Anthropic’s Nasdaq filing points to an offering of up to $100 billion

Anthropic’s filing for a Nasdaq offering says the sale could bring in as much as $100 billion, a ceiling rather than a statement of proceeds already raised.¹ That possible amount exceeds the $86 billion record attributed to SpaceX, which was set in June 2026.¹ The comparison places Anthropic’s prospective sale above the cited benchmark, while the filing’s wording leaves the ultimate size uncertain.¹ Bloomberg Technology characterized the planned listing as potentially among the largest public debuts ever, a description that reflects the scale implied by the filing rather than a completed transaction.¹²

The scale of the proposed offering is paired with a valuation range that would put Anthropic at $1.5 trillion to $2 trillion after an IPO, according to the filing.¹ Earlier this year, private investors valued the company at $965 billion, making that figure a prior valuation rather than the post-IPO range.¹ The filing therefore points to a higher valuation than the earlier private-market figure, but it presents a prospective range rather than a final price.¹ The offering amount and valuation describe different things: one is a possible sum raised through the sale, while the other estimates the company’s value after the listing.¹

Anthropic reported a first-half 2026 net loss of $80.7 billion, a sharp increase in its losses.¹ The comparable first-half figure a year earlier was $13 billion, so the newer reported loss is substantially larger than the earlier one.¹ The comparison concerns losses in the first halves of two successive years, not a comparison between a half-year result and a full-year result.¹ Revenue moved in the opposite direction in the sense that the filing reports first-half 2026 revenue at more than three times Anthropic’s total revenue for all of 2025.⁵

Those revenue periods are not equal in length: one covers the first half of 2026 and the other covers all of 2025, so the comparison is not between two full-year totals.⁵ The reported expansion in first-half revenue and the larger first-half net loss are both part of the picture presented by the filing, but they measure different financial outcomes.¹⁵ The revenue figure compares sales over the stated periods, whereas the loss figure records the reported net loss for each of the two half-year periods.¹⁵ Neither comparison, on its own, supplies a full-year 2026 revenue or loss figure, because the cited results cover only the first half of that year.¹⁵

The filing names several sources of risk, including regulatory obstacles, the challenge of keeping staff, and obtaining enough computing resources.¹ It also lists the possibility of catastrophic or existential harm to humanity among the risks facing the company.¹ These disclosures place operational, regulatory and safety concerns alongside the offering’s proposed scale and the financial results reported for 2026.¹ The filing identifies these matters as risks; the cited information does not quantify their likelihood or specify what effect any one of them would have on the offering.¹

The safety language follows a September 2026 essay by chief executive Dario Amodei, in which he called on the industry to slow its progress for safety reasons.¹ The filing’s inclusion of severe safety risks can be read alongside that earlier public appeal, though the facts provided do not establish that the essay caused the filing’s wording.¹ The sequence is that the essay came in September 2026 and the filing followed it; the cited facts do not give a more exact filing date.¹ That chronology links the company’s safety discussion in its filing to a prior statement from its chief executive, without resolving how the company will address the listed risks.¹

Anthropic is also in a legal dispute with the Pentagon over a designation that treats the company as a supply-chain risk.¹ The case has produced differing rulings in two courts, and both sides have appealed.¹ That dispute bears on the regulatory concerns listed in the filing, but the available facts do not describe the rulings’ reasoning or predict the appeals’ result.¹ The legal contest is therefore an existing issue alongside the prospective public offering, not a resolved matter described by the filing.¹

The prospectus says banks managing the offering may distribute Class A common shares to customers of their online brokerages.⁵ It names Morgan Stanley/E*TRADE as a possible channel for that allocation, not as a confirmed route for every share or every customer.⁵ This provision concerns how some shares might reach brokerage customers, while the possible $100 billion figure concerns the maximum amount the offering could raise.¹⁵ The prospectus describes a possible allocation arrangement; it does not, in the cited information, state how many customers would receive shares or how many shares any customer might be offered.⁵

U.S. markets rose on the day of the filing, and the Nasdaq Composite finished at 26,169.38 after gaining 214.04 points, or 0.82%.⁴ Those figures describe the index’s daily movement and closing level, not a change in Anthropic’s valuation or the proceeds it could raise.¹⁴ Taken together, the filing presents a potential offering larger than the cited prior record, a post-IPO valuation above the earlier private figure, rapid revenue growth against a full-year comparison, and a much larger first-half loss.¹⁵ It also sets out company-specific legal, staffing, computing and safety concerns, while the market rise on filing day supplies a separate measure of that day’s broader trading context.¹⁴
