Catch every arb on May 31 2026 — before it settles
PolyArb scans every market resolving on May 31 2026 every few seconds. The instant a YES + NO spread clears the $7.62 edge floor, you get a Telegram and Discord alert with sizing — and the autonomous AI agent can take the trade for you.
Trading Polymarket markets that resolve on May 31 2026
Sunday, May 31 2026 is a busy day on Polymarket. 100 active markets are scheduled to settle, with $6,514,978 traded across them in the last 24 hours. Markets near their resolution date often see compressed spreads — the closer to UMA settlement, the more the YES + NO sum should converge to $1. That convergence creates the highest-frequency intra-market arbitrage opportunities on the platform.
The PolyArb bot uses a 40ms median latency loop (vs ~800ms for free competitor bots) to fire on every YES + NO mispricing the moment the order book ticks. Every signal we send is filtered by a hard floor: at least $7.62 net edge per trade after Polymarket's 2% taker fee, sized for $1,000 of capital. If you're trading from your own bankroll, the bot scales the suggestion using bankroll-aware Kelly sizing with a 2% per-leg cap.
For traders new to Polymarket, the playbook on resolution day is straightforward: scan the markets listed above, look for any binary contract where YES + NO sums to less than $0.98 (giving you a margin of safety after fees), execute both legs as fill-or-kill taker orders, and let UMA settle. The autonomous AI agent on the $199/mo plan handles the entire loop for you and posts a 2.7× guaranteed profit multiplier vs. manual trading.
FAQ
- What does it mean for a Polymarket market to "resolve" on May 31 2026?
- A Polymarket market resolves on May 31 2026 when its underlying real-world question is settled by the UMA optimistic oracle on that calendar day (UTC). Until resolution, YES and NO shares trade between $0 and $1; on the resolution date the winning side pays out at $1 and the losing side at $0. PolyArb tracks every market resolving on May 31 2026 so you can scan for last-minute arbitrage edges before settlement.
- How do I find arbitrage on Polymarket markets resolving May 31 2026?
- The simplest arbitrage signal is when YES + NO prices on the same Polymarket binary contract sum to less than $1 (after Polymarket's 2% taker fee). PolyArb's bot scans every market resolving on May 31 2026 every few seconds, fires Telegram and Discord alerts when net edge clears $7.62 per $1,000 of capital, and ranks the highest-volume opportunities first.
- How many markets resolve on May 31 2026?
- 100 active Polymarket markets are scheduled to resolve on May 31 2026, with combined 24-hour trading volume of $6,514,978. The list updates every 30 minutes — markets can be added or removed by the Polymarket team or by event reschedules.
- Is it safe to trade Polymarket markets close to resolution?
- Markets near their resolution date often have tighter liquidity but also more predictable outcomes — making them prime targets for combinatorial and intra-market arbitrage. PolyArb's bot accounts for fee drag, slippage on each leg, and the UMA settlement window when ranking opportunities. Always size with Kelly and keep at least one outcome cap per leg.
