Midjourney Buys Astrology App Co-Star in Its First Acquisition

On July 24, 2026, Midjourney announced the purchase of Co-Star, a popular personal astrology app. It is the first acquisition by the AI startup best known for its image generator. The parties have not disclosed the financial terms of the deal, which reportedly closed in spring 2026.

What is Co-Star

Co-Star is a free app that sends users daily horoscopes and lets them check "compatibility" with friends. According to the service's FAQ page, its personalized advice draws on three sources: human expertise, NASA astronomical data, and artificial intelligence.

• Buyer: Midjourney, the developer of the image generator
• Target: the Co-Star app (daily astrology, compatibility tests)
• The deal reportedly closed in spring 2026
• The purchase was announced on July 24, 2026
• The price and terms of the deal have not been disclosed

"Combines human expertise, NASA data, and artificial intelligence," is how the FAQ page of the

Co-Star app itself describes how the service works.

Bloomberg was the first to report the deal, and The Verge confirmed the report. Midjourney founder David Holz publicly commented on the acquisition, speaking positively of Co-Star's founder.

Why would an image generator want astrology

Midjourney has steadily been expanding beyond image generation. The company started with AI pictures of cats, later moved on to generating images such as full-body ultrasound scans, and is now entering consumer services with a ready-made audience. According to Bloomberg, besides buying Co-Star, the startup is developing its own apps in parallel.

The purchase looks like a logical step for a company that has so far grown organically, without acquisitions. A finished product with a loyal user base gives Midjourney a quick way into a new niche, without having to build a consumer app and assemble an audience from scratch.

Why it matters for the market

The deal shows generative AI companies shifting from pure technology to mass-market consumer products. Rather than only improving its generation models, Midjourney is buying a ready-made service and its audience. That is a classic move for mature tech companies, but for a first-generation generative AI startup it is still novel.

Co-Star itself is a hybrid product: it already combines astronomical data and AI. For Midjourney, it is a way to test its technology in an app where generative AI is part of the daily user experience rather than just a picture.

What this means

Midjourney's first-ever acquisition signals that generative AI startups are increasingly buying distribution and audiences instead of only developing their own models. An astrology service with a daily user habit is, for Midjourney, an inexpensive way to move beyond image generation and gain a foothold in the consumer segment.
