Kalshi jumped above 34% when oil crossed $100. Polymarket is sitting at 31%. Both platforms repriced the same macro shock in real time. Here is a full breakdown of what every active recession market is actually pricing right now and what changes the number next.
US recession probability on prediction markets as of March 12, 2026. Kalshi prices recession at 28% after peaking above 34% when WTI crude crossed $100/barrel. Polymarket recession odds sit at 31%. Both platforms moved from a 20-25% floor in January following US-Iran conflict, Strait of Hormuz closures, and Iraqi oil output falling to one-third of pre-conflict levels.
Kalshi prices a 60% chance gas exceeds $4/gallon this month. The inflation surge contract sits at 87c. April 10 CPI is the next inflection point. Fed March 18 hold near 100%. Catalyst tracker shows 4 of 6 near-term drivers push recession odds higher.
Six weeks ago, recession odds were sitting at a floor. Kalshi hit an all-time low of 25c in January after Q3 2025 GDP came in at a strong 4.3%. The soft landing was the base case. Then February 28 happened.
US-Israel strikes on Iran began. The Strait of Hormuz closed. Iraq's oil output fell to less than one-third of pre-conflict levels. WTI crude surged 13% in a single week, the fastest pace since oil futures began trading in 1983, and briefly touched $119 per barrel on March 9. That is when Kalshi crossed 34% and Polymarket hit 31%, both at their highest levels since November 2025.
The move was not panic. It was the market calculating a very specific transmission mechanism. Oil at $100-plus means gas prices follow. Gas prices following means inflation re-accelerates. Inflation re-accelerating means the Fed cannot cut. Fed cannot cut means growth slows. Growth slowing on top of an energy shock is how recessions historically start. You can track how these probabilities shift in real time on our live macro markets terminal.
RSM chief economist Joe Brusuelas has outlined the recession trigger levels: oil at $125/barrel, gas at $4.25/gallon, inflation running at 4% annually. WTI peaked near $119 before paring back. The market is not at those levels yet. But it is pricing the probability of getting there.
Kalshi's main 2026 recession market defines a recession as two consecutive quarters of negative GDP growth. That is the technical definition, different from the NBER's broader "significant decline in economic activity" standard. The current 28% after pulling from a 34% peak tells you the market partially de-risked as oil pared from $119 back to the mid-$90s. But it did not go back to 25%. The floor repriced upward.
The more telling number is the gas market. Kalshi currently prices a 60% chance US national gas prices exceed $4 per gallon this month. The national average was $3.48 as of Monday, March 10. That is a 50-cent surge from $2.98 before the war started. The market is essentially saying there is a coin-flip-plus chance we hit the first rung of the recession trigger ladder before March ends.
The Q1 recession start probability at 13% is actually useful context. Kalshi traders are not saying we are already in a recession. They are saying the risk is real but accumulates through Q2 and Q3 as the energy shock propagates through consumer spending, trucking costs, airline fares, and food prices. That is a historically accurate read of how oil shocks transmit. They take time.
Polymarket's recession contract resolves on NBER declaration OR two consecutive negative GDP quarters. The broader trigger is part of why Polymarket sits 3 points above Kalshi's current level. A slowdown that triggers the GDP definition but does not yet get an NBER stamp would resolve Polymarket's market but not Kalshi's.
Polymarket is also pricing the IMF global recession scenario separately. That market is worth watching because it captures the second-order effect: if a US energy shock slows American demand, slows Chinese manufacturing exports, and hits European energy costs simultaneously, the global recession contract starts repricing fast.
The gap between 31% recession odds and 22% negative GDP odds is the part worth sitting with. The market is saying there is a higher chance of a broadly defined downturn than a full-year GDP contraction. Translation: prediction market participants are pricing a significant slowdown, not necessarily a crash. Soft landing is gone as the base case. Hard landing is not yet the consensus. The market is pricing something in between.
The path from here is not symmetric. There are more near-term catalysts that push odds higher than catalysts that pull them back down. Here is what the markets are watching.
The Fed is the most trapped it has been in years. An oil shock raises inflation while simultaneously threatening growth. That is a stagflationary setup that removes the ability to cut rates in response to weakness. The March 18 hold is near-certain. But the statement language will matter. If Powell signals concern about the inflation re-acceleration without acknowledging the growth risk, recession odds reprice higher immediately.
April 10 is the CPI print that matters. Every number in the February report was collected before the Iran strikes began on February 28. March is the first data that captures the energy shock in full. The April 10 print will show whether the transmission mechanism is already running hot. That is when recession odds either settle back down or start a second leg higher.
The inflation surge contract on Kalshi sits at 87c. That is real money pricing near-certainty that inflation re-accelerates in 2026. Watch that number alongside the recession market. If 87c holds through the April 10 print, recession odds above 30% become the new floor, not a peak.
Both platforms repriced the same shock in the same direction within 48 hours of each other using completely different infrastructure and user bases. That convergence is the signal. When Kalshi's regulated US order book and Polymarket's global on-chain market land on the same read, the probability is not noise.
28 to 31% is not a prediction that a recession is coming. It is the market saying the risk is real, the floor has moved up, and the April 10 CPI print is the next inflection point. Between now and then, watch the gas price market at 60% and the inflation surge contract at 87c. Those are the leading indicators. The recession number follows them.
The soft landing consensus that was priced in January is gone. What comes next depends on whether oil holds above $100 and whether the energy shock has enough time to show up in the March data. Prediction markets will price that story in real time before any sellside note gets written. That is the edge this data gives you.
