Highlights
- Sui Overflow 2026 drew 747 project submissions from builders in 58 countries over its six-week run.
- 26 teams won across four core tracks: Agentic Web, DeFi & Payments, Walrus, and DeepBook.
- A separate university-focused prize pool recognized 10 additional student teams.
- Submissions grew roughly 25% over Sui Overflow 2025's 599 total entries.
Sui Network has named the winners of Sui Overflow 2026, its annual global hackathon, after a six-week competition that drew 747 project submissions from developers in 58 countries, PANews reported. Twenty-six teams were selected as winners across four headline tracks — Agentic Web, DeFi & Payments, Walrus, and DeepBook — with an additional 10 teams recognized through a dedicated university prize category aimed at rewarding student-built projects.
A Growing Developer Funnel
The submission count marks a clear step up from the previous edition: Sui Overflow 2025 concluded with 599 total project submissions and 36 winning teams selected across nine tracks, including its own university group category. That itself was a jump from the inaugural Sui Overflow 2024, which drew 352 submissions and 32 winners over an April-to-June run — meaning the event has more than doubled its submission count in two years. This year's narrower four-track structure — with $500,000-plus in total prizes across core and sponsored categories — appears to have concentrated submissions into fewer, more competitive lanes rather than spreading them thin, even as the raw entry count grew by roughly a quarter year over year. For a layer-1 network competing for developer mindshare against Solana, Aptos, and a crowded field of newer chains, a rising hackathon submission count is one of the more concrete signals of ecosystem momentum available, since it reflects actual working prototypes rather than announced funding or TVL that can be inflated by incentive programs.
Where the Building Is Happening
The track lineup itself is a signal of where Sui's core team wants developer attention focused. Agentic Web points at AI-agent tooling built on-chain, an area every major smart-contract platform is racing to stake a claim in as autonomous agents increasingly need verifiable, on-chain rails for payments and identity. DeFi & Payments remains the perennial anchor category for any L1 hackathon, while the inclusion of Walrus — Sui's decentralized storage network — and DeepBook — its native on-chain order book — as standalone tracks reflects the ecosystem's push to get third-party developers building directly on top of its own infrastructure primitives rather than only on generic smart-contract tooling.

What Happens to the Winners Next
The real test for any hackathon is what survives past the prize ceremony: historically, only a fraction of hackathon-winning projects go on to raise funding or ship a production mainnet product. Watch for whether Sui's ecosystem fund or venture partners follow up with grants or investment for the strongest Agentic Web and DeFi & Payments winners in the coming months, and whether next year's Sui Overflow 2027 either expands back toward a broader track structure or continues narrowing focus — a decision that will say a lot about which parts of the Sui stack its foundation sees as strategically most important to seed with outside developer talent.
