Polymarket’s most active market over the weekend centered on a Russian election whose outcome carried little uncertainty, drawing significant trading volume despite near-unanimous expectations about the result.
The contract, which asked users to bet on the winner of a regional or national vote widely expected to favor the incumbent , traded heavily even as prices implied a probability close to 100% for the eventual victor. Activity surged into the final hours before resolution, with traders continuing to buy shares priced at $0.98–$0.99 that would settle at $1 if the expected outcome materialized.
The pattern underscores a recurring dynamic in prediction markets: high trading volumes are not always driven by disagreement or informational edge, but can instead emerge around events where outcomes are effectively predetermined.
While traditional financial markets tend to see liquidity concentrate where uncertainty is highest, prediction markets often attract participation in “certainty trades,” where participants are effectively earning small spreads on outcomes perceived as inevitable.
Volume Concentrates Around Near-Certain Outcomes
Data from the market shows that the vast majority of trades were executed on the favored outcome side, with minimal liquidity on alternative results. Bid-ask spreads frequently compressed to one or two cents, and in some cases disappeared entirely, reflecting strong consensus among participants.
Such conditions create an environment where traders are not expressing differing views on probability, but instead competing to capture marginal returns by repeatedly buying and holding contracts close to their final settlement value.
In theory, a contract priced at $0.99 offers a 1% return if it settles at $1. In practice, however, fees, slippage and execution risk can erode much of that margin. The persistence of volume in these conditions suggests that participants may be using automated strategies, market-making systems or capital rotation approaches rather than discretionary directional bets.
The phenomenon has parallels with short-term crypto event markets, including intraday Bitcoin contracts, where trading activity can cluster around narrow price bands with limited informational content.
Critics argue that such markets risk overstating genuine user engagement. High notional volumes may give the impression of active price discovery, even when the underlying trades are effectively low-risk, low-return positioning around a widely accepted outcome.
Prediction Markets Blur Line Between Trading and Yield
The Russian election contract also highlights how prediction markets increasingly function as hybrid instruments combining elements of betting, trading and yield generation.
For some participants, buying near-certain outcomes resembles a fixed-income strategy, where capital is deployed to earn small, short-duration returns. For others, the activity may be part of broader portfolio management, including hedging or liquidity provision.
Polymarket, which operates on blockchain infrastructure using stablecoin-denominated contracts, has seen growing participation across political, economic and crypto-linked markets. Its rise has been fueled in part by the ability to offer real-time, tradeable probabilities on a wide range of events.
However, markets tied to politically sensitive or tightly controlled elections introduce additional considerations. In cases where outcomes are widely perceived as predetermined, the informational value of price signals diminishes, even as trading activity increases.
The weekend’s activity therefore reflects a broader structural question for prediction markets.
Are they primarily tools for aggregating information and forecasting uncertain outcomes, or are they evolving into platforms where capital seeks short-term, low-risk returns regardless of informational content?
The answer may lie in the data itself. When the busiest market is one with virtually no disagreement about the result, volume alone becomes an incomplete measure of market quality.
As prediction markets continue to expand into new geographies and event types, distinguishing between meaningful price discovery and mechanical trading activity will remain central to how these platforms are interpreted by participants, regulators and observers alike.
