The Solana Fall 2026 Hackathon is the highly anticipated second global online startup competition of the year, hosted by Colosseum. Over the course of 5 weeks, builders from around the world will form teams to develop innovative products natively on the Solana blockchain. Top projects will compete for ecosystem recognition, substantial prize tracks, and the opportunity to be accepted into the Colosseum accelerator program, which historically provides $250,000 in pre-seed funding to select winners. For founders seeking continuous development, the newly enriched Eternal sprint feature also offers an ongoing on-chain competition outside of the fixed hackathon windows.
To participate in the Solana Fall 2026 Hackathon, developers and startup founders must register via the official Colosseum platform. During the 5-week active window from September 28 to November 2, 2026, teams are required to build a functional MVP on the Solana blockchain, complete with a GitHub repository, a clear monetization strategy, and full team credentials.
While the exact prize breakdown for the Fall edition is yet to be announced, it is expected to mirror the recent Frontier spring edition, which featured a massive $2.75 million total prize and investment pool. Top-performing teams will be evaluated by ecosystem leaders and may advance to interviews for the Colosseum accelerator program, which awards $250,000 in pre-seed funding to select winning teams. Additionally, founders who wish to build outside these fixed windows can utilize the confirmed Eternal sprint feature for continuous, on-chain project submission.
