Kalshi’s latest market estimate put the probability of the Strait of Hormuz reopening by Sept. 1 at 6%, according to a chart published by Econbrowser. The post compared that event-market reading with Brent oil prices and a NYMEX cash quote, placing the July 16 NYMEX closing reading at $88 a barrel.
The chart tracked three series: Brent crude in dollars per barrel, shown against the left-hand scale; a cash NYMEX marker for July 17; and the Kalshi probability for reopening by Sept. 1, shown against the right-hand scale. Econbrowser cited the U.S. Energy Information Administration, NYMEX data via Barchart and Kalshi as the data sources for the figure.
Kalshi contracts allow participants to trade on whether a specified event will occur by a defined date. In this case, the event is a reopening of the Strait of Hormuz by Sept. 1. The resulting market price can be read as an implied probability, subject to liquidity, contract design and the balance of buyers and sellers in that specific market.
Econbrowser noted that oil prices and the reopening probability might be expected to move in opposite directions. Under that reading, a lower probability of reopening would normally be associated with higher oil prices, while a higher probability of reopening would normally be associated with lower oil prices.
The relationship did not appear to behave that way through roughly July 6, according to Econbrowser’s observation of the two series. The post described that divergence as unexplained, without offering a definitive reason for the pattern.
The data point highlighted in the post was the sharp fall in Kalshi’s Sept. 1 reopening estimate to 6%. The oil-market reference alongside it was the NYMEX cash reading of $88 at the July 16 close.
For investors and policy observers, the comparison illustrates how event-market pricing can be set beside commodity prices to test whether political or logistical risks are being reflected consistently across markets. Econbrowser’s chart does not establish causation between the Kalshi estimate and Brent prices; it presents the two series together and flags that their recent co-movement was not straightforward.
