About

Kalshi is a federally regulated derivatives exchange built for quants. Kalshi’s markets are volatile and settle daily, which means even a small edge can be extremely profitable. Trading is fully-cash collateralized, so you can never lose more than you put into a trade, and contracts can be purchased for as little as $0.01. Kalshi supports trading through its native app (iOS & Android), website, and API. The latter features extensive documentation, open-sources sample code, and live technical support. Getting started with an algorithmic strategy is as easy as `pip3 install kalshi_python`. The following data is available for free on both the website and API: * Historical spreads: Use past pricing data to set up back-tests within minutes. * Low-latency broadcasts: Receive live updates of market price movements and trade executions. * Economic projections: Build strategies using Kalshi’s proprietary forecasting tools.

About

Predictefy is a prediction-market data and trading infrastructure platform for developers, algorithmic traders, and research teams. Its REST API and SDKs provide a normalized way to retrieve market catalogs, prices, order books, trades, and historical data from supported venues. Users can stream live market updates over WebSockets, compare related markets across venues, and access market-matching and price-discrepancy data. The platform also documents order-building and execution workflows, portfolio and trader analytics, and tools for building automated strategies and AI-agent workflows, including an MCP server. Venue capabilities vary, and some analytics or data features depend on the subscription plan. Predictefy is designed for software teams and traders building research tools, trading bots, market monitors, and applications that use prediction-market data.

Pros & Cons from Real Users

Pros

  • Nothing.
  • Kalshi is great - it lets me take positions based on my interests and preferences that I can't take on any other exchange. It's a great way to trade on my belief of certain market factors without taking unknown risks.
  • Trading on the S&P and Nasdaq markets has been useful to generate daily income consistently. The strike prices are kinda similar to Iron Condor options, but easier to understand. The extended trading hours 7 days a week are sweet + the volume incentive program is pretty sick!
  • Fast execution, low fees, user-friendly interface, real-time data, diverse assets, secure, reliable.
  • Great clean interface. I really enjoyed browsing through the markets and learning about them. It's a pretty unique place to be honest because you are trading on events and their probability of happening. I used to work in finance and I would have killed to have had access to this when we were hedging our portfolio's or had strong macro views.

Cons

  • Ok this Kalshi officially has the worst customer support ever. Only email (have sent 8 emails so far).
  • None really, besides some markets needing some additional liquidity
  • Small feedback: Support larger deposits and faster transactions.
  • Limited API calls, steep learning curve, lack of order groups, occasional downtime, requires coding.
  • Downside is that there are too many great markets for me to trade at one time. Honestly, if you have a view on the world you will find it on Kalshi and then put your entire deposit into it and at least in my case, make some money. Issue is, you will in no time find another market you want to get in to.
