AMD’s shares closed at $515.21 on 10 November, 27.4% above their $404.40 close on 5 November, according to Nasdaq’s daily price history. On the 1,640,087,251 shares on the cover of AMD’s latest Form 10-Q, that is about $181.7 billion of market value added in three sessions, by our arithmetic. Over the same three sessions Nvidia lost about $306.3 billion, its shares down 7.0% from $181.60 to $168.89.
The rebound kept going before the opening bell. AMD traded at $548.52 in pre-market dealing at 6:12 a.m. New York time on 11 November, on Nasdaq’s quote data, 35.6% above the 5 November close. At that price AMD was worth about $899.6 billion, roughly $236.4 billion more than at the 5 November close, by our arithmetic. These are pre-market prices, not closes.

The key insight: As we read it, the 5 November rout did not stick to AMD: by our arithmetic the stock added about $181.7 billion in three sessions and closed 5.4% above its pre-rout close, while Nvidia lost about $306.3 billion over the same closes.
Close (11 Nov). AMD shares closed at $552.90 on Wednesday, up $37.69 or 7.3% from the $515.21 close of 10 November, on Nasdaq’s closing quote at 4 p.m. New York time, 0.8% above the $548.52 pre-market price reported here. On the 1,640,087,251 shares on its latest 10-Q cover, the session added about $61.8 billion of market value, for about $906.8 billion at the close, by our arithmetic. Against the $404.40 close of 5 November the shares are up 36.7%, about $243.6 billion of market value added, by our arithmetic. Nvidia closed 2.9% higher at $173.73. Our close wrap has the rest of the AI trade. Sources: Nasdaq closing quote; Yahoo Finance delayed data as a cross-check.
The starting point is a rout. AMD closed at $488.78 on 4 November and at $404.40 on 5 November, a fall of 17.3% that took about $138.4 billion off its market value in one session, by our arithmetic. That Thursday, 12 large AI stocks closed a combined $1,447.4 billion lower, as we reported.
Then three up days. AMD closed 11.0% higher at $449.04 on 6 November, 13.3% higher at $508.58 on 9 November and 1.3% higher at $515.21 on 10 November, by our arithmetic from Nasdaq’s closes. The 10 November close is 5.4% above the 4 November close, so the stock has more than recovered the rout on closing prices.
Each market value is the closing price multiplied by the 1,640,087,251 shares of common stock that AMD’s 10-Q, filed on 4 November, gives as outstanding on 28 October. On that basis AMD was worth about $663.3 billion at the 5 November close and about $845.0 billion at the 10 November close.
AMD and Nvidia official daily closes from 2 to 10 November 2026, indexed to the 5 November close = 100, from Nasdaq’s price history. AMD closed 27.4% above its 5 November close and Nvidia 7.0% below. The market value changes, about +$181.7 billion for AMD and -$306.3 billion for Nvidia, are our arithmetic on the share counts on each company’s latest 10-Q cover.AMD’s official daily closes from 26 October to 10 November 2026, from Nasdaq’s price history, with the dates of AMD’s own releases: third-quarter results and the fourth-quarter outlook (3 November), the Google Cloud TPU 8tx host role (9 November) and 6th Gen EPYC availability (10 November). The dates show what was published, not what moved the stock.
What AMD Put Out in the Window
AMD itself published three releases around the move. On 3 November, two days before the rout, it reported third-quarter revenue of a record $13.4 billion, up 45% year on year, with Data Center segment revenue of a record $8.5 billion, up 97%. It guided fourth-quarter revenue to approximately $17 billion, plus or minus 3%, which it said is growth of about 66% year on year at the mid-point.
On 9 November AMD said 5th Gen EPYC processors power the host infrastructure for Google Cloud TPU 8tx, which it called the first cloud TPU system to deliver hardware-enforced confidential computing. The same release says EPYC processors are “the host CPU of choice for more than 10 leading hyperscalers and frontier AI labs”, across GPUs and custom accelerator chips.
On 10 November AMD announced general availability of 6th Gen EPYC server processors, based on its Zen 6 architecture, with systems shipping from server makers and cloud instances from Microsoft Azure and OCI “generally available soon”. Outside AMD, Oppenheimer upgraded the stock to Outperform with a $600 target, per a note relayed on 9 November. On 11 November a slide in Anthropic’s IPO roadshow video put the bring-up of one Anthropic model on AMD MI355X GPUs at about three days, as we reported.
Against Nvidia
Nvidia moved the other way after its first rebound day. It closed at $181.60 on 5 November, rose to $186.64 on 6 November, then fell to $178.67 on 9 November and $168.89 on 10 November, on Nasdaq’s closes. On the 24.1 billion shares on the cover of Nvidia’s latest 10-Q, as of 21 August, the fall from the 5 November close is about $306.3 billion, by our arithmetic.
Put side by side, AMD’s $181.7 billion gain is about 59% of Nvidia’s $306.3 billion loss over the same three sessions, by our arithmetic. Nvidia traded at $176.71 in pre-market dealing at 6:12 a.m. New York time on 11 November, still 2.7% below its 5 November close. We tracked Nvidia’s fall from its October peak separately.
The Structural Read
As we read the closes, the market separated two AI chip makers that fell together on 5 November: AMD recovered more than its one-day loss of about $138.4 billion, while Nvidia ended 10 November 7.0% below its 5 November close.
As we read AMD’s own releases in the window, the company kept pointing at the CPU side of AI as well as its GPUs: a host role for Google Cloud TPU 8tx, which AMD said makes EPYC the host CPU of choice at more than 10 hyperscalers and frontier labs, and 6th Gen EPYC availability.
Lisa Su, AMD chair and CEO, 3 November 2026
“Demand for our Instinct and EPYC products continued to strengthen, and we expect growth to accelerate further in the fourth quarter as we scale Helios and ‘Venice’ production.”
Three Implications
FOR AMD HOLDERS On official closes the stock is back above its 4 November level; the 11 November pre-market price of $548.52 is not a close and can change before the 9:30 a.m. New York open.
FOR THE AI CHIP TRADE Over the same three sessions AMD added about $181.7 billion and Nvidia lost about $306.3 billion, by our arithmetic; AMD’s gain is about 59% of Nvidia’s loss.
FOR THE NEXT DATA POINT AMD guided fourth-quarter revenue to approximately $17 billion, plus or minus 3%, growth of about 66% year on year at the mid-point, by its own figures.
The framework says: “Inference is a revenue engine: continuous, distributed across millions of applications and agents, incurring marginal cost with every query.”
As we read it, AMD’s releases in the window speak to that engine on two fronts: GPUs for model work and EPYC CPUs as hosts and agent servers. The framework predates the share moves and does not discuss them.
What Is Not Established
None of the documents we read gives a reason for the share moves, and AMD’s releases do not comment on its share price. We do not attribute the rebound to any single release, note or slide; the dates above show what was published, not what moved the stock. The pre-market prices can change before the regular session opens at 9:30 a.m. New York time (14:30 UTC), and the 11 November figures are not closes. The share counts are from the latest 10-Q covers and do not count later issuance.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
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.
AMD closed 10 November at $515.21, 27.4% above its 5 November close and 5.4% above its close before the rout, adding about $181.7 billion of market value in three sessions by our arithmetic. Nvidia lost about $306.3 billion over the same sessions. Before the 11 November open AMD traded 35.6% above its 5 November close. AMD’s own releases in the window cover a record third quarter, a $17 billion fourth-quarter outlook, the Google Cloud TPU 8tx host role and 6th Gen EPYC availability.
A note on sourcing. Closing prices are Nasdaq’s official daily closes for AMD and Nvidia; the 11 November prices are Nasdaq pre-market quotes timed at 6:12 a.m. New York time and are not closes. Share counts are from the covers of each company’s latest Form 10-Q on SEC EDGAR. We read AMD’s releases of 3, 9 and 10 November in full. Every market value, percentage change and comparison is our arithmetic. We did not contact AMD or Nvidia.
