PredictRips vs Polymarket: a Polymarket alternative without the order book
In short
Who picks the market
On Polymarket you choose the exact market, the side and the amount. In a PredictRips pack you choose the pack (sport, crypto, politics or a mix, and its price) and the 3 positions inside are drawn at random from that pack's live pool.
What it costs
On an exchange the cost is the bid-ask spread, plus a fee on some markets, and you can trade any size. A PredictRips pack has a fixed price ($2 to $50) and a disclosed house edge: pack value at open is about 90% of the price, and held to the result a pack returns about 89% on average. The first pack is free.
Cashing out
On Polymarket you sell shares to another trader at the live bid. On PredictRips each card can be sold back at the live bid (about 85% in USDC or 92% as pack credit) until 2 minutes before its market closes, or held to the result, paying $1 a share if right.
Money in and out
Polymarket settles trades in a dollar stablecoin, and access depends on where you live. PredictRips takes stablecoin deposits on several networks (USDC, USDT, DAI and PYUSD on Base, Arbitrum One, BNB Smart Chain, Polygon PoS, OP Mainnet, Avalanche C-Chain, Solana (SPL) and Ethereum), keeps balances in USDC and pays withdrawals in USDC to your own wallet.
Which one suits you
If you have a view on a specific question and want to size your own trade, use an exchange like Polymarket. If you want a quick, fixed-price way to hold a few live markets across sport, crypto and politics, with the odds shown first, packs are the alternative. Both are for adults; packs are gambling with a house edge.
