The rivalry between OpenAI and Anthropic has escalated into a public feud over Pentagon contracts, revealing deep philosophical divides about AI development. Sam Altman's OpenAI signed a defense deal after Anthropic walked away from negotiations, triggering protests and a social media backlash against Altman.

Anthropic's refusal to compromise on ethical safeguards for military applications has boosted its public image and app downloads. The company's revenue projections doubled to $19 billion this year, up from $9 billion in 2024, as it adds thousands of enterprise customers. Dario Amodei's departure from OpenAI in 2021 to found Anthropic stemmed from disagreements over commercialization speed and safety protocols.

This battle extends beyond technology to competing visions of AI's role in society. Anthropic's stance on preventing autonomous weapons and surveillance contrasts sharply with OpenAI's more aggressive Pentagon partnership. The conflict has become deeply personal between the two CEOs, who awkwardly avoided hand-holding at a recent tech summit with India's prime minister. With Anthropic aiming to IPO before OpenAI, the race for AI dominance has never been more intense.
