Market context
The event is whether Donald Trump posts on Truth Social often enough between 15 May and 22 May to clear the market’s threshold, using only main-feed posts, quote posts and reposts. A 0% crowd price usually reflects either a stale book or a technical view that the tracker will register at least one post, since Trump has remained highly active on social media around major political and foreign-policy developments. The current environment also matters for access: under Germany’s GlüStV, prediction markets can sit in a regulated gambling frame, while the US CFTC’s enforcement reach is relevant where platforms serve US-linked users. “No-KYC up to $1,500” means smaller positions may be opened without identity verification, which lowers friction for casual participation in this specific market, but does not change how the post count is resolved.
Recent comparables suggest looking at presidential travel, court deadlines, tariff announcements and conflict headlines rather than calendar noise. Trump’s online cadence has been driven by policy events, campaign-style messaging and reactions to breaking news, with bursts of posting possible in a single day and quiet periods still producing multiple reposts or quote posts. A recent Reuters report on 20 May described Trump linking foreign-policy developments and trade measures to his public messaging, while other coverage has continued to note volatile social-media use around the Iran-Israel conflict and tariff litigation. For this market, the main catalysts are scheduled remarks, cabinet or court developments, and any escalating overseas event likely to prompt rapid commentary on Truth Social before the 22 May 12:00 PM ET cut-off.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
