Fragmented Prediction Market APIs

Developers building prediction market applications must integrate separately with multiple platforms (Kalshi, Polymarket, others), duplicating effort across different API standards, authentication schemes, and data formats.

A unified API abstraction layer that consolidates fragmented prediction market platforms into a single developer interface.

The pain

Developers building prediction market apps face significant friction: multiple API integrations, inconsistent authentication, different data schemas, and maintenance burden across platforms. Each new platform integration multiplies complexity.

The gap

No standardized abstraction layer exists. Developers either accept fragmentation costs or build custom wrappers, both suboptimal. The market is too young for de facto standards to have emerged.

Build angle

Start as a lightweight SDK/wrapper (not a platform). Target the highest-friction integrations first (Kalshi + Polymarket). Charge per API call or tiered subscription. Expand to emerging platforms as they launch.

Strengths

  • Clear, quantifiable pain point with real developer friction
  • Low barrier to initial MVP (wrapper layer, not infrastructure)
  • Prediction markets are growing rapidly (regulatory tailwinds, institutional interest)
  • High switching costs once integrated, good retention
  • Potential to become essential infrastructure as market matures
  • YC-validated problem space with multiple funded competitors

Risks

  • Platforms may build their own unified APIs, eliminating the need
  • Small TAM initially, only ~100-500 active prediction market developers today
  • API terms of service may prohibit abstraction layers or require revenue sharing
  • Regulatory uncertainty around prediction markets could stall growth
  • Low willingness to pay from early-stage startups (your primary customers)
  • Network effects favor the largest platform, consolidation risk
  • Requires constant maintenance as platforms evolve their APIs
