AI summary
CoreWeave filed for $3.0 billion in convertible notes and an at-the-market program for 35 million shares, which is 7.6% of existing shares. The note’s view is that premarket trading treated new contract pricing of about $40 million per megawatt as the main story, while treating the large capital raise as secondary plumbing, resulting in an initially unchanged stock price.
For historical context, the note states there is no analog range for this ticker on this clock, so no prior five-session distribution is provided. The strongest other reading is that a company with a $104.2 billion backlog can raise this capital as working capital. The immediate checkpoint is the closing price of the first session after the filing, which was September 17.
Two paragraphs generated from the note. The authored note below is the record. Numbers only, no side.
1. The state
As of the 2026-09-16 close. Session 1 has closed.
September 16 identity is built. This clock has no analog band.
2. What's new
8-K / prospectus, morning of 2026-09-17
$3.0B converts due 2033 and an ATM for 35 million Class A shares. Coupon not priced.
3. What that does to the state
Changes claims on the firm: new debt-like paper and more shares. That can be a new place even if yesterday's chart identity has not been rebuilt.

The band is the prior close's neighborhood — what followed similar states as of the cutoff.
4. Same state, or a new one
Left yesterday's range
Session 1 vs the market: -5.3. Prior-state 1-session range: -4.9 / +0.0 / +5.0.
CRWV closed at $79.88, -4.2% versus the $83.35 close of 2026-09-16, on 78.9 million shares, about 3.8 times the 20-day average; the session's range was $78.27 to $82.43 after a $81.45 open. Against the market (SPY +1.1%), the excess move was -5.3 points.
New-state is wrong if the convert is already how this name finances and Thursday's identity does not move.
Session 1: -5.3 vs band -4.9/+0.0/+5.0, left yesterday's range. Session 5: +2.4 vs band -13.0/-1.1/+12.6, stayed in range. Session 10: +3.4 vs band -19.4/-2.1/+13.5, stayed in range. Scorecard
When we look again
Session 1: September 17 close. Session 5: September 23. Session 10: September 30. Company: convert pricing, expected after the close; next 10-Q in November.
CoreWeave filed this morning for $3.0 billion of convertible notes due April 2033, with a $500 million option for the banks, and separately an at-the-market program for up to 35 million Class A shares. Coupon and conversion price come at pricing, after the close. There were 458.9 million Class A shares outstanding on July 31. 35 million is 7.6% of that. At Wednesday's $83.35 close the ATM is $2.9 billion of paper if it all prints there. Sales-agent commission is up to 2%.
In the same prospectus they said they have been signing short-dated contracts at about $40 million per megawatt, three to six months, added more than $25 billion of net new commitments between June 30 and August 11, and took contracted power from 3.7 to 4.2 gigawatts. Second-quarter revenue was $2.58 billion. Backlog was $104.2 billion. Debt around that quarter was about $36 billion.
The filing is a raise sitting next to a demand number. Premarket the stock is about $83, roughly unchanged. That is the tape treating $40 million per megawatt as the story and $3 billion plus the ATM as plumbing. Thursday's session prices both.
Other reading, tape, and sources
The other reading
A company with $104 billion of backlog and $25 billion of new commitments can raise $3 billion of converts and keep an ATM as working capital. If Thursday holds $83, the tape is right that $40 million per megawatt is the news and the paper is plumbing. Existing 1.75% converts due 2031 and 2032 already showed the bid for CoreWeave equity optionality.
What would change this
We are wrong if convert pricing is a high premium and a low coupon and the stock holds through five sessions, or if a later 8-K shows the ATM unused.
The wash reading is wrong if Thursday or the five-session window reprices the stock by most of the ATM's $2.9 billion of paper.
Inconclusive if neocloud names move together and the CoreWeave terms cannot be isolated.
The tape
CoreWeave closed the September 16 regular session at $83.35, up 3.0% from Tuesday's $80.92, on 18.4 million shares, a little under the 20-day average. Premarket at 07:58 ET the last print was $83.00, 0.4% below that close. It ranked third on Stocktwits and second on Yahoo in a 07:15 ET capture.
What was filed
The 8-K was accepted at 07:13 ET with Exhibit 99.1. The 424B5 ATM was accepted at 07:11 ET. Coupon, conversion rate and capped-call cap are not set. The $40 million per megawatt figure and the $25 billion of new commitments are in the prospectus, not a separate operating 8-K. The issuer news and presentations pages were not reachable at check time; this note uses the 8-K and the 424B5.
The numbers around the move
Second-quarter revenue was $2.575 billion, up 112%. Backlog $104.2 billion as of June 30, before the $25 billion of early-Q3 commitments. Our labelled reading: the tape is netting that demand print against $3.0 billion of converts and a 7.6% ATM, and this morning it is calling that a wash. Coupon and premium are still blank.
What the stock did
Not yet observed as a completed session after the filings. The September 16 regular close was $83.35, before the 8-K. Premarket at 07:58 ET the last print was $83.00. Session 1 is the September 17 regular session.
Close update, session 1 (September 17, written after the close): CRWV closed at $79.88, -4.2% versus the $83.35 close of 2026-09-16, on 78.9 million shares, about 3.8 times the 20-day average; the session's range was $78.27 to $82.43 after a $81.45 open. Against the market (SPY +1.1%), the excess move was -5.3 points. There is no Chart Library analog range for CRWV on that clock, so we cannot say whether the session stayed in or left a prior neighborhood.
The comparison
Chart Library has a September 16 identity for CoreWeave but no analog band for this clock: the 1-day embedding the memory uses is not attached. We are not printing a distribution. These are not a forecast, and they suggest no side.
