10 Major AI Hackathon Events in 2025 Worth Joining

If you’ve ever wanted to put your coding skills, creativity, and problem-solving chops to the test, an AI hackathon might be the perfect playground. These collaborative events bring together developers, students, designers, researchers, and innovators to build AI-powered projects.

Whether you’re looking to experiment with the latest tools, meet like-minded peers, or even launch the next big AI startup idea, hackathons create an energy that’s equal parts challenging and inspiring. This article takes a look at different types of AI hackathons, judging criteria, considerations for team creation, and available events in 2025.

What is an AI hackathon?

An AI hackathon is an event where participants, either individuals or teams, engage in rapid and collaborative engineering, specifically around artificial intelligence or machine learning. These events can be as short as 24 hours or stretch over several months as participants work to solve a specific problem or create an app. These events can be in-person, virtual, or sometimes a hybrid event that combines both formats.

The benefits of these events include hands-on skill development, networking and collaboration, innovation and creativity, portfolio building, industry exposure, and potentially community or industry impact.

AI hackathon categories and types

AI hackathons can be generally categorized by initiative, participants, and format. Some of them can have a technology or software focus, but this can vary between hackathons, depending on sponsoring organizations, available resources, and target audience. The main things to look out for when narrowing down available hackathons include:

• Initiative: A hackathon, or codeathon, can occur for two main reasons: competition and education. In a competitive hackathon, participants create projects and solve problems for prize money or recognition. In educational hackathons, participants spend the day collaborating, coding, and learning about specific technologies.

• Participants: These events can have varied age ranges. Some hackathons are open to attendees as young as 13. However, the majority of hackathons often focus on student participants (middle school, high school, secondary education) and working professionals. Sometimes the hackathon’s prize or location will dictate who can participate due to legal regulations.

• Format: Traditionally, hackathons were on-site events, and would often be condensed into 24-36 hours, but this is changing thanks to the breadth and depth of online events. Now, developers can find hackathons that are in-person, online, or a hybrid format. Online hackathons are usually conducted with collaboration through online communities, Discord servers, or having teams submit projects online. A hybrid format can mean the hackathon has a mix of in-person and online events for attendees over the course of the competition.

Setting up for hackathon success

Whether you’re going solo or assembling a team, preparation is key to making the most of your hackathon experience:

• Technology skills: Learn if the hackathon has specific technology requirements or software that participants must use. If you’re an individual developer, be sure to brush up on any technical skills you think you might use over the course of the hackathon. For teams, make sure to create a diverse team that can tackle all the necessary components of AI design, testing, development, and presentations.

• Team dynamics: For those working with a team, decide on team goals, assign project roles to avoid confusion over workloads, and agree on communication and development tools.

• Project strategy: Start simple when it comes to ideas, as you’ll be confined by either time, development resources, or money. You’re more likely to succeed with a more polished project that can execute its task well or a minimum viable product instead of an overly ambitious project with missing components.

• Networking: A main benefit of hackathons is being able to connect with like-minded individuals and learn from teams or individuals. Be sure to spend time talking with other participants, sharing your learnings, and contributing to projects.

Overall, hackathons are a way to learn, share your skills, or build out your product and showcase it to the broader tech community.
