Polymarket US has driven recent trader attention through record October activity, including 74 million trades and roughly $10 billion in volume fueled by expanded sports contracts and parlay-style products that accounted for over half of activity in peak weeks. Monthly active users hit an all-time high near 478,000, reflecting rapid adoption since the CFTC-regulated platform's 2025 launch and 2026 growth from sub-$100 million weekly volumes. However, overall prediction-market share has fallen sharply to around 27 percent as Kalshi captures the majority of regulated volume, while a late-October security incident involving a third-party provider briefly halted international trading and drained about $2.6 million in user funds before full reimbursement. Upcoming catalysts include potential POLY token developments, sustained sports momentum into year-end events, and any regulatory or competitive shifts that could influence visibility.
如果 Polymarket 在市場建立至 2026年12月31日 ET 期間的任何時間,達到至少指定的每日心智佔有率,且 Kaito Information Markets Arena 頁面(https://kaito.ai/mindshare-arena/infomarkets)顯示符合條件,則此市場將判定為「是」。否則,此市場將以「否」結算。 此市場僅會根據 Kaito Info Markets 頁面(https://kaito.ai/mindshare-arena/infomarkets)所示的 Polymarket 心智佔有率百分比之已定案每日結果進行判定;具體而言,採用「Historical Data」下 Polymarket 的每日數值。後續日期的數值公布後,該數值即視為最終結果。 此市場的判定來源為 https://kaito.ai/mindshare-arena/infomarkets 上的 Kaito Info Markets 頁面。如果在檢查時無法取得此判定來源,此市場將維持開放,直到 Kaito Info Markets 頁面恢復上線,並以恢復上線後的首次檢查結果進行判定。如果該頁面永久無法使用,此市場將根據最新可用資料進行判定。 注意:此市場的判定來源為 Kaito Info Markets 頁面(https://kaito.ai/mindshare-arena/infomarkets),該頁面以精確至小數點後兩位的百分比呈現平台的心智佔有率(例如 66.56%)。因此,結算此市場時將採用此精確度。
