CarbonCopy

CarbonCopy, which brands itself Carbon Copy on its own site, is a browser-based copy trading terminal built for Polymarket. A trader logs into a dashboard organized around Traders, Portfolio, Wiretap and Markets tabs, then follows wallets the platform has already scored rather than searching Polymarket's own leaderboard by hand. The homepage streams a live feed of executions being mirrored into follower wallets, market by market, as they happen.

The selection layer is the product: CarbonCopy scores candidate wallets on win rate, return, volume, consistency and a risk-adjusted measure rather than raw profit alone, and flags wallets it judges to be wash trading or running on negative expected value. Positions are copied into the trader's own wallet rather than a pooled account, matching the non-custodial design the operator advertises, and the profile carries Polymarket's own verification mark.

A trader connects a wallet rather than depositing into CarbonCopy itself; the operator describes the design as non-custodial, meaning capital stays in the trader's own wallet rather than moving into a house account before it reaches Polymarket. Once a wallet is picked from the scored trader list, CarbonCopy watches that wallet's activity and submits matching orders into Polymarket's own order book on the trader's behalf.

Before an order goes out, three guardrails sit between the signal and the fill: a position limit caps how much a single trade can expose, a drawdown guard can cut off a copy target after a losing stretch, and a filter is meant to screen out illiquid markets where a mirrored trade could get stuck. None of these change what happens on Polymarket itself; they only decide whether CarbonCopy places the order at all.

The platform also exposes an MCP server so a connected AI assistant, such as Claude Code, ChatGPT, Perplexity, Gemini or Grok, can query a trader's positions or profit and loss and follow a trader through natural-language commands instead of the web dashboard.

• Per-trade position limits

  Caps how much a single mirrored trade can expose the follower's wallet to, so one signal from a copy target cannot swallow an outsized share of the account.

• Automatic drawdown guards

  Cuts a copy target off after a losing stretch instead of waiting for the trader to notice and unfollow manually, capping how far one bad run compounds.

• Illiquid market filters

  Screens candidate trades for markets it judges too thin to exit cleanly, aiming to keep a mirrored position from getting stuck once it is opened.

• Six-axis trader scoring

  Ranks candidate wallets on win rate, return, volume, consistency and a risk-adjusted measure rather than return alone, and flags accounts it judges to be wash trading.

• MCP server for AI agents

  Lets a connected assistant such as Claude Code or ChatGPT query positions and profit and loss, or follow a trader, through natural-language commands instead of the dashboard.

Small-account copy traders

Average fills here sit at $11, retail-sized rather than desk-scale, fitting someone mirroring modest positions instead of sizing large trades.

Traders wary of custodial risk

The non-custodial design keeps funds in the trader's own wallet, which matters most to someone who has been burned by a pooled-fund platform before.

Developers building trading agents

The MCP server lets a coding agent query positions and follow traders programmatically, useful for anyone scripting a strategy around Polymarket activity.

Traders building new positions

With 85.5% of routed volume opening rather than closing positions, the tool suits someone building fresh exposure more than someone routing exits through it.

Funds stay in the trader's own wallet rather than moving into CarbonCopy's custody, so the platform is not a place capital can be frozen or lost if the company itself runs into trouble. Its profile on Polymarket carries the platform's own verification mark, which is a distinct check from anything CarbonCopy states about its own scoring or sybil detection. Using it still means granting a wallet permission to execute mirrored trades automatically, and delegating the position limit and drawdown decisions that would otherwise be the trader's own call to make fill by fill.

• What is CarbonCopy?

  CarbonCopy, styled Carbon Copy on its own site, is a non-custodial copy trading terminal for Polymarket that scores wallets on more than raw return and mirrors their trades into a follower's own wallet automatically.

• Is CarbonCopy safe to use?

  It does not custody funds, since trades execute from the trader's own wallet, but its sybil-resistance and wash-trading checks are described only in marketing terms, so the underlying method cannot be inspected.

• What does CarbonCopy charge?

  The operator publishes no fee schedule on its site or in its feature comparison table, so there is nothing to quote here; check the app's own terms before connecting a wallet.

• How does CarbonCopy pick which traders to copy?

  It scores candidate wallets on win rate, return, volume, consistency and a risk-adjusted measure, then flags accounts it judges to show wash trading or negative expected value, rather than ranking by return alone.

• Does CarbonCopy hold my funds?

  No. The operator describes the design as non-custodial, meaning capital stays in the trader's own wallet rather than moving into a pooled account before an order reaches Polymarket.

• What are alternatives to CarbonCopy for copy trading on Polymarket?

  Other copy trading and order-routing builders operate on Polymarket with their own attributed volume and rank; compare #114, $170 and fee disclosure directly against any alternative before choosing.

• Can I use CarbonCopy with an AI assistant?

  Yes. It runs an MCP server that lets assistants such as Claude Code, ChatGPT, Perplexity, Gemini or Grok query positions, profit and loss, or follow a trader through natural-language commands.
