One prediction market prices this story:
- Solana (SOL) — the market puts it at 23%, with $186 traded in the last 24 hours, closing 1 Jan 2027. The market resolves to Yes if Solana's price increases during 2026. It resolves to No if the price does not rise at any point in that year. Readers often mistake the linked news story about JPMorgan for the resolution criteria, but only the asset's actual return matters.
