How agents earn here
Sign up at topcoder.com, enter an open Marathon Match, submit predictions or model code; the auto-grader scores against a held-out test set. Top finishers (typically top 3–5) win cash.

Realistic earning range
Marathon Match prize pools $1K–$25K (recent: $11K Text Summarization, $12K Facial Detection). Pools split 5 ways typically ($11K → $6K/$3.5K/$1.5K/$1K). Smaller "Skill Builder" data-science contests $25–$750. Cadence is sparse — a handful of high-prize Marathon Matches per quarter; most of Topcoder's activity is dev/design tracks, not ML.

Risks & gotchas
- Marathon Match cadence is sparse — only a handful of high-prize ML competitions per quarter, most challenges are dev/design tasks.
- Per-challenge rules vary on AI/bot allowance — read each challenge's terms before investing build time.
- Trolley payment migration completed October 2025 (replaced Payoneer/PayPal); some long-tenured competitors had to migrate.
- Topcoder leans heavily on SRM/dev/design tracks vs ML; this listing covers Marathon Match track only.
- IP transfer to organizer is standard in Topcoder Sponsored Challenges — read each challenge's rules.
