Polymarket vs FanDuel, explained

What these two platforms are

Polymarket is an on-chain prediction market. Each contract is priced between zero and one dollar, so the price reads as the market's implied probability of an outcome, and positions settle in USDC on the Polygon blockchain. Its catalogue spans politics, economics, crypto, weather, sports, and other event categories, and in December 2025 it launched a CFTC-regulated US exchange alongside its existing international on-chain market. FanDuel Predicts is a separate, newer product from the sportsbook company, launched with CME Group on December 22, 2025. It lets eligible US users trade event contracts, simple yes-or-no questions priced from one cent to ninety-nine cents, where a correct contract pays one dollar at settlement. The contracts are listed on CME Group derivatives exchanges and held through FanDuel Prediction Markets LLC, a registered futures commission merchant, which is why FanDuel positions the product as federally regulated event-contract trading distinct from its state-licensed sportsbook.

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 FanDuel Predicts side by side on the dimensions that actually differ. Each cell describes a current fact as of 2026. Fee schedules, state access, available categories, and regulatory details all change over time, so treat each platform's own published terms as the authoritative source.

Prices and what they say about probability

The two share a core mechanic. On Polymarket, a YES share trades somewhere between zero and one dollar, and that price in cents reads straight off as an implied probability: a contract at 40 cents corresponds to roughly a 40 percent chance, and a matched pair of YES and NO shares is always backed by one dollar of USDC. On FanDuel Predicts, an event contract is likewise priced from one cent to ninety-nine cents and pays one dollar if the outcome happens, so the price carries the same probability reading. The difference is what sits behind the price: Polymarket prices form in an on-chain order book settling in USDC, while FanDuel routes its contracts to CME Group exchanges where prices form as users are matched against one another and FanDuel does not set the odds or take the other side. For how to read a price as a probability, the explainer on reading implied probability on Polymarket works through several examples.

Coverage, settlement, and how trades clear

The two platforms cover different ground. FanDuel Predicts leans on sports and headline event contracts at launch, the categories closest to its existing audience, with sports event contracts offered in states where FanDuel does not run a sportsbook. Polymarket carries a broad mix of politics, economics, crypto, weather, and sports, with many markets that stay open for weeks or months until an event resolves. Settlement differs too: Polymarket positions clear in USDC on Polygon and resolve through the UMA optimistic oracle, with a challenge window before a result is finalized, while FanDuel Predicts contracts are cash-settled in US dollars under the rules and settlement source published for each contract on the CME-listed exchange the trade clears on. Because Polymarket settles on a public chain, its trades and balances are inspectable on-chain, which is the property that lets Cent Signals read Polymarket activity at all; FanDuel activity, by contrast, is private to the broker and exchange.

Fees and account requirements

On costs, the two are structured differently. As of 2026, Polymarket has used a taker fee that varies by category while maker orders that add liquidity pay no fee, with no platform deposit or withdrawal fee, and its US exchange applies a separate flat taker fee. FanDuel Predicts has applied a 2 percent fee on both the initial trade and an early cash-out, charged through the CME-listed exchange the contract clears on, and it requires a verified US account opened through FanDuel Prediction Markets LLC, a registered futures commission merchant and National Futures Association member. Both sets of figures move over time, so the platforms' own current pages remain the authoritative reference. For the Polymarket side in detail, the Polymarket fees explainer breaks down the category taker fee and where it peaks.

Regulation and where each is available

Both describe themselves as CFTC-overseen event-contract venues, but their footprints differ. FanDuel Predicts launched on December 22, 2025 in a small set of states and expanded its event-contract availability across US states through early 2026, with sports event contracts limited to states where FanDuel does not operate a sportsbook. It is structured as federally regulated event-contract trading rather than state-licensed sports betting, which is why its availability map differs from the FanDuel sportsbook. Polymarket's international on-chain market has historically geoblocked US users, while its CFTC-regulated US exchange launched in December 2025 treats event contracts as financial derivatives rather than wagers. The guide on whether Polymarket is gambling covers that debate, the Polymarket vs DraftKings comparison sets it against the other sportsbook entrant, and the Polymarket vs Kalshi comparison sets it against a CFTC-designated exchange.

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, and it tracks Polymarket specifically rather than FanDuel. 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 on the markets worth a second look index, 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. For how the figures are collected, see the methodology page.
