Polymarket vs PredictIt, explained
By the Cent Signals editorial desk. Last updated June 2026.
Polymarket and PredictIt are two prediction-market platforms that price real-world events as probabilities, but they are built differently. Polymarket is a broad, international, on-chain market that settles in USDC and lists politics, macro, crypto, sports, and culture. PredictIt is a US-only, politics-only market that settles in dollars through a linked bank account, caps how much you can hold in a contract, and resolves centrally. Cent Signals is a free, independent desk that tracks Polymarket activity and explains how prediction markets price probability, not trading advice. This page reads as of 2026 and is documentation only, describing how each platform is structured rather than guiding any choice between them.
What these two platforms are
Both Polymarket and PredictIt let participants take positions on the outcome of future events, with each contract priced between zero and one dollar so the price reads as the market's implied probability. The mechanics differ in scope, settlement, and oversight. PredictIt is, as of 2026, a US-only market restricted to political event contracts. It operates under CFTC no-action relief and, after a July 2025 amendment, is run by the non-profit Prediction Market Research Consortium, with day-to-day service provided by Aristotle International. Polymarket is an on-chain market that settles in USDC on the Polygon blockchain and, in 2026, received a CFTC amended designation to operate a US-facing exchange alongside its existing international platform.
Cent Signals covers Polymarket specifically. It reads the public prices, volume, liquidity, and wallet activity on Polymarket and explains what those figures describe. If you are new to reading those numbers, the companion explainer on what Polymarket is and how it works walks through the basics first.
Feature comparison (as of 2026)
The table sets Polymarket and PredictIt side by side on the dimensions that actually differ. Each cell describes a current fact as of 2026. Fee schedules, position caps, regional access, and regulatory status all change over time, so treat each platform's own published terms as the authoritative source.
| Capability | Polymarket | PredictIt |
|---|---|---|
| Regulator and legal status (as of 2026) | On-chain market; 2026 CFTC amended designation for a US exchange | US non-profit under CFTC no-action relief, run by PMRC |
| Markets it can list | Politics, macro, crypto, sports, culture | Political event contracts only |
| Settlement asset and venue | USDC on the Polygon blockchain | US dollars via a linked bank account |
| Resolution source (as of 2026) | Decentralized oracle with UMA dispute system | Centrally published criteria on each market page |
| Per-market position limit (as of 2026) | No fixed per-market cap | Capped per contract (raised to about $3,500 in 2025) |
| Account and identity verification required | Partial (Wallet-based; fiat on-ramps may add checks) | Yes: US account with bank link |
| On-chain, publicly inspectable activity | Yes | Partial (Centralized records, not on-chain) |
| Available regions (as of 2026) | International, plus US exchange after 2026 designation | United States |
| Trading and withdrawal fees (as of 2026) | Category taker fees; makers pay none; US exchange flat taker fee | 10% of net profit, 5% on withdrawals; free deposits |
Yes, Partial, and the short value cells above describe the current state of each platform as of 2026. They are not ratings and do not rank one platform above the other.
Scope and position limits
The most visible difference is scope. PredictIt lists political event contracts only, framed as simple Yes or No questions about elections, nominations, and policy outcomes, and it caps how much a single person can hold in one contract. The July 2025 CFTC amendment raised that per-contract ceiling from about $825 to $3,500, pegged to the federal campaign contribution limit, and removed the older 5,000-trader limit per contract. Polymarket lists a much wider range across politics, macro, crypto milestones, sports, and culture, and applies no fixed per-market position cap, which is why public wallets can hold very large positions on its busiest markets. You can see that breadth on a US political market such as the Polymarket market on the 2028 Democratic presidential nomination, where the price reads as an implied probability.
Settlement and resolution source
How a market pays out is the other place the two diverge. On PredictIt, contracts trade between $0 and $1, settle in US dollars through a linked bank account, and resolve under centrally published criteria listed on each market page. On Polymarket, settlement is in USDC on Polygon and resolution happens on-chain through a decentralized oracle that uses the UMA optimistic-oracle dispute system, where token holders can propose and challenge an outcome before it finalizes. One settles through a centralized non-profit process and the other through an on-chain oracle. Because the figures Cent Signals publishes are snapshots of public Polymarket data, reading the methodology page explains exactly which public sources those numbers come from.
Fees and available regions
On fees, as of 2026, PredictIt charges no commission on an individual trade but takes 10 percent of the net profit on a market and 5 percent on withdrawals, with free deposits. Polymarket historically charged nothing to trade and has since layered in a taker-fee model that varies by category, while maker orders that add liquidity to the book pay no fee; its US exchange applies a flat taker fee. On regions, PredictIt is built for US residents trading in dollars, while Polymarket operates internationally through a crypto wallet and added a US-facing exchange after its 2026 designation. Both sets of figures move, so the platforms' own current pages are the authoritative reference. For the vocabulary used here, the glossary of prediction-market terms defines resolution, liquidity, and implied probability.
How Cent Signals fits in
Cent Signals is not a platform and not a place to take a position. It is a free, independent reading desk for the public data Polymarket exposes. It requires no account and no wallet, because it only reads and explains public data and never routes a trade. It indexes markets with real activity behind them and the wallets that transact large notional, then explains what the prices and positions describe. You can see that in practice on a market page such as the market on a 50-plus basis point Fed rate cut after the June 2026 meeting, or on a tracked wallet such as this Polymarket trader and the positions it currently holds. Those pages report observations of public data, never instructions.
Frequently asked questions
Are Polymarket and PredictIt regulated the same way?
No. As of 2026 PredictIt is a US-only political market that operates under CFTC no-action relief, run by the non-profit Prediction Market Research Consortium after a July 2025 amendment moved operation from Victoria University of Wellington, with day-to-day service by Aristotle International. Polymarket runs an on-chain market that settles in USDC on the Polygon network and, in 2026, received a CFTC amended designation to operate a US exchange alongside its existing international platform. The two carry different regulatory histories and structures.
What can each platform list, and what are the position limits?
As of 2026, PredictIt is restricted to political event contracts and caps how much one person can hold in a single contract; the July 2025 CFTC amendment raised that per-contract ceiling from about $825 to $3,500, pegged to the federal campaign contribution limit, and removed the old 5,000-trader-per-contract cap. Polymarket lists a far broader range, including politics, macro, crypto milestones, sports, and culture, and applies no fixed per-market position limit, so wallets can and do hold very large positions on major markets.
What fees does Polymarket charge compared to PredictIt?
As of 2026, PredictIt charges no commission on individual trades but takes 10 percent of net profit on a market and 5 percent on withdrawals, with free deposits. Polymarket historically charged no trading fees and has since introduced a taker-fee model that varies by category, while maker orders that add liquidity pay no fee; its US exchange uses a flat taker fee. Both publish current fee schedules, which change over time, so the platforms' own pages are the authoritative source.
How does each platform settle and resolve a market?
PredictIt settles in US dollars: each contract trades between $0 and $1, the winning side pays $1, and resolution follows centrally published criteria on the market page. Polymarket settles in USDC on Polygon and resolves on-chain through a decentralized oracle, using the UMA optimistic-oracle dispute system, where token holders can propose and challenge an outcome before it finalizes. One settles through a centralized non-profit process and the other through an on-chain oracle. Both publish their resolution sources, as of 2026.
Where can people use Polymarket and PredictIt?
As of 2026, PredictIt is built for US residents and links a bank account in US dollars, with no crypto wallet involved. Polymarket operates internationally as an on-chain market reached through a crypto wallet and, following its 2026 CFTC amended designation, runs a US-facing exchange as well. Available regions for both change as rules evolve, so the platforms' own current terms are the authoritative source.
Is Cent Signals affiliated with Polymarket or PredictIt?
No. Cent Signals is an independent editorial desk. It is not operated by, funded by, or partnered with either platform. It reads public Polymarket data and explains how prediction markets price probability. It does not accept orders, custody funds, route trades, or connect wallets, and any outbound links to either platform are reference only.
