Polymarket SOL Odds Today: Live Solana Up/Down Prediction Markets

How Polymarket SOL odds work — Solana Up/Down prediction markets, how share prices map to probabilities, and how to access SOL markets via PolyHistorical Pro.

Looking for Polymarket SOL odds today? Polymarket runs Solana Up/Down prediction markets across five timeframes — 5-minute, 15-minute, 1-hour, 4-hour, and 24-hour — that price the live probability of SOL closing higher or lower than its open. PolyHistorical now archives every order book snapshot from these SOL markets alongside its existing BTC and ETH coverage.

What Are Polymarket SOL Odds?

Polymarket SOL odds are binary prediction market prices. Each Solana Up/Down market has two outcomes — Up and Down — and traders buy and sell shares that pay out $1 if their side wins. Because of that payout structure, the share price is directly the implied probability the market is assigning to each outcome.

How to Read a Polymarket SOL Price

Prices on Polymarket are quoted in cents on the dollar between $0 and $1. The conversion to traditional odds formats is purely mathematical:

Polymarket price	Implied probability	Decimal odds	American odds
$0.10	10%	10.00	+900
$0.25	25%	4.00	+300
$0.50	50%	2.00	+100
$0.75	75%	1.33	-300
$0.90	90%	1.11	-900

Formulas: implied_probability = price and decimal_odds = 1 / price.

SOL Market Timeframes Covered

Polymarket runs three Solana Up/Down timeframes in parallel:

5-minute (5m)
15-minute (15m)
1-hour (1h)

    "https://api.polyhistorical.com/v1/markets",
    params={"coin": "SOL", "market_type": "1h", "limit": 10},
