Polymarket Market-Making Bot
We build prediction-market quoting software around your eligible markets, inventory policy and execution requirements. Market discovery, pricing, order validation and fill reconciliation are separate components. Scope and acceptance tests are agreed before development; access remains subject to platform rules and applicable restrictions.
Priced for your scope. A short description is enough to start.
What's included
- CLOB two-sided quoting
- Inventory skew & exposure limits
- Resolution-aware widen / flatten
- Live PnL & inventory tracking
Best fit for
- Prediction-market MM
- Liquidity provision
- Spread capture
Custom Polymarket market-making software
Prediction-market automation needs more than a loop that posts a bid and an ask. The software must know which outcome token it is trading, whether the market is eligible, what inventory is already held and which orders remain outstanding. We define those requirements before implementing a quoting policy.
This service is for commissioning software around your own execution rules. It is not an investment offering or a promise that a spread, rebate or reward will produce a profit. We can build a standalone component, extend an existing application or scope a complete backend and operational interface.
Market selection and order validation
The market-discovery component maintains the identifiers and metadata required by the selected integration. Your eligibility rules can restrict categories, liquidity conditions and time to the relevant market deadlines. The implementation checks current order constraints rather than assuming that every market accepts the same prices and sizes.
Account setup and signing are designed for the agreed platform and account model. The current Polymarket developer documentation is the implementation reference; exact endpoints, fee assumptions and supported workflows are confirmed during discovery. We do not implement bypasses for geographic or account-access restrictions.
Inventory-aware quoting and execution
Quoting rules specify reference prices, spreads, order sizes and inventory adjustments. Exposure calculations include filled inventory and outstanding orders. If a fill arrives while an order is being cancelled, the system must reconcile the resulting state rather than assume cancellation removed the exposure.
Market closure, resolution and settlement are distinct lifecycle events. The proposal defines how each event affects quoting, cancellation, inventory reporting and any separately commissioned position-management workflow. No automatic exit is assumed to be possible at a specific price.
Tests and handover
Acceptance scenarios can include partial fills, stale market data, changes to order constraints, a rejected cancellation, an unavailable API and process restart. Tests should show the resulting account state and recorded decisions, not just successful HTTP responses.
The agreed delivery can include source code, configuration, test fixtures, deployment instructions and order/fill logs. A custom dashboard, historical simulation, multi-account support and maintenance are optional scope items. Development, infrastructure and platform costs are identified separately in the estimate.
See our Polymarket market-making requirements guide for planning details. If your workflow follows another wallet rather than maintaining quotes, Polymarket copy trading development is a different service.
Describe your Polymarket project with target markets, quoting rules, inventory limits and existing software. You do not need a finished specification or production credentials to request an individual proposal.
Technical scope
What we design and verify
A production polymarket market-making bot is more than a working demo. Each major component below is scoped around the target network or platform, expected load, failure conditions and the way your team will operate it after handover.
CLOB two-sided quoting
This part of Polymarket Market-Making Bot is specified as a separate, testable component with acceptance criteria, logging and documented configuration rather than hidden hard-coded behavior.
Inventory skew & exposure limits
Controls are enforced in code before an action is submitted. Thresholds remain configurable, while rejected actions and triggered safeguards are recorded for later review.
Resolution-aware widen / flatten
This part of Polymarket Market-Making Bot is specified as a separate, testable component with acceptance criteria, logging and documented configuration rather than hidden hard-coded behavior.
Live PnL & inventory tracking
Operational visibility is part of the delivered system: health, important actions, failures and relevant business metrics are exposed without placing private keys in the interface.
Definition of done
Before delivery, we validate the agreed happy path, expected failures and operational controls. You receive the applicable source code, configuration reference, deployment instructions and a walkthrough of the system. Any third-party fees, infrastructure subscriptions or external dependencies are identified during scoping.
Delivery
How the engagement works
Technical discovery
We confirm the objective, constraints, integrations and acceptance criteria.
Architecture & scope
You receive milestones, responsibilities, timeline and the final quote.
Build & verification
Implementation is tested against the agreed scenarios with visible progress.
Handover & support
We deploy or hand over the code, documentation and operating instructions.
Built for production
Scope, security and ownership
Delivery model
Market discovery, order-book data and execution workflows are designed as observable, replaceable components.
Security baseline
Allowance scope, wallet permissions, order checks and explicit risk limits stay under client control.
What we need from you
Market selection rules, execution requirements, budget limits and the accounts or infrastructure you already use.
Questions before you start
How is Polymarket Market-Making Bot priced?+
We quote each project after discussing the required features, integrations and deployment. Send a short description; a finished specification is not required. We agree the scope, milestones and price before work begins.
How long does delivery take?+
Timing depends on integrations, testing depth and whether existing code is involved. After a short technical discovery, we provide milestones and a delivery estimate before payment.
Who controls the source code, infrastructure and keys?+
The agreed source code and deployment are handed over to the client. Production wallets, seed phrases and private keys remain client-controlled; we design integrations around scoped credentials and least-privilege access.
Do you guarantee trading profits or a specific return?+
No. We build software and execution infrastructure, not guaranteed-return products. Results depend on strategy, competition, liquidity, fees and market conditions. Testing, simulation and explicit risk controls should precede live capital.
Can you work with our existing code or infrastructure?+
Yes. We can begin with a focused review, identify reusable components and propose the smallest safe implementation path instead of forcing a full rebuild.
