Concentrated Volume Across Assets
Data from Kalshi's public API reveals that perpetual futures volume on the exchange is heavily concentrated in a small number of repeating trade sizes. On ether perpetuals, a single $5,499 trade size accounts for 57% of sampled volume, according to analysis by CoinDesk. Bitcoin perpetuals show a similar pattern: recurring $2,500 and $5,000 trade sizes together made up 54% of sampled bitcoin-perpetual volume in the same period.
Kalshi's Explanation
Kalshi said in response that the volume concentration reflects its incentive programs, which are filed publicly. The exchange did not provide additional detail on the structure of those programs or how they mechanically drive traders toward specific order sizes. Neither The Defiant nor CoinDesk reported confirmation of the incentive program mechanics from independent sources.
Market Context
The concentration of volume into discrete, repeating trade sizes is unusual for mature derivatives exchanges, where volume typically spreads across a broader distribution of order sizes. Kalshi, a CFTC-regulated exchange, has grown its perpetual futures offerings as part of an effort to compete with larger platforms like Deribit and Bybit. The degree to which volume reflects genuine trading demand versus incentive-driven activity remains unclear.
Why It Matters
For Traders
Concentrated volume in specific sizes may create slippage divergence depending on order placement; confirm execution quality against your target size before routing orders to Kalshi perps.
For Investors
Volume concentration driven primarily by incentives rather than organic demand signals limited organic liquidity depth and suggests market structure remains fragile relative to larger venues.
For Builders
If you are integrating Kalshi order flow or liquidity, validate that depth metrics account for incentive-driven clustering to avoid overestimating true market depth.
