TLDR
- A partial government shutdown is expected as the House won’t vote on funding until Monday.
- Polymarket and Kalshi contracts focus on government shutdowns with differing specifications.
- A lapse in funding will occur if the House fails to vote on time before the deadline.
- Polymarket and Kalshi betting odds show high probability of shutdown lasting days.
The U.S. government stands on the brink of a partial shutdown due to the House of Representatives not being in session. While the Senate succeeded in passing a crucial funding package late Friday, the lack of action in the House means that a shutdown will officially take effect by midnight on Saturday, January 31, 2026.
Anticipations are that this shutdown will stretch through the weekend, potentially impacting government operations but not causing immediate widespread repercussions for most residents. This situation exemplifies the importance of precise definitions in prediction markets like Polymarket and Kalshi, where the nuances of what constitutes a shutdown can lead to different betting odds.

Despite the Senate’s passage of a funding package, the decision to delay voting in the House has led to an unprecedented situation where the government is technically in a state of shutdown. Unlike previous lengthy shutdowns—such as the significant 2018-2019 shutdown that lasted over a month—this partial shutdown highlights the immediate political challenges at hand.
Polymarket and Kalshi Contracts on Government Shutdown
Prediction markets like Polymarket and Kalshi offer unique contracts for individuals willing to wager on the likelihood and timing of a government shutdown. These markets underscore the vital role of clear and precise definitions in event-based betting.
For instance, contracts on Polymarket require that the U.S. Office of Personnel Management (OPM) must officially announce the shutdown for bets to resolve positively. This stipulation adds complexity, laying bare the difference between when the government is in a state of shutdown and when that shutdown is formally acknowledged.
Just earlier on Friday, Polymarket indicated an 88% probability of a shutdown, a significant jump from 40% the previous day. Kalshi’s comparable odds were even higher at 93%. These fluctuating figures highlight how quickly the landscape can shift based on the latest political developments, though the critical distinction remains that OPM has yet to make an official announcement regarding the shutdown.
Specificity in Shutdown Prediction Markets
Prediction markets like Polymarket and Kalshi also provide crucial insights regarding the expected duration of government shutdowns. Polymarket features contracts that hedge on how long the government might remain closed, focusing on specific outcomes such as one, two, or three days. As of Friday evening, odds for these contracts were at or above 90%, suggesting a strong consensus among bettors regarding the likelihood of a multi-day shutdown.
Kalshi displayed similar patterns in its odds, consistently projecting that users believe the shutdown will extend for at least two days. Such data showcases how bettors analyze various elements influencing the shutdown’s duration and its economic implications.
While the current partial shutdown is seen as less likely to produce long-term economic ramifications, the behavior within these prediction markets illustrates that bettors are vigilantly monitoring the evolving political scenario and adjusting their strategies accordingly.
Lapse in Funding and the House’s Role
The latest odds from prediction markets indicate an extraordinary 99.6% chance of a funding lapse occurring by 11:59 PM ET Friday. This lapse is contingent upon the House failing to pass the necessary funding bill before the deadline. As it stands, this funding lapse is now more likely to happen after the House reconvenes on Monday, shifting the focus of these markets to the actions taken next week.
As the deadline passes without a vote, sudden shifts in the political landscape could further affect the ongoing prediction market odds. Bettors are carefully assessing the broader implications even of this partial shutdown, understanding that the stakes could be higher if the House continues to delay its decisions. Given the nature of these political dynamics, anticipation remains high regarding the next steps and their potential influences on the market.
