OpenAI and Anthropic May Be Rivals, but Investors Aren’t Picking Sides

The AI race has long been framed as a zero-sum game, with OpenAI and Anthropic positioned as two of its most formidable contenders. Yet despite their public rivalry and divergent strategies, a surprising number of investors have chosen to back both, creating a paradox that reflects the growing uncertainty in the sector.

The Unusual Investor Overlap

According to a WIRED analysis of PitchBook data, over 90 venture capital firms have stakes in both OpenAI and Anthropic, with 42 percent of OpenAI’s investors also present in Anthropic’s funding circle. This overlap includes major names like Sequoia Capital, Greylock, and Founders Fund, which have backed both companies despite their competition. Such alignment is rare in venture capital, where firms typically avoid backing direct rivals to prevent conflicts of interest.

Investors are betting on both OpenAI and Anthropic to hedge their exposure to the AI sector. Overlapping stakes suggest investors are unsure which company will dominate the market. This trend has only grown more pronounced as both companies raise unprecedented sums.

A Shift in Venture Capital Strategy

The rise of OpenAI and Anthropic has forced venture capital firms to rethink traditional strategies. With valuations approaching $1 trillion and fundraising rounds exceeding $100 billion, the sheer scale of these companies has blurred the lines between venture capital, private equity, and hedge funds. Larger funds now spread their bets across multiple startups, reducing the influence any one investor can exert.

This shift is also driven by the length of time companies stay private. In the past, firms could take a position in one company and watch it grow into a public entity. Now, with OpenAI and Anthropic showing no signs of going public anytime soon, investors are diversifying to ensure they’re not left behind.

The IPO Race and Investor Hedges

Anthropic and OpenAI are both expected to go public in 2025, a move that could provide early returns for their investors. With IPOs historically offering mixed results—only two-thirds of recent ones saw significant gains—some firms are choosing to back both to increase their chances of success.

For investors, the stakes are high. The AI sector is still in its infancy, and the eventual winner could reshape industries. By backing both OpenAI and Anthropic, investors are not just hedging their bets—they are positioning themselves to benefit regardless of which company emerges as the dominant force.

As the race for AI dominance continues, the role of investors is evolving. Their willingness to back both OpenAI and Anthropic suggests a market where uncertainty is the norm, and the path to success is far from clear. This dynamic will likely shape the future of the industry, as capital flows and strategic alliances continue to form in an arena where the rules are still being written.
