Earlier than the NYC election, roughly $368 million was traded on Polymarket’s NYC mayoral market. About 92% of contributors wagered on Mamdani successful. One dealer even positioned a $1 million guess on his victory.
The accuracy wasn’t luck. Polymarket appropriately predicted Donald Trump’s 2024 presidential victory when most polls confirmed a toss-up. The platform gave Trump round 60% odds, which turned out nearer to actuality than polls exhibiting 50-50 possibilities. Polymarket additionally appropriately predicted the end result of NYC’s Democratic major in June.
Analysis backs up these outcomes. Research evaluating prediction markets to ballot aggregators discovered that betting markets had been extra correct throughout presidential, Senate, Home, and governor races. The rationale? Folks make smarter predictions when their very own cash is at stake.
How Prediction Markets Work
Prediction markets function in another way than common playing websites. Customers purchase “sure” or “no” shares on whether or not particular occasions will occur. In the event you’re proper, you receives a commission. In the event you’re flawed, you lose your funding.
The share costs change based mostly on provide and demand, creating real-time chances. When Polymarket exhibits Trump at 60%, it means merchants collectively consider he has a 60% likelihood of successful.
These markets declare to faucet into the “knowledge of crowds.” When a lot of individuals threat their cash based mostly on evaluation, the collective prediction tends to be correct. Conventional polls ask who individuals need to win. Prediction markets ask who individuals assume will win—with monetary penalties for being flawed.

One evaluation steered wash buying and selling made up about one-third of exercise on the presidential market.
Massive bets additionally increase eyebrows. 4 merchants positioned $25 million on Trump’s 2024 victory, resulting in questions on whether or not rich people may manipulate odds. The platforms argue that when somebody bets huge on one facet, others guess in opposition to them, holding costs balanced.
Critics additionally level out that Polymarket customers may not characterize common voters. The platform requires cryptocurrency, which solely 17-20% of Individuals personal. This might create bias towards sure political beliefs.
What Mamdani’s Win Means for Crypto
Satirically, the identical prediction markets that precisely forecast Mamdani’s victory could face tighter rules below his management. The brand new mayor has been vital of cryptocurrency’s affect on working-class communities.
Mamdani co-sponsored laws searching for to halt proof-of-work crypto mining as a result of environmental issues. In 2023, he said that when crypto corporations collapse, rich traders don’t undergo—it’s small traders from low-income communities who lose cash.
His platform contains elevating taxes on companies and the rich to fund public companies. He helps proposals for a crypto transaction tax that would increase $158 million yearly. Beginning January 1, 2026, his administration is anticipated to prioritize client safety and compliance over market growth.
This creates an uncommon scenario the place crypto prediction platforms precisely predicted an consequence which will result in stricter crypto rules. President Trump had endorsed Cuomo and threatened to withhold federal funds if Mamdani received, however voters selected the democratic socialist anyway.
The Backside Line
Crypto prediction markets proceed proving their worth as forecasting instruments. Polymarket’s correct name on the NYC mayor’s race provides to a rising monitor report that features the 2024 presidential election and NYC’s Democratic major. Whereas issues about manipulation exist, the markets have constantly outperformed conventional polling.
