BEHIND THE NUMBERS
What this scenario means for an investor.
This view scales your amount by a change in company valuation. It compares financing milestones; it does not calculate the return on actual shares.
- Your amount vs. the investment minimum
- Your amount sets the size of the illustration. It does not establish the minimum required to join that funding round.
- Access depends on the offering
- Investor eligibility and allocations depend on the offering’s terms. A recorded funding price does not mean everyone could invest at that price.
- Direct shares and fund units differ
- A direct share and a unit in a fund or investment vehicle can have different rights and costs. This scenario does not establish a specific investment route.
- A price is not a cash exit
- Lockups, transfer restrictions and available buyers can affect a holder’s ability to sell. The displayed value does not assume a sale.

Historical post-money company valuations only. Share prices, dilution, security rights, allocation and an IPO exit are not established. These selected milestones are not a claim of the latest valuation.
Calculation: Amount × (ending company valuation ÷ starting company valuation).

Published price precision is retained in calculations. A filing snapshot is not necessarily the investment date. These selected companies and stages do not represent typical private-market results; investments can lose their entire value.

Uses the illustrative amount entered above. A value of 1,000 means $1 trillion. This is your assumption, not a fetched market price.
YOUR ASSUMPTION · NOT AN INVESTMENT RETURN
Enter an assumed valuation to explore the arithmetic.
Formula: amount × (your assumed valuation ÷ reported starting valuation). Company valuation includes financing effects; dilution, share classes, investment access and selling rights are not established. This does not value an actual holding. Assumptions are not added to the evidence register. Choose Save research to keep this scenario in your account.

Compare company valuations, then see how your assumptions change the illustration.
These figures are company valuations, not prices you could necessarily buy or sell at. The unadjusted illustration assumes unchanged proportional participation. Historical dilution, security rights and access remain unknown.
THE EVIDENCE, IN BRIEF
Does this measure an Anthropic investor’s actual return?
The documented mode compares company funding valuations, which include financing effects. It does not establish a shareholder return. To explore per-unit prices, enter both prices, their dates and the same comparable security basis; those prices remain your assumptions.

WHEN YOU WANT TO GO DEEPER
The story behind Anthropic
What this shows
The four reviewed funding announcements include new capital; their valuation changes cannot establish an individual investor’s return.
The endpoint matters
The latest observation in this collection is dated May 28, 2026. It is not a claim about the current valuation. Or enter two comparable private share prices in a separate assumption scenario.
Read it realistically
Your amount is hypothetical. The evidence does not establish your investment minimum, eligibility or ability to sell.

Anthropic describes its work as both AI development and safety research. Claude’s introduction in March 2023 offers a product milestone to place beside the later financing announcements. Funding raised and post-money company value remain separate measures.

These amounts scale by company valuation changes. They are not investor returns and do not establish equivalent securities or historical dilution.

Context to keep in mind
The workbench does not reconstruct historical dilution, preferred rights, allocation minimums or a sale. A funding announcement is not an offer to invest.
CTM interpretation of the linked history and financing evidence; not a complete risk assessment.
What the evidence supports
Historical post-money company valuations only. Share prices, dilution, security rights, allocation and an IPO exit are not established. These selected milestones are not a claim of the latest valuation.
- Investment minimum
- Not verified for these historical entries
- Actual access and allocation
- Not established
- Realized sale proceeds
- Not calculated
- Full funding history
- Not yet compiled; this is selected coverage
What additional research would unlock
A shareholder-return model would need comparable securities, prices, dilution and an appropriate exit or mark—not just company-level valuations.
How to read this company’s calculationAnthropic funding history: comparing three milestones behind Claude
The reviewed observations follow Anthropic’s issuer-announced post-money valuations of $61.5 billion for Series E, $183 billion for Series F and $380 billion for Series G. Their announcement dates run from March 2025 through February 2026. These are selected historical milestones, not a live valuation feed.
The workbench lets you compare reviewed periods using a hypothetical amount. A valuation ratio can illustrate how the headline scale changed, but cannot establish the price or rights of an investor’s shares, historical dilution, or the proceeds from an exit.
Read each announcement alongside its calculation. There are no daily private-market prices between these observations, and we do not invent an intervening price curve. Optional sensitivity inputs are scenarios you choose, not reconstructed historical terms.

Common questions
Is the last milestone Anthropic’s current valuation?
This page makes no claim about the latest valuation. Its reviewed historical coverage ends with the February 2026 Series G announcement.
Can I use the result as a return on Claude or Anthropic shares?
No. Claude is the product associated with Anthropic, and this comparison uses company-level funding valuations. It does not establish a tradable security, investor access, dilution or actual returns.
Does this include an IPO exit?
No. The endpoints are funding valuation announcements. An IPO price and a realizable sale are not modeled.

What’s missing matters.
There are no daily private-market prices between these observations. We do not fill the gaps with an invented curve. Investment returns require the specific security, entry terms, dilution and an actual exit or appropriate mark.
