ChatGPT Isn't the Only AI Worth Using to Make Money in 2026
For the first time since its launch, ChatGPT's market share has dropped below 50%. As of May 2026, it holds 46.4% of the AI assistant market, with Google's Gemini at 27.7% and Anthropic's Claude at 10.3%, according to Sensor Tower's State of AI Report. A year ago, ChatGPT commanded the large majority of this market on its own.
That shift matters for more than just tech headlines. Almost every “make money with AI” guide published in the last two years — including plenty of good ones — assumes ChatGPT by default. The prompts, the platform recommendations, the entire vocabulary of AI side hustle content was built around one tool. That assumption no longer matches where users, or the income opportunities, actually are.
If you're looking to start or grow an AI-related side income in 2026, this shift creates a genuine opening: the methods built specifically around Gemini and Claude are far less saturated than their ChatGPT equivalents, simply because most content creators haven't caught up to the platform shift yet.
Why This Shift Happened
A few concrete events drove the change, and understanding them helps explain where the opportunity actually sits.
Gemini's growth is largely structural. Google has embedded Gemini directly into Android, Google Search, and Workspace, giving it a distribution advantage ChatGPT has to work much harder to match. Users encounter Gemini by default inside tools they already use daily, rather than needing to seek out a separate app.
Claude's growth has a different driver. Claude went from roughly 60 million monthly users in December 2025 to 245 million by May 2026 — a four-fold increase in six months that significantly outpaced every other major model. Part of this followed OpenAI's defense department contract announced in February 2026, which triggered a documented spike in ChatGPT uninstalls among users who objected to their AI provider holding classified military contracts. Claude has also built a strong reputation specifically for productivity use cases, and it leads the field on a telling metric: 13% of Anthropic's users pay for a subscription, the highest conversion rate of any major assistant.
The practical result: roughly one in five AI users now uses multiple AI apps regularly, rather than defaulting to a single tool. The market isn't just fragmenting — people are actively choosing different tools for different tasks.
Where the Real Opportunity Sits
This isn't about abandoning ChatGPT — it remains the largest platform by a wide margin, and it's still a legitimate tool for AI-assisted income. The opportunity is in recognizing that an entire layer of beginner-friendly income methods hasn't been rebuilt around the platforms gaining the fastest ground.
Selling Claude- and Gemini-Specific Prompts
Prompt marketplaces like PromptBase support ChatGPT, Midjourney, Claude, and Gemini alike, but the overwhelming majority of existing prompt listings were written for ChatGPT, simply because it was the default for so long. As Claude and Gemini usage scales into the hundreds of millions of monthly users, the demand for prompts built specifically around their strengths is growing faster than the supply of sellers serving it.
Claude in particular has built a reputation around longer, more structured tasks — document analysis, coding, and multi-step reasoning. A prompt pack built specifically for Claude's strengths in one of those areas faces meaningfully less competition than a generic ChatGPT writing prompt pack, where thousands of near-identical listings already exist.
Freelance Services Built Around Multi-Model Workflows
Businesses are increasingly aware that different models have different strengths, but most don't have the time to figure out which tool fits which task. A freelancer who can confidently say “I use Claude for document-heavy analysis, Gemini for anything tied into Google Workspace, and ChatGPT for general drafting” is offering something more sophisticated than someone who only knows one tool — and that combination is still rare enough to be a genuine differentiator on freelance platforms.
Tutorials and Guides for the Newly Switching
Every time a large number of users moves between platforms — and the data shows real movement happening right now — there's a corresponding wave of people searching “how to do X in Gemini” or “Claude vs ChatGPT for Y,” often because they're switching for the first time and don't yet know the new platform's habits. Content and tutorial creators who address this specific transition moment, rather than writing generically about “AI tools,” are positioned ahead of a search demand curve that's still rising.
A Realistic Comparison: Where Each Platform Actually Fits
Platform | Market Share (May 2026) | Strongest Fit For | Side Hustle Angle |
ChatGPT | 46.4% | General writing, broad familiarity, largest existing user base | Still the largest audience for content and prompt sales, but the most saturated competition |
Gemini | 27.7% | Workspace-integrated tasks, multimodal input, fastest-growing user base | Newer prompt categories, automation tied to Google ecosystem tools |
Claude | 10.3% | Long-document analysis, coding, structured reasoning, highest paid-subscriber rate | Less saturated prompt categories, freelance positioning around technical/analytical work |
The smallest market share in this table is, somewhat counterintuitively, often the easiest place to find an underserved niche — fewer total users means fewer existing sellers and content creators have already claimed the obvious opportunities.
A Practical First Step
If you're already doing any kind of AI-assisted side income — selling prompts, freelancing, building simple automations — the lowest-effort next step is straightforward: take one service or product you already offer for ChatGPT, and rebuild a version of it specifically for Claude or Gemini. Test it, document how the output differs, and list it alongside your existing offering rather than replacing it.
This isn't about picking a side in a platform rivalry. It's about recognizing that a meaningful share of your potential audience has already moved, and most of the content and product landscape hasn't moved with them yet.
FAQs
Does this mean ChatGPT is becoming irrelevant for making money with AI?
No. ChatGPT still holds the largest single share of the market at 46.4% and remains a legitimate platform for AI-assisted income. The opportunity discussed here is about reduced competition in Gemini- and Claude-specific niches, not about ChatGPT losing relevance.
Is it worth learning Claude or Gemini if I'm already comfortable with ChatGPT?
For income purposes, yes, at least at a basic level. The data shows real user migration happening, and being the freelancer or seller who can competently work across multiple platforms is a genuine point of differentiation right now, while that's still relatively uncommon.
Why is Claude growing so fast despite having the smallest market share?
Claude's growth — roughly four times its user base in six months — followed a combination of factors: a documented wave of ChatGPT uninstalls after OpenAI's defense department deal, and a strong reputation specifically for productivity and technical use cases. It also leads the industry in paid subscription conversion at 13% of users, suggesting strong user satisfaction among its base.
Where can I find current, accurate platform usage data instead of guessing?
Sensor Tower's State of AI Report and Similarweb's AI tracker are both cited regularly in mainstream tech coverage and are reasonable starting points for checking current market share figures, since this data shifts meaningfully every few months.
Conclusion
A market shift this size — ChatGPT dropping below 50% share for the first time, Claude quadrupling its user base in six months — doesn't happen quietly, and it doesn't happen without creating real openings for anyone paying attention. The AI side hustle content landscape is still almost entirely built around a single platform that no longer represents even half the market. Rebuilding even one existing prompt, service, or piece of content specifically for Gemini or Claude is a small, concrete way to move into space that's measurably less crowded than where everyone else is still competing.
