The Big Difference
FanDuel Predicts is a CFTC-regulated exchange backed by CME Group. Your money moves in USD. Deposits via debit or ACH. Withdrawals back to your bank. Legal for all US residents.
Polymarket settles in USDC on the Polygon blockchain. You need a crypto wallet to participate. For US residents, access runs through Polymarket US rather than the international book — which cannot legally serve you without violating CFTC jurisdiction. Many US traders still participate, but the legal status is unresolved.
US Access: The Critical Issue
FanDuel Predicts: all 50 states, no workarounds required.
Polymarket: two separate venues. Polymarket US is a CFTC-designated exchange that has been open to US traders since December 2025 — it settles in USD, requires full identity verification, and its state coverage is still expanding. The international on-chain book, which carried the huge 2024 election volume, remains closed to US persons. The two do not share an order book, so their prices are not interchangeable.
If regulatory compliance matters to you, FanDuel Predicts is the only regulated answer.
FanDuel Predicts Strengths
- Sports contracts in 18 states
- Financial/macro markets (all 50 states)
- USD deposits and withdrawals
- CFTC-regulated, legal everywhere
- $25 free to start
Polymarket Strengths
- Global elections and politics
- Highest global trading volume
- Broadest international event catalog
- Crypto-native for Web3 users
- No US geographic restrictions (in practice)
Fees: Total Cost Comparison
FanDuel Predicts: 2% on payouts. No gas fees. No conversion costs. No spread on entry.
Polymarket: gas fees on Polygon + bid-ask spread on entry and exit. Total cost varies and isn't always visible upfront. On high-volume markets the spread is tight; on thin markets it widens significantly.
Additionally, Polymarket requires buying USDC and bridging to Polygon before you can trade — and converting back out when done. That friction adds time and cost that FanDuel Predicts doesn't.
Verdict: Who Should Use Which?
Use FanDuel Predicts if you're a US trader who wants fully regulated access, USD deposits, and sports + financial markets without legal exposure.
Use Polymarket if you're comfortable with crypto, want global political and international event markets, and are willing to operate in a legally ambiguous area as a US resident.
Most traders who use Polymarket also trade on Kalshi or FanDuel for US-regulated exposure. They serve different niches — there's significant reason to run both.
