I’ve mostly just been following my intuition, building as I go, and trying to look at everything from the user’s side — what would actually be better for them.

One thing led to another, and here we are.

@web3_sumon @SSRN Opened the research repo behind The Friction Ledger.

Inspect it, check the arithmetic, and tell me where it breaks😊

Published my first paper on SSRN.

I analyzed 1.34M Polymarket BUY-side fills across 439 settled markets. In this sample, modeled fees were 10.4× the gross trading edge. @SSRN https://t.co/WI4bIjhL7C

Prediction-market fee curves do something strange: they make uncertainty expensive and near-certainty volume cheap.

I tested a one-parameter fix — add a floor, keep static revenue neutral, and make the result falsifiable.

6/6 A prediction is not a trade until its price and costs are specified.

1/6 A small gross edge. A fee bill 10.4× larger.

I reconciled $419.4M of Polymarket BUY-side flow: +0.143% before modelled fees, −1.345% after.

1.34M fills. 439 settled markets. Dec 2025–Aug 2026. All BUY fills treated as takers.

[Ailin Sun @ailinsunX]

5/6 Limits are part of the result:

Top 500 active markets; newest 6,000 fills per market. Unsettled markets excluded. All-BUY-as-taker fee assumption.

Frozen aggregates let you check arithmetic. They do not reproduce the raw-tape analysis.
