Next is Before Mar 1, 2027 at 73.5%. The venues list this event, but none of their outcomes are matched yet, so prices are shown separately.
Consensus blends each venue’s last price, weighted by how much has traded there. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.
Prices come from our regular polls of each venue, the oldest 2 min ago. Ages are as of when this page was built.

Live prediction market odds for "Will any state enact a data center moratorium by December 31?". Before Jan 1, 2028 leads at 88%. Next is Before Mar 1, 2027 at 73.5%. $79K has traded across 7 outcomes on Polymarket and Kalshi. The market is expected to resolve by Jan 1, 2027.
This market will resolve to "Yes" if any U.S. state enacts legislation that establishes a statewide moratorium on new data centers by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A qualifying moratorium must temporarily or indefinitely prohibit, suspend, or pause the approval, permitting, construction, connection to the electrical grid or other utility infrastructure, or operation of new data centers, or a defined category of new data centers, within that state. Qualifying legislation includes any state bill that establishes such a data center moratorium. Qualifying legislation must be enacted into law in accordance with the applicable state’s constitutional and legal procedures. This generally requires final passage by the relevant state legislature and approval by the governor, becoming law without signature, or taking effect through a veto override or other lawful mechanism. Legislation that does not become law under the applicable state process, including vetoed bills that do not take effect, does not qualify. The primary resolution sources for this market will be official state legislative trackers, governor’s office announcements, secretary of state records, and other official information from the relevant state government; however, a consensus of credible reporting may also be used.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
