Anthropic Before IPO: How DACH Investors Can Now Invest in the Amazon-Backed AI Company

The AI company Anthropic is preparing for an IPO that could take place as early as October 2026. On June 1, 2026, the company filed a confidential S-1 registration with the Securities and Exchange Commission. Sources from September 18, 2026, name October 2026 as the earliest possible date for public listing, with a broader time window through the end of 2026. A public S-1 and a binding date were not yet available at the end of September 2026.

A direct purchase of Anthropic shares via conventional brokerage platforms is currently not possible for private investors in the DACH region. The shares will only become available through regular trading venues after the IPO. Secondary markets for pre-IPO investments exist, but remain closed to most private investors.

Valuation at Record Levels

The latest equity round – the Series H completed on May 28, 2026, for $65 billion – valued Anthropic at $965 billion on a post-money basis. This valuation exceeded OpenAI's most recent valuation at that time, according to a report from July 6, 2026. Source references from September 2026 mention future valuation scenarios of up to $2 trillion.

According to reports from July 6, 2026, the company has achieved "enormous product progress" in 2026, which could enable an earlier IPO than competitors such as OpenAI. OpenAI is reportedly considering waiting until 2027.

Amazon as Major Investor with Billions in Commitment

Amazon is Anthropic's largest financial backer among publicly traded companies. The e-commerce and cloud conglomerate has already invested $13 billion in the AI company, as reported on September 15, 2026. Additional commitments total up to $33 billion, including a fresh financing round of $5 billion from an agreement in April 2026.

Under this agreement, Anthropic committed to spending more than $100 billion on AWS cloud technology in the coming years. According to a report from September 22, 2026, Amazon's Trainium chips are "firmly anchored at Anthropic," and the AI company is working directly with Amazon to improve these chip architectures.

For DACH investors, purchasing Amazon shares (NASDAQ: AMZN) represents the most direct form of indirect participation in Anthropic. Amazon shares are traded on German exchanges and through international brokers, though euro-based investors should consider currency risks.

Other Publicly Traded Shareholders

In addition to Amazon, other technology companies have acquired equity stakes in Anthropic:

• Alphabet (NASDAQ: GOOGL, GOOG) structured a similar stake through equity and contracts with Google Cloud.
• Microsoft (NASDAQ: MSFT) and Nvidia (NASDAQ: NVDA) announced their stakes on November 18, 2025 – Microsoft $5 billion, Nvidia up to $10 billion; Anthropic committed in return to spending at least $30 billion on Microsoft Azure. In the Series H round from May 2026, Anthropic does not list both as investors. Anthropic uses Microsoft Azure for certain workloads and obtains GPU clusters from Nvidia.
• Zoom and Salesforce participated through their respective venture arms, as reported on September 18, 2026.

These stocks are tradable through German brokers and direct banks. Swiss investors can purchase them through local banks or international platforms, as can Austrian investors through domestic custody providers. However, the performance of these securities depends on many more factors than just the success of the Anthropic stake.

Indirect Investment via Exchange Traded Funds

Another option is offered by exchange traded funds that hold pre-IPO shares in companies like Anthropic. These vehicles include the KraneShares Artificial Intelligence & Technology ETF (AGIX) and the ARK Venture Fund (ARKVX). In AGIX, Anthropic made up 1.15 percent of net assets as of September 28, 2026, according to the provider. Such weightings change continuously and should be checked with the provider before investing; the funds typically bundle multiple technology and AI investments.

DACH investors should check whether these funds are accessible through their custody bank and what fee structures apply. Exchange traded funds with pre-IPO positions may have higher administrative costs than classic index ETFs.

Investor Interest at High Levels

A survey by The Motley Fool, whose results were published on September 18, 2026, found that 70 percent of surveyed investors are considering purchasing Anthropic or OpenAI shares at their respective IPOs. This interest explains why investors are already seeking indirect participation routes rather than waiting for public listing.

High demand could lead to a significant stock price increase on the first trading day of a successful IPO. Historically, highly valued tech IPOs often experienced significant volatility in the first few weeks, which is worth considering for risk-conscious investors.

Risks and Classification for Private Investors

While indirect investments through Amazon, Alphabet, or other shareholders provide access to Anthropic's performance, they only partially reflect it. For most publicly listed investors, the Anthropic stake represents only a fraction of the overall company. Accordingly, price changes in Anthropic have little impact on these shares.

Private investors should also note that the $965 billion valuation is based on private venture capital and has not been validated through public market mechanisms. After the IPO, significant valuation adjustments could occur if the company fails to meet high expectations.

For investors from Switzerland, Germany, and Austria, currency risks are an additional consideration for US investments. The exchange rate between the euro or Swiss franc and the US dollar can significantly affect returns, independent of the share price development itself.

Time Window Until IPO

Should Anthropic maintain its intended timeline, DACH investors have only a short window remaining for indirect pre-IPO investments. After public listing, the shares will be directly tradable, but at prices determined by the market.

Whether an investment before or after the IPO makes more sense depends on individual risk tolerance and market conditions at the time of the IPO. Direct purchases after listing allow for a more precise assessment of market reaction, while indirect positions through Amazon and other investors already allow for – albeit significantly diluted – participation now.
