Polymarket vs NovaPredict

NovaPredict positions itself with bonuses, social feeds, and a broad event catalog, accepting crypto deposits and paying out in kind. Polymarket is a pure prediction market: no bonuses, no house, no orders against the venue — every price is a resting limit order on a 250ms-captured book.

The difference in data is the takeaway: NovaPredict is a betting operator, so its record is a ledger of wagers; Polymarket is an exchange, so its record is a full order book that anyone can audit.

A betting platform sets odds and fills against those odds; its "price" reflects its own book and bonus conditions. Polymarket prices emerge from competing limit orders, and because none of those orders trade against a house, the executable price tracks the reference and reprises in sub-second windows after a print.

The measured version of that structure is in the archive: one-sided books 16.9% of the time, a 98.6% bunched-on-grid rate, and the 26-second family collapse recorded across coins — none of which appear in an operator's P&L.

NovaPredict settles according to platform rules around its bonus terms and payout policies. Polymarket settles each contract to USDC against a reference price at a fixed UTC timestamp, and the archive stores the winning outcome on every row — so settlement is data, not a support ticket.

For studies, that makes the Polymarket record citable: the settlement corpus of 298 resolved BTC contracts was measured directly from stored final-second books, something a wager ledger cannot reconstruct.

NovaPredict offers consumer-facing dining and social avenues; historical full-L2 depth is not its product. Polymarket's official API is free for live state and 1-minute price history, and recorded 250ms books with prices and metrics are available from the archive in CSV, JSON, and Parquet.

If the goal is to backtest outcome markets, the choice is clear: fill-level replay wants a real order book, and only the order-book venue provides the frames.

Choose NovaPredict for a consumer bonus-driven betting experience across a wide event catalog. Choose Polymarket for disciplined, fee-free, auditably-settled outcome trading with sub-second depth.

As always on this site, the recommendation separates the game from the market: bonuses are a game, a naked limit order on a real book is a market.
