Elon Musk # tweets August 11 - August 18, 2026?

Platform comparison

Market context

Elon Musk’s X activity over 11–18 August will be driven by how often he posts on the main feed, including quote posts and reposts, but not replies. The tracker for the comparable 4–11 August contract shows a crowded distribution rather than a single dominant outcome, with the market currently pricing the 180–199 bucket at about 35% and 200–219 at roughly 33%; a separate lines market shows the 200–219 bracket at around 15.5–16.5% and the “NO” side near 84.5%, underscoring how book-style odds can look very different from bucketed prediction-market pricing.[2][8]

Historically, Musk’s count tends to be high enough that modest windows can clear 100 posts quickly, especially when he is active on Starlink, Grok, SpaceX, Tesla, or policy topics, which is why traders treat his posting cadence as the main reference point rather than any single scheduled event.[2] MuskSense’s live tracker already has the next week’s market at 0 tweets before the window opens, but that should be read as a placeholder rather than a true forecast; the more useful comparison is that similar weekly contracts on Polymarket have often clustered around the high-hundreds rather than at extreme tails.[1][10]

For this contract, the main catalysts are routine rather than calendar-based: product announcements, earnings-related commentary, platform disputes on X, or sudden reactions to news can all push posting frequency materially above baseline. X itself remains the decisive resolution source if the tracker fails, so traders will want to watch for any unusually dense burst of quote posts or reposts once the window opens, because those count the same as original feed posts under the rules.[2]

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 Kalshi vs Polymarket, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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.

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.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi vs Polymarket trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
