Director of Markets @Underdog and Co-Founder of @UFO_Holdings

Milwaukee, WI
Joined October 2019
I just started work at @Underdog where I will be building the best exchange for sports fans. While opportunities in prediction markets are incredibly wide, the decision on where I wanted to work next was easy. The companies that will define this space long-term are the ones that know how to navigate changing regulatory structures, have a genuine obsession with building great products, backed by a record of doing so, and have a user base that already trusts them. Underdog hits all three markers, and I'd argue no one surpasses the company in any of the three categories. Further, Underdog is one of the only sports companies in the country that holds all three major CFTC licenses: DCM, DCO, and FCM. These licenses are a challenge to acquire and take time, capital, and regulatory credibility. Most companies in this space have one and piggyback on a partner who has another. Underdog went out and developed what it needed to operate independently and at scale, and that signals something important about where this company is headed. Underdog has been designing innovative products their customers obsess over for a long time and across multiple categories and regulatory regimes. They don't operate with any sanctimony about what the rules should be; they find ways to make incredible products for their customers within the relevant rules and regulations. Before they even had their own prediction market exchange, they figured out how to combine a federally regulated event contract with player picks from their fantasy product. At the time, this delivered a same-game parlay-like experience before anyone else. When I saw it, I knew I needed to talk to them, as this kind of creative problem-solving is exactly what separates good operators from great ones. Now, after the acquisition by IG Group, Underdog has even more firepower. We'll be able to leverage their expertise and resources to expand what's been created here to more customers, and keep building more incredible products. @JerLevine is another major reason I think Underdog has a real shot to lead this space. I've watched founders try to navigate prediction markets, and it's genuinely hard. The regulatory complexity, the product challenges, and the competition from companies with bigger balance sheets can turn it into a gauntlet. Jeremy has led Underdog through these challenges, and just does things the right way. Regulated markets and responsible gaming aren't afterthoughts here, they're baked into how this team operates. I'm excited to bring what I have learned to Underdog and help build at the most interesting company in prediction markets right now.

Watching the @Polymarket order book near the end of an NFL game is pretty incredible. Instantaneous price discovery happening with 0.25% precision!

Very interesting situation for the Yankees-Orioles doubleheader today! The MLB Press release and @Yankees both say: "Saturday's Yankees-Orioles game (Saturday, September 26) has been rescheduled due to the forecast of sustained inclement weather and will be made up tomorrow, Friday, September 25, as the first game of a single-admission doubleheader, which will begin at 4:05 p.m." The @MLB calendar shows precisely the opposite, with Saturday's Yankees-Orioles game being played as the second game. @Kalshi and others are treating the Saturday game as the first game today but other platforms are doing the opposite. Be careful trading today!
Saturday's Yankees-Orioles game (Saturday, September 26) has been rescheduled due to the forecast of sustained inclement weather and will be made up tomorrow, Friday, September 25, as the first game of a single-admission doubleheader, which will begin at 4:05 p.m. More details are provided in the graphic below.

My experience of building and operating a CFTC predictions exchange is that it's extremely difficult, technical work, operationally intensive in a way that is not obvious, and literally everyone who tries underestimates these aspects of running the business.

I need a DCM to list this market so I can hedge my personal exposure to this potential SCOTUS ruling. The first prediction market hedge on Kalshi was a SCOTUS ruling. xitter.cf/Nostroah/status/197059…
NEW: Kalshi won't offer a market predicting whether the Supreme Court will hear a case on sports prediction markets, a spokesperson tells me, nor will it list a market on a decision in that case. That means that Kalshi, which was was founded with the purpose of providing ways for traders to hedge their exposure to risk, won’t have a way to hedge against the biggest risk to the company’s business. If they did want to hedge that risk, they'd have to go to Polymarket. The international version of Polymarket has a "SCOTUS accepts sports event contract case by...?" market (43% chance by Dec. 31). There's no similar contract on Polymarket U.S., and a spokesperson didn't respond to a request for comment. The Kalshi spokesperson says that it could list a market on the Supreme Court’s actions, but is not doing so on principle. Since Kalshi is one of the parties in the case the Supreme Court is now deciding whether to hear, actions taken by Kalshi’s legal team could affect the outcome of a market on the court’s decisions. The platform does not allow people who can affect the outcome of a market to trade in that market, and Kalshi does not want to list a market that the firm itself could influence.

That light blue company did a lot in July and August!
Today we are launching the first ever CFTC API. As applications for product filings continue to grow (including all new regulated perps) we now offer a way to pull new filings and parse their documents.
