Prediction markets recorded unprecedented trading volume in recent months as contracts tied to the presidential election and other political events attracted a new class of participants, including quantitative traders and asset managers treating the platforms as legitimate sources of market intelligence.

Two venues dominate the space: Polymarket, a blockchain-based platform operating outside direct U.S. regulatory oversight, and Kalshi, a CFTC-regulated exchange based in New York. Both reported record activity, but their structural differences have created distinct user bases and trading behaviors.

Polymarket processed more than $3 billion in total volume across political contracts during the election cycle, according to publicly available blockchain data. The platform operates using cryptocurrency and is technically restricted to non-U.S. users, though enforcement of that restriction has been uneven. Its contracts settle based on crowd-sourced resolution mechanisms, with disputes adjudicated by token holders.

Kalshi, by contrast, holds a Designated Contract Market license from the Commodity Futures Trading Commission, making it the only federally regulated prediction market exchange in the United States. The platform launched election contracts in 2023 after a protracted legal battle with the CFTC, which initially sought to block political betting on public interest grounds. A federal appeals court ruled in Kalshi's favor last year, opening the door to regulated event contracts.

"The regulatory clarity matters more than people realize," said a quantitative trader at a market-making firm active on both platforms. "On Kalshi, we know exactly how contracts settle, what the margin requirements are, and that we're not going to wake up to the platform being inaccessible. That's worth something when you're putting real size on."

Institutional Adoption

The distinction has practical implications. Institutional participants, including hedge funds and proprietary trading desks, have gravitated toward Kalshi for larger positions, viewing the CFTC oversight as essential for compliance and risk management. Polymarket, meanwhile, has attracted retail traders and crypto-native participants comfortable with decentralized infrastructure.

Both platforms have drawn attention from political strategists and media organizations, which increasingly reference prediction market odds alongside traditional polling data. The real-time nature of the markets and their ability to incorporate new information rapidly have made them useful barometers, even for participants who do not trade.

"These are becoming legitimate price-discovery mechanisms," said a portfolio manager at a U.S. pension fund who monitors but does not trade on the platforms. "When a debate happens or news breaks, you see reaction in these markets faster than you see it anywhere else. That's valuable information."

The CFTC has signaled continued scrutiny of the sector. A spokesperson for the Commission declined to comment on specific platforms but noted that the agency "remains focused on ensuring that markets under its jurisdiction operate with integrity and transparency."

As election-related contracts near expiration, attention is shifting to whether the platforms can sustain activity beyond political events. Both have introduced contracts on economic data releases, corporate earnings, and other financial outcomes, testing whether the infrastructure built for election betting can support a broader marketplace for event-driven speculation.
