Why an Election Prediction Market Can Stay Open After the News Calls the Race

TL;DR

• A prediction market contract stays open until its written resolution source triggers, not until a network calls the race, a gap that can run days or weeks past election night.
• Most election contracts anchor to official government certification, not a media consensus, because certification is auditable while a "consensus" call has to be defined precisely or it becomes a judgment call after the fact.
• A recount changes when a contract resolves, not what it pays out. A Yes contract still pays $1 and a No contract still pays $0, based on the same criteria written before the race started.
• Concession is the least reliable trigger of the three: a contested candidate has no legal obligation to concede, so a contract anchored only to concession can sit open indefinitely.

Checked a prediction market the morning after election night and found the contract still open, even though every network had already called the race? You're not looking at a stale market. You're looking at one that's still waiting on its own rules, not on a headline.

A prediction market resolves on its written resolution criteria, not on a network's projection. When a race heads to a recount, a certification delay, or a contested result, the contract stays open until the specific event those rules name actually happens. That can run days or weeks past the moment CNN or the AP puts a check mark next to a candidate's name.

That gap confuses people every cycle. It's not a bug. It's the entire point of writing a contract instead of trusting a headline.

What Does "Resolution Criteria" Actually Mean?

Every event contract in a prediction market is bound to a resolution source, written into the market before a single contract trades. This is the sentence that says exactly what has to happen, and according to whom, for a Yes or No to pay out. "Will Candidate X win the election" is not a resolution source. "Will Candidate X be certified as the winner by [named authority] by [date]" is.

The resolution source is what separates a prediction market from a betting pool on a news alert. A Yes contract pays $1 if the named condition is met, and $0 if it isn't, no matter what a chyron said three weeks earlier.

How Do Platforms Actually Define a Race as "Resolved"?

Not every platform anchors to the same trigger, and that's where the confusion about timing comes from.

Official certification. The contract resolves when the relevant government body, a secretary of state, a state election board, Congress in the case of a presidential race, formally certifies the result. Certification deadlines vary sharply by state: 41 states set a hard cutoff, either a fixed number of days after the election or a specific calendar date, while Pennsylvania and Rhode Island set no state-level deadline at all. Those deadlines routinely run past the day a winner seems obvious to everyone watching.

More than 20 states and Washington, D.C. trigger an automatic recount when the margin falls under a set threshold, most commonly 0.5 percentage points. A recount under that trigger extends the resolution timeline further. A contract anchored to certification will not move until that paperwork clears, even if every media outlet already called it weeks earlier.

Media consensus call. Some markets resolve when a defined set of major outlets, the networks and wire services that traditionally call races, converge on declaring a winner. This is faster. It's also softer, because "consensus" has to be defined precisely in the rules (how many outlets, which ones, what happens if they split) or the market operator ends up making a judgment call after the fact, which is exactly the ambiguity a good contract is written to avoid.

Concession. A small number of contracts resolve on a candidate's formal concession. This is the least reliable anchor of the three. Concessions are optional, not legally required, and a candidate contesting a result in court has every incentive to withhold one. A market that leans on concession as its sole trigger can sit open indefinitely if the losing side simply never says the words.

The mismatch between these three triggers is precisely why a market can appear to lag a news call by days. It usually isn't lagging. It's tracking a different, more specific event.

Why Does Precise Resolution Language Serve the Reader, Not Just the Trader?

A contract with fuzzy criteria, like "Will Candidate X win," invites disputes the moment a race gets close. It has to be interpreted after the fact by whoever runs the market, which reintroduces the exact judgment call the market was supposed to remove.

Naming the certifying authority, the date, and the specific action required removes that interpretation before the race even starts. Precision here is a feature, not paperwork.

Say a state has a mandatory recount at a 0.5 percentage point margin, the most common threshold nationally. A contract anchored to certification will simply hold until that recount finishes and the state certifies, regardless of how the count looked on election night.

Journalists and analysts checking a market mid-recount should look at one thing first: the resolution source, not the current price. A contract sitting at 92% Yes with certification still weeks out is not indecisive. It's pricing a high-confidence outcome against a resolution date that hasn't arrived yet. Those are two different pieces of information, and conflating them is the most common misreading of a contested-election market.

How Do the Five Platforms Handle a Contested Race Differently?

The structural difference that matters most here is regulatory status. Kalshi's contracts fall under CFTC oversight, which pushes it toward the more rigid, verifiable standard of official certification rather than a media call. That's a direct trade of speed for auditability. Traders who want a faster resolution accept a contract anchored to a media consensus; traders who want a resolution that can survive a legal challenge want one anchored to certification.

Polymarket writes its election contracts on a case-by-case basis, and the specific resolution source is published on the market page itself, not assumed. That distinction matters more now that Polymarket runs two separate products: the original global exchange, still geoblocked for US persons, and Polymarket US, a CFTC-regulated exchange that opened to US traders in 2026. See our guide to Polymarket in the US for how the two now differ, and compare the resolution language on a close race across both before trading it: https://polymarket.com/?via=prediction-hero-6xku.

Predict.Fun, built on BNB Chain, structures its event contracts the same way, defined per market rather than by a blanket house rule. Check the rules field before assuming a Yes or No answers "who won" versus "who was certified": https://predict.fun?ref=3F185.

Limitless runs on-chain with its own resolution language spelled out per contract, which matters most on faster-moving down-ballot races where certification timelines vary widely by state: https://limitless.exchange/?r=X2HFDVCYMU.

Opinion, built primarily for macro and policy events, applies the same per-contract discipline to the election markets it lists, typically anchoring to official results rather than a media call: https://app.opinion.trade?code=9fFvXX.

As of 2026-08-29, PredictionHero tracks $116.7 billion in total volume and 332,550 markets across 33,140 events on these five platforms, with 4,150 of those events priced on more than one platform at once. That overlap is exactly what makes a resolution-source mismatch visible in the first place: two platforms pricing the same race can show different confidence levels simply because one has already priced in a resolution date the other hasn't reached yet.

What Should You Check in a Contract Before a Contested Race?

Three things are worth checking before a close race, not after.

1. The exact resolution source named in the contract (which authority, which date, which action).
2. What happens under the rules if a recount is triggered or certification is delayed past the market's original end date.
3. Whether the contract has a stated fallback if the primary source becomes unavailable (a contested certification, a court injunction, a state missing its own deadline).

A market that has already answered all three in writing, before the polls even close, is the one worth trusting when the count gets close.

Where Should You Go From Here?

Comparing a contract's exact resolution language, not just its current price, is the fastest way to know what a market is actually waiting on. Explore live event contract pricing and resolution rules across all five platforms on PredictionHero.
