Midjourney bought the astrology app Co-Star
Midjourney, which has gone from generating AI cat images to full-body ultrasound scans, is getting into a new field: astrology. The AI startup announced on Thursday that it has acquired the personalized astrology app Co-Star, as reported earlier by Bloomberg.
Midjourney has acquired Co-Star, the astrology app beloved by millennials who treat their birth chart like a personality test. The financial terms were not disclosed, but the strategic logic is plain enough.
Midjourney built its reputation on image generation, then expanded aggressively into adjacent AI applications. Acquiring Co-Star gives the company a consumer product with a loyal daily-engagement audience, a steady stream of personal data, and a brand that already blends astrology with NASA-sourced astronomical data and AI-driven personalization. That combination is precisely the kind of dataset a generative AI company values: intimate, self-reported, and refreshed every morning.
The move also signals how AI startups are evolving. The frontier is no longer just model performance. It is distribution, habit formation, and proprietary data pipelines. Co-Star delivers all three.
For the labor market, the acquisition is a reminder that AI consolidation is reshaping which companies control the consumer-facing surfaces where personal information is collected. Midjourney now owns a daily touchpoint with millions of users who voluntarily disclose their moods, relationships, and aspirations. That is leverage no model benchmark can replicate.
