PredictFolio

What it is

A free web dashboard that reads Polymarket's public record and lays out one wallet at a time: trading volume, current portfolio size, markets traded and net profit and loss, with a chart over a month, the year to date, a year or the whole history. You can look up any address or Polymarket username. Nobody has to own the wallet to read it, which makes it trader analytics as much as a portfolio tracker.

A trader page, read on 30 September 2026, carries:

• A P&L chart drawn with TradingView's charting library, with a mark-to-market setting that values open positions at the current price and adds realised results.
• Positions, combos, closed positions and activity. Combos are Polymarket's combined positions, which PredictFolio says its own on-chain indexer, Auspex, now accounts for so that P&L on a combined market matches what is held.
• A P&L calendar, day by day or month by month.
• Wins and losses counted by market, and a "genre mix" showing what share of a wallet's markets were sports, esports, crypto, politics and so on.
• A profile score out of 100. No method for it is published anywhere we could find.
• Several wallets on one chart, and a comparison between them.

Two features are about your own money rather than somebody else's.

Import P&L history. Add Kalshi's export, or any other venue's, to the chart beside your Polymarket line, or sum it into one figure. It is the only way a second venue gets onto the page. The importer checks the file: a Kalshi export whose rows do not add up gets a warning, and the chart then uses the file's own P&L columns anyway.

Tax report, in beta. A yearly transaction report for each verified wallet, with realised P&L and fees, downloadable as a PDF or a CSV. The sample on the home page shows individual buys, sells and redemptions as dated rows. The report is behind a login, and the pages we could reach do not say how a wallet is verified, which cost-basis method is used, or which country's tax rules the figures follow.

Availability

Nothing to deposit and nothing to trade, so the questions that decide a venue card do not apply. The terms set out no geographic restriction, no age gate and no identity check. Trader pages and market pages open without an account. An account, by email and password or through Discord, is only asked for at the tax report.

What the site cannot do is make Polymarket available to you. A US reader can read every page here, but Polymarket's international venue does not serve them. Polymarket US is a separate venue, and nothing on these pages says its accounts are covered.

Terms of service and privacy policy, both last updated 29 October 2025, read on 30 September 2026.

Pricing

Free. The terms of service describe the service as "a free-to-use analytics tool", the footer repeats it, and there is no pricing page, no plan table and no paid tier anywhere on the site. The /pricing path answers with the site's "trader not found" page.

That covers the tax report too: nothing on the site asks for payment for it. It is labelled beta, and a free beta can gain a price later. The terms promise 30 days' notice of a material change, with the operator deciding what counts as material.

Markets & resolution

PredictFolio lists no markets, takes no trades and resolves nothing. Each market, price and outcome belongs to Polymarket, whose process decides the result, and PredictFolio reads the on-chain record. The subjects follow whatever Polymarket lists: politics, sports, economics, crypto, culture and company events.

The numbers on a trader page are derived, not reported by the venue. The terms say the data comes from public blockchain sources and carries no warranty of accuracy or completeness. A realised P&L figure depends on how a sale is matched to a purchase, and a win count depends on what counts as a market. PredictFolio publishes neither rule.

Integrations

None published. There is no API, no SDK, no webhook and no MCP server, and the terms forbid robots, spiders and other automated access without written permission. The site's data can leave only through the tax report's PDF and CSV. Kalshi or another venue's exports can come in through the importer.

Limitations

A tax report is not a tax filing. Neither the report nor the site names a jurisdiction, a form or a cost-basis method. A US reader needs Form 8949 rows and a method the IRS accepts. A reader elsewhere needs whatever their own authority asks for. A yearly list of realised P&L and fees is the raw material for either one, and it has to be checked against the wallet's own history. The feature is labelled beta, and the terms disclaim the accuracy of every number on the site.

Polymarket only. Kalshi and other venues appear only as files you import. There is no second live source, and nothing compares a question across venues.

The scores are unexplained. The profile score out of 100 and the win and loss counts come with no published method. A wallet's page is an account with a record, not a named person. One trader can run several wallets, and a wallet can be a bot.

Two company names. The footer credits PredictFolio B.V. The terms and privacy policy, the documents that bind you, name ClearCode B.V. in Amstelveen as the provider and data controller. The terms' governing-law clause names only "the jurisdiction in which PredictFolio operates".

Alternatives

For a Polymarket tax report built for a US filing, PolyTaxes produces Form 8949 rows and a TurboTax CSV from a public wallet, for a price per tax year.

For wallet and trader analytics without the tax angle, Polymarket Analytics has a paid tier and an API, Predicts.guru has wallet lookups and leaderboards with no registration, and PolyWallet tracks wallets read-only with mark-to-market P&L and a CSV export.
