The $26 billion that Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC agreed to put into Anthropic alongside its IPO was a private placement of Anthropic’s Class N common stock at the IPO price, Reuters reported, citing the original filing copy Anthropic sent to banks. Under Anthropic’s public S-1/A of 2 November, “shares of Class N common stock have no voting rights, except as otherwise required by law”.
Three of the seven buyers, Broadcom, Google and Microsoft, are counterparties to $327.4 billion of the $643.8 billion in compute contracts with stated amounts in that S-1/A, or 50.9%, by our arithmetic. The $26 billion would be 7.9% of what Anthropic has agreed to pay those three.
Business Pill · Financial Conditions
An evergreen Business Engineer explainer on financial conditions. It teaches the general idea only and does not discuss Anthropic.
The key insight: Reuters reported that the $26 billion seven technology companies agreed to invest alongside Anthropic’s IPO is a private placement of Class N common stock at the IPO price; Anthropic’s public S-1/A says Class N shares have no voting rights except as required by law. Three of the buyers, Broadcom, Google and Microsoft, are counterparties to $327.4 billion of the $643.8 billion in compute contracts with stated amounts in the S-1/A, by our arithmetic.
Reuters’ updated story says the original filing showed the seven companies “had agreed to participate in the private placement of Anthropic’s Class N common stock at the IPO price, which would close immediately after the IPO”. It was in the same filing copy whose pricing details Anthropic later told bankers were inaccurate, as we reported in Anthropic Retracts $70 to $80 IPO Range It Sent to Bankers.
Reuters says the email “did not specify to bankers what was erroneous” and that it “was unable to determine what was incorrect”. Anthropic declined to comment. Reuters gives the $26 billion as a combined figure for the seven and does not give each company’s share.
Anthropic’s seven compute contracts with stated amounts in its S-1/A of 2 November, in billions of dollars. Highlighted: Broadcom, Google and Microsoft, three of the seven companies Reuters names as buyers in the $26 billion Class N placement. Their $327.4 billion, 50.9% of $643.8 billion, is our arithmetic. SpaceXAI and Nscale are up-to amounts.
What Class N Stock Is, Per the S-1/A
The S-1/A’s capital-structure table gives Class A stock one vote per share and Class N none. Class N holders are “Not entitled to vote except as required by law”. The filing says the two classes have identical rights “except with respect to voting and conversion”, and that “The holders of our Class N common stock are primarily strategic business partners”.
The filing says Class N shares “will automatically convert into an equal number of shares of Class A common stock” when sold through a registered offering or on the open market, or transferred to an unaffiliated third party that will not own more than 9.99% of any class. The filing says that while held as Class N, “these shares are non-voting and therefore do not impact the voting power of the holders of our Class A common stock”; once converted, the new Class A shares carry one vote each.
Neither class changes the founders’ share of the vote. The S-1/A says future Class A and Class N issuances “will not dilute the voting power of our Class F common stock”, the single share held by the co-founders’ Founder LLC that carries a fixed 50.1% of the vote. Our full read of the share classes is in Who Owns Anthropic?.
The Seven Buyers in Anthropic’s Own Filing
Broadcom: five-year master equipment leases whose rent “equal to an aggregate of approximately $161.2 billion excluding interest” over their life, giving Anthropic “access to TPU-based compute capacity”. Google: a CSP hosting agreement under which Anthropic “committed to spend at least approximately $121.3 billion between April 2026 and July 2033, regardless of actual usage”. Microsoft: an agreement to spend “an aggregate of at least $44.9 billion between November 2026 and June 2033”.
AMD: a July 2026 hardware supply agreement for Helios rack-scale systems with MI450 GPUs, under which AMD “has provided a commitment to purchase up to $5.0 billion of our Class N common stock”, available in increments as GPU delivery milestones are met. Nvidia: a “strategic partnership” that, with the Microsoft, SpaceXAI, Nscale and Lambda arrangements, gives Anthropic compute powered by Nvidia GPUs.
TSMC and Micron appear in the risk factors as suppliers Anthropic depends on: most advanced chip capacity is “primarily at Taiwan Semiconductor Manufacturing Company”, and high-bandwidth memory is “largely manufactured by SK hynix Inc., Samsung Electronics Co., and Micron Technology, Inc.”.
The public filing already mentions such placements. It says registration-rights agreements give counterparties to certain note purchase agreements the right to register for resale “shares of our common stock issued in connection with certain contractual rights to private placements concurrent with this offering”. Anthropic’s note purchase agreements are with Google, Amazon and Broadcom. Amazon, whose agreement commits Anthropic to spend at least $110.0 billion, is not among the seven companies Reuters names.
The Numbers, by Our Arithmetic
The S-1/A states amounts for seven compute contracts. They are Broadcom $161.2 billion, Google $121.3 billion, SpaceXAI up to $120.5 billion, Amazon $110.0 billion, Microsoft $44.9 billion, Nscale up to about $44.6 billion and Lambda about $41.3 billion. That is $643.8 billion in all, as we set out in Google TPUs Are 44% of Anthropic’s $644B Named Compute Deals. The placement buyers’ share is $327.4 billion, or 50.9%.
On the retracted $70 to $80 terms, $26 billion would buy about 371 million Class N shares at $70 and 325 million at $80. It would be 27.3% of the $95.3 billion raised at $80 counting the IPO, and 30.0% of the $86.7 billion at $70. Those terms are no longer current, and the new range is not public.
The Structural Read
As we read the S-1/A, Class N is the class Anthropic already uses for partners: AMD’s up-to-$5.0 billion commitment is in Class N, and the filing calls Class N holders primarily strategic business partners.
As we read it, the placement adds equity from companies Anthropic pays: Broadcom’s lease rent, Google’s hosting and Microsoft’s compute together equal $327.4 billion of stated commitments, by our arithmetic, against a $26 billion placement for all seven buyers.
Anthropic, PBC S-1/A, 2 November 2026
“While held as Class N common stock, these shares are non-voting and therefore do not impact the voting power of the holders of our Class A common stock”
Three Implications
FOR IPO BUYERS The S-1/A says Class N converts into voting Class A on a registered offering, an open-market sale or a transfer to an unaffiliated third party, and that conversion dilutes Class A voting power.
FOR THE SEVEN BUYERS Reuters reported a combined $26 billion at the IPO price, closing immediately after the IPO; it does not give each company’s share.
FOR THE FOUNDERS The S-1/A says Class A and Class N issuances will not dilute the voting power of the Class F share, which carries a fixed 50.1% of the vote.
The framework argues: “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, the map asks who underwrites the spending; the reported placement shows chip and cloud suppliers buying non-voting equity in a customer that has committed $327.4 billion to three of them, by our arithmetic. The framework predates the report and does not discuss it.
What Is Not Established
The split of the $26 billion among the seven companies, the number of Class N shares they would receive and whether the placement terms changed with the retraction are not in Reuters’ report. The filing copy Reuters saw was not on EDGAR when we checked at 07:16 UTC on 10 November; the public S-1/A of 2 November leaves the price and share counts blank. Anthropic declined to comment to Reuters.
Anthropic’s shares aim to start trading on 19 or 20 November, as we reported. How the raise compares with SpaceX’s is in our earlier piece.
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.
The seven companies Reuters names would buy $26 billion of Anthropic’s Class N stock at the IPO price, which under the S-1/A carries no vote unless the law requires one and becomes voting Class A only on a sale or transfer. Three of them, Broadcom, Google and Microsoft, are on the other side of $327.4 billion of Anthropic’s stated compute commitments, by our arithmetic.
A note on sourcing. The placement, its buyers and the Class N share class are from Reuters’ updated story of 10 November (read in full via CNA syndication), which cites a filing copy Anthropic sent to banks and later said contained inaccurate pricing details. Share-class terms, contract amounts and quotations about them are from Anthropic’s public S-1/A of 2 November on SEC EDGAR. Totals, shares and percentages are our arithmetic. Anthropic was not contacted for this piece.
