MarketParity

About

MarketParity finds the same economic exposure wherever it trades, across every kind of market, and shows what the difference is worth after fees. A Fed decision traded as an event contract, and the Treasury ETFs that move on it. An S&P 500 contract, and the options spread that pays the same way. Bitcoin spot, and its futures. A product launch, and the stock it moves. MarketParity matches them across venues and asset classes, checks whether the payoffs really line up, and prices the gap. When buying both sides pays out whatever happens, it shows you the lock: what it costs, what it pays and when. EVERY KIND OF MARKET • Stocks and ETFs: Treasury bonds, currencies, natural gas, sectors, and bitcoin and ether funds • Index options on Cboe, including the S&P 500 and Nasdaq-100 • Crypto spot, futures and perpetuals on Bitstamp, Kraken, Gemini, Deribit and OKX • Event contracts on Kalshi, Polymarket and PredictIt HOW MARKETS CONNECT • Same exposure: one position listed on two venues, or a contract and its mirror image. • Replicated: an options spread, a futures carry or a one-winner set that pays like it. • Linked: markets that imply, rule out or move with each other, such as a rate-cut contract and short-term Treasuries. THE BOARD • Thousands of pairs, refreshed every 5 minutes. Each shows both legs with bid and ask, the net edge after fees, and how sure the match is. Pairs matched by a model rather than exact rules are labelled. • "Locked in now" lists trades the books fill right now that pay out whatever happens, with the cost, the profit and the payout date. • Filter by kind (same bet, replicated, hedges, move together, stocks, crypto, one-winner sets) or by topic, and search by venue, symbol or contract. EVERY MATCH • Open a pair to see both sides together, with live quotes and a link to each venue. • See what a lock pays and when, the gross and net edge, and how the two markets relate. • Rate a match Good or Off. Your ratings help train the matcher. ASK Ask is an AI assistant that reads the live board for you. • "Where is this cheapest?" Compare venues' prices for the same position, fees included. • "Which locks pay the best return a year?" Get the best locks ranked, with cost, profit and payout date. • "What does a rate-cut contract say about Treasury ETFs?" See how two markets are linked and which way they move. • "I hold this position. How do I lock it in?" See what each outcome pays before you trade. • "Do both legs settle the same way?" Ask reads each venue's contract terms, from options and futures to event contracts, and points out where they differ. Answers come with cards for prices, payoffs and locks, and every match an answer names opens with a tap. A free account includes 100 questions a day.
