Real‑time election odds can mislead prediction‑market traders

Prediction‑market platforms such as Kalshi let users bet on election outcomes with binary contracts that pay $1 if the event occurs. While the contract price is often read as an implied probability, the price a trader actually pays can change in milliseconds as news moves other participants.

Why speed matters

On September 9, DoubleZero announced that its Edge service streams Kalshi’s order‑book data over a dedicated network. The feed delivers real‑time bids, offers and trade executions, allowing firms to react faster than users who rely on the standard WebSocket connection.

How the market works

A contract priced at $0.60 represents a 60 % implied chance, but traders must consider the spread between the best bid and best offer, the quantity available at each price, and fees. Buying 1,000 contracts at $0.60 and selling them at $0.65 would earn $50 before fees, regardless of the election result.

Impact on market makers

Market makers continuously post buy and sell quotes. If news pushes the perceived probability higher, a faster feed lets them adjust quotes before competitors’ orders are filled, reducing the risk of repeated losses. Wider spreads or reduced liquidity can result when market makers cannot keep up, making trades more expensive for retail bettors.

Benefits for ordinary users

When professional firms compete on price, they may narrow spreads and increase contract depth, which can lower costs for casual bettors who do not purchase a premium data feed. The actual benefit, however, depends on how prices and available quantities move during high‑impact political events.

Broader implications

Election odds can feed into crypto‑related investment decisions, such as assessing legislative risk for blockchain projects. Yet a more accurate political forecast does not guarantee a profitable trade if the entry price is too high.

Regulatory considerations

The CFTC has warned that insider information—such as a candidate trading on their own race—poses a separate risk from mere speed advantages. Surveillance and fast data distribution address different concerns.
