On May 19, 2026, at Google I/O, Google announced Build with Gemini XPRIZE—a $2 million global competition challenging builders to create real businesses in 90 days using Gemini's agentic AI stack (Gemini App, AI Studio, Antigravity, Stitch, Flow). Unlike traditional hackathons that reward prototypes, this prize requires real users, real revenue, and AI in production. Projects compete across five categories—Education, Entrepreneurship, Small Business Services, Financial Access, Professional Services—with the top 5 pitching live at the Moonshot Summit in Los Angeles on September 25, 2026 for a share of $1.75M in grand prizes. Registrants get $100 in Google AI Ultra credits and $300 in Cloud credits, and the competition explicitly encourages solving everyday problems, not moonshots.
This article covers how the prize works, the five categories, the full Gemini toolstack, judging criteria, and how to register.

The Moonshot: 90 days to build a real business
From the official site:
"90 days. Ideate. Build. Ship. Grow. Real product. Real revenue. A real business."
The four phases:
| Phase | What it means | Tools |
|---|---|---|
| 01 · Ideate | Pick a real problem worth solving. AI helps you scope it. | Gemini App (brainstorming, market validation) |
| 02 · Build | Build a working prototype using AI. | AI Studio (rapid prototyping), Antigravity (agent teams) |
| 03 · Ship | Deploy the business. Real users in production. | Google Cloud (hosting), Stitch (UI design) |
| 04 · Grow | Market it. Grow it. Show the revenue. | Flow (marketing videos), Pomelli (content generation) |
Why "real business" matters: Unlike traditional hackathons that reward demos, this prize requires:
- Real users (not test accounts)
- Real revenue (paying customers or monetization strategy)
- Sustainable model (not one-time viral spike)
Why 90 days? Proven duration for MVP → first revenue. Enough time to validate, build, launch, iterate—but tight enough to force focus.
The Five Categories: Real Problems, Real Communities
Each category targets everyday problems people face:
01 · Education & Human Potential
Transforming how we learn, grow, and achieve our best.
Example problems:
- Personalized tutoring for underserved students
- Career skills training for job seekers
- Language learning for immigrants
- Exam prep for certifications
Why AI helps: Personalized curriculum, instant feedback, adaptive difficulty, 24/7 availability.
02 · Entrepreneurship & Job Creation
Fueling the tools that help new founders and economies thrive.
Example problems:
- Business plan generators for first-time founders
- Legal/accounting automation for solopreneurs
- Gig economy tools for freelancers
- AI co-founders for technical non-founders
Why AI helps: Removes barriers to starting—legal docs, financial models, pitch decks, MVP builders.
03 · Small Business Services
Powering everyday businesses with tools to compete and win.
Example problems:
- Inventory management for local retailers
- Scheduling automation for service businesses
- Customer support for mom-and-pop shops
- Marketing automation for restaurants
Why AI helps: Small businesses can't afford full-time staff for these functions—AI levels the playing field.
04 · Money & Financial Access
Breaking down barriers to banking, capital, and financial freedom.
Example problems:
- Micro-lending for underbanked communities
- Financial literacy tools for low-income families
- Invoice factoring for small contractors
- Credit-building platforms for immigrants
Why AI helps: Automates underwriting, risk assessment, personalized financial advice—at scale.
05 · Professional Services Access
Connecting everyday people with the expert guidance they need.
Example problems:
- Legal advice chatbots for tenant rights
- Tax prep for gig workers
- Healthcare navigation for uninsured
- Career counseling for career-switchers
Why AI helps: Professional services are expensive—AI makes expertise accessible to everyone.

Judging Criteria: Three Dimensions
Projects are judged on:
1. Business Viability
Real business, real users, real revenue—and a model that sustains.
What judges look for:
- Revenue: Paying customers or clear monetization path
- Users: Actual humans using the product (not test accounts)
- Unit economics: Path to profitability, not just growth
- Retention: Users coming back, not one-time viral spike
Why this matters: Separates real businesses from clever demos.
2. AI-Native Operations
AI live in production, executing key business decisions across the operation.
What judges look for:
- AI in the loop: Not just UI cosmetics—AI making decisions
- Production-grade: Real customers interacting with AI, not demos
- Business-critical: AI handles core workflows (customer support, content generation, pricing, etc.)
Why this matters: This isn't a "build anything" contest—it's specifically about AI-powered businesses.
3. Category Impact
Meaningfully moves the needle in your chosen category.
What judges look for:
- Problem clarity: Solving a real pain point, not a nice-to-have
- Community fit: Built for the people actually affected
- Scale potential: Can reach thousands, not just a few friends
Why this matters: XPRIZE's mission is impact, not just innovation.

Community Reactions
"What does building real positive change actually look like when the tools are this powerful? This feels like a real test."
"$2M sounds great, but who defines 'for the better'?"
"Prize programs attract the wrong builders unless eligibility criteria are sharp. The good ones filter for serious teams upfront instead of trying to select retroactively after a flood of submissions."
"Time to dust my keyboard and build"
