Anthropic shares are trading at approximately $572 per share on secondary markets as of late May 2026, reflecting a company valuation exceeding $590 billion—a substantial premium above the $380 billion post-money valuation from the company’s $30 billion Series G funding round concluded in February 2026. The AI research firm is now in active discussions with major investment banks including Goldman Sachs, JPMorgan Chase, and Morgan Stanley to launch a public offering targeting October 2026, expected to raise above $60 billion based on analyst projections.

Anthropic’s Rapid Ascent From Startup to Tech Giant in Two Years

Anthropic PBC has achieved one of the most aggressive venture capital trajectories in AI history. Founded in 2021 by former OpenAI researchers including Dario Amodei and Daniela Amodei, the company introduced Claude, its flagship AI assistant competing directly with ChatGPT. In less than five years, Anthropic progressed from a stealth-mode startup to a unicorn, then a decacorn, and now a company valued above half a trillion dollars on private markets. This valuation trajectory reflects confidence in the company’s Claude AI model family, which has gained significant adoption among enterprise customers and individual users seeking alternatives to other large language models.

Anthropic’s revenue growth rate demonstrates why secondary market investors are pricing the company at a substantial premium. The company generated approximately $1 billion in annualized revenue at the start of 2025, reached $14 billion in annual run rate by the end of Q1 2026, and is tracking toward $40+ billion annualized revenue based on recent quarterly performance. This 1,400% growth in one year places Anthropic among the fastest-scaling technology companies ever, surpassing the early-stage growth rates of OpenAI, Stripe, and most U.S. software companies.

Secondary Market Valuations Reveal Significant Investor Optimism

The $572 per share valuation represents a critical data point—one that tells a story of investor expectations diverging sharply from the company’s most recent primary round valuation. Notice.co estimated Anthropic stock at $572.41 as of May 28, 2026, while Nasdaq Private Market valued shares at $550.97 as of May 12, 2026. Other platforms including Hiive reported even higher prices around $1,303 per share, indicating significant price variance across secondary market venues—a common occurrence in illiquid, pre-IPO securities where information asymmetry and limited trading volume create wider bid-ask spreads.

The roughly $1.5x premium from February’s $380 billion valuation (calculated at approximately $380 per share based on secondary market conversions) to May’s $572 per share reflects several factors. First, Anthropic’s explosive Q1 2026 revenue performance—$4.8 billion—exceeded many analyst expectations and demonstrated the company’s ability to monetize its Claude AI models at enterprise scale. Second, competitive pressures from OpenAI, Google’s Gemini, and other AI providers have intensified, making Anthropic appear relatively more valuable as a standalone alternative. Third, IPO anticipation often drives secondary market premiums as early investors seek liquidity before public markets open.

Revenue and Financial Performance Suggest IPO-Ready Status

Metric	2024 (Baseline)	Q1 2026	Run Rate Trajectory
Annualized Revenue	~$1 Billion	$4.8 Billion	$19.2B+ (annualized)
Projected Q2 2026	—	+100% QoQ	~$10.9B quarterly
Operating Margin	Negative	TBA	~70% estimated
Total Funding Raised	~$35 Billion	$68.15 Billion (cumulative)	11 funding rounds completed

Anthropic’s financial trajectory supports the October 2026 IPO target outlined in recent Wall Street Journal reporting and confirmed by multiple individuals familiar with company planning. According to CNBC sources, Anthropic is anticipated to achieve profitability in the near term—a critical milestone for IPO-stage companies. The company benefits from high gross margins on its Claude API and enterprise offerings, with reported operating margins approaching 70% on incremental revenue once infrastructure scaling plateaus. This profitability trajectory contrasts sharply with OpenAI, which continues to operate at losses despite significant revenue, underscoring Anthropic’s unit economics advantage in the competitive AI market.

The IPO environment for software and technology companies in late 2026 appears favorable by historical standards. Global IPO activity is recovering, and mega-IPOs like SpaceX (expected $75+ billion raise) and potential OpenAI public offerings have created investor appetite for large-scale technology flotations. Anthropic’s $60+ billion target raise would rank among the largest tech IPOs ever, exceeding Facebook’s $16 billion (2012), Alibaba’s $25 billion (2014), and positioning alongside historical mega-IPOs.

Critical Path to October IPO and Open Questions on Valuation

Anthropic faces several non-trivial milestones before a late 2026 public listing materializes. The company must finalize S-1 registration statements with the SEC, undergo audits of financial statements (expanded beyond historical limited audits), and obtain final pricing guidance from Goldman Sachs, JPMorgan, and Morgan Stanley. Market conditions, regulatory scrutiny of AI—a focus area for multiple government agencies—and competitive announcements from OpenAI or other AI firms could shift the October timeline. Sources familiar with Anthropic’s board have indicated flexibility around timing, with late October 2026 as the target but potential for Q1 2027 execution if market conditions or regulatory clarity warrant delay.

A critical open question concerns the public market valuation. Will secondary market prices at $572 per share (or higher) persist into the IPO? Historically, pre-IPO secondary market valuations overshoot public market opening prices due to lack of liquidity and the winner’s curse—buyers in secondary markets often overpay expecting easy exits at IPO. Facebook’s secondary market traders paid up to $38 per share before the company’s 2012 IPO at $38 (later declining), while Uber’s pre-IPO secondary markets valued the company substantially higher than its 2019 IPO price. Anthropic’s October IPO could see a $400-$450 opening range, or conversely $600+ if revenue continues accelerating and profit margins expand as anticipated by insiders.

“Anthropic leads OpenAI in business growth with a $44B ARR and 70% margins. Despite OpenAI’s $852B value, high costs and IPO delays loom as competitive risks.”

The Broader Market Impact of a Multi-Trillion-Dollar AI IPO Wave

Anthropic’s IPO, alongside anticipated public offerings from SpaceX (valued at $210+ billion in recent private rounds), OpenAI (internal valuation discussions exceeding $850 billion), and enterprise AI platforms like Databricks, could reshape capital markets in the final quarter of 2026. Combined demand for these mega-IPOs is estimated between $100-$200 billion by analysts—dwarfing the entire 2025 U.S. IPO market of $42.6 billion across 251 transactions per KPMG. This capital reallocation will likely redirect investment dollars from traditional tech, healthcare, and energy sectors into AI-focused businesses.

Anthropic’s success in reaching profitability before going public—if confirmed—marks a watershed moment for the generative AI industry. Unlike OpenAI, which invested heavily in custom chip development and infrastructure to reduce NVIDIA dependence, Anthropic has maintained disciplined capital allocation while achieving superior revenue growth. This operational excellence, combined with Claude’s reputation for safety and instruction-following compared to competing LLMs, positions Anthropic as a credible alternative governance story in an industry increasingly scrutinized by regulators.

What Secondary Market Pricing Reveals About AI Investor Expectations

The $572 per share valuation on Anthropic stock as of May 28, 2026, grounded in verified transactions across Notice.co, Nasdaq Private Market, and Hiive platforms, telegraphs investor conviction: the enterprise demand for Claude AI and Anthropic’s foundational models is real, durable, and growing faster than internal company projections. Secondary market participants—including employees with liquidity events, early-stage venture investors rolling positions, and later-stage hedge funds—are voting with capital that Anthropic deserves a $590+ billion market capitalization, representing roughly 1.55x the February Series G post-money valuation. The question before public markets in October 2026 is whether retail and institutional investors will affirm or discount that valuation upon opening day trading.

The path forward depends on several variables: continued acceleration of Claude API adoption, evidence of profitable unit economics at scale, successful navigation of regulatory scrutiny on AI safety and data usage, and the relative positioning of Anthropic against OpenAI, Google, Meta, and emerging Chinese AI competitors. For investors considering secondary market entry before the IPO, the $572 per share price captures current market expectations—but assumes successful October 2026 IPO execution and sustained revenue growth. Any delays, competitive setbacks, or margin compression would likely pressure secondary market valuations downward before correction upward at IPO pricing.
