Polymarket vs PredictIt
For US Politics
Both Polymarket and PredictIt focus heavily on political prediction markets, but they are fundamentally different products. Polymarket uses USDC, has no position cap, and has global liquidity, but requires a waitlist and blocks New York. PredictIt uses USD, is available now in all 50 states, and issues 1099s, but has an $850-per-contract cap and charges heavy fees. This comparison breaks down which is right for you.
When to use each platform
- You want to bet more than $850 on a single outcome
- You're comfortable with USDC and crypto wallets
- You want global political markets (non-US elections)
- You want deeper liquidity on major US elections
- You're NOT in New York
- You're willing to self-report taxes
- You want access right now with no waitlist
- You prefer USD, no crypto required
- You're in New York (Polymarket blocks NY)
- You want automatic 1099 tax reporting
- Your typical position is under $850 per contract
- You value PredictIt's established 10-year track record

The fee structures are very different
Despite both being political prediction markets, Polymarket and PredictIt have completely different fee models: and the difference matters significantly at larger trade sizes.
Fee: $60 × 2% = $1.20
Paid immediately on trade entry
Same fee whether you win or lose
No withdrawal fee
Win: $100 − $60 = $40 profit
10% fee: $4.00 deducted from profit
5% withdrawal fee on $96 = $4.80
Total fees on a win: $8.80 (22% of profit)
On winning trades, PredictIt is more expensive. The 10% profit fee + 5% withdrawal fee can cost 15–25% of gross profit depending on how much you reinvest vs withdraw. Polymarket's 2% taker fee charged at trade entry is simpler and lower for large winning positions: though it's charged on losing trades too (PredictIt charges nothing on losses).
PredictIt's $850 cap vs Polymarket's no limit
PredictIt's $850-per-contract limit is the most constraining feature for active traders. On a major US Senate race, you're capped at $850 of exposure per candidate. On Polymarket, there's no such cap: you can build positions in the tens or hundreds of thousands on major markets.
In practice, the $850 cap means PredictIt is primarily for retail political hobbyists, not serious traders. Maximum theoretical gain on any PredictIt contract: ~$340 (buy 850 NO contracts at 60¢, win at $1.00 = $340 gross − 10% − 5%). Polymarket allows institutional-scale positions on the same markets.
However, the $850 cap also has one benefit: it limits your maximum loss. If you're a casual political follower who wants to put $100 on an election outcome, PredictIt's lower-friction entry (no USDC, no waitlist) and $850 cap make it appropriately sized for casual participation.
Common questions
Is Polymarket or PredictIt better for US politics trading? +
Depends on your needs. PredictIt: no waitlist, USD, 1099, all 50 states including NY, but $850 cap and heavy fees. Polymarket QCEX: deeper liquidity, no position cap, global markets, but waitlist, USDC required, NY blocked, self-report taxes. For scale and liquidity, Polymarket wins. For accessibility and simplicity, PredictIt wins.
Can you use both Polymarket and PredictIt simultaneously? +
Yes: many active political traders use both. Price differences between the same market on each platform create arbitrage: buy the cheaper side on one platform and offset on the other. The $850 PredictIt cap limits arb size, but 5–10¢ price differences on major markets occur regularly.
Why does Polymarket block New York but PredictIt doesn't? +
Polymarket's QCEX chose to block NY when it launched in December 2025, citing NYDFS regulatory risk. PredictIt operates under a CFTC no-action exemption from 2014: a different regulatory path that hasn't faced NYDFS challenges. The QCEX license triggered NYDFS scrutiny that PredictIt's older no-action framework avoided.
Does PredictIt have better liquidity than Polymarket on US elections? +
Not for major races. Polymarket has $100M+ volume on presidential elections: far exceeding PredictIt. PredictIt has better liquidity on state-level races and congressional markets that Polymarket doesn't cover at the same depth. For niche US political questions (specific House districts, gubernatorial primaries), PredictIt often has the only liquid market.
