Like other prediction markets, Kalshi lets users make trades based on a variety of different subjects and events. For example, you could participate in a market focused on the results of a basketball game, or something more unusual, like who'll win the current season of Survivor. Despite resembling gambling, online predictive markets aren't currently regulated by state gambling laws, and instead classify bets as a type of futures contract, placing them under the purview of the CFTC. That hasn't stopped states from trying to regulate prediction markets anyway. For example, Nevada sued Kalshi for operating a sports gambling market without a permit earlier in February.

But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.
