Altcoin Markets 2026 — SOL, XRP and DOGE

Bitcoin and Ethereum have their own pages in this catalog. Everything below them, Solana, XRP and Dogecoin, turned about $26,900 across Polymarket and Kalshi in the past day, most of it on Dogecoin's $1 board.

These are all cumulative ladders: each rung asks whether a price is reached, so probabilities must fall monotonically as the strike rises. Every inversion on this page is a violation of that constraint, not a difference of opinion.

Solana's ladder leans down. Polymarket's 2026 touch ladder prices ↓80 at 69.5% and ↓70 at 37%, the rung nearest even. The upside is thin: ↑140 is 7%.

XRP's downside leads too. Polymarket's ↓1.00 is 66.5%, and Kalshi's year-high book has Above $3.00 at 5%, against Polymarket's ↑2.60 at 3.8%.

Polymarket's 2026 touch ladder, $2,302 in the past day, prices ↓80 at 69.5%, ↓70 at 37%, ↓60 13.75% and ↓50 5.85%. On the upside, ↑140 is 7%. ↓60 was the busiest rung at $655, just ahead of ↓70 at $637. Downside outweighs upside by a wide margin.

Kalshi's year-end close ladder turned $272, pricing $50 or above at 97%, 100 or above at 41%, the rung nearest even, 150 or above at 8.5%, 200 or above 4.5% and 250 or above 3.5%. The rungs are now in order. Touch and close are different questions: the touch ladder asks about any point in the year, the close ladder only about December 31.

↑400 is 0.75% with no trades in the past day; ↑320 is 0.9% on $45. Both sit near the floor, in order, while the trade on Solana's ladder clusters on the downside rungs.

Kalshi's 2026 high book on the left, $2,527 in the past day: Above $2.00 prices 13%, the busiest rung at $579; Above $2.50 is 5.5% and Above $3.00 5%, with no trades. Its top is inverted: Above $3.50 and Above $4.50 both price 6%, above the lower $2.50 and $3.00 rungs.

Polymarket's 2026 touch ladder on the right turned $2,758 and prices ↑2.60 at 3.8% and ↑2.80 at 3.6%, close to Kalshi's $3.00 number at a lower strike. On the downside it has ↓1.00 at 66.5%, ↓0.80 at 19.5%, the busiest rung at $267, and ↓0.60 at 4.5%.

Dogecoin's $1 board: before Jan 1, 2027 at 1%, on $7,243, and before Jun 1, 2027 at 5.5%, on $9,493, together the busiest board on the page. Kalshi's 2026 return basket, $2,273 in the past day, prices every coin below one in three to finish the year positive: Chainlink 30%, Ethereum 25.5%, Bitcoin 20.5%, from 24% at the last review, Stellar Lumens 17% and Solana 16%. The Solana price history runs full width below.

• Solana at $70. The touch rung nearest even, at 37%, with $80 at 69.5%; Kalshi prices a year-end close at $100 or above at 41%.
• XRP at $3.00: Kalshi 5%, Polymarket 3.8% at $2.60. The cross-exchange gap has nearly closed.
• Kalshi's XRP top. Above $3.50 and Above $4.50 at 6% sit above Above $3.00 at 5%, an inversion on a rung that has not traded.
• The return basket, with Chainlink at 30% and Bitcoin at 20.5%, and under two months to year-end.
