It started as a niche corner of the internet, a financial curiosity where academics could bet on presidential elections and political junkies could put a few dollars on the Oscars. But over the last two years, prediction markets—primarily Kalshi and Polymarket—have exploded into a multi-billion dollar force, threatening to eat the lunch of traditional sportsbooks and, in the process, ignite a political firestorm.
If 2025 was the year prediction markets burst into the mainstream, 2026 is shaping up to be the year they face their existential reckoning. From federal lawsuits and bipartisan congressional bills to crackdowns by state attorneys general, the walls are closing in. Here is the truth behind the backlash, why it’s happening right now, and how it could completely reshape the way you think about betting online.
What Are Prediction Markets, Really?
Before we dive into the drama, let’s level-set. Prediction markets allow users to trade “event contracts” based on the outcome of real-world happenings. Will the Federal Reserve raise interest rates? Will it rain in New York next Tuesday? Who will win the Super Bowl?
For decades, the Commodity Futures Trading Commission (CFTC) has overseen these markets, viewing them not as gambling, but as financial derivatives that help people hedge risk and aggregate information. Platforms like Kalshi argue they are the same as trading oil futures or betting on the price of gold—except the “asset” is an event.
But in 2025, the dam broke. Kalshi launched a feature called “Combos,” allowing users to place peer-to-peer parlay bets on sports. Suddenly, the lines between a CFTC-regulated exchange and a state-regulated sportsbook like FanDuel or DraftKings vanished entirely.
Today, sports markets account for roughly 90% of weekend trading volume on Kalshi. During the 2026 Super Bowl alone, trading volume on Kalshi surpassed $1 billion. Traditional sportsbooks, which pay massive state taxes (sometimes as high as 51%) and spend millions on compliance, saw the writing on the wall. They are competing against a “gray market” with lower overhead, zero state taxes, and far fewer consumer protections.
The Great State vs. Federal Smackdown
The most explosive headline of April 2026 came from the Department of Justice. In an unprecedented move, the Trump administration filed federal lawsuits against three states—Arizona, Connecticut, and Illinois—to block them from regulating prediction market operators.
The states have been fighting back hard. Arizona even filed criminal charges against Kalshi, accusing the company of operating an illegal gambling business and allowing bets on elections. Nevada gaming regulators have also managed to push cases back to state court, putting Kalshi and Polymarket at risk of being shut down in the gambling capital of the world.
CFTC Chairman Michael Selig, backed by the White House, is playing hardball. “The CFTC will continue to safeguard its exclusive regulatory authority over these markets and defend market participants against overzealous state regulators,” Selig said in a statement last week, warning against a “fragmented patchwork” of state-by-state rules.
It’s a fascinating legal battle: States rights vs. Federal authority. The CFTC argues that event contracts are “swaps” under the Commodity Exchange Act, and federal law preempts state gambling statutes. The states argue that when you put money on the Bears vs. the Packers, it’s gambling—plain and simple.
The Bipartisan Hammer: “The Prediction Markets Are Gambling Act”
While the CFTC and states battle it out in the courts, Congress is sharpening its own axe. On March 23, 2026, a bipartisan coalition led by Senator Adam Schiff (D-CA) and Senator John Curtis (R-UT) introduced the “Prediction Markets Are Gambling Act.” This isn’t a niche partisan squabble—it’s a unified strike.
If passed, this bill would strip the CFTC of its authority to oversee sports-related contracts. It would effectively ban Kalshi, Polymarket, and any other federally regulated exchange from offering wagers on athletic events or casino-style games.
“We cannot allow a federal agency to greenlight a nationwide gambling industry that bypasses the laws of our states and the sovereignty of our tribes,” Schiff argued during the bill’s introduction. Senator Curtis echoed the sentiment, calling prediction markets a “legal fiction” designed to skirt local gambling prohibitions.
The market reaction was immediate and brutal. Shares of Flutter Entertainment (FanDuel’s parent company) and DraftKings jumped nearly 10% following the announcement, as investors bet that the elimination of this low-overhead competition would be a massive win for the regulated incumbents.
Insider Trading, “Death Markets,” and the Sleaze Factor
Beyond the legal fights, prediction markets have a reputation problem. And that reputation problem is why the general public—and Google Discover—are suddenly paying attention.
This isn’t just about betting on football anymore. It has turned dark. In recent months, traders on Polymarket made massive, timely bets predicting military strikes in Iran and Venezuela. Six newly created accounts on Polymarket made more than $1 million by betting on the timing of US or Israeli strikes on Iran, leading lawmakers to call them “death markets”.
The CFTC is now investigating widespread insider trading. In one jaw-dropping case, a bettor made over $400,000 betting on the arrest of Venezuelan leader Nicolás Maduro just hours before the US military acted. Lawmakers fear that government officials or intelligence agents might be using classified information to profit on these platforms.
In response, Polymarket and Kalshi rushed to update their policies. They have banned political candidates from trading on their own campaigns and preemptively blocked athletes from trading on games they play in. They have also added new surveillance tools to catch suspicious activity.
However, critics argue these are “window dressing” measures. Former CFTC General Counsel Rob Schwartz recently warned that the entire industry could disappear with a change in administration. “It could go away in one fell swoop,” Schwartz said, noting that a Democratic president in 2028 could reverse the Trump-era green lights without much trouble.
The Tribal Casino Wild Card
There is another massive player in this fight that rarely gets headlines: Native American tribal casinos.
Tribal gambling enterprises generate more than $40 billion a year, revenue that funds healthcare, housing, and education in Native American communities. They see prediction markets as a direct existential threat to that revenue stream.
At the Indian Gaming Association’s annual convention in San Diego this year, “prediction markets” were the only thing on the agenda. Indian Gaming Association Chairman David Bean accused the platforms of misrepresenting their products to sidestep decades of carefully negotiated federal and state laws. “This is no innovation,” Bean said. “This is unlawful gambling dressed up as finance”.
The tribes have announced a defense fund to support legal actions against the platforms, adding yet another powerful lobby to the “anti-prediction market” coalition.
Will Traditional Sportsbooks Win or Join Them?
You might think FanDuel and DraftKings are celebrating the backlash. And to some extent, they are—their stock prices surged when the “Prediction Markets Are Gambling Act” was introduced.
But the reality is more complicated. The horse has already bolted from the barn. The mechanics of prediction markets (lower fees, better tax treatment for high-volume traders, no “house” banning winners) are simply superior to the traditional sportsbook model for many bettors.
In fact, both DraftKings and FanDuel have already launched their own “prediction-style” products to compete. Dave Mazza, CEO of Roundhill Investments (which runs a sports betting ETF), notes that the incumbents are evolving rather than being displaced. “Regulation will determine how fast this converges, but it’s not a zero-sum game,” Mazza said.
If the federal government wins its lawsuits against Arizona and Illinois, prediction markets could open up in all 50 states overnight. If the states win, we will revert to a “patchwork” of regulations that heavily favor the established, tax-paying sportsbooks.
What Does This Mean for the Average Bettor?
For the average user sitting at home with a smartphone, the stakes are high.
Scenario A: The Crackdown Succeeds.
If the “Prediction Markets Are Gambling Act” passes and the states win their court battles, Kalshi and Polymarket will likely be forced to exit the sports betting vertical. You will lose access to the low-fee, exchange-style trading environment and go back to traditional sportsbooks where the house holds the edge and “winning players” often get their accounts limited or shut down.
Scenario B: The CFTC Wins.
If the Trump administration successfully defends federal preemption, prediction markets could explode in growth. Eilers & Krejcik predicts the US prediction market industry could reach a staggering $1 trillion in volume when fully mature. Citizens Bank estimates annual industry revenue could hit $10 billion by 2030.
This would democratize betting, allow for institutional money to flow into event trading, and likely force traditional sportsbooks to lower their margins to compete.
Why This Story Matters Right Now
We are watching a David and Goliath story play out in real-time. On one side, you have the Old Guard: State gaming commissions, tribal casinos, and legacy sportsbooks who spent billions to secure exclusive licenses and high tax rates.
On the other side, you have the Disruptors: Kalshi, Polymarket, and a CFTC chairman who believes that trading on the Super Bowl should be treated the same as trading on pork belly futures.
This isn’t just a legal debate. It touches on national security (insider trading on wars), consumer protection (age verification and addiction controls), and the very nature of what we consider “gambling.”
The next 12 months will be decisive. As one analyst put it, 2026 is “the year governments and regulators begin to react in earnest”. We are watching the birth pangs of an entirely new asset class—or the swift execution of a regulatory loophole.
The Bottom Line
Prediction markets face a perfect storm of opposition: a bipartisan Congress, hostile state attorneys general, powerful tribal casino lobbies, and a scandal-ridden reputation due to insider trading.
However, they also have a Trump-appointed CFTC chairman willing to sue sovereign states to protect them, a Robinhood integration that puts event trading in the hands of millions, and an economic model that is arguably fairer to the user than traditional sportsbooks.
Whether you love them or hate them, the outcome of this backlash will determine how millions of Americans engage with sports, politics, and finance for the next decade. Stay tuned—this year, the betting landscape might look entirely different by the time the NFL playoffs roll around.
