Rain, the decentralized prediction markets protocol, has announced the launch of an AI agent-ready Software Development Kit (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 to builders and creators globally, the initiative aims to accelerate the growth of decentralized prediction markets by providing the funding and infrastructure needed to launch new platforms on top of the Rain protocol.
The Centralization Problem in Prediction Markets
Prediction market platforms have dominated public discourse over the past few months, quickly gaining unprecedented popularity. Yet even as platforms like Polymarket and Kalshi pursue valuations approaching $20 billion and position themselves as part of a more open financial future, 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, allowing developers to build discovery, analytics, or trading tools around these markets but not to create new ones independently. Rain is opening the system up to a wider group of builders.
OpenClaw and AI Agent Integration
NVIDIA CEO Jensen Huang recently described OpenClaw as part of a broader shift in AI, from systems that answer questions to ones that can perform work. OpenClaw lets us have a personal agent, much like Microsoft let us have a personal computer. Rain 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 $5 million 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.
The program also gives builders a direct path to participate in the category's growth. Every builder earns a flat 0.5% share of the trading volume they generate. The commission is paid directly from Rain's token allocation, creating a predictable revenue stream for builders who drive activity on the platform.
CEO Commentary
“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.”
About Rain
Rain is a decentralized protocol that provides the infrastructure for anyone to build their own prediction market platforms or applications. Using the machine-readable Rain SDK, developers and AI agents can launch independent markets and niche apps. Rain features private, invitation-only markets, AMM, account abstraction, AI market and dispute resolution, cross-chain support, and more. For more information, visit the official website.
