US gas prices this week

Each of the 21 outcomes corresponds to a specific national average retail price range (a price 'bin') for regular gasoline during the settlement period; the market page and contract terms list the exact labels and numeric boundaries that determine which bin will settle.

'Closes: TBD' means the final trading deadline has not yet been published; trading remains open until Kalshi posts the official close time, and that timing can affect access to last-minute liquidity and the ability to react to late-breaking news—monitor the market page and platform alerts for updates.

The event's contract terms specify the primary settlement source (for example, a named government or industry dataset) and the exact timing used to determine the final price; check the market's rules on Kalshi to see the authoritative data series and settlement procedure.

Total volume shows how much money has been traded across outcomes to date and is a rough indicator of market participation and liquidity; higher volume generally means easier execution and faster incorporation of new information, but volume levels can change rapidly.

Unexpected developments—such as sudden refinery outages, major supply disruptions, extreme weather, or policy announcements—can shift the expected national average price and move market prices between outcome bins; traders typically adjust positions as such information becomes known, so intraday movement can be informative about shifting expectations.
