned—even when company-specific news is constructive.


Analyst forecasts and street views hitting the tape today

While Wall Street’s NVDA opinions span a wide range, today’s headline analyst framing leaned constructive on the medium-term AI cycle:

  • A Jefferies analyst highlighted Nvidia among top chip picks for 2026 and set a $250 price target for Nvidia in that outlook, pointing to product pipeline momentum (including references to upcoming platforms). [8]

Take those targets for what they are—models built on assumptions—but note how they connect to the current market narrative: Nvidia’s valuation is increasingly being judged on how long the AI infrastructure cycle stays intense.


Macro matters tonight: rates, growth signals, and why they can move NVDA at the open

Nvidia is a mega-cap growth stock, so it’s highly sensitive to two things: bond yields and risk appetite.

Today’s macro headlines were mixed:

  • A Reuters market wrap highlighted shifting expectations for rate cuts as investors digested labor-market data and broader growth signals. [9]
  • Separately, U.S. business activity growth slowed to a six-month low in December in S&P Global’s preliminary PMI reading—another data point feeding the “growth cooling” discussion. [10]
  • A delayed report showed retail sales flat in October, adding to uncertainty about consumer momentum heading into year-end. [11]

Why it matters for Wednesday: If yields fall on cooling-growth data, that can support high-duration tech like NVDA. If inflation worries push yields up, it can pressure the whole AI trade even without Nvidia-specific negatives.


What to watch before the market opens tomorrow (Wednesday, Dec. 17)

Here’s the practical pre-open checklist for NVDA traders and investors:

1) Premarket liquidity and headline sensitivity

Extended-hours price action can be noisy—especially if big macro headlines hit before 9:30 a.m. ET. Also note that market structure itself is in focus: Nasdaq’s push toward much longer trading hours has been a major story, with plans targeting a 23-hour weekday model in 2026 (pending approvals and infrastructure readiness). [12]
That matters because it underscores how “after-hours reaction” is becoming a more important signal—and potentially more volatile.

2) Scheduled events: earnings and market-moving releases

Even when Nvidia isn’t reporting, the broader tape can set the tone. For Wednesday morning, Nasdaq flagged a slate of pre-market earnings (including General Mills and Jabil, among others). [13]
Macro calendars also show key releases clustered midweek, which can change the rate/risk backdrop quickly. [14]

3) Nvidia’s next major “known catalyst”: earnings date and the guidance baseline

Nvidia’s Investor Relations calendar lists Feb. 25, 2026 for its 4th Quarter FY26 financial results. [15]
And the current guidance baseline investors keep returning to is Nvidia’s Q4 FY26 revenue outlook of $65.0B ±2%, issued with its Q3 FY26 results. [16]
Between now and then, the stock will trade on: demand signals (especially data center), supply/shipments, and policy headlines.

4) Technical levels traders are watching

Several market outlets noted Nvidia remains below its 50-day moving average, a level that often acts like a psychological line in the sand for momentum funds. [17]
As of Tuesday, one widely cited 50-day measure sat around the mid-$180s, leaving NVDA with technical “work to do” if it wants to regain a cleaner uptrend. [18]


The China/exports angle: still the headline risk that can appear overnight

Even when today’s tape is calm, NVDA can gap on policy news. The U.S.-China AI chip relationship remains a live variable, and markets have been highly reactive to changes in export posture (including recent reporting around permitted shipments and associated policy frameworks). [19]
Meanwhile, China’s domestic AI chip push continues—highlighted today by reporting that Chinese AI chip firm Biren is preparing a Hong Kong IPO, underscoring the competitive race under export controls. [20]


Bottom line for Wednesday’s open

Nvidia’s after-hours move tonight looks incremental—not a shock reaction. But don’t confuse “quiet after-hours” with “nothing to watch.” Heading into Dec. 17, NVDA is sitting at the intersection of:

  • Company-specific ecosystem expansion (SchedMD/Slurm + Nemotron 3) [21]
  • A market-wide AI spending debate (bubble fears vs. capex reality) [22]
  • Macro rate sensitivity driven by growth/inflation data flow [23]
  • Technicals that many traders will treat as a near-term road map [24]

  • Pfizer's tepid 2026 outlook dents shares after Metsera deal
    December 16, 2025, 4:45 PM EST. Pfizer's acquisition of Metsera deepens its weight-loss drug portfolio, but a tepid 2026 outlook weighed on the stock. The company guides revenue of $59.5-62.5B in 2026, roughly flat vs 2025's $62B, and expects a dip in earnings per share (EPS) as it digests the deal and ramps up R&D. Pfizer kept its dividend but has not pursued share repurchases in 2025, saying capital should fund new programs. Analysts at Briefing.com call the results a painful transition out of the Covid era. The company also flags vaccines as a continued investment, even as policy shifts loom. Pfizer shares fell about 3.8% in trading.
