Crypto markets on Polymarket: Bitcoin and Ethereum price targets by date, hourly and daily up/down markets, ETF decisions, exchange listings, unlocks and protocol upgrades.
Because these markets settle against a public price feed, they are the cleanest read available on what traders actually expect — a 30% price on "BTC above $150k" is a real, tradeable probability rather than a forecast in an article.
Each outcome trades as a share priced between 1¢ and 99¢, and the price is the market's implied probability. A share at 40¢ means traders collectively give that outcome a 40% chance; if it happens, the share pays $1.00.
Are Polymarket Crypto odds accurate?
They reflect real money at risk rather than opinion, which historically makes them well calibrated — but they are a live forecast, not a guarantee, and thin markets can be moved by a single large trader. Check the volume column before trusting a price.
How often do these odds update?
Continuously. Prices come straight from Polymarket's public API and refresh as trades happen, with roughly 30 seconds of edge caching.
