Lipstick on a Pig: Prediction Markets and the New Era of Gambling in America

Just a decade or two ago, Silicon Valley inspired images of a brighter future where technology would bring countless improvements to our daily lives and bring people together across geographic distances and cultural divides. In hindsight, the downsides are now clear. Social media algorithms are widely seen as behavioral toxins that have more often divided us rather than bringing us together. Majorities now believe that AI is an economic and even civilizational threat.

Then there are the old vices dressed up as shiny new apps. The most prominent and potentially harmful example of this is the prediction market. You can now bet on election results, interest rates, and ballgames right from your phone, on a platform engineered to look reassuringly like an investing account. The candlestick charts, the bid-ask spreads, the language of "traders" and "positions" and "price discovery" all send the same subliminal message: this isn't gambling, it's finance.

Two companies dominate the space: Kalshi and Polymarket. Both let you buy and sell contracts that pay out based on real-world outcomes and both are riding a wave of extraordinarily friendly treatment in Washington that is doing a great deal to inflate their fortunes.

How prediction markets work

The mechanics are simple. You buy a contract tied to a yes-or-no question, and it trades between zero and one dollar. A contract at 60 cents implies the crowd thinks there's about a 60% chance the answer is yes. Guess right and it pays a dollar; guess wrong and you're left with nothing.

The industry's favorite argument is that this is genuinely useful, not mere gambling. Because real money is on the line, the prices become a live, crowd-sourced forecast, and there's a real economic idea underneath that: markets aggregate information, and the resulting "price discovery" is something economists have taken seriously for decades. Fair enough. But it's worth noticing how conveniently that high-minded framing serves the business. "We're building a truth-seeking forecasting engine" is a much better story to tell regulators and reporters than "we run a betting app," even when the second description is closer to what most customers are actually doing.

Follow the volume

Whatever the theory says, the reality is written in the trading data, and the reality is sports. Once these platforms were cleared to offer sports contracts, the money flooded in, and as of early 2026 sports made up roughly 87% of Kalshi's trading volume. The elegant markets on inflation and Fed policy, the ones that get quoted in the press as evidence of the platforms' civic value, are a rounding error next to people betting on games.

That distinction matters, because the whole regulatory case for treating these companies as financial exchanges rather than casinos rests on the idea that they serve a market function. When the overwhelming majority of the activity is wagering on sports, that case starts to look less like a principle and more like a loophole.

A very lucrative friend in Washington

The growth has been staggering, and it isn't an accident. Combined monthly volume on Kalshi and Polymarket more than quadrupled in eight months, from under $5 billion in September 2025 to about $24 billion in April 2026. Investors have piled in accordingly. Kalshi's latest funding round valued it at roughly $22 billion, up from $2 billion a year earlier, an elevenfold jump in twelve months. Polymarket, backed by the parent company of the New York Stock Exchange, has been valued around $8 billion.

The single biggest reason for that run-up is political. The federal agency that oversees these markets, the Commodity Futures Trading Commission, spent years skeptical of them. Under new leadership installed in 2025, it reversed course and became one of the industry's most reliable allies. It has since gone to remarkable lengths on the industry's behalf, suing roughly nine states to stop them from applying their own gambling laws to these platforms. Read that again: a federal financial regulator is taking states to court to keep them from regulating what those states consider gambling. States haven't gone quietly; Arizona has filed criminal charges, including counts of illegal election wagering. But the current administration has largely thrown its weight behind the companies, and the companies' valuations reflect it.

Examining the fine print

The CFTC's own proposed rulebook, released in June, highlights the darker possibilities of these markets. These rules would permit most sports and event contracts but ban certain ones as too easy to manipulate, bets on individual player injuries and referee calls among them, along with contracts on assassinations, terrorism, and war. These are sensible things to prohibit. They are also a quiet admission of what this activity can become when left alone: a marketplace where someone stands to profit from a player getting hurt, a match being fixed, or worse.

The real world consequences

There is a nefarious logic behind the slick marketing and sleek user interface. A prediction-market app and a brokerage app can look nearly identical, and that resemblance is doing real financial damage.

A study published this year in the Journal of Financial Economics, built on transaction data from about 184,000 households, found that after sports betting was legalized, households cut their net investment in brokerage accounts by roughly 20%. The pain landed hardest on financially vulnerable households, which ran up credit card balances and loan payments to cover the gap. Other research has tied legalization to falling credit scores and rising bankruptcies.

One of the study's authors put it bluntly: people watch a lot of sports, feel like experts, and convince themselves they have an edge, but almost no one actually makes money over an extended period of time. The screen shows you charts and probabilities and calls you a trader, but the math is a casino's, and the house does not build a $22 billion company by losing.

The bottom line

Prediction markets are a real innovation, and as pure forecasting tools they can be genuinely impressive. They are now often more trusted than polls in their predictive value for election results and economic outcomes. None of my criticism in this article is meant to be an explicit criticism of prediction markets or gambling by people who understand the mechanics of the underlying games they’re playing.

But let’s be clear-eyed about what's being sold here. An enormous amount of money and political capital is riding on convincing you that a bet is an investment, because "investment" is the word that keeps the regulators friendly, the valuations high, and the customers coming back. But don’t get it twisted, these companies are just the latest reinvention of one of the oldest industries in the book.
