Prediction markets just had their biggest moment yet, and you can thank golf.
While most people were glued to the drama of the Masters, traders on platforms like Kalshi and Polymarket were clicking, buying, and selling at record speed. By the time the final putt dropped, the numbers told a wild story.
And that is prediction markets posted their biggest week ever in early April, with total trading volume pushing past $6.5 billion.
That is not a typo. Billion with a B.
Golf Meets Wall Street Energy
A big chunk of the trading volume came from the Masters itself, which turned into the largest sports event in prediction market history. On Kalshi alone, about $545 million was traded on Masters-related markets.
For context, that is more than many traditional betting events. It makes it the single largest sports event in the platform’s history, even outperforming the Super Bowl when you look at how concentrated the betting was.
The star of the show was the “Outright Champion” market, which hit $460 million. That means the only time people have traded more on a single topic was during the 2024 U.S. presidential election.
It turns out that watching Rory McIlroy almost blow a six-stroke lead on Saturday only to fight back on Sunday is exactly the kind of drama that prediction market traders live for.
One birdie, one bogey, and the market moved like it just had too much coffee.
Not Just About Golf
While the Masters was the star of the show, it was not the only reason numbers went through the roof.
Between political polls and some global headlines involving the U.S. and Iran, the total platform volume on Kalshi hit a record-breaking $3.4 billion for the week.
Not to be outdone, Polymarket raked in about $2.5 billion during the same stretch. A big part of that was driven by sports, but political markets are also seeing a massive 141% growth in interest.
So whether one group of users was sweating over putts at Augusta or busy trading on elections and world events, the message is pretty glaring: People would much rather trade their opinions on an exchange than just the traditional sports betting platforms.
A Trillion-Dollar Future?
If you think this week was big, some analysts believe it is just a preview.
A new report from the Wall Street broker Bernstein suggests that prediction markets could grow into a $1 trillion industry by 2030.
That is massive growth from where things stand today, but weeks like this make the idea feel a little less far-fetched.
“We expect revenue from prediction markets to grow from $150 million in 2025 to $586 million in 2026. This will account for 17% of transactional revenue and 10% of total profit in the current year, which will be rich in catalysts. The U.S. hosts the World Cup in the summer, and political activity will intensify in the second half of the year ahead of the midterm elections,” Bernstein detailed.
According to their analysts, the industry is on track to grow about 80% every year as it matures from a place for sports fans into a global “information market” used by everyone from retail traders to big institutions.
“The institutional market will grow around economic, business, and political contracts—investors need more direct and closed access to such phenomena. Additionally, corporations and insurance companies will want to hedge risks associated with specific situations,” explained Bernstein.
With the big guys like Robinhood and Coinbase already playing ball to help distribute these markets, it seems like prediction trading is well on its way to becoming a permanent fixture of the financial world.
If their math holds up, the $6 billion we saw this week will eventually look like pocket change.
