The attacker also attempted to use bitcoin linked to the Blink Wallet security breach on September 19, but was unsuccessful. (Bitcoin.com News)
According to BeInCrypto, ARK Invest founder Cathie Wood recently expressed a view that overturns the market's traditional perception of open-source AI. She pointed out that the capabilities of open-source models such as Meta, Mistral, and DeepSeek are continuously enhancing, which instead expands the cybersecurity attack surface, forcing enterprises to continuously procure frontier AI as a defense layer, thereby driving revenue growth for OpenAI and Anthropic rather than harming them. Data from the UK AI Safety Institute shows that the cyber attack capabilities of open-source models have caught up to the level of frontier models from 4 to 7 months ago. Wood named OpenAI, Anthropic, and SpaceXAI as the three companies most likely to capture the bulk of AI model revenue; ARK currently holds positions in all three companies. Currently, Anthropic has already submitted an S-1 filing at a valuation of nearly $1 trillion, and OpenAI is expected to go public in September 2026.
