Excited to share I’ve joined DraftKings, working on our expansion into prediction markets with a focus on market making.
I’ve wound down @PrediDesk as I start this new role, appreciate all the support. Looking forward to staying connected with everyone in the space.

The launch of DKeX is a big deal for @DraftKings and gives them a meaningful edge over @FanDuel.
Having your own in-house exchange provides many clear competitive advantages that are often overlooked.
1. You can list your own markets.
2. You control 100% of the exchange economics.
I expect the trend of sportsbooks/brokers creating their own in-house exchanges (like @RobinhoodApp with @RotheraMarkets) to continue throughout the next few years as these advantages become even more obvious.
.@DraftKings today announced the launch of DKeX, DraftKings’ proprietary prediction markets exchange, with integration into the unified DraftKings: Sports & Casino app, further advancing the DraftKings Predictions experience.
DKeX marks the next phase in DraftKings’ prediction markets evolution, strengthening its ability to deliver differentiated sports experiences across the country alongside its leading sportsbook.

NBA Finals Game 1 delivered the biggest active customer day in DraftKings Predictions history.
Bigger than the Super Bowl.
That's the power of bringing sports experiences nationwide. And we're just getting started.

...aaaaaaand Polymarket just announced the same thing.

I have a new definition proposal for the gambling or not debate:
1) GAMBLING = zero-sum markets that are entirely luck based (roulette, slots, etc.) or where skill is deterministic (blackjack)
2) SPECULATION = zero-sum markets that have a non-deterministic skill component (prediction markets, weather derivatives, options, etc.)
3) INVESTING = markets that are not zero-sum (stocks)
Thoughts? 👂

This is a nice read, but I disagree with the "gambling-or-not" logic. Highlighting EV and luck vs. skill breezes over the mechanics of prediction markets that classifies them as gambling.
Prediction markets are 100% gambling because they are zero-sum (technically negative-sum after fees) and do not have underlying intrinsic value (yes, the information we gain from them has value, but a prediction contract itself is not a productive asset like a stock for a company).
Can we all please just embrace this fact. 🙏
