Sequoia Capital is joining Anthropic's blockbuster funding round, breaking a decades-old Silicon Valley taboo against backing competing companies in the same sector. The move positions the storied VC firm as the only major investor with stakes across all three leading AI labs: Anthropic, OpenAI, and Elon Musk's xAI.

The Claude-maker is now targeting up to $25 billion in a round that would value the company at $350 billion—more than double the $170 billion valuation it achieved just four months ago.

Singapore's sovereign wealth fund GIC and Coatue Management are leading the financing with $1.5 billion each. Microsoft+0.70% and Nvidia-0.51% have already committed up to $15 billion combined, with other VCs and investors contributing another $10 billion or more. The round is expected to close within weeks.

The $1 Trillion AI Club

The funding crystallizes the AI industry's extraordinary concentration of capital. The three leading U.S.-based foundation model companies now command a combined valuation exceeding $1 trillion:

xAI closed its own $20 billion round earlier this month, exceeding its $15 billion target with backing from Nvidia, Cisco, Fidelity, and the Qatar Investment Authority. OpenAI has opened talks for a funding round that could value it at $750 billion.

Sequoia Breaks the Rules

Sequoia's decision to back Anthropic is particularly striking given the firm's historical stance on portfolio conflicts. In 2020, the firm took the extraordinary step of walking away from its investment in payments company Finix after determining the startup competed with Stripe—forfeiting $21 million and giving up its board seat, information rights, and shares.

The reversal signals that the potential upside in AI foundation models is too significant to bet on a single winner. Sequoia now joins Nvidia, ARK Ventures, and Fidelity as firms backing all three leading AI labs.

The move also raises questions about access to confidential information. OpenAI CEO Sam Altman testified last year that investors with ongoing access to OpenAI's confidential information were told that access would be terminated "if they made non-passive investments in OpenAI's competitors"—a standard protection against misuse of competitively-sensitive data.

The Investor Lineup

Anthropic's investor base now spans the full spectrum of global capital:

Tech Strategic Partners:

• Microsoft+0.70% — Up to $10 billion; Anthropic models now available on Azure and integrated into Microsoft 365 apps and Copilot
• Nvidia-0.51% — Up to $5 billion; strategic alignment on AI compute and infrastructure

Lead Financial Investors:

• GIC (Singapore) — $1.5 billion; sovereign wealth fund seeking AI exposure
• Coatue Management — $1.5 billion; leading tech-focused hedge fund

Cloud Partners:

• Amazon+0.39% — $8 billion total ($4B initial + $4B expansion); Anthropic is AWS's primary AI partner through Bedrock
• Alphabet-0.84%/Google — Early investor; Claude available on Google Cloud's Vertex AI

The Microsoft-Nvidia-Anthropic partnership announced in November includes Anthropic purchasing $30 billion in cloud computing capacity from Microsoft Azure, creating deep operational ties between the companies.

Revenue Trajectory Justifies Valuation

Anthropic's valuation expansion reflects extraordinary revenue growth. The company reached approximately $7 billion in annualized revenue in October 2025, up from roughly $1 billion at the end of 2024—a 7x increase in under a year.

Enterprise customers drive approximately 80% of Anthropic's revenue, with more than 300,000 business customers worldwide. Claude Code, the company's coding assistant launched earlier this year, has reached nearly $1 billion in annualized revenue alone.

The company projects it will stop burning cash in 2027 and reach break-even in 2028, with internal projections showing up to $70 billion in revenue and $17 billion in cash flow by 2028.

What It Means for Public Markets

The Anthropic funding has ripple effects across multiple public companies:

Microsoft+0.70% ($3.4 trillion market cap) — Microsoft's investment in Anthropic diversifies its AI strategy beyond its partnership with OpenAI. The company is now the only major cloud provider with deep partnerships across both leading AI labs. Claude models are available on Azure and integrated into Microsoft 365 apps and Copilot.

Nvidia-0.51% ($4.5 trillion market cap) — Nvidia's investment in Anthropic follows its stake in xAI, positioning the chipmaker as the dominant supplier to all three leading AI labs. With AI compute remaining the critical bottleneck, Nvidia's strategic investments ensure continued demand for its GPUs.

Amazon+0.39% ($2.5 trillion market cap) — Amazon's $8 billion investment makes it Anthropic's largest backer. Claude is the flagship model on Amazon Bedrock, AWS's fully managed AI service, giving Amazon a competitive answer to Microsoft's OpenAI partnership.

Alphabet-0.84% ($4.0 trillion market cap) — Google was an early Anthropic investor, but the company's own Gemini models now compete directly with Claude. The relationship has become more complicated as Anthropic grows into a direct rival.

IPO on the Horizon

The funding round comes as Anthropic prepares for a potential public offering. The company hired law firm Wilson Sonsini in late 2025 to prepare for an IPO that could take place as early as 2026.

If Anthropic proceeds at its current valuation, it would rank among the largest tech IPOs in history, rivaling or exceeding Alibaba's $25 billion offering in 2014. The company's path to profitability by 2028 and explosive revenue growth could make it an attractive public market candidate.

What to Watch

Near-term catalysts:

• Round closure (expected within weeks)
• Potential IPO filing in H1 2026
• Q4 2025 revenue milestone ($9B ARR target)

Competitive dynamics:

• OpenAI's next funding round (potentially $750B valuation)
• Enterprise adoption rates for Claude vs. ChatGPT
• Impact of Microsoft's multi-lab strategy on OpenAI relationship

Regulatory considerations:

• FTC scrutiny of tech giants' AI investments
• EU AI Act implementation affecting foundation model providers
• Potential restrictions on sovereign wealth fund investments in U.S. AI companies
