Kalshi

Kalshi is the first regulated prediction market in the United States, allowing people to trade on the outcome of real-world events. Behind the scenes, its developer platform and APIs make it possible to build integrations and extend prediction markets into new applications.

Because prediction markets are an entirely new category, developer experience is critical to adoption. Kalshi needed documentation that would not only explain how their APIs work but also make it intuitive for developers to experiment, learn, and integrate quickly.

With Mintlify, Kalshi delivers that experience. An interactive API playground allows developers to try trades directly, lowering the barrier to entry. A built-in AI assistant helps answer questions in real time, keeping developers in a self-serve flow instead of pinging support. And with changelogs surfaced alongside documentation, developers can stay on top of the latest updates without context switching.

With Mintlify, Kalshi helps developers discover what’s possible faster and ultimately drive broader adoption of its prediction markets.
