Stan

Stan is a Polymarket builder, an app that submits trades to Polymarket's order book under its own builder code so the exchange can attribute the flow separately from ordinary retail trading. Polymarket lists it with a verified profile, though our own categorization has not been able to place it into a defined vertical, so it sits filed as other or unknown pending clearer public information about what the underlying product actually does.

By the numbers, Stan has attracted $28.8M in all-time attributed volume, good for #28 among the builders our index tracks. The trailing week shows $50K across 2.8K fills, spread over a cohort of 158 wallets averaging 23 distinct traders a day. Flow since 2026-04-29 has leaned heavily toward up-or-down contracts, with Solana Up or Down - August 30, 8:15PM-8:30PM ET standing out as the single busiest market in the past thirty days.

Placing a trade through Stan tags the order with the builder's own code before it reaches Polymarket's central limit order book, which is how the exchange can credit the fill to Stan rather than to organic retail flow. The matching itself happens on Polymarket's infrastructure, not inside Stan, so the tool's job is limited to originating and labeling the order rather than executing it.

Settlement follows Polymarket's own architecture: positions and collateral sit in the trader's wallet on Polygon rather than in an account controlled by the builder, since attribution through a builder code does not require the tool to hold funds. What Stan does with an order before submission and what confirmation a trader receives are details the operator does not publish, so a trader should treat those steps as unverified until stated directly.

That omission matters more as size grows. A cohort of 158 wallets moving $82K over the past thirty days is small enough that a single large account could dominate the average fill of $350, so a trader evaluating Stan should watch whether 23 distinct daily traders looks like a genuine crowd or a handful of repeat accounts before assuming the flow is broad-based.

• Short-dated crypto focus

  Recent flow concentrates in up-or-down contracts such as Solana Up or Down - August 30, 8:15PM-8:30PM ET, suiting traders who want fast, event-driven crypto bets rather than long-dated positions.

• Balanced entry and exit flow

  Buy share sits at 50.8% of routed volume, so the venue sees roughly as many exits as new positions rather than skewing one way.

• Retail-scale fill sizes

  Average fill runs at $350, in line with individual retail positions rather than the four-figure-plus tickets typical of desk trading.

Short-term crypto event traders

Flow concentrates in up-or-down contracts like Solana Up or Down - August 30, 8:15PM-8:30PM ET, so this fits traders chasing fast, event-driven crypto outcomes rather than long-dated bets.

Retail-sized accounts

Average fill of $350 points to smaller position sizing, so it suits traders working with individual accounts rather than desk-level capital.

Traders tracking momentum shifts

The trailing week's change, +397.9%, makes Stan worth watching for anyone tracking which builders are gaining flow week over week.

Traders who trade both sides

A buy share of 50.8% means it works about as well for closing a position as for opening one, unlike venues built mainly for entries.

Traders comparing builder volume trends

With rank #28 and $28.8M in lifetime attributed volume, Stan gives traders benchmarking builder activity another data point to weigh.

Stan's operator does not publish a fee schedule, so there is no advertised rate to compare against what a trader ends up paying. Polymarket's own trading fee is set market by market and applies equally regardless of which builder routes the order, so it does not distinguish Stan from any other builder and isn't a reason to choose or avoid it. What a trader should confirm before committing size is whether Stan layers any additional charge, spread, or rebate arrangement on top of that baseline, since nothing in the available record states one either way. Absent that confirmation, treat the true cost of routing through Stan as unknown rather than assume it matches the baseline.

• Polymarket verifies Stan's profile, which at least confirms the builder code is tied to a claimed identity rather than an anonymous one.
• Volume has accelerated sharply over the trailing week, shown in +397.9%, rather than a builder that's gone quiet.
• A buy share near 50.8% shows traders route both entries and exits through it rather than using it one way only.
• An average fill of $350 keeps it accessible to retail-sized accounts rather than requiring desk-level capital.
• Flow has run for 139 days without interruption, which is enough time to rule out a one-week fluke.

• The operator publishes no fee schedule, leaving the true cost of routing through it unstated.
• Its curated category sits as other or unknown, so even basic classification of what the product does is missing.
• At 139 days since its first fill, it hasn't been tested across a full market cycle yet.
• A cohort of 158 wallets is small enough that a handful of accounts could be driving most of the flow.
• Concentration in up-or-down contracts like Solana Up or Down - August 30, 8:15PM-8:30PM ET means the flow is narrow rather than spread across market types.

Custody follows Polymarket's own model: funds and positions live in the trader's wallet on Polygon, not with the builder, so routing through Stan doesn't hand the operator control of anyone's balance. Its Polymarket profile carries verification, which at least ties the builder code to a claimed identity rather than an anonymous one. Transparency stops there. Stan discloses no fee schedule and no public description of its own product, so a trader is relying entirely on Polymarket's attribution data rather than anything the operator states. With a cohort of 158 wallets and 23 traders a day, the flow is thin enough that a trader should treat any single week's numbers as provisional rather than a settled track record.

Stan is worth a look for traders who want exposure to fast-moving crypto up-or-down markets and don't mind that the operator hasn't published a fee schedule or a clear description of what the product actually is beyond routing flow. The trailing week's jump captured in +397.9% shows real momentum, but a cohort of 158 wallets and 139 days of history is thin enough that the pattern could shift quickly. Traders who need fee certainty upfront, or who trade markets outside short-dated crypto contracts, are better served elsewhere until Stan discloses more about its own terms.

• What are alternatives to Stan?

  Any Polymarket builder ranked near #28 on attributed volume makes a reasonable comparison point; check each one's own fee disclosure and cohort size before choosing where to route.
