Anthropic tightens investment terms amid high demand for shares
The burgeoning artificial intelligence landscape of 2025 continues to be defined by intense investor interest, and at its epicenter stands Anthropic, the developer behind the Claude large language models. Facing an insatiable demand for its shares, the company is reportedly moving to dictate increasingly stringent terms for investment, particularly clamping down on certain types of investment vehicles. This strategic move underscores Anthropic’s powerful position in a market where venture capitalists are tripping over themselves to participate.
The heightened scrutiny over investment comes as Anthropic experiences explosive growth. The company’s annualized revenue has remarkably tripled from $1 billion to $3 billion in a mere five months, spanning the first quarter to May 2025, largely fueled by a voracious demand for its code-generation capabilities within the business-to-business (B2B) sector. This rapid expansion has positioned Anthropic to project annual revenues of $3.7 billion by the close of 2025, with an ambitious forecast of reaching $34.5 billion by 2027. Unlike some competitors who rely heavily on consumer subscriptions, Anthropic has strategically embedded its AI models into the workflows of major enterprises, including companies like T-Mobile and Morgan Stanley, demonstrating a clear focus on the lucrative enterprise market.
This extraordinary growth has naturally drawn significant investment, placing Anthropic firmly in the driver’s seat when it comes to negotiating terms. The company’s latest major funding round, a $3.5 billion Series E completed in March 2025, valued the firm at an impressive $61.5 billion. This round saw participation from prominent investors such as Lightspeed Venture Partners, Bessemer Venture Partners, Cisco Investments, and Menlo Ventures, among others. Beyond this, Anthropic has garnered substantial backing from tech giants, with Amazon investing up to $8 billion and Google committing $2 billion. Most recently, a report from late July 2025 indicated that Anthropic was nearing completion of a $550 million funding round that could potentially push its valuation to an eye-popping $170 billion, further illustrating the immense investor appetite.
The “clamping down” largely targets Special Purpose Vehicles (SPVs), which are often used by smaller investors or syndicates to pool funds and invest in private companies. By imposing stricter terms on these vehicles, Anthropic aims to maintain greater control over its cap table, ensuring that new investments align with its long-term strategic vision and that its shareholder base remains composed of desirable, often larger and more strategic, partners. This move reflects a broader trend within the company of managing overwhelming demand for its resources; for instance, Anthropic recently implemented weekly usage caps for its AI coding tool, Claude Code, affecting a small percentage of its power users due to surging service demand and resource allocation challenges. Similarly, the company updated its overall Usage Policy in August 2025 to reflect evolving capabilities and address new risks, indicating a systematic approach to managing its expanding influence and technological power.
The broader AI industry is currently experiencing what many are calling an “AI Gold Rush,” with U.S. startup funding surging by 75.6% in the first half of 2025, predominantly fueled by AI investments. Major funding deals in August 2025 for other AI startups, alongside OpenAI’s reported pursuit of a $40 billion funding round at a $260 billion valuation, highlight the intense competition and soaring valuations across the sector. In this environment, Anthropic’s ability to dictate terms, rather than simply accept capital, speaks volumes about its perceived value and strategic importance in shaping the future of artificial intelligence.
