WTI Crude Oil (WTI) Up or Down on July 13?

Platform comparison

Market context

WTI crude oil futures will either close higher or lower on 13 July 2026 than they did on the prior trading session. The market currently shows 100% implied probability for an up move, a reflection of either extreme conviction or illiquidity in the order book. Across platforms, this probability translates differently: Polymarket displays it as 1.01 decimal odds, whilst Kalshi and Smarkets would show near-identical implied probabilities but with distinct fee structures—Kalshi typically charges 2% on winnings, Smarkets takes 2% on stakes, and Polymarket applies a flat 2% fee on both sides. The gap between these fee models becomes material on markets with such tight pricing, where the true edge may be consumed entirely by settlement costs.

Single-day directional moves in crude oil futures are driven by overnight developments in geopolitical supply disruptions, OPEC+ production announcements, US inventory data releases, and macroeconomic signals affecting demand. The week of 13 July 2026 falls outside scheduled EIA inventory reports (typically released Wednesdays) and OPEC meetings, reducing scheduled catalysts. Traders should monitor any unplanned supply shocks, dollar strength movements, or equity market volatility that historically correlates with energy futures. The 100% probability suggests either the market is pricing in a known directional bias from prior-day price action or reflects thin liquidity; platforms with deeper order books (Betfair's sports-focused user base occasionally migrates to financial markets) may show materially different odds if significant volume enters.
