AI Stocks Add $253B; CoreWeave Has Best Day Since June 2025

CoreWeave closed 24.7% higher at $60.77 on Wednesday, its biggest one-day gain since June 2025, as the AI trade rallied a day after its third-quarter results. Micron rose 11.9%, Oracle 8.8% and Nvidia 2.9%, in delayed exchange data from Yahoo Finance read after the 4 p.m. New York close. Wall St Engine flagged the moves in a post on X at 20:11 UTC, before the close.

Together the four added about $253 billion of market value in the session, by our arithmetic on share counts from their latest SEC filings. Nvidia, the smallest mover in percentage terms, supplied about $116.6 billion of it, 46%. Adding SK hynix’s 5.4% gain in Seoul takes the total to about $289 billion. Anthropic’s pre-IPO perpetual contract on the Liquid exchange, which trades around the clock, stood at an implied $1.83 trillion after the US close, about 1.8 times the top of Anthropic’s filed IPO range, by our arithmetic.

Business Pill · Financial Conditions

A short explainer on financial conditions. It teaches the general idea only and does not discuss Wednesday’s trading or Anthropic.

The key insight: As we read it, the close shows where the market booked CoreWeave’s results: CoreWeave rose the most in percentage terms but added about $6.6 billion, while Nvidia’s 2.9% move added about $116.6 billion and Micron’s about $97.5 billion, by our arithmetic.

What Was Posted

Wall St Engine’s post reads: “Strong day across the AI trade as CoreWeave’s earnings lifted sentiment”. It lists “$CRWV +24% – Best since June ’25”, “$MU +15% – Best since July”, “SK hynix +11%”, “$ORCL +10%” and “$NVDA +4%”, and adds that “Anthropic’s pre-IPO perp on @liquidtrading also rose 8% to an implied $1.82T valuation amid strong IPO demand”.

The post went out at 20:11 UTC, 49 minutes before the close, so its percentages are intraday. Our earlier midday read of the same rally took one snapshot at 18:01 UTC; this piece uses closing prices.

What Was Posted on X

Wall St Engine posted this at 20:11 UTC on 11 November, before the US close: it lists intraday gains for CoreWeave, Micron, SK hynix, Oracle and Nvidia and says Anthropic’s pre-IPO perp on Liquid rose 8% to an implied $1.82T. This piece checks those figures against closing prices and Liquid’s own market page.

The Closing Numbers

CoreWeave closed at $60.77 against $48.73 on Tuesday. On the 551.5 million Class A and Class B shares on its latest 10-Q cover, that adds about $6.6 billion, by our arithmetic. The move follows its third-quarter results, filed in an 8-K at 21:05 UTC on Tuesday.

Micron closed at $811.30, up from $725.11: about $97.5 billion on its 1,131,423,212 shares, by our arithmetic. Nvidia closed at $173.73 from $168.89, about $116.6 billion on the 24.1 billion shares on its 10-Q cover. Oracle closed at $128.40 from $117.98, about $32.4 billion on its 10-Q cover count plus the 86,206,897 shares it sold in an offering that closed on 4 November, per its 8-K.

SK hynix closed at ₩1,277,000 in Seoul, up 5.4% from ₩1,212,000, hours before New York opened. On the 728,865,500 shares in its July ADS prospectus that is about ₩47.4 trillion, or about $35.4 billion at 1,338.92 won to the dollar, by our arithmetic. Its ADS on Nasdaq, each one-tenth of a share, closed 9.7% higher at $142.25.

The PHLX Semiconductor index rose 5.7%, the Nasdaq Composite 1.6% and the S&P 500 1.3%, per the same data.

Checking the Best-Since Claims

We checked both claims against daily closing prices. CoreWeave’s 24.7% is its largest one-day gain since 3 June 2025, when it rose 25.2%; the post’s “since June ’25” holds at the close. Micron’s 11.9% is its largest since 30 July, when it rose 18.4%, so “since July” also holds, by our count.

The post’s 15% for Micron and 11% for SK hynix are larger than the closing moves. SK hynix’s Seoul shares closed 5.4%; the post’s figure is nearer its Nasdaq ADS, which closed 9.7%.

The Anthropic Perp

Liquid’s ANTH market page, read at 21:06 UTC, showed a price of $1,829.10, “up 7.15% over the last 24 hours”, in a 24-hour range of $1,713.90 to $1,874.50. The page says “each point of price stands for $1.00B of Anthropic’s valuation”.

Liquid describes the market as “a contract price linked to an oracle reference price, not an actual unlisted-share transaction price or a confirmed IPO price”. Its explainer says: “Traders are taking price exposure — not becoming Anthropic shareholders.” It is a derivatives price, not a valuation from Anthropic.

Anthropic’s amended S-1 of 10 November sets a range of $70 to $78 a share. On the 13,086,672,593 shares it says will be outstanding after the IPO and a private placement, we put the range at $917 billion to $1.02 trillion. The perp’s $1.83 trillion is about 1.8 times the top and 1.9 times the $968.4 billion midpoint; spread over that share count it would be about $140 a share, by our arithmetic.

The Structural Read

As we read the day, the gains ran through the companies CoreWeave buys from, memory (Micron, SK hynix) and GPUs (Nvidia), and through another AI cloud, Oracle, all in the session after one GPU cloud reported.

As we read the Liquid price, it is a cash-settled bet on an oracle reference price for Anthropic; at about 1.8 times the top of the filed range, it prices a far higher valuation than the range itself, by our arithmetic.

Three Implications

FOR THE AI TRADE CoreWeave, Micron, Oracle and Nvidia added about $253 billion at the close on share counts from their filings, by our arithmetic.

FOR THE CLAIMS CoreWeave’s best day since June 2025 and Micron’s since July both hold on closing prices; the post’s 15% and 11% were intraday or ADS figures.

FOR ANTHROPIC’S IPO The filed range is $70 to $78 a share; the Liquid perp, a cash-settled derivative, implied $1.83 trillion after the US close.

The Business Engineer Lens

This story maps onto the Business Engineer framework The AI Capex Map & The State of AI Hyperscalers.

The framework reads: “The $1T capex cycle is being underwritten by a $1T concentrated demand commitment from two counterparties whose combined free cash flow is deeply negative.”

As we read it, Wednesday priced both ends of that sentence on one day: the suppliers of the build-out rose after CoreWeave’s results, and a derivatives market put one of the two counterparties, Anthropic, at 1.8 times its own filed range. The framework predates the session and does not discuss it.

Anthropic implied valuation: Liquid perp vs the S-1/A IPO range
Anthropic implied valuation, US$ billions: the low, midpoint and top of the $70 to $78 range in its 10 November S-1/A on the 13,086,672,593 shares it says will be outstanding (our arithmetic), the $965 billion May Series H post-money valuation (as stated by Liquid), and Liquid’s ANTH perp read after the US close on 11 November (1 point = $1 billion, per Liquid). The perp is a cash-settled derivative, not a company valuation.

What Is Not Established

The link from CoreWeave’s results to the other moves is Wall St Engine’s reading, not a statement from the companies. Yahoo’s prices are delayed exchange data, and the share counts are as of each filing date (CoreWeave’s cover is dated 31 July, Nvidia’s 21 August), so the market values are estimates. Liquid’s pages we read do not say which share count its valuation assumes. Anthropic has not priced its IPO. We did not contact the companies, Liquid or Wall St Engine.

This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.

A note on sourcing. We read Wall St Engine’s post on X, closing prices from Yahoo Finance’s delayed exchange data read after the 21:00 UTC close (SK hynix: the Korea Exchange close), daily closing prices back to each stock’s listing or five years for the best-since checks, Liquid’s ANTH market page and its explainer, Anthropic’s amended S-1 of 10 November, and the share counts in CoreWeave’s and Nvidia’s 10-Q covers, Micron’s 10-K, Oracle’s 10-Q and 4 November 8-K and SK hynix’s July ADS prospectus.

Market values added, the won conversion, the multiples of the IPO range and the per-share figure are our arithmetic. We did not contact the companies, Liquid or Wall St Engine.
