Rain, a decentralized infrastructure protocol for prediction markets fully compatible with OpenClaw, has launched an AI agent-ready software development kit (SDK) and a $5 million grant program to enable developers to build independent prediction market platforms. The initiative is open to developers globally and provides tools and funding to create and operate markets directly on the Rain protocol.
Addressing Centralization in Prediction Markets
Prediction markets allow participants to trade on the outcome of events, with prices reflecting collective expectations. While platforms such as Polymarket and Kalshi have gained traction and market valuations approaching $20 billion, most remain centralized.

Developers are generally limited to interacting with markets created by the platform, rather than creating their own. Rain aims to address this limitation.
AI Integration with OpenClaw
The SDK integrates with OpenClaw, an AI agent framework that allows software to perform tasks autonomously.
NVIDIA CEO Jensen Huang has described OpenClaw as part of a shift in AI from systems that answer questions to those capable of performing work, comparing it to the personal computer revolution.
With the Rain SDK, AI agents can generate fully functional prediction markets from a single prompt, covering market creation, pricing, trading, liquidity, and settlement. The protocol exposes these components as modular tools that developers can combine to launch new markets without manual coding.
Grants and Incentives for Developers
Rain’s $5 million grant program is split into two parts. About $3 million will be allocated to individual development projects, with grants of up to $50,000 per project. The remaining $2 million will fund daily ecosystem rewards designed to incentivize ongoing activity and engagement across the protocol.
Developers who build on Rain can also earn a 0.5% share of the trading volume generated by their platforms, with payouts drawn from the protocol’s token allocation. The model provides a predictable revenue stream for independent builders.
“In the past year, prediction markets have become one of the most talked about sectors in the market,” said Roy Shaham, CEO of Rain.
According to him, the SDK is designed for OpenClaw and AI agents, allowing developers to turn a single prompt into a live prediction market. He added that the $5 million grant program, “nearly double the industry standard,” gives creators the resources to launch their own platforms and markets independently.
Why This Matters
Rain’s launch could change the prediction market landscape by letting developers create independent markets without going through centralized platforms. Its use of AI agents via OpenClaw allows faster, automated market creation, potentially making it easier for new entrants to compete.
