Kalshi is a trading platform. It's been more reliable than the stock market in my experience.

In the times I traded sports contracts, I was able to reverse a trade during the event to prevent a total loss of contract investment, and buy back in if the momentum changed. But usually for the times I bought sports contracts and allowed it to complete, I was outperforming the stock market on a daily basis.

The only stock market trade that outperformed was BWET at the start of the Iran War.
