Why a calendar of resolving Polymarket markets matters

Polymarket lists thousands of binary and multi-outcome contracts at any given moment, but they all share one feature: a resolution date. Markets in their final week typically see the tightest YES + NO spreads of their entire lifecycle, because the information advantage of late traders compresses the gap between probability and price. That compression is exactly what intra-market arbitrage feeds on.

Our calendar surfaces every active contract by its UMA settlement day, so you can pick a date — say, April 21 2026, May 15 2026, or June 30 2026 — and instantly scan the full set of markets ending that day, ranked by 24-hour trading volume.

For traders new to Polymarket arbitrage, the playbook is straightforward: open a day-page, look for any binary contract where YES + NO sums to less than $0.98 (giving you a margin of safety after Polymarket's 2% taker fee), execute both legs as fill-or-kill taker orders, and let UMA settle. The PolyArb bot automates that loop with a 40ms median latency — vs. ~800ms for free competitor bots — and the autonomous AI agent on the $199/mo plan handles the entire workflow without you touching the order book.

FAQ

What does "ending soon" mean for a Polymarket market?
On Polymarket every contract has a resolution date — the day the underlying question is settled by the UMA optimistic oracle. Markets in the days approaching resolution typically see compressed YES + NO spreads, sharper liquidity, and the highest-frequency intra-market arbitrage opportunities of their lifecycle. PolyArb pre-builds a calendar page for every day from April 21 2026 through June 30 2026 (71 days total) so you can scan everything settling on a given date in one place.
How are these calendar pages updated?
Every page revalidates on disk every 30 minutes by hitting the Polymarket Gamma API directly with end_date_min / end_date_max bounds for that calendar day (UTC). Markets are sorted by 24-hour trading volume so the most liquid contracts surface first. New markets are listed throughout the week, so a date that looks light today may grow significantly closer to resolution.
Why focus on markets ending soon for arbitrage?
Two reasons. First, the closer a market is to UMA settlement, the tighter the YES + NO sum theoretically must be — converging on $1.00 — so any divergence below $1.00 is a near-deterministic arbitrage edge. Second, time-bounded contracts force traders to take positions, which thickens the order book and reduces slippage on each leg. PolyArb's bot accounts for the 2% Polymarket taker fee, slippage on both legs, and the UMA settlement window when ranking signals.
Are all dates in this calendar indexable by Google?
Yes — all 71 day-pages are listed in our sitemap with hreflang="en" and x-default both pointing to the EN URL, plus full robots: index, follow metadata. The pages render server-side with live Polymarket data so crawlers see fresh prices and spreads on every visit.
