Polymarket vs Sporttrade, 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. Sporttrade is a different kind of product: a sports-focused peer-to-peer betting exchange where participants took opposite sides of moneylines, point spreads, totals, and props against one another rather than against a house. Founded in 2018 and based in Philadelphia, it received its first state license in New Jersey in 2022 and went on to operate in five states, but in May 2026 it ceased its US online sports wagering and refocused on an application to the CFTC to run as a federally regulated exchange.

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 Sporttrade side by side on the dimensions that actually differ. Each cell describes a current fact as of 2026. Fee schedules, available markets, regional access, and regulatory details all change over time, and Sporttrade in particular is mid-transition with its consumer product paused, so treat each platform's own published terms as the authoritative source.

Prices and what they say about probability

The two present prices on different scales, but the underlying idea is the same. 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. Sporttrade priced each sports contract from zero to one hundred dollars, so a contract trading at 60 implied roughly a 60 percent chance, settling at 100 if it won and 0 if it lost. Both let prices move continuously and both let a holder exit before the event finished, so the quote at any moment encodes the market's live read on the outcome. The difference is what sits behind the quote: Polymarket prices form in an on-chain order book settling in USDC, while Sporttrade prices formed when two participants agreed on a sports line inside a state-regulated exchange. For how to turn a price into a probability, the explainer on reading implied probability on Polymarket works through several examples.

Coverage, settlement, and how positions clear

The two platforms cover very different ground. Sporttrade was sports only: moneylines, point spreads, over-under totals, and player or game props, each resolving on the official result of the game it referenced. Polymarket carries 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, so the trades and balances are inspectable on-chain, which is the property that lets Cent Signals read Polymarket activity at all. Sporttrade settled in US dollars on the official sporting outcome inside a state-regulated wagering framework, with activity private to the platform rather than posted to a public chain. Its planned CFTC designation would shift that settlement into the federal event-contract category overseen by a designated contract market and a clearing organization.

Fees and the commission model

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. Sporttrade built its model around a commission rather than a traditional sportsbook margin: because it matched traders peer-to-peer rather than acting as the counterparty, it charged a two percent commission on net profit only and took no fee on losing positions. That is a different economic model from a sportsbook, which earns the margin between the odds it posts and the true probability of an outcome. Both fee structures move over time, and Sporttrade's future schedule will depend on the terms of any CFTC-regulated relaunch, 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

The two arrived at the CFTC's event-contract framework from different directions. Sporttrade began as a state-licensed sports operator, with its first license in New Jersey in 2022 and operations in Arizona, Colorado, Iowa, and Virginia, but it found the state-by-state model slow to scale. In early 2026 it filed applications with the CFTC to register as a designated contract market and a derivatives clearing organization, the materials were posted publicly in February 2026, and in May 2026 it halted its state-licensed online wagering to concentrate on that federal route. As of mid-2026 it has no live consumer product and the review timeline is not fixed. Polymarket's international on-chain market has historically geoblocked US users, while its CFTC-regulated US exchange launched in December 2025 and treats event contracts as financial derivatives. The guide on whether Polymarket is gambling covers that debate, the Polymarket vs Kalshi comparison sets it against another CFTC-designated exchange, and the Polymarket vs Novig comparison looks at another sports exchange moving into the federal category.

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 Sporttrade. 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.
