Elon Musk # tweets May 15 - May 22, 2026?

Platform comparison

Market context

Elon Musk's X posting frequency has become a measurable market variable. This contract tracks his main feed activity—posts, quotes, and reposts—over an eight-day window in May 2026, excluding replies unless they appear on his main feed. The current Polymarket pricing reflects near-zero conviction that any specific threshold will be breached, with conditional tokens trading at minimal USDC valuations on Polygon. The settlement hinges on tracker capture within approximately five minutes of posting, meaning deleted content counts if archived in time.

Musk's historical posting patterns show substantial variance. During periods of active Tesla or SpaceX developments, he has posted 20+ times daily; during quieter stretches, he has gone days with minimal activity. The May 2026 window carries no announced major product launches or earnings dates for Tesla, which typically correlates with elevated posting volume. His X engagement has remained consistent despite regulatory scrutiny and advertiser dynamics, though posting intensity fluctuates with news cycles and personal focus shifts between his various ventures.

Traders should monitor late April and early May announcements from Tesla, SpaceX, or xAI regarding product timelines or earnings calls scheduled near the settlement window. Any major geopolitical event or regulatory development affecting his companies could drive posting behaviour. The current 0% probability reflects either genuine uncertainty about threshold definitions or minimal market participation; historical volatility in his posting frequency suggests meaningful probability mass should exist across multiple outcome brackets.

Is this market available outside the US?

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.

Do I need to KYC for this market?

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

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.
