Active sub-markets
Market context
Polymarket is pricing this Musk posting window at 7% for Yes, so the market is treating an unusually quiet stretch as the base case rather than a busy X feed. The contract settles in USDC on Polygon through conditional tokens, with only main-feed posts, quote posts and reposts counting; replies do not, apart from replies that appear on the main feed and are captured by the tracker. That makes the practical question not whether Musk will be active in comments, but whether he will put enough countable posts through the main account before 25 May 12:00 ET to move the tally into one of the higher brackets.
Recent comparable markets show how quickly the range can reprice once posting picks up. Earlier May contracts on the same account clustered much higher, with one market for 8–15 May centred on the 100–119 bracket at about 42%, while another for 23–25 May was led by 65–89 at 38% and 40–64 at 37%. Phemex reported a sharp intraday move in a separate Elon Musk tweet-count submarket, underlining how sensitive these contracts are to bursts of activity rather than broad sentiment alone. For traders, that history argues against reading the current 7% as a hard view on his overall posting habit; it is a snapshot of the specific window and the market’s expectation of whether he will be active enough, often enough, to clear the lower bands.
The main catalysts are simple but lumpy: product announcements, policy commentary, live responses to X or Tesla developments, and any high-profile external event that prompts a run of posts or reposts. Because the settlement window is short, a single busy day can dominate the outcome if it falls inside the countable period. Deleted posts still count if the tracker captures them for roughly five minutes, so fast deletions do not remove risk. Traders should also watch for any schedule-driven appearances or time-sensitive company news, since those are the sorts of triggers that have lifted recent tweet-volume markets before the window closes.
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.
FAQ

- On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
