The AI Investment Paradox: Loyalty Crumbles as VCs Back Competing Giants

The landscape of venture capital and institutional investment is undergoing a seismic shift, particularly within the burgeoning artificial intelligence sector, where traditional notions of investor "loyalty" are rapidly eroding. With OpenAI reportedly on the cusp of finalizing an staggering $100 billion funding round and Anthropic having just concluded its own colossal $30 billion Series G raise, valuing it at $380 billion, a new norm appears to be taking hold: investors are increasingly backing direct competitors. This unprecedented trend challenges long-held principles, especially within the venture capital community.

An examination of Anthropic’s recent $30 billion raise reveals a striking pattern: at least a dozen direct investors in OpenAI were also announced as backers in Anthropic. This list includes prominent firms such as Founders Fund, Iconiq, Insight Partners, and Sequoia Capital. This dual investment strategy, once considered taboo in venture capital, signifies a profound re-evaluation of risk, reward, and competitive positioning in the high-stakes AI race.

For certain types of investors, such dual commitments are perhaps more readily understood. Large hedge funds and asset managers, whose primary focus often lies in public market equities, frequently invest across an entire sector, regardless of competitive dynamics. Their portfolios are designed to capture broad market trends, and owning shares in multiple industry leaders, even rivals, is a standard practice. Firms like D1, Fidelity, and TPG fall into this category, where their investment rationale is typically driven by diversified exposure and the pursuit of returns across a wide array of public and private assets.

However, the participation of certain entities in Anthropic’s raise, despite existing ties to OpenAI, has raised eyebrows. Affiliated funds of BlackRock, the world’s largest asset manager, notably joined Anthropic’s $30 billion round. This move is particularly remarkable given that Adebayo Ogunlesi, a senior managing director and board member at BlackRock, also serves on OpenAI’s board of directors. While BlackRock operates a vast array of funds—including mutual funds, closed-end funds, and exchange-traded funds—each with its own investment mandate, and would likely seize any opportunity to invest in a promising entity like OpenAI, the direct personal association of a senior leader with a primary competitor underscores the evolving complexity of investor relationships. It also echoes the hedging strategies seen with major tech players like Microsoft and Nvidia, both of whom have significant stakes and partnerships across various AI foundational model developers, acknowledging the need to diversify their bets in a rapidly evolving market.

Historically, venture capital funds have operated under a distinctly different ethos. VCs traditionally position themselves as "founder friendly" and "helpful" partners, offering not just capital but also strategic guidance, network access, and active support to their portfolio companies. The implicit understanding has always been that when a VC firm invests in a startup, it commits to helping that startup succeed, especially in its competition against major rivals. This model fosters a sense of allegiance, where a VC’s loyalty is expected to reside squarely with its portfolio company. The question then arises: if a firm is an owner in both OpenAI and Anthropic, to whom does its loyalty genuinely belong, beyond its own limited partners?

This issue is further complicated by the inherent nature of private company investments. Startups, unlike publicly traded corporations, typically share highly confidential information with their direct investors regarding their business status, strategic roadmaps, financial performance, and competitive intelligence. This data is not publicly disclosed. Moreover, VCs often take board seats in their portfolio companies, assuming a fiduciary responsibility to those companies. Holding a board seat or having deep insight into two direct competitors creates a clear potential for conflict of interest, as proprietary information from one company could inadvertently or intentionally influence decisions related to the other.

The prominence of Sam Altman, OpenAI’s CEO, in the venture capital world adds another layer of intrigue to this situation. As a former president of Y Combinator, Altman is intimately familiar with the dynamics and unwritten rules of venture investing. In 2024, reports indicated that Altman had provided his investors with a list of OpenAI’s key rivals—companies like Anthropic, xAI, and Safe Superintelligence (launched by former OpenAI chief scientist Ilya Sutskever)—and expressed a preference for investors not to back them. While Altman later denied explicitly "barring" investors from future OpenAI rounds if they backed these rivals, he did acknowledge stating that investors making "non-passive investments" in competitors would no longer receive OpenAI’s confidential business information. This clarification, revealed in documents pertaining to the lawsuit between Elon Musk and OpenAI, as reported by Business Insider, highlights the sensitivity surrounding competitive intelligence and investor conduct.

The unique characteristics of the AI sector itself are a significant driver of this shift in investor behavior. The leading AI laboratories are raising unprecedented amounts of capital, fueled by never-before-seen rates of growth and immense infrastructure demands, particularly for data centers and specialized hardware like GPUs. The sheer scale of investment required, coupled with the potential for exponential returns, makes it exceedingly difficult for any investor to decline participation when a funding round for an AI giant opens. The "fear of missing out" (FOMO) on potentially transformative technologies and market leadership is a powerful motivator.

Despite the growing trend of dual investments, not all venture investors have yet succumbed to what some might see as a "slippery slope." Firms like Andreessen Horowitz continue to back OpenAI exclusively (at least publicly), while Menlo Ventures has invested solely in Anthropic. In admittedly non-exhaustive research, approximately a dozen investors were identified who appear to maintain direct investments in only one of these two leading AI entities. This group includes Bessemer Venture Partners, General Catalyst, and Greenoaks, suggesting that the traditional VC model still holds sway for some. (It’s worth noting, as a side observation on AI tools, that an initial attempt to compile a list of dual investors using Claude AI yielded almost as many incorrect entries as correct ones, underscoring the need for human verification even with advanced technologies.)

Nevertheless, the fact that a longstanding venture capital "rule" has been set aside by some of the most respected firms in Silicon Valley, such as Sequoia, is highly notable. One investor, when queried about the practice, reportedly shrugged off concerns, stating that as long as the firm does not hold a board seat in both competing companies, they perceive no harm in the dual investment strategy.

This evolving landscape necessitates a re-evaluation of existing practices. For founders, the era of unquestioning investor loyalty may be drawing to a close. Before signing a term sheet, founders should now explicitly inquire about potential investors’ conflict-of-interest policies and their investment strategies across the competitive landscape. This shift, perhaps discussed at upcoming industry events like the TechCrunch event in Boston, MA on June 9, 2026, signals a maturation and a fundamental reordering of relationships within the venture ecosystem, driven by the unprecedented opportunities and demands of the artificial intelligence revolution.
