- DFS contest players who want betting in the same wallet
Polymarket strengths

- Strong API + data feed; institutional-grade tooling
- Backed by top-tier VCs (Founders Fund, Vitalik) and operating since 2020
Polymarket trade-offs
- Geo-blocked in the US; users circumventing via VPN violate the platform ToS and face counterparty risk
- Self-custodial wallets carry smart-contract + key-management risk
- US sports coverage is shallower than Kalshi's vertical depth
- USDC settlement requires crypto on-ramp — adds friction vs ACH
- No US consumer-protection framework for disputes
DraftKings strengths
- Largest US sports betting handle and market coverage
- Tightest spreads/totals on major US leagues (NBA, NFL)
- Wide player-prop and same-game parlay coverage
- Mature mobile app with live streaming, cashout, partial-cashout
- Frequent promo offers — boosted odds, deposit matches, no-sweat first bets
DraftKings trade-offs
- Vig averages 4–5% on moneylines, much higher on parlays
- Limits sharps aggressively after sustained winning
- State-by-state availability — not legal in CA, TX, FL, HI, AK among others
- Geo-restricted; you must be physically in a licensed state to place bets
Polymarket vs DraftKings — where the EV lives
Polymarket is an event-contracts exchange — sports outcomes trade as YES/NO contracts at user-set prices. DraftKings is a state-licensed sportsbook — you're betting against the house at vigged prices. The structural difference means Polymarket and DraftKings regularly disagree by 3-10pp on the same market.
SportsBookISH overlays both side-by-side so the gaps are visible without manually pulling up two apps. Median absolute gap on major-league moneylines is around 3-4pp; the tails (10pp+ divergences) appear in roughly 5% of open markets and are usually where the meaningful edge sits.
