Analysts Say Polymarket Metrics May Be Inflated

A platform often praised for proving that crypto prediction markets can scale now faces an unexpected credibility test — not due to fraud or wash trading, but because the industry may have misread its blockchain.
Polymarket has been celebrated as one of the breakout successes of the current cycle, complete with eye-catching volume claims, billion-dollar valuations, and talk of rapid U.S. expansion. But according to Paradigm researcher Storm, the figures analysts have relied on may tell a distorted story.
- Polymarket volumes were likely double-counted.
- Major dashboards inflated its trading figures.
- Its lofty valuation metrics may be overstated.
Instead of inflating its own metrics, Storm says the fault lies with the analytics tools used to interpret Polymarket’s on-chain data — which he described as unusually layered, difficult to parse, and capable of producing misleading totals.
Two Views of One Trade — Counted as Two
The core issue stems from how Polymarket logs activity. Every matched order generates mirrored “OrderFilled” signals — one representing the maker’s view of the transaction, another for the taker. On-chain, these appear as distinct events, but in reality, they reference the exact same trade.
Dashboards that simply tally raw contract emissions have unknowingly added both sides together — turning one trade into two and inflating aggregate numbers whether analysts were tracking notional turnover or net cash flow.
Analysts Admit They Were Fooled
The revelation has ripple effects. Platforms like DefiLlama, Allium, Blockworks, and several Dune dashboards have built their charts using the flawed counting method. Paradigm says this problem didn’t emerge from negligence – Polymarket’s architecture is unusually intricate, incorporating swaps, position splitting, and merging mechanics that make conventional indexing tools unreliable.
Storm argued that even seasoned data teams struggled because “block explorers don’t reveal which signals represent true net volume versus redundant accounting entries.”
A $9 Billion Valuation With Numbers Now in Question
The problem carries weight because Polymarket’s perceived growth underpinning investor interest may shift once corrected metrics emerge. ICE recently pegged the platform’s value at $9 billion, citing $25 billion in activity — a figure Paradigm suggests could reflect double-counted flows.
Monthly records touted by analytics dashboards — such as the claimed $3.7 billion in November turnover — may also shrink once datasets are reprocessed.
A Growing Sector Facing a Maturity Test
Polymarket did not immediately comment on the findings, but the episode underscores a broader issue: prediction markets are transitioning from niche experiments to recognisable financial sectors, and sloppy measurement standards could erode confidence.
Storm concluded that the industry needs its own version of financial accounting rules — consistent definitions, transparent calculations, and a shared framework — if prediction markets want institutional capital and regulatory credibility.
