In the first half of 2025, two giants of artificial intelligence have competed not only in capabilities but also in popularity: ChatGPT and Gemini. Thanks to MobSI’s global download tracking (iOS + Android), we can see how this race has evolved from February to August.
February – May: a close race
In the first months, growth was steady and relatively even:
- ChatGPT went from the starting point to +66.4%.
- Gemini did slightly better, reaching +79.2%.
Everything suggested it would be a tight competition.
May – August: Gemini hits full speed
The second part of the period changed the game.
- Gemini went from +79.2% to an impressive +534.4%, adding +455% in just three months.
- ChatGPT, while continuing to grow, went from +66.4% to +148.2%, adding +81.8%.
In summary, Gemini’s growth was nearly six times greater than ChatGPT’s during this stretch.
What’s behind this leap?
Although the chart doesn’t reveal the exact causes, some possible reasons could be:
- New integrations or exclusive features.
- Increased investment in marketing and strategic partnerships.
- Aggressive expansion in emerging markets.
Conclusion: a clear signal to the market
Gemini not only closed the gap but took the lead with explosive growth. For those working in AdTech, marketing, or development, this is a sign that usage trends can shift very quickly, even among the biggest players in the industry.
