Cybersecurity stocks' large run-up is at risk from a cheaper, open Chinese AI model. ValsAI reports that DeepSeek V4.1 Flash 1017 beat GPT 6 Sol on its offensive cybersecurity task; DeepSeek is far cheaper to run than a closed US model. x.com 

Palo Alto Networks is better placed than AI model labs to sell autonomous security, because customers need an accountable party when an automated action is wrong. At L4 or L5 autonomy, systems quarantine machines, kill processes, revoke access or block traffic with no human in the loop.

Model labs' terms usually limit what they answer for, leaving outside agents L2 work. … Show more

Palantir's reliance on pay-as-you-go service with refunds makes customer cancellations and sudden earnings declines or write-downs a serious risk as AI and high SaaS prices pressure the business. Its 10-Q warns of these risks. Anthropic can and will easily replace Palantir with an all-in-one platform under Democratic control of the legislative branches. x.com  x.com

Cybersecurity stocks such as CrowdStrike and Palo Alto Networks are set to de-rate in 2027 as Anthropic and OpenAI aggressively productize frontier models into cybersecurity. The whole cyber industry would face competitive risk and lose budget share. Frontier models have a tangible edge over apps in cyber, and the labs need such revenue to justify their valuations. Palo Alto's Nikesh Arora and CrowdStrike's George Kurtz may talk big now; their demeanor 12-18 months from now is the test. x.com  … Show more
