Polymarket Faces Allegations Over Inflated Trading Volumes
The cryptocurrency prediction market platform, Polymarket, has come under scrutiny following claims of double-counting trading volumes on major analytics dashboards. The controversy, sparked by research from Storm Slivkoff of Paradigm, has raised important questions about transparency in the decentralized trading world.
The Core Issue: Double-Counting Trade Events
Storm Slivkoff’s research highlights a technical flaw in Polymarket’s smart contract data. According to the allegations, the platform generates two separate OrderFilled events for each trade—the maker and the taker sides—leading to these events being aggregated incorrectly by most public dashboards. As a result, every trade is effectively counted twice, presenting an inflated volume.
For example, a single transaction of YES tokens for $4.13 was represented as two events, which were then summed to report $8.26 in trading volume. This process reportedly inflates both notional volume (the number of contracts traded) and cashflow volume (the dollar value exchanged). It’s important to note that this issue is unrelated to wash trading but stems purely from the way Polymarket’s contracts emit data.
Industry Response to the Controversy
Polymarket has responded quickly, clarifying that its official website accurately reports taker-side volumes without double-counting. The team emphasized that the issue primarily affects third-party dashboards that rely on raw, unprocessed data from the platform’s smart contracts without correcting for redundant entries.
Several prominent data providers, including DefiLlama, Allium Labs, and Blockworks, have committed to updating their dashboards to address this discrepancy. However, some dashboards had already distinguished between redundant representations of trades but had not documented their methodology before the controversy arose.
Interestingly, Paradigm—which brought the issue to light—has been criticized for its potential bias, as it invests in Polymarket’s competitor, Kalshi. This highlights the competitive dynamics within the decentralized prediction market space.
Why Accurate Metrics Matter
Accurately measuring activity on prediction market platforms like Polymarket is vital for traders, analysts, and stakeholders. Inflated metrics can mislead users and investors, particularly since traditional volume metrics may not reflect the actual capital at risk. Alternatives like open interest and fee revenue are being proposed as more reliable indicators of platform activity.
The timing of this revelation is striking, as Polymarket prepares for a full-scale U.S. relaunch following regulatory approval by the CFTC. With an anticipated valuation of $12-$15 billion and plans for an internal market-making operation, the platform faces amplified scrutiny.
Exploring Prediction Markets
For those interested in navigating decentralized prediction markets, accurate data and reputable platforms are essential. As part of your cryptocurrency journey, consider using wallets like the Ledger Nano X, a highly secure hardware wallet for storing crypto assets while engaging in trading activities.
The Bigger Picture
Ultimately, the Polymarket controversy highlights the broader challenges of data accuracy and transparency in the rapidly evolving crypto industry. As prediction markets gain traction, addressing these issues will be crucial for maintaining trust and fostering innovation.
