AI apps are raking in cash, and ChatGPT is leading the charge. Consumer spending on artificial intelligence tools hit a whopping $1.42 billion this year—a massive 274% spike from 2023. According to app analytics, ChatGPT isn’t just popular; it’s crushing the competition, earning more than all other top AI apps combined.

But who’s using it? Turns out, it’s mostly young guys. Over half of ChatGPT’s mobile users are under 25, suggesting younger folks are quicker to embrace new tech—or maybe they’re just after help with homework. A quarter of U.S. teens admit they’ve used ChatGPT for schoolwork, double the number from last year.

Older users aren’t left out, though. People aged 50 to 64 make up 20% of the app’s audience. But the real standout stat? A staggering 85% of ChatGPT’s mobile users are male.

Why the gender gap? Experts point to women being more cautious about AI. Surveys show women are less likely to let their kids use AI tools and more worried about its risks, like job losses or the rise of harmful deepfake content.

ChatGPT’s dominance isn’t without challengers, though. DeepSeek, a free AI app, has already topped the App Store charts, but it’s got a long way to go to match ChatGPT’s hype.

For now, ChatGPT remains the king of AI apps, but its user base might need to diversify to keep the momentum going.
