Open-Source AI Creates Boom for Frontier Labs

Cathie Wood of ARK Invest argues that open-source AI is not bad news for frontier labs like OpenAI and Anthropic. According to her, an open-weight AI model allows anyone to download, run, and modify it on their own hardware without paying for access.

Wood claims that the real threat of open-weight models is not that they replace frontier AI, but rather that bad actors use them to attack enterprises. This security pressure forces companies to keep buying frontier-grade AI for protection, making OpenAI and Anthropic richer, not poorer.

The UK's AI Security Institute found that open-weight models now match frontier cyber capabilities from just four to seven months ago. ARK's own AI primetime report flagged expanding AI infrastructure spend as a defining trend of the decade.

Wood believes that OpenAI, Anthropic, and SpaceXAI are likely to take the majority of model-driven revenue. She notes that the cheaper AI gets for attackers, the more enterprises need the best defense available.
