State of Hackathons 2025

Hackathons went online

Lockdowns shut every venue and the format flipped overnight. Organisers wired up Discord, Devpost and Zoom rooms in a weekend and the whole calendar moved into the browser. Suddenly a hackathon in Lagos could share judges with one in Toronto, and weekend attendance ceilings stopped existing.

Online became the default format

Builders found their format

Online stayed dominant, prize pools ballooned and every Layer 2 wanted its own weekend. ETHGlobal, Solana and Polygon ran near-continuous circuits, with six-figure pools handed out for protocol integrations. Sponsorship money, most of it crypto-native, set expectations that distorted the rest of the ecosystem for a year.

Crypto money receded

Token prices cratered, sponsorship budgets evaporated and the prize-pool arms race ended. The events that survived leaned back into community: smaller weekends, tighter themes, sharper judging. Less noise, more signal, and the first hints that something else was about to take over the brief.

Speculative sponsors stepped back

ChatGPT changed the brief

Within months of GPT-3.5 going public, hackathon themes pivoted hard. OpenAI, Anthropic and a wave of foundation-model startups started sponsoring tracks directly, and "build something with an LLM" went from novelty to default. Veterans grumbled about prompt-engineering wrappers; everyone shipped them anyway.

Hybrid became the default

Travel was back and enterprise sponsors wanted bodies in rooms again. University campuses, AWS lofts and corporate HQs filled up for multi-day in-person tracks, but no one dropped the online stream. Hybrid stuck. The audience that found hackathons during lockdown wasn't going to be cut off just because flights were running again.

Hybrid replaced online-only as the norm

AI ate the calendar

Roughly half of every event we track now namechecks AI, ML or agents. Devtool companies like Vercel, Supabase, LangChain and MCP-aligned startups poured sponsorship in to reach the builder audience directly. Multi-track "AI agent" events became their own category, and prize pools followed.
