How is an Anthropic pre-IPO trade settled?
If the position is held through to the listing, settlement is based on the official market capitalisation on the first trading day. The relevant share price is the closing price that day, as specified in the settlement calculation. The specific terms of IG’s Anthropic pre-IPO market apply.
Put simply, what matters is Anthropic’s actual valuation at the end of its first stock market session. If it is above the level at which a trader entered a long position, that would be positive before costs. If it is below, that would be negative. For a short position, the logic is reversed.
Example:
A trader opens a long position at an IG quote of 2,000, representing an expected valuation of US$2.0 trillion. At the close of the first official trading day, the relevant market capitalisation is US$2.2 trillion. In this simplified example, the valuation has moved US$200 billion above the entry level.
If the final valuation is instead only US$1.8 trillion, the market has moved US$200 billion below the entry level. That would be negative for a long position and positive for a short position.
The trader’s own profit or loss is calculated from the difference in points and the position size, less applicable costs. A US$200 billion change in the company’s valuation therefore does not represent the trader’s profit or loss.
Why does a pre-IPO market move before the listing?
Since Anthropic is not yet publicly listed, there is no daily traded share price. The pre-IPO market therefore relies on expectations, estimates and new information surrounding a potential flotation.
According to reports, marketing of Anthropic’s IPO is expected to begin in mid-October 2026 at the earliest. An exact official date for the first trading day has not yet been set. This timetable reflects reported plans and may change.
The company has already taken a formal step: on 1 June 2026, Anthropic submitted a confidential draft registration statement on Form S-1 to the US Securities and Exchange Commission. A flotation remains subject to completion of the SEC review, market conditions and other factors.
Important influences include:
-
Publication of the public S-1 prospectus, new funding rounds, business updates, progress with Claude and Claude Code, regulatory developments, institutional demand, sentiment towards technology stocks and potential IPO delays.
-
For a company such as Anthropic, these factors can have a strong impact. Beyond the existing business, the valuation may reflect future opportunities in AI-assisted software development, automated workflows and the use of AI agents in businesses.
-
In May 2026, Anthropic announced a US$65 billion funding round at a US$965 billion post-money valuation. This private funding valuation provides a reference point for investors; it does not determine the eventual IPO valuation.
Why is Anthropic a particularly interesting pre-IPO market?
Anthropic interests traders because the company brings together several applications of artificial intelligence. Claude supports knowledge work and business tasks. Claude Code is aimed at software development. Wider adoption of these applications in businesses creates further growth opportunities.
This combination also carries risks. The higher the expected valuation, the more future success Anthropic needs to deliver. From an investor’s perspective, the question is therefore whether increasing usage translates into an economically sustainable business. High computing and development costs, as well as competition between AI providers, could weigh on those expectations.
The pre-IPO market makes it possible to trade this uncertainty. The central question is whether Anthropic’s expected valuation is too high, too low or fair. Even positive company news may not justify a high entry price if it already incorporates even greater expectations.
Trade other pre-IPO markets with IG
Anthropic is just one example. Depending on market availability, IG traders can also take positions on other private companies, such as OpenAI, Canva, Discord or Strava, through pre-IPO markets. The principle is always the same: traders deal on the expected valuation at the stock market debut, rather than the future shares.
Conclusion: Trade Anthropic before its IPO and understand what you are trading
IG’s Anthropic pre-IPO market gives traders the opportunity to take a position on the company’s expected market capitalisation before a potential flotation. It allows them to express a valuation view before the shares begin trading officially on an exchange.
The key point is that traders do not buy Anthropic shares. They do not participate in the IPO subscription process or receive a share allocation. Instead, they trade a position on the company’s expected valuation.
This may interest traders because expectations for Anthropic can change significantly ahead of its market debut. At the same time, the market is speculative, news-driven and carries substantial risks. With CFDs, leverage amplifies both gains and losses. Anyone considering trading Anthropic before its IPO should therefore understand the development of its business and how the pre-IPO market works.
