Market Making on Polymarket: Why Maker Status Cuts Loss Probability by 36 Points — and Why Spreads Persist Anyway

Akey et al.'s most economically significant finding: moving from pure taker to pure maker status reduces the probability of losing money by ~36 percentage points on Polymarket. Resolution-spec risk is why cross-platform spreads persist at 1.5–4.5% and why even Susquehanna and Jump can't fully arb them.

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
