The decentralized prediction markets protocol Rain today announced the launch of its AI agent-ready SDK and a $5 million grant program to support developers and creators worldwide in building, launching, and monetizing their own independent prediction market platforms.
Open Infrastructure for Prediction Markets
Prediction market platforms have dominated public discourse over the past few months, with platforms like Polymarket and Kalshi pursuing valuations approaching $20 billion and presenting themselves as part of a more open financial future. Yet Rain notes that much of the ecosystem remains far more centralized than it appears. Most platforms offer APIs and SDKs that limit interaction to markets the platform itself created, preventing developers from creating new ones independently. Rain is opening the system up to a wider group of builders, allowing both developers and AI agents to access not only existing markets but also the infrastructure needed to create and launch their own applications and markets directly on the protocol.
AI Agent-Ready: From Prompt to Live Market
NVIDIA CEO Jensen Huang recently described OpenClaw as part of a broader shift in AI—from systems that answer questions to ones that can actually perform work. Rain's SDK is built precisely for this shift, exposing the full stack of prediction markets (creation, pricing, trading, liquidity, and resolution) as simple, composable primitives. With Rain, builders using OpenClaw agents can take a single prompt and generate a live prediction market without manual coding or centralized gatekeepers. This allows anyone with an idea to turn it into a functioning market product more quickly than traditional development would allow.
$5 Million Grant Program Details
The grant program allocates $3 million directly to development building on the protocol, while the remaining $2 million funds a daily rewards system designed to incentivize ongoing activity across the ecosystem. Rain is the first protocol in the industry that lets anyone create and launch fully functional prediction markets on any topic, in any language. Builders maintain full control over their product, branding, and regulatory strategy, while using Rain as the underlying technology layer. Every builder earns a flat 0.5% share of the trading volume they generate, paid directly from Rain’s token allocation, creating a predictable revenue stream for those who drive activity on the platform.
Industry Significance and Future Outlook
“In the past year, prediction markets have become one of the most talked about sectors in the market, and Rain is now changing how these platforms are built,” says Roy Shaham, CEO of Rain. “We designed our SDK specifically for OpenClaw and AI agents, allowing anyone to take an initial prompt to a fully live, functional platform. With a $5M pool that is nearly double the industry standard, we give creators the resources to move beyond just pulling data and actually launch their own platforms and create their own markets. By making it easy for anyone to bring their ideas to life with OpenClaw and Rain’s SDK, we are building a colorful ecosystem that pushes the boundaries of what prediction markets can become.”
Rain is a decentralized protocol that provides the infrastructure for anyone to build their own prediction market platforms or applications. The machine-readable Rain SDK supports developers and AI agents, featuring private invitation-only markets, AMM, account abstraction, AI market and dispute resolution, cross-chain support, and more.
