The public case for prediction markets rests on a category claim: these are financial instruments that price risk, not wagers that manufacture it. Polymarket’s contracts on whether named American banks will fail are the cleanest available test of that claim, because the event being priced is not a game or an election but the collapse of an insured institution. Bloomberg’s Andrew Ackerman and Katanga Johnson report that when the contracts were raised at an internal meeting, officials inside the Federal Deposit Insurance Corporation asked two questions that the category claim cannot answer: whether the contracts carry any legitimate commercial or investment benefit, and whether the agency’s ethics rules were strong enough to stop its own staff from trading on them.
The scale is small, and it is worth stating plainly rather than inflating. Wagers on individual bank failures total just a few hundred dollars in many cases, with contracts on firms like Deutsche Bank and Wells Fargo running into the thousands. The set tied to failures before the end of this year has drawn $76,000 in total volume; an earlier set keyed to failures by July saw $591,000. This is not a market capable of moving a bank today. It is a market establishing a product line.
Where the contracts live
The detail that carries the most weight is jurisdictional. Polymarket’s CFTC-regulated US exchange, which serves American customers, does not offer wagers on bank failures. Those contracts sit on the older international platform — offshore, outside the CFTC’s supervision, and closed to US traders by the company’s own terms. The distance between the two venues is a compliance boundary, not a difference in the product. The company’s chief legal officer, Neal Kumar, defends the markets on the familiar grounds: bank bailouts and failures are among the most consequential events in America, and the platform aggregates information that would otherwise be available only to sophisticated financial institutions. Supporters add that the low probabilities on these contracts demonstrate their value as a real-time check on panic and online rumour.
The regulatory problem is that the same market can be both. A binary contract on a bank’s survival gives a customer a direct way to take a position on a collapse without borrowing shares or buying credit default swaps — a cheaper and faster expression of the same view, and one that produces a public price. Sheila Bair, who ran the FDIC during the 2008 crisis, does not accept the information argument: the contracts, she told Bloomberg, encourage bad actors to weaponise social media, stoke rumours and deliberately trigger panic. “I don’t see any socially beneficial value with those kinds of contracts to offset the financial stability threats and the risks that they pose.”
The agency’s own information
The second question officials raised is the more uncomfortable one, because the FDIC does not merely insure the deposits at issue — it keeps a confidential list of problem banks, and it takes failing lenders into receivership. Senior staff discussed whether the agency’s existing ethics restrictions needed revising to prohibit employees from trading on Polymarket, and concluded the current rules were sufficient. No change followed. Chairman Travis Hill had already said at a private event in March that prediction markets could be a useful monitoring tool while worrying aloud about people speculating on the timing of bank failures.
That the question had to be asked is the finding. An agency supervising thousands of small banks, holding non-public supervisory judgements about which of them are in trouble, now has to reason about whether its staff can trade contracts whose resolution it is positioned to anticipate.
The same business, different line
Capitol Hill’s reaction splits along the expected lines. Senator Elizabeth Warren, the ranking Democrat on the Senate Banking Committee, called the contracts reckless and described the oversight regime as “the wild west, full of insider manipulation” — commentary about the regulators, not a finding about these specific markets. Kalshi, which is CFTC-regulated and Polymarket’s principal competitor, does not offer contracts on individual bank failures; its spokesperson called Polymarket’s “in poor taste,” which is a useful reminder that the industry’s line between acceptable and unacceptable event contracts is a commercial judgement rather than a principle.
The insider-trading record is not hypothetical. In April the Justice Department accused a US soldier of using classified information to make more than $400,000 on Polymarket’s international exchange, which authorities say he reached through a VPN. The company says it referred the trading to authorities; the defendant has pleaded not guilty and has asked a judge to dismiss the case as overzealous. Both Kalshi and Polymarket say they oppose insider trading, police their markets and pass tips to law enforcement.
Bank-failure contracts are a rounding error inside a multibillion-dollar prediction-market business in which sports wagers dominate and the jurisdictional fight over state gambling laws is being litigated circuit by circuit. But they are the part of the business where the “gambling or finance” argument stops doing any work — where the product is a wager on a named institution’s failure, the best-informed potential traders are the people who supervise it, and the cost of being wrong lands on depositors and on the stability of the thing being priced.
