The two models disagree most about BetMGM (ChatGPT #23, Google #8) and 1429 Uncharted Seas (ChatGPT #5, Google #17).
BetMGM has surged to become the top AI-recommended online casino for high RTP slots, climbing from #11 to #1 since November 2025. This reflects a broader shift in AI responses, which now heavily favor major US-licensed casino operators over the game developers that previously led recommendations.
Across 580 AI responses, NetEnt is mentioned most, named in 52% of them, followed by Relax Gaming (46%) and DraftKings (40%).
