CoreWeave, Inc. stock is ending Monday, December 15, 2025, under heavy pressure—and the story is bigger than a single red day. After the closing bell, shares held near the day’s settlement level following a sharp selloff driven by fresh “insider selling” headlines, while investors continue to weigh CoreWeave’s breakneck AI-infrastructure buildout against capital intensity, leverage, and dilution risk.
Below is what matters after the bell today (12/15/2025)—and what to keep on your radar before the U.S. stock market opens tomorrow, Tuesday, December 16, 2025.
CoreWeave stock price after the bell: where CRWV closed and where it traded in extended hours
CoreWeave (CRWV) finished the regular session at about $72.35, down roughly 7.9% on the day, according to end-of-day pricing and historical data. [1]
- Close (Dec. 15): $72.35 (‑7.94%) [2]
- Day’s range: about $72.03 to $79.58 [3]
- Volume: about 30.19 million shares [4]
In after-hours trading, CRWV was still around $72.35 as of 5:45 p.m. ET (22:45:58 UTC), with total day volume reported around 31.0 million shares.
One key takeaway from that “flat after hours”: today’s move looks like a regular-session repricing, not a late-day reversal caused by a new after-close surprise release.
Why CoreWeave stock fell today: “insider selling” headlines hit at a sensitive moment
The cleanest explanation for today’s drawdown is selling pressure meeting a nervous tape—and today’s news flow gave traders a clear headline.
A MarketBeat report published today framed the slide around heavy insider selling and elevated volume. [5] But to understand whether the transactions are truly “bearish,” it’s important to read what the actual SEC filings say—because multiple sales were tied to 10b5‑1 plans or tax withholding rather than discretionary “I’m bailing out” selling.
1) CFO Nitin Agrawal: sale tied to tax withholding on RSU vesting
CoreWeave CFO Nitin Agrawal reported a sale of 66,467 shares at a weighted average price of $82.5753 (with trades ranging from $82.48 to $82.58). [6]
Crucially, the filing explains the sale was to satisfy tax withholding obligations connected to RSU vesting and settlement. [7]
That doesn’t automatically make it bullish—but it does change the interpretation versus an unprompted open-market sale.
2) Co-founder/CSO Brian Venturo: sales under a 10b5‑1 plan
A Form 4 for Brian M. Venturo shows multiple sales on December 10, 2025, and the filing explicitly notes the transactions were executed pursuant to a Rule 10b5‑1 trading plan adopted May 21, 2025. [8]
10b5‑1 plans are commonly used to schedule sales in advance to reduce insider-trading concerns; again, that’s not automatically positive, but it reduces the signal value versus a surprise, discretionary dump.
3) Chief Development Officer Brannin McBee: sale under a 10b5‑1 plan
A Form 4 for Brannin McBee shows a sale executed pursuant to a Rule 10b5‑1 plan adopted September 2, 2025. [9]
The filing also shows sales at about $83.8034 on December 8, 2025. [10]
Why the market still cared today
Even when sales are “mechanical,” the market often reacts because:
- Timing: CRWV is already volatile and has been sliding in recent sessions. From Dec. 9 ($90.66) to Dec. 15 ($72.35), the stock is down about 20%. [11]
- Narrative: CoreWeave is frequently described as an AI infrastructure “high beta” name—insider-sale headlines can reinforce risk-off positioning, regardless of the nuance.
- Liquidity/flow: Today’s trading volume was heavy, and momentum-driven participants can amplify downside moves.
Today’s other major headline: NJEDA and CoreWeave announce a $20M AI Hub Fund
Not all the news around CoreWeave today was negative. On December 15, 2025, the New Jersey Economic Development Authority (NJEDA) and CoreWeave (with other accredited investors) announced the creation of a $20 million investment fund linked to the NJ AI Hub Strategic Innovation Center, aimed at supporting startups. [12]
Key details from the NJEDA release:
- The NJEDA Board approved a $10 million investment, matched by an equal investment from CoreWeave and affiliated investors. [13]
- The release also says Plug and Play will manage an accelerator program at the Strategic Innovation Center, and notes a $3.8 million grant awarded to Plug and Play tied to an “AI Challenge.” [14]
- CoreWeave co-founder/CSO Brian Venturo is quoted emphasizing jobs and economic impact, calling the commitment designed to deliver “real benefits” for New Jersey residents. [15]
For CRWV investors, this is more of a strategic ecosystem signal than a near-term earnings lever. It reinforces CoreWeave’s role as a visible anchor in the “AI economy” buildout—especially in New Jersey—but it likely doesn’t change the next quarter’s revenue or capex math on its own.
The bigger backdrop: CoreWeave’s growth story is colliding with capital intensity and leverage worries
Even before today’s selloff, CoreWeave has been living inside a debate that tends to define AI infrastructure plays:
Is the company building an enduring “AI utility”… or overextending financially to chase demand?
Convertible notes are still fresh in investors’ minds
CoreWeave’s investor relations site reported last week that it priced an upsized $2.25 billion offering of 1.75% convertible senior notes due 2031, with an initial conversion price of about $107.80 per share (a premium to the then-recent stock price). [16]
The company also disclosed expected net proceeds (roughly $2.21B net, before expenses, with additional upside if the overallotment is exercised) and described the use of proceeds, including funding capped call transactions intended to reduce dilution. [17]
Why this matters going into tomorrow:
- Convertibles can be interpreted as smart, lower-coupon financing—or as a sign the company needs constant capital to fund expansion.
- The issuer also notes hedging activity around capped calls and derivatives could affect the stock price. [18]
Data-center execution risk is still part of the narrative
In its third-quarter update reported by Reuters (from November), CoreWeave beat revenue estimates but also flagged impacts from a delay in bringing online a data center, and trimmed its 2025 revenue forecast to $5.05B–$5.15B from $5.15B–$5.35B.
That matters because CoreWeave’s valuation hinges on confidence that it can:
- secure GPUs and capacity,
- deploy at speed, and
- convert demand into realized revenue without bottlenecks.
Today’s sentiment headwind: AI data center stocks moved lower broadly
CoreWeave didn’t trade in a vacuum Monday. Investor’s Business Daily highlighted that AI data center stocks fell in a session where Oracle shares slid after earnings, and the piece specifically lists CoreWeave among names trading down on the day. [19]
For CRWV holders, this is important because it suggests:
- Today wasn’t only “CoreWeave-specific”; there was also a sector mood component.
- If the broader AI infrastructure basket bounces tomorrow, CRWV could see sympathetic movement—and vice versa.
CoreWeave stock forecast and analyst outlook: what the Street is pricing in
Analyst targets for CRWV remain wide—typical for a newly public, fast-scaling company.
MarketBeat’s aggregated view lists:
- Consensus rating: Hold
- Average price target:$129.47
- Range (high/low targets shown):$200 high and $32 low [20]
That spread is the point: the market is still trying to decide whether CoreWeave becomes a durable AI infrastructure leader—or whether financing needs and execution risks cap upside.
Meanwhile, a Motley Fool analysis published this morning underscores the same tension: it highlights CoreWeave’s AI-focused cloud model (buying Nvidia GPUs and renting compute to major AI customers), while emphasizing the company’s heavy capital spending versus revenue and the challenge of hardware refresh cycles. [21]
What to know before the market opens tomorrow (Tuesday, Dec. 16, 2025)
Here’s a practical checklist to carry into the premarket.
1) Watch whether “insider selling” stays the headline—or gets reframed
If traders and commentary continue focusing on “insider selling,” CRWV could remain under pressure even without new filings.
But if the conversation shifts toward the 10b5‑1 and tax-withholding details in the Form 4s, some of the emotional sting can fade—especially if the broader market is green. [22]
2) Pay attention to the $72 area immediately
Today’s intraday low was ~ $72.03, and the stock settled near $72.35. [23]
That effectively makes ~$72 the first “line in the sand” investors will watch at the open, simply because it’s where buyers finally stepped in today.
3) Macro catalyst: U.S. Retail Sales is scheduled for 8:30 a.m. ET
The U.S. Census Bureau’s schedule indicates the October 2025 Advance Monthly Retail Trade report is set for release on December 16, 2025 at 8:30 a.m. [24]
High-growth tech and AI infrastructure names can react sharply to macro data that moves:
- interest rate expectations,
- Treasury yields, and
- overall risk appetite.
4) Keep an eye on “AI infrastructure” peers and Nvidia-related sentiment
Even if there’s no new CoreWeave press release overnight, CRWV often trades on the broader AI ecosystem’s mood.
One example: a MarketWatch piece discussing Nvidia’s bear case referenced an arrangement with CoreWeave in which Nvidia is described as required to buy unused compute capacity. [25]
Whether investors view that type of structure as a stabilizer or a risk factor can influence sentiment around AI supply chains.
5) Remember the short-term context: CRWV has been volatile for weeks
Motley Fool notes CRWV has been a “roller-coaster” in 2025—up sharply since its IPO period yet well off its highs—so outsized daily swings are part of the risk profile. [26]
That’s relevant heading into tomorrow because it raises the odds of:
- fast gap moves at the open,
- exaggerated reactions to premarket headlines, and
- momentum-driven swings around key price levels.
Bottom line for CoreWeave stock tonight
CoreWeave ends Dec. 15 with a decisive down move and heavy volume, and the immediate catalyst is the market’s reaction to insider-sale headlines—though the SEC filings add nuance around 10b5‑1 plans and tax-related selling. [27]
At the same time, CoreWeave continues to push strategic ecosystem initiatives (like the $20M NJ AI Hub Fund announced today), while investors remain focused on the company’s capital intensity, financing strategy, and execution risks as it scales AI compute capacity. [28]
