Unacademy takes ChatGPT off PhysicsWallah; the leader still owns Gemini and AI Mode at 78%.
Unacademy takes ChatGPT off PhysicsWallah; the leader still owns Gemini and AI Mode at 78%. After yesterday's clean PhysicsWallah sweep, the Test Prep arc splits engines on day two: Unacademy flips ChatGPT to 72% SoV (rank 2 → 1) on the back of a 20 → 32 cite jump for its own UPSC IAS goal page, while PhysicsWallah holds Gemini and AI Mode at 78% apiece and extends its combined lead to 72% (+4.7 pp). Unacademy itself adds 6.6 pp to reach 65.3% combined — the day's largest mover by brand. Adda247 slips 3.4 pp to rank 4 as Vedantu inches into third on tie-breaker mentions; BYJU'S is stuck at 18.7% with a now 28%/12% ChatGPT-vs-AI-Mode spread, still the widest single-brand gap in the vertical.

Unacademy takes ChatGPT off PhysicsWallah; the leader still owns Gemini and AI Mode at 78%.
The move
After yesterday's clean PhysicsWallah sweep, the Test Prep arc splits engines on day two: Unacademy flips ChatGPT to 72% SoV (rank 2 → 1) on the back of a 20 → 32 cite jump for its own UPSC IAS goal page, while PhysicsWallah holds Gemini and AI Mode at 78% apiece and extends its combined lead to 72% (+4.7 pp).
Unacademy itself adds 6.6 pp to reach 65.3% combined — the day's largest mover by brand.
Adda247 slips 3.4 pp to rank 4 as Vedantu inches into third on tie-breaker mentions; BYJU'S is stuck at 18.7% with a now 28%/12% ChatGPT-vs-AI-Mode spread, still the widest single-brand gap in the vertical.
What it means
The ChatGPT flip is a citation-pool story, not a brand-momentum story: Unacademy is winning ChatGPT because aggregator pages academycheck.comimsindia.comtime4education.comfindmyinstitute.com and its own UPSC product URL all gained cites in parallel, while PhysicsWallah's ChatGPT gains concentrated in UPSC review aggregators visionias.inlegacyias.comdrishtiias.com.
Gemini and AI Mode reward the brand whose own domain (pw.live) and store listings dominate the citation pool; ChatGPT rewards the brand cited by third-party listicles.
For an AEO specialist working a test-prep brand, the lesson is engine-specific: chase domain authority and Play Store presence for Gemini/AI Mode, and chase placement in 'best UPSC/JEE coaching' listicles for ChatGPT.
BYJU'S remains exposed — heavy on cautious sentiment (11%) and absent from the AI Mode citation pool that the leaders own.
