Most sports bettors never ask this: who am I actually betting against?

The answer changes everything. 🧵

1/ When you place a spread bet on DraftKings, you're not competing against other fans. You're betting against the house — a company whose entire business depends on the odds never being truly fair.

2/ The vig is already built in before you see the line. At -110, you need to win 52.4% of bets just to break even. Win exactly half? You lose money. Every time.

3/ Most bettors imagine it's like poker — outsmart the room, win. But there's no room. There's just a sportsbook that set the price, controls the margin, and never loses its edge.

4/ Prediction markets like Kalshi are different. You're trading against another person with a different view. Kalshi charges a flat fee and has no stake in who wins. That's a real market.

5/ The best bettors obsess over this question. Most recreational bettors never ask it once.
