People are betting on wildfires on Polymarket. What could go wrong?

The 2026 wildfire season on the West Coast is shaping up to be an especially bad one: In Oregon, more than 2 million acres have already burned, breaking a record set just a few years ago, in 2024. In neighboring Washington state, suburbs around the city of Spokane recently burned in an increasingly common example of fires reaching urban and suburban areas (as my colleague Caitlin Dewey covered recently). And the consequences are spreading far beyond where the fires are burning, with hazardous smoke from the Pacific Northwest drifting as far away as New England

Much of this is a story about climate change, as increasingly dry, hot summers provide ample fuel for fires. But the crisis is also being made worse by the Trump administration: Staff cuts to the US Forest Service have left the agency stretched thin and unable to respond as effectively to fires, while a planned reorganization is also set to shutter Forest Service labs researching and tracking wildfires. EPA research into wildfires and wildfire smoke has also been slashed. 

All of this — plus a Trump administration shift away from letting some fires burn themselves out, which has further increased the workload on wildland firefighters — has also resulted in a more dangerous fire season for firefighters; Reuters reported this week that firefighters are “being overrun by wildfires at the highest rate in two decades” — with months still to go until the end of the season.

Go a little deeper

As if the above weren’t enough to worry about, lawmakers are also raising a brand-new fire season concern: prediction markets. Specifically, the possibility that bettors could turn to arson in order to manipulate prediction markets — and earn themselves some money. 

Polymarket, on its international platform, has offered users the chance to bet on everything from when and where a fire might spread to when it could be contained or extinguished, which resulted in more than $1 million in bets on major fires in California last year. High Country News reported in June that a new prediction market, called Wyldfyre, had launched specifically for betting on wildfires.

Legislators like Sen. Jeff Merkley (D-OR) have pointed out that, unlike most other natural disasters, fires are easily started or spread by humans, creating a real risk that people could attempt to manipulate markets. 

“Offering bets on destructive wildfires threatens to minimize communities’ suffering all so the rich and powerful can profit,” Merkley and eight other Democratic senators wrote in a letter to the head of the Commodity Futures Trading Commission last week. “There’s also the heightened risk—according to state and local fire officials—that individuals could be tempted to commit arson in order to make sure their bets are successful. By offering contracts on fires, prediction market sites run the risk of encouraging people to influence fires that have already started, creating additional concerns around public safety and insider trading.

Why Trump is tearing up a beloved national park

Welcome to The Logoff: Remember President Donald Trump’s first-term border wall? It’s still being built — through a pristine Texas national park.

What’s happening? The Trump administration is preparing to build hundreds of miles of roads through Big Bend National Park in southwest Texas as part of its latest border security project, despite a bipartisan outcry over damage to the beloved park. 

Starting last week, bulldozers and heavy machinery began to clear land for the construction of about 200 miles of patrol road, new border barriers, and electronic surveillance measures to cover the park’s 118 miles of shared border with Mexico. The construction is proceeding after the administration overrode environmental laws intended to protect places like Big Bend earlier this year.

What does a border wall look like in 2026? In this case, “wall” is a bit of a misnomer. Despite Trump’s fixation with an actual, physical wall circa 2016, the Trump administration’s current project isn’t always 30 feet high and topped with concertina wire.

Instead, the Big Bend project is part of what the administration has described as a “smart wall,” which will combine stretches of traditional wall elsewhere along the US-Mexico border with patrol roads and vehicle barriers like those planned for the park, all blanketed with surveillance. 

It’s a small retreat from the administration’s original plan for a border wall through Big Bend, which sparked outrage earlier this year. Still, the administration intends to build about 700 additional miles of “primary” wall, spanning all four border states. The whole project is slated to cost around $47 billion. 

Why Big Bend? It’s hard to say. As the New York Times reported earlier this year, the park has long been considered low-priority given its remote location and inhospitable weather. Only about 1 percent of those apprehended for crossing the US-Mexico border have been detained in Big Bend.
