Today, all eyes are on the U.S. election. Though the outcome is still unknown, one thing is certain: the
crypto space has already come out on top. This isn’t just due to Donald Trump’s enthusiastic
endorsements or Kamala Harris’s reserved nod to the industry. Equally noteworthy is the rising interest
in the Web3 prediction platform Polymarket.
In October, the platform hit a record-breaking $2.5 billion in trading volume. The first five days of
November added another $577 million (source: Dune Analytics). While the U.S. election has undeniably
fueled activity, Polymarket’s own popularity has soared. Since the 2020 election, the trade volume has
risen 47-fold, while monthly active traders surged from 2,000 to over 214,000 — a 107-fold increase.

Decentralized prediction markets have become a compelling real-world application for blockchain. They
provide cost-effective, globally accessible, and round-the-clock trading. This edge enabled Polymarket
to outperform traditional centralized prediction markets not just in theory, but also in practice. Yet,
it is not without controversy, facing challenges such as uncertain legal standing in the U.S. and
allegations of wash trading.
Polymarket beats TradFi alternatives
Polymarket is a Web3 platform where users can buy and sell shares in the probability of real-world
events, from election outcomes to sports scores. Its user base leans heavily into the crypto community,
as shown by a distinct skew toward pro-Trump bets. While the TradFi (traditional finance) platforms like
Kalshi, PredictIt, or Interactive Brokers show 57%, 55%, and 58% probabilities for Trump on election
day, Polymarket gives the former president a 62% chance.

Known for its venturesome spirit, the crypto community is likely contributing to Polymarket's success.
The platform now outperforms its well-established TradFi alternatives. The Trump-Harris presidential
election bet has attracted $235 million on Kalshi and $44 million on PredictIt, per their websites.
Interactive Brokers’ ForecastTrader platform does not disclose cumulative bet amounts but reported a
daily volume of $28 million on November 4th. Polymarket, by contrast, has recorded nearly $3.2 billion
in all-time bets, with $100 million traded on November 4 alone.
The disparity between these platforms is huge. Polymarket’s strong crypto community certainly plays a
role, but it is likely that at least some of its new users have opened their first crypto wallets
specifically to bet on the platform. This is a promising sign for broader crypto adoption.
How Polymarket works
Polymarket is built on Polygon, an Ethereum layer-2 solution enabling faster and cheaper transactions.
Its smart contracts automate transaction execution, ensuring security and transparency. All
betting-related data can be easily accessed on the blockchain.
Unlike traditional betting platforms, Polymarket doesn’t act as the “house” or take positions against
its users. This eliminates concerns over the potential misuse of insider knowledge. Instead, it
functions as a peer-to-peer (P2P) marketplace where prices are set by supply and demand. Prices on
Polymarket reflect collective probabilities, shifting dynamically as users buy and sell shares. All
trades are conducted in USDC, a stablecoin pegged to the U.S. dollar.
To resolve contracts, Polymarket leverages the UMA protocol that determines the outcome of events. Built
on Ethereum, UMA (Universal Market Access) is a decentralized oracle. It verifies off-chain data via an
incentive-based on-chain voting system. Once an event's outcome is confirmed, Polymarket's smart
contracts will pay the winners.
Polymarket’s decentralized nature gives users complete control over their funds via self-custodial
wallets. This means that the platform itself does not access or hold users’ private funds. It also makes
Polymarket globally accessible, except for the United States. After facing a $1.4 million fine from the
Commodity Futures Trading Commission (CFTC) for offering event-based contracts, Polymarket had to scale
back its U.S. services.
Controversies around Polymarket
Last month, Polymarket faced scrutiny over a "whale" trader who reportedly boosted Donald Trump’s odds
on the platform. The user bet $28.6 million on the former president from four different accounts.
However, the platform’s spokesperson stated that the user was “taking a directional position based on
personal views of the election” rather than trying to influence public opinion.
Also, a recent Fortune article reported that analysts from blockchain firms Chaos Labs and Inca Digital
found signs of wash trading on Polymarket. Wash trading is a form of market manipulation where shares
are repeatedly bought and sold to inflate trading volume. Both traditional finance and its crypto
alternative ban this practice for its potential to mislead about real demand. The analysts claimed the
prediction platform's actual volume was only $1.75 billion, not the $2.7 billion reported by Polymarket
at that time.
Polymarket’s representative responded by emphasizing the platform’s transparency: “Unlike on Wall
Street, Polymarket makes all transactions on its platform transparent and publicly available, including
to researchers.” Moreover, the platform "expressly prohibits market manipulation."
Some X users speculate that this high-frequency trading may relate to “airdrop farming,” where users aim
to qualify for potential token giveaways through frequent trades. The absence of trading fees (users pay
only a small amount to liquidity providers) may encourage this behavior. Indeed, while Polymarket does
not have its own token, speculations around such a possibility persist. Issuing a token could help the
platform increase activity, draw new users, and reward its existing community.
A major unresolved issue for Polymarket is U.S. compliance. Despite adding former CFTC chair J.
Christopher Giancarlo to its advisory board in 2022, the platform is still restricted in the country.
However, with both Trump and Harris signaling openness to a more favorable regulatory stance on crypto,
Polymarket may yet gain a way to operate in this crucial market.
Every election reflects shifting societal and economic trends, and in 2024, the rise of crypto is
undeniably one of them. Regardless of who wins the White House, the next administration will be expected
to adopt a clear and unbiased approach to the crypto industry.
