Anthropic IPO Subscription Guide: How to Invest in the AI Trillion-Dollar Giant by 2026?
Abstract
With Anthropic officially filing its S‑1 registration statement confidentially with the U.S. Securities and Exchange Commission (SEC) on June 1, 2026, this AI "super unicorn," valued at up to $965 billion, has become a global focal point. From the perspective of Hong Kong investors, this article dissects its business landscape—part of a "dual-cloud ecosystem" alongside Amazon and Google—and its position in the "trillion-dollar IPO race" alongside OpenAI and SpaceX. If Hong Kong investors are bullish on Anthropic, they can participate in its investment through the following three key avenues:
Direct IPO subscription: Open an account and allocate funds in advance with a brokerage that supports U.S. stock IPOs, and participate in the offering as soon as it becomes available.
Concept‑stock positioning: An analysis of the synergistic effects among core shareholder Amazon (AMZN), strategic partner Alphabet (GOOGL), and leading computing‑infrastructure player Nvidia (NVDA).
Industry ETFs: Invest via ETFsDiversified investmentand remain vigilant about the risk of "valuation markdowns" in certain channels following the IPO.
This guide will provide an in-depth analysis, from a financial perspective, of Anthropic's investment appeal, its IPO progress, and the strategic positioning options currently available to Hong Kong investors.
Latest Updates on Anthropic's IPO
According to Reuters, Anthropic secretly filed a Form S‑1 with the SEC on June 1, 2026, officially kicking off its U.S. IPO. The company stated that the timing of the listing remains subject to SEC review and market conditions, and that the number of shares to be issued and the pricing range have yet to be determined.
Earlier, on May 28, Anthropic closed its Series H funding round, raising $65 billion and achieving a post‑money valuation of $965 billion—surpassing OpenAI's roughly $852 billion at the same stage and making Anthropic the world's highest‑valued AI startup. The company's annualized revenue run rate has now exceeded $47 billion, and enterprise adoption of Claude continues to accelerate.
Bloomberg, citing sources familiar with the matter, reports that Anthropic, along with SpaceX and OpenAI, is set to join a "trillion-dollar IPO wave" in 2026. The market broadly expects the listing window to open in the second half of 2026 or early 2027, though the official ticker symbol has yet to be announced.

Why should Hong Kong investors pay attention to Anthropic?
Anthropic was founded in 2021 by former core members of OpenAI, with a mission to build AI systems that are "reliable, interpretable, and controllable." Its flagship Claude series of models has seen accelerating adoption in enterprise‑level applications—such as customer service, automated workflows, knowledge management, and software collaboration—and Claude Code has become a breakout tool within developer communities.
Compared with some AI companies that emphasize general-purpose capabilities and consumer traffic, Anthropic's positioning is more inclined toward:
Corporate Compliance and Controllable Risks
Security and Traceability ("Constitutional AI" Technological Roadmap)
Long-term sustainable B2B commercialization
This strategic positioning enables it to wield greater bargaining power in highly regulated sectors such as finance, healthcare, law, and the public‑private sector.
Anthropic's "Dual-Cloud Ecosystem"
Amazon (AMZN.US) and Google (GOOGL.US) are the "dual engines" of Anthropic's business strategy. Unlike a single-cloud dependency, Anthropic adopts a dual-cloud parallel approach—AWS plus Google Cloud—both to diversify vendor risks and to make the two tech giants simultaneously shareholders and infrastructure partners:
Amazon: With cumulative investments exceeding $8 billion and an approximately 18% stake, the Claude model is deeply integrated with AWS Bedrock, while Anthropic has also pledged to invest over $100 billion in computing resources on AWS over the next decade.
Google: Through multiple rounds of investment, it holds approximately 14% of the equity (as disclosed in public documents from the U.S. Department of Justice's antitrust case). Meanwhile, Anthropic is a key customer of both Google Cloud and TPU chips, creating a "coopetitive" relationship—Gemini is its competitor, yet Anthropic also serves as a strategic ally.
This unique structure implies that Anthropic's IPO is not merely a capital event for a single AI company; it could also trigger a revaluation of the hundreds of billions of dollars in market capitalization held by Amazon and Google, with the entire AI industry chain undergoing a reassessment.
Investment in the Trillion-Dollar AI Market
In the past, investors seeking exposure to leading AI companies often had no choice but to turn to compute‑power providers like Nvidia or indirect targets such as Microsoft (a partner of OpenAI). Anthropic's IPO will directly introduce a near‑trillion‑dollar "safe AI powerhouse" to the secondary market. Backed by its differentiated "Constitutional AI" moat, an enterprise‑revenue run rate in the $47 billion range, and deep integrations with the two cloud giants, Anthropic's listing is poised to trigger a revaluation of the entire enterprise‑AI sector across global capital markets.
Anthropic's IPO Investment Strategy
Since Anthropic has not yet officially listed on the NASDAQ or NYSE, it is currently not possible to purchase its shares directly through Futu. However, if Hong Kong investors are optimistic about Anthropic, they can make early arrangements using the following three methods:
Strategy One: Direct Participation in the IPO
This is the most direct way to capture the maximum potential upside. Once the relevant IPO officially opens for subscription, investors can be ready to participate in U.S. stock IPOs right away.
It's worth noting that Futu holds a very high market share in the U.S. stock IPO space and has previously been deeply involved in underwriting and distributing popular U.S. stocks such as Gemini, Figure, Circle, and Medline.
Hong Kong investors, due to time‑zone differences, cannot monitor U.S. stock markets continuously. Meanwhile, new issues often experience sharp price swings on their first trading day, leaving those who fail to keep up with real‑time updates vulnerable to missing out on gains or being unable to execute timely stop‑loss orders. By using trailing stop‑limit orders, you can set a "drawdown percentage" to manage significant market volatility.
If Anthropic's share price surges on its first day due to heightened market enthusiasm, the system will automatically raise the trigger price to prevent you from missing out; once the stock price falls back into the preset range from its peak, the system will automatically sell to lock in losses. Even while you're asleep, it can precisely safeguard your gains and prevent profit erosion.
For example: Suppose the IPO price of Anthropic is 80. On the first day, the stock opens with a surge of 2,580%, then surges another 25,100% at the open, exhibiting strong upward momentum, though the timing of its pullback remains uncertain. We can place a trailing stop-limit order, setting the trailing amount to 5, with a specified spread of 5 and another specified spread of 1.
Scenario 1: When the stock price rises to 110, the trailing stop-loss is automatically adjusted upward to 110. If the price subsequently falls back to 105, the system will automatically place a limit sell order at 104—calculated as 105 − 105 − 1 (the specified spread)—to lock in the floating profit of 25 and prevent any loss of gains.
Scenario 2: If the stock price continues to rise to 120, the stop-loss level will move up in tandem to 120, and then further to 115, continuously locking in additional gains.
The entire process requires no manual intervention, effectively mitigating the risk of selling at a loss while reasonably capping downside losses.
Pre-Subscription Checklist:
Open an account in advance: Choose a brokerage that supports U.S. stock IPOs and complete the KYC process.
Early fund deposit: Reserve your Hong Kong dollar–to–U.S. dollar exchange rate in advance to avoid last-minute rush during the subscription period.
Set reminders: Follow the S-1 public offering, roadshow, pricing, announcement of winning lottery numbers, and listing date.
Set a capital cap: Don't go all-in; predefine your maximum acceptable drawdown.
Plan your trading strategy: Clearly decide whether to focus on "short-to-medium-term IPO investing" or "medium-to-long-term holding."
Strategy Two: Allocate to "Anthropic Concept Stocks"
Core Shareholders and Strategic Partners: Going public is a "boost" for shareholders.
$Amazon(AMZN.US)$
Amazon is Anthropic's largest single shareholder, having invested a cumulative total of over $8 billion, with an additional $5 billion committed in April 2026 and a pledge to invest up to $20 billion in milestone‑based funding. At a valuation of $965 billion, Amazon's stake could be worth more than $170 billion. Even more significantly, Anthropic has pledged to invest over $100 billion in AWS over the next decade—locking in not only equity gains but also long-term cloud‑revenue streams for AWS. For Amazon, Anthropic's IPO would mean a substantial revaluation of its holdings at market prices, while continuing to drive high‑quality enterprise customer revenue for AWS.
Google holds approximately 14% of Anthropic's equity (as confirmed by public documents in the U.S. Department of Justice's antitrust case), with its stake valued at roughly $135 billion based on the latest valuation. Google also serves as Anthropic's provider of Google Cloud services and TPU chips, creating a three‑pronged strategic alignment that integrates investment, infrastructure, and distribution. Although Gemini and Claude compete with one another, Anthropic's planned IPO would bring Google's previously intangible AI assets into clear market pricing for the first time, potentially acting as an implicit catalyst for GOOGL's stock price.
Nvidia is the core provider of computational power for Anthropic's model training. As Anthropic's annualized revenue surpasses $47 billion and it continues to expand its GPU procurement, Nvidia's role as a "shovel seller" becomes equally clear: each expansion by this trillion-dollar AI giant translates into a corresponding surge in GPU orders.
Key Competitors: Industry Momentum vs. Capital Diversion
As Anthropic's valuation rises, competitors in the AI space may benefit from heightened industry enthusiasm. However, over the medium to long term, if Anthropic successfully goes public, some capital could shift away from purely speculative plays and gravitate toward the "real deal."
Viewed by the market as OpenAI's "super‑agent," it has deeply integrated ChatGPT into its ecosystem through Azure cloud services and the Copilot product line. If Anthropic delivers a strong IPO performance, it could intensify the valuation race among AI industry leaders, potentially boosting sentiment across the broader AI sector in the short term; however, over the longer term, investors may face pressure to choose sides between OpenAI and Anthropic.
This stands in stark contrast to Meta's open-source Llama model and Anthropic's "secure, closed‑source" approach. Meta's strengths lie in its consumer‑level traffic and ad‑monetization capabilities, while its weakness is the depth of its penetration into enterprise‑compliant use cases. Anthropic's IPO could reinforce the narrative that "enterprise AI equals secure and controllable," thereby exerting indirect pressure on Meta's B2B expansion.
Viewed by some investors as a "pure-play enterprise‑level AI stock," it focuses on deploying AI applications in industrial and government‑enterprise settings. Compared with Anthropic, its scale is vastly different, but if a trillion‑dollar‑valued AI IPO ignites sector-wide enthusiasm, mid‑ and small‑cap stocks like C3.ai could see a "herd‑following rally." Conversely, should capital concentrate on Anthropic itself, the volatility risk of these "substitute" stocks also warrants close attention.
Strategy Three: Invest in AI Industry ETFs and Private Equity Channels
If you're unable to directly participate in Anthropic's IPO for now, consider diversifying your AI‑related investments through ETFs to mitigate the risks associated with any single stock. Compared with betting on a single new issue, thematic ETFs can simultaneously cover multiple segments—such as computing power, cloud services, and software applications—making them ideal for investors who wish to tap into the AI sector's upside before Anthropic lists.
Anthropic operates in the enterprise‑level AI sector, which is closely tied to a range of industry‑wide concepts—from underlying computing infrastructure and cloud‑based distribution platforms to the deployment of generative AI applications. By investing in ETFs that track these diverse themes, you can gain indirect exposure to the sector's growth driven by the accelerating commercialization of AI, even without directly holding Anthropic shares.

Shareholder Revaluation Effect: The market capitalization of core shareholders' holdings in companies such as Amazon and Google will be revalued.
Risk
Overvaluation risk: Over 14 months, the company's valuation surged from $61.5 billion to $965 billion—roughly a 15.7‑fold increase—suggesting that the IPO pricing may have already priced in future expectations.
Competitive Risks: OpenAI, Google Gemini, and Meta's Llama models are undergoing rapid technological iteration, leading to intense competition for market share.
Regulatory Risk: The AI regulatory framework is still evolving, giving rise to policy uncertainty.
Profitability Validation Risk: With substantial R&D and computing‑power expenditures, the timing of a profitability inflection point remains uncertain.
Private‑equity‑channel valuation impact: Stocks such as DXYZ and VCX may see their premium significantly narrow following Anthropic's IPO.
Conclusion
Anthropic's IPO is undoubtedly one of the most anticipated financial events of 2026, yet its timeline remains shrouded in uncertainty due to SEC scrutiny and broader market conditions. For investors at large, the prudent approach remains patience—keeping a close eye on the company's progress, particularly its revenue growth trajectory and the emergence of a sustainable inflection point in profitability.
Rather than anxiously waiting for an uncertain date, use this time to do your homework: gain a deep understanding of the AI‑security sector's potential, assess your own risk tolerance, and craft a clear investment strategy. Whether you're preparing for Anthropic's IPO itself, or choosing to invest in its key shareholders—Amazon, Google—or in related ETFs and private‑equity vehicles, getting ahead now will give you a competitive edge in the trillion‑dollar AI investment wave. Remember: opportunity always favors the prepared.
