Investing in risky ventures isn’t typically Alan Cole’s cup of tea. The self-proclaimed “normal, conventional Wall Street Journal-reading adult” (1) generally sticks to a traditional brokerage account. But when Elon Musk’s Department of Government Efficiency (DOGE) kicked off its operations in Washington last year, Cole spotted an opportunity.
In the growing arena of prediction markets, people bet the world’s richest man would succeed in shrinking U.S. government spending. But as the Wall Street Journal reports, Cole, a tax economist, understood government spending better than most and decided to take the opposite position.

Cole put all $342,195.63 of his life savings into a position he didn’t see as a gamble at all: If federal spending in all four quarters of 2025 outpaced spending in Q4 2024, he’d win big. Cole didn’t take the position lightly; in addition to his own knowledge, he spoke with several fiscal policy experts and budget analysts, as well as his wife, before making the bet.
All in, Cole walked away with $470,300 — a profit of more than $128,000 — which is about a 37% increase from his original bet. While he’ll pay taxes on his winnings, that profit is a tidy sum. As Cole proved, betting on prediction markets can be lucrative, but it’s important to understand the dangers of chasing big wins on such a platform.
What are prediction markets?
Prediction markets are essentially stock exchanges for real-world outcomes. Instead of buying shares in a company, you’re buying a contract that pays out if a specific event happens — or, in Cole’s case, doesn’t happen. Polymarket and Kalshi are popular prediction markets right now.
Kalshi, the platform Cole used, is one of the largest regulated prediction markets in the U.S. It received federal approval (2) from the Commodity Futures Trading Commission (CFTC) to operate legally. Users can place bets on everything from what Kristi Noem will say in an oversight hearing to Texas Senate election results to, yes, government spending levels.
Recently, prediction markets have exploded in popularity. Kalshi reported over $23 billion in trading volume in 2025 (3), up dramatically from prior years, driven in part by interest around the presidential election and later policy drama under the new administration.
Part of the appeal is that the more people trade on an outcome, the more accurately the price tends to reflect the real odds. Cole’s edge wasn’t insider information—he simply understood federal budget mechanics better than the people betting against him.
However, not every bet has that kind of clarity. Many prediction market wagers are closer to sports gambling, where you’re competing against sharp bettors who have as much or more information than you. Others involve outcomes that are completely unpredictable, no matter how well-informed you are, such as what MrBeast will say in his next YouTube video (4).

What to know before placing a bet
While Cole’s story has a happy ending, this isn’t an approach that everyday investors should look to replicate. He won big because he identified a rare situation: a bet that was based on information he knew wasn’t accurate. If you’re considering investing in the predictions market, here are a few things to keep in mind:
Make sure you understand what you’re actually betting on
Cole’s wager was built on hard economic data: federal spending figures that get published on a regular schedule. But many prediction market bets aren’t so clean. Read the fine print on how a contract is settled and what metrics decide who wins before placing a bet.

Don’t bet more than you can afford to lose
Prediction markets aren’t FDIC-insured and can be highly volatile. Putting your entire life savings into any single position, no matter how confident you are, is a massive risk if something goes sideways.
Factor in taxes and opportunity cost
Cole noted he’ll owe capital-gains taxes on money he moved from investments to fund the bet, and he missed out on stock market gains during that period. A 37% gross return sounds great, but the net win is lower once you account for those costs.
If prediction markets interest you, treat them the way you’d treat any high-risk, high-reward asset. Keep exposure small, understand exactly what you’re buying, and make sure a total loss won’t derail your long-term financial plan.
Cole’s bet worked, but it’s not a repeatable strategy for most casual investors.
