The Truth Machine: How Polymarket and Kalshi Turn the Midterms Into a Casino

The world of political forecasting has been turned upside down. As the US midterms approach this Tuesday, strategists are no longer just looking at the numbers from established institutes. Online prediction markets like Polymarket and Kalshi have long since taken the lead. Here, people aren't asked who they want to vote for; instead, they put cold hard cash on the actual outcome. According to the operators, this financial incentive is supposed to strip away social masks and reflect the true expectations of the masses. In Washington, a genuine casino atmosphere has taken hold, where even government officials discuss market odds over after-work drinks.

The rise of these platforms is rapid. Polymarket founder Shayne Coplan confidently calls his product a truth machine. The logic behind it is as simple as it is compelling: those who put money down are less likely to lie. In traditional surveys, there is often social pressure to hide certain preferences. On the betting market, only profit matters, which according to Coplan leads to higher accuracy. However, reality is more complicated, as recent failures in Brazil showed where the market was completely wrong. Nevertheless, sums are flowing into the sector that were previously unthinkable, blurring the line between political participation and pure gambling.

Numbers and facts

The dimensions are gargantuan. According to the Anti Corruption Data Collective, more than $220 million has already been bet on the midterms. This is more than double the entire 2024 election cycle. Kalshi goes even further, speaking of a total of over $1 billion that has flowed into the betting pots. A look at the odds reveals the extreme confidence of the gamblers: on Polymarket, a victory for the opposition in the House of Representatives is traded with a probability of 93 percent. The Senate stands at 68 percent for the Democrats. In Texas, James Talarico is seen ahead with 69 percent, while Abdul El-Sayed reaches 72 percent in Michigan. For comparison, $11 million is currently in the pot for the question of Senate majority on Polymarket alone.

But where there is big money, fraud is often not far behind. Reports of insider trading are piling up. A US soldier allegedly won $400,000 because he had advance knowledge of plans to kidnap Venezuelan leader Nicolas Maduro. There were also incidents within Donald Trump's circle. A teleprompter operator was penalized for betting on the exact wording of presidential speeches. Polymarket itself stated it had investigated dozens of bets for manipulation. Despite these dark sides, the influence is hard to stop, as even platforms like RealClearPolitics now integrate betting odds into their reporting.

Background

The history of prediction markets as political indicators gained momentum two years ago. While pollsters predicted a close race between the parties, Polymarket and Kalshi foresaw a clear victory for Donald Trump. They were right. This gave them enormous credibility, which is now being monetized in the current election period. The platforms even receive prominent support from the former president's family: Donald Trump Jr. serves as a consultant for both companies. This strengthens political networking but simultaneously raises questions about the independence of such markets when actors with a direct line to the White House are involved.

"The best way to be informed about the course of our elections is not to give a few the floor. It is rather to let the market speak. It is about letting the people speak. And that is exactly what prediction markets provide." - Tarek Mansour, CEO of Kalshi

Why it matters for German players

For players in Germany, the situation is clear but sobering. Platforms like Polymarket or Kalshi do not possess a license from the Joint Gambling Authority of the States (GGL). According to the State Treaty on Gambling 2021, bets on political events are generally not permitted in Germany. Anyone trying to bet on the US midterms from Berlin or Munich is engaging in illegal gambling. German licenses cover only sports betting and virtual slot games, which are subject to strict rules. These include a cross-provider deposit limit of 1,000 euros per month and a stake limit of one euro per round for slots. These protective measures provided by LUGAS (Cross-State Gambling Supervision System) are completely absent from US prediction markets.

What it means for GGL-licensed casinos

Legal German providers look at the billion-dollar turnovers across the Atlantic with a mixture of envy and skepticism. While the GGL whitelist meticulously prescribes which betting markets are allowed, Polymarket and others operate in a regulatory gray area that attracts massive volumes. For German operators, this means they must clearly demonstrate in their marketing why their controlled offers are safer. Player protection and manipulation prevention are guaranteed in Germany through state supervision, while US markets struggle with insider scandals. Nevertheless, the trend shows that interest in event betting is growing massively, which could increase pressure on German regulators in the long run to carefully expand the betting catalog.
