When I joined Kalshi back in 2020, the company had just received the regulatory designation it needed to act as a prediction market in the US (after years of work from @luanalopeslara and @mansourtarek_ ), but we still had to actually build the exchange. As an engineer, it felt like such a gift to be a part of that process: the whole team had such conviction in these markets. We dreamed of the day they would be hooked up to trading terminals and referenced by news anchors worldwide. I thought: “if we can just get the systems up and running, people will come.” When we processed our first trade, it felt amazing. But I was also hit with the reality that what we had was not enough: how could we scale to millions of markets a day? How could we support collateral return and margin on events? How do we make even low volume markets liquid? Unlike building a matching engine, these were (and some remain) open questions that hadn’t been solved by a financial exchange before. Thankfully, the team is composed of many of the most hardworking and passionate people I’ve ever met, so though tackling these problems has meant a lot of late nights, it’s never meant a late night alone (shout out to @_rainerds who has been my grinding buddy since the beginning). I'm so grateful to be working alongside each one of you. There is still so much left to do. If you’re interested in joining us, I’d love to chat!
