Market context
The live tally will be driven by Elon Musk’s **main-feed posts, quote posts and reposts** on X between 31 July and 7 August 2026, with replies excluded unless they appear on the main feed and are captured by the tracker. For a programmatic read, the cleanest approach is to poll a dedicated tracker such as MuskSense or MuskMeter and reconcile it against the contract’s exact inclusion rules, because deleted posts only count if the tracker records them within roughly five minutes. [1][5]
Recent comparables point to a wide posting range rather than a stable daily cadence. Tracker-style outputs from late July show very high single-day activity, including 54, 55, 62, 64 and 76 posts on individual days, while market commentary on the prior week’s contract put the 160–179 and 180–199 bands in contention at one snapshot, implying that totals can swing quickly when Musk is active. [3][4][9][10][12] That history is why the current crowd-implied 0% YES is best read as a market-price statement, not evidence that the event is impossible. [2]
The key catalysts are mundane but decisive: travel, product announcements, Tesla or SpaceX updates, and any burst of political or platform-related commentary can lift the count sharply, while a quiet stretch can keep the total below higher bands. Traders watching this mechanically typically monitor whether the tracker’s intraday pace resembles the late-July run-rate, whether weekend behaviour persists into the settlement window, and whether any X-side changes affect what the capture tool records. [1][2][6]
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Bot UK, 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
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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 does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
