Polymarket SOL Data

SOL appears mainly in Up/Down contracts on 5-minute, 15-minute, and 4-hour windows — the format that dominates the crypto portion of the archive at roughly 62% — alongside smaller shares of price thresholds and event-linked markets. Every order book snapshot carries bid, ask, mid, top-of-book depth on both sides, and cumulative traded volume.

Because SOL five-minute markets are among the most actively created in the archive, historical coverage is continuous for long stretches, which makes it a good asset for multi-day order flow studies even when no individual market has research depth on the level of BTC.

SOL appears in the cataloged August 23 event in which ETH, BNB, DOGE, and SOL hit lower bounds within a 26-second window while Bitcoin's market took another 37 minutes. SOL's mid moved from 0.500 toward the 0.995 best-ask book as the event unfolded, with the order book leading the mid.

It is a small but revealing sample: for SOL, the measured evidence points the same direction as BTC and ETH — depth leaves first, prices follow.

• timestamp (RFC3339, UTC) and sequence number
• asset: SOL, and the contract ID
• bid price, ask price, and mid
• top-of-book bid and ask depth in contracts
• cumulative traded volume for the contract
• market type flag: Up/Down, threshold, or event-linked

The SOL series is included in the full archive, the order book history download, and the API. For live SOL prices Polymarket's own free API is usually the right answer; the archive holds the depth and history. A free sample of any single SOL market is available without an account.

• Pull SOL's frames for an August 23 window (the 26-second family collapse) and confirm the lower bound moved within that window; SOL is one of the four coins that repriced together.
• Compare SOL's reprice participation against BTC's 37-minute lag on the same event; the family contrast is the study, and SOL sits on the fast side of it.
• Measure SOL's one-sided frame share and round-grid share against the BTC baseline; the smaller coin typically shows the same texture at a lower depth, and the numbers should show why.
• Build a small cross-coin risk table (SOL, ETH, BTC, DOGE reprice seconds for a single event) — the same reference, four measured participation times, one honest comparison.

SOL is representative of the mid-size coin tier: high participation in family repricings (the measured 26-second collapse), thinner books than BTC, and the same 250ms-recorded structure as the majors — the coin where "smaller but same shape" is verifiable directly from the frames.

The liquidity story is in the depth columns: family events redistribute depth fast, one-sidedness is the norm, and SOL's measured role in the collapse — moving in step with ETH, BNB, and DOGE rather than lagging like BTC — is the empirical argument for tracking the whole family when you trade SOL.

SOL's measured role in every family table is the same: fast (26 seconds), joined (four coins together), and thinner than BTC — which is the exact description a reader of the SOL page needs before generalizing any SOL result.

SOL data is the mid-tier reference: the same Up/Down product, the same 250ms record, and a measured seat in the fast-moving half of the family collapses.

The lesson the SOL row teaches is participation in time — 26 seconds "with" ETH rather than 37 minutes "behind" BTC — and the archive records it as data, not commentary.

Study SOL as a family member first: reprice time, depth swing, and one-sidedness relative to the other coins are the columns, and the frames are the evidence.
