AI Shift: OpenAI VCs Now Bet on Anthropic—Is Loyalty Dead?

The artificial intelligence landscape is undergoing a seismic shift. With OpenAI poised to finalize a staggering $100 billion funding round, and Anthropic recently securing a massive $30 billion raise, a fundamental principle of venture capital – investor loyalty – is being severely tested. The lines are blurring, and the traditional boundaries between competing investments are crumbling. This isn't just about money; it's about a potential reshaping of how venture capital operates in the age of AI.

The Rise of Dual Investments: A Breach of Tradition?

What’s particularly striking is the number of investors backing both OpenAI and Anthropic. At least a dozen direct investors in OpenAI have also participated in Anthropic’s $30 billion funding round. These include prominent firms like Founders Fund, Iconiq, Insight Partners, and Sequoia Capital. This trend signals a departure from the long-held belief that VCs should champion their portfolio companies, especially against direct competitors.

The Hedge Fund Factor

Some dual investments are more understandable when originating from hedge funds or asset managers. Their focus often extends to public stocks, including those of competitors. Firms like D1, Fidelity, and TPG fall into this category. Their investment strategies prioritize broader market exposure and potential returns, regardless of direct competition within their portfolio.

BlackRock's Complicated Position

However, one investment raised eyebrows: Affiliated funds of BlackRock joined Anthropic’s raise despite Adebayo Ogunlesi, BlackRock’s senior managing director and board member, also sitting on OpenAI’s board. While BlackRock manages diverse funds and may seize opportunities to invest in OpenAI regardless of Ogunlesi’s affiliation, the situation highlights the potential for conflicts of interest. The sheer scale of the AI market and potential returns likely outweigh these concerns for large, diversified firms.

Microsoft, Nvidia, and the Hedging of Bets

The strategic investments of tech giants like Microsoft and Nvidia further complicate the picture. Microsoft’s deep partnership with OpenAI doesn’t preclude it from exploring opportunities with other AI labs. Similarly, Nvidia, a crucial supplier of AI hardware, benefits from the growth of the entire ecosystem, making investments in multiple players a logical move. These companies aren’t bound by the same “founder-friendly” ethos as traditional VCs.

The VC Dilemma: Loyalty vs. Opportunity

Traditionally, venture capital firms have marketed themselves as “founder-friendly” and “helpful.” The expectation was that a VC’s investment came with a commitment to supporting the startup’s success, particularly against its rivals. But when an investor holds stakes in both OpenAI and Anthropic, where does their loyalty truly lie? The answer, increasingly, seems to be with their own investors and maximizing returns.

Confidentiality Concerns and Fiduciary Duty

Startups, being private entities, share confidential business information with their direct investors – data not publicly available to competitors. VCs often secure board seats, carrying a fiduciary responsibility to their portfolio companies. This raises serious questions about information flow and potential conflicts when an investor is simultaneously involved with competing firms. Can confidential information truly remain secure when shared with investors who have a vested interest in the competition?

Sam Altman's Stance and the Shifting Landscape

The situation is made even more intriguing by Sam Altman’s background. As a former president of Y Combinator, he understands the VC landscape intimately. In 2024, reports surfaced that Altman provided his investors with a list of OpenAI rivals he discouraged them from backing, including Anthropic, xAI, and Safe Superintelligence.

Altman later clarified that he didn’t prohibit investments in rivals, but warned that “non-passive investments” would result in a loss of access to OpenAI’s confidential business information, as revealed in documents related to the Elon Musk vs. OpenAI lawsuit (Business Insider). This demonstrates a clear attempt to protect OpenAI’s competitive advantage, but ultimately, the allure of potential returns proved too strong for many investors.

The Power of Record-Breaking Funding Rounds

The unprecedented amounts of capital flowing into AI labs are a key driver of this shift. The sheer scale of funding needed to build and operate these complex systems, coupled with the potential for massive returns, creates a situation where saying “no” becomes increasingly difficult. The AI gold rush is in full swing, and investors are eager to secure a piece of the action, even if it means blurring traditional lines.

Not All VCs Are Jumping Ship

Despite the trend, not all venture investors have abandoned their traditional approach. Andreessen Horowitz backs OpenAI but has not (yet) invested in Anthropic. Menlo Ventures supports Anthropic but remains on the sidelines for OpenAI. A dozen other investors, in our research, appear to maintain exclusive investments in either OpenAI or Anthropic, demonstrating that some firms still prioritize loyalty and avoid direct conflicts of interest.

These include Bessemer Venture Partners, General Catalyst, and Greenoaks. (It’s worth noting that relying on AI tools like Claude for this research proved unreliable, highlighting the need for human verification even with advanced technology.)

The New Reality: Conflict-of-Interest Policies and Founder Due Diligence

The actions of respected firms like Sequoia Capital signal a significant change in the venture capital landscape. One investor, speaking anonymously, suggested that as long as the firm doesn’t hold a board seat, the perceived harm is diminishing. However, this perspective doesn’t address the underlying concerns about information sharing and potential conflicts of interest.

Founders must now prioritize thorough due diligence on potential investors, specifically inquiring about conflict-of-interest policies before signing any term sheet. This includes understanding the investor’s existing portfolio and their willingness to support the startup against its competitors. The era of unquestioning trust in VC loyalty is over.

The Future of AI Investment: A More Complex Landscape

The AI revolution is forcing a re-evaluation of traditional venture capital norms. The massive funding rounds, the competitive intensity, and the potential for outsized returns are creating a new reality where investor loyalty is increasingly secondary to financial opportunity. This shift has significant implications for startups, investors, and the future of the AI industry. The question now is whether this trend will continue, and what safeguards can be put in place to protect the interests of founders and ensure a fair and competitive AI ecosystem.

Key Takeaways:

• Investor loyalty in the AI space is eroding as VCs increasingly back competing companies.
• The massive funding rounds and potential returns are driving this shift.
• Founders must prioritize due diligence and conflict-of-interest policies.
• The AI landscape is becoming more complex and competitive.

The AI arms race is on, and the rules of engagement are still being written. Staying informed and adapting to this evolving landscape will be crucial for success in the years to come.
