Prediction market participants are assigning meaningful probabilities to further price declines across major altcoins as crypto traders position ahead of year-end contract settlements on Polymarket and Kalshi.
Ethereum Carries the Highest Probability of Downside Move
Polymarket bettors place a 77% chance that ethereum touches $2,250 per coin before 2027 begins, with a 45% probability of reaching $2,000. ETH was trading at approximately $2,441 at the time of reporting.
On the upside, Polymarket odds put a 48% probability on ETH reaching $3,000, falling to 25% for $3,500, 15% for $4,000 and 6% for $5,000. A move to $10,000 is assigned just 2% probability.
Kalshi's year-end ethereum market, which uses mutually exclusive price brackets to determine where ETH finishes December 31, reports a forecast value of $2,610. The platform's ethereum contract has handled roughly $12 million in volume, while Polymarket's comparable market has seen about $12.9 million.
XRP Odds Split Between a Fall Below $1 and a Rebound Above $2
XRP was valued at $1.37 per unit at the time of reporting. Polymarket bettors assign a 73% chance of XRP touching $1.20 and a 40% probability of a drop to $1, with 16% odds on a slide to 80 cents.
On Kalshi, XRP's maximum-price market places the probability of exceeding $2 at 44%, above $2.50 at 29% and above $3 at 23%. These figures represent a more constructive outlook than Polymarket's comparable upside contract, though the two platforms use different settlement rules and data sources.
Solana Traders Expect a Wide Trading Range
Polymarket traders give solana, trading at approximately $101.41, a 67% chance of touching $90 and a 63% probability of reaching $120. Beyond those thresholds, odds thin sharply: 25% for $160 and 11% for $200.
Kalshi assigns a 35% probability of SOL exceeding $150, 30% above $160 and 28% above $170.
Methodological Differences Shape the Odds
The divergence between platforms is partly attributable to settlement mechanics. Polymarket uses Binance one-minute price candles for its event contracts, while Kalshi relies on CF Benchmarks indexes and proprietary settlement rules. Small differences in timing and methodology can determine whether a contract pays out.
Settlement Deadline Set for December 31, 2026
All referenced contracts settle by the end of the calendar year. Polymarket's markets resolve on whether specified price thresholds are touched at any point through December 31, while Kalshi's ethereum market resolves based on where ETH settles at year-end. The activity suggests traders are hedging across a broad range of outcomes rather than expressing a single directional view.
