The largest crypto prediction market, settled on Polygon via UMA optimistic oracle. CLOB-style order book hosted on the Polymarket gateway with sub-second publish latency for live odds.
StandX is a DUSD-margined perpetuals DEX on BNB Chain (13 markets in 2026-09: majors plus gold, silver, oil and a few equities) with a public market-overview endpoint carrying volume, open interest and hourly funding per market.
Funding is signed. Positive means longs pay shorts, negative means longs get paid to hold. Venues settle on different native periods (hourly on Hyperliquid, dYdX, Lighter, Extended, Pacifica, Ondo, Vest, StandX and ApeX, every 4h on edgeX, every 8h on Kalshi, Aster and the CEX books); every figure is normalized from the venue's own quoted rate and interval before ranking. Funding is only the holding cost. Opening costs (taker fee, spread, impact) are the companion bench perp-fees.
Ranked only with 24 hours of funding history (288 samples) and a stddev above zero: a young listing, or a venue whose rate has not moved since listing (Ondo Perps at launch, Polymarket in July), reads artificially stable and shows as Provisional, never as the leader. Stability is not directionality: a persistently positive but tight band ranks above a rate that flips every settlement.
The ratio is a screen, not a verdict. Both terms are the venue's own
figures (24h volume and open interest as each API reports them, in USD),
so a venue that counts both legs of a fill moves its ratio without
changing anything real. A very low ratio (Ostium, 0.2x) means positions
held for days on thin daily volume; a very high one (Kalshi, above 40x)
means a day of trading dwarfs what stays open. The bands in the
methodology say what each range usually means.
Every row is a month of funding at the venue's average daily cost over
the hours measured in the trailing 30 days (average x 30). A venue
ranks only with 576 of the 720 hours (24 days) behind that average;
under the floor the row is provisional, unranked, and shows its day
count (the venues added on 2026-09-22 and 2026-09-23 start there).
Funding is signed: on a month where shorts paid longs the figure is
negative and "cheapest" means "was paid the most".

How is the Polymarket vs StandX comparison measured?
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing; panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
