Recession Odds: How Prediction Markets Price a Downturn

TL;DR

• Recession odds on prediction markets are the price of a Yes contract on whether a recession happens by a set date, and the price is the market's implied probability.
• The word "recession" does not mean one thing. Some contracts resolve on the NBER's judgment, which comes months after the fact, and some on the Bureau of Economic Analysis's GDP data, so the same economy can resolve differently.
• Polymarket's "US recession by end of 2026?" market names the BEA's GDP page as its resolution source, and BEA's third-quarter advance estimate is due October 29.
• Compare recession prices across platforms and read the contract's definition before you quote one. Check the prediction market data behind the number, too, since these markets can be thin.

Wondering what the recession odds are right now? A prediction market turns that question into a price, but the number only means something once you know which definition of recession the contract uses.

This guide covers how markets define a recession, what Polymarket and Kalshi show, which data releases move the price, and how to read one.

What Do Recession Odds Measure?

Recession odds measure the chance that a recession happens by a set date, as priced by traders. Each outcome trades between $0 and $1, and the price is the market's implied probability. A Yes at $0.20 means the market gives a recession a 20% chance.

The date and the definition both matter. A contract for "a recession by the end of 2026" and one for "a recession by the end of 2027" are different contracts, and either can resolve on a different test.

Polymarket lists a market for a recession by the end of 2026 and another for the end of 2027. Right now the 2026 market puts a recession at 6.5%, and the 2027 market puts it at 32%+1.

How Do Prediction Markets Define a Recession?

There are two common tests, and they are not the same.

The first is the NBER's. The National Bureau of Economic Research describes a recession as "a significant decline in economic activity that is spread across the economy and lasts more than a few months." Its committee dates recessions after the fact, and it often announces a peak several months after it occurs.

The second is a GDP test, usually two consecutive quarters of negative real GDP growth as reported by the Bureau of Economic Analysis. That is a common shortcut. It is not the NBER's definition, and the NBER's page does not mention it.

Polymarket's "US recession by end of 2026?" market names the BEA's GDP page as its resolution source. As summarized in search results, its rules count two consecutive quarters of negative GDP or an NBER recession announcement, whichever comes first. Read the live rules before you rely on that description.

A contract that waits on the NBER can take months to settle after the economy turns. One that uses GDP settles when the data is published, and the BEA revises its estimates, so how a contract treats revisions matters. Our guide to how to read the rules covers what to look for.

What Do Polymarket Recession Odds Show?

Polymarket recession odds show one crowd's view of a very specific question. Polymarket opened its "US recession by end of 2026?" market on September 29, 2025, and it had about $2.4 million in total volume when I checked on October 26, 2026.

That is cumulative trading, not money riding on the outcome today, and it is modest next to the biggest election markets. Thin markets can move on a single position, which our guide to liquidity explains.

Polymarket also lists related markets, including negative GDP growth in 2026 and the timing of the next recession. If you want the narrowest possible read, those can sit closer to the data than a broad recession contract does.

What Do Kalshi Recession Odds Show?

Kalshi is a CFTC-regulated exchange, and it lists recession markets of its own, each with its own written terms. Right now its 2026 recession market puts a recession at 2%.

A gap between Kalshi and Polymarket is normal. It does not mean one platform is wrong. Each venue has its own traders and its own settlement terms, and a different definition can explain the gap by itself. Our piece on why odds disagree covers the rest.

Opinion is built around macro contracts, so its board is worth a look. Limitless and Predict.Fun round out the five platforms PredictionHero tracks, and each runs its own board.

What Data Moves Recession Odds?

GDP releases move the price most directly. The BEA schedules the third-quarter 2026 advance estimate for October 29 at 8:30 a.m., the second estimate for November 25 and the third for December 23. Each later estimate can change the picture.

Other data matters too. The Fed meets October 27 to 28, and our guide to fed rate cut odds explains how to read that contract. Inflation prints feed in as well, and our guide to CPI contracts covers how those are structured.

Nothing here is a forecast. It is a calendar of the releases a recession contract is likely to react to.

How Should You Read Recession Odds?

Run through five checks, in this order.

1. The definition. Is it NBER, a GDP test or both? This changes what the price means.
2. The deadline. "By the end of 2026" and "by the end of 2027" are different contracts. Check the end date, since listings can show more than one.
3. Revisions. The BEA revises its estimates. See how the contract treats later revisions.
4. Depth. Check volume and spread alongside the last trade. A thin market is closer to a few opinions than a consensus.
5. A second platform. One venue can lag. Two venues that agree are harder to dismiss.

PredictionHero lines up prediction market data from all five platforms on one screen, so you can see where the recession price disagrees without opening five tabs.
