Unusual Predictions

What it is

Wallet and flow analytics for Polymarket, sold by Unusual Whales, the options-flow company. It is the product that was Hashdive. Unusual Whales announced the product on 8 January 2026 and said Hashdive is now part of the company. The old hashdive.com pages for the screener, trader analysis, smart scores and whale trades now answer with a permanent redirect to the new product, checked on 30 September 2026. Its API sits under a path named after Hashdive. The bare hashdive.com address still serves the old app's shell, titled "Polymarket Analytics by Hashdive", but none of its pages we tried survived the move. One product, renamed: this card is both.

The product reads every Polymarket trade and sorts wallets and fills into four screens:

• Smart money. Every wallet scored by Hashdive's Smart Score, from -100 to 100, per category: crypto, culture, finance, politics, sports, weather and others. The vendor says the score combines return on investment, effective trade count, win rate, edge and position sizing. A wallet counts as "smart" above 10 with at least 10 markets. The top-traders table (score, win rate, markets, P&L, amount invested, with a filter to include or exclude bots) opened on 30 September 2026 without signing in.
• Smart gap. Where the smart-scored wallets are positioned against everybody else in a market, drawn as two distributions.
• Whales. Large positions with entry price against current price and running P&L, and an alert when a large holder takes the side the market prices as unlikely.
• Potential insiders. A Z-score ranking of accounts that are new, concentrated in one outcome, and early relative to the news.

Watchlists tie these together, with alerts when a flagged wallet or a watched market moves.

Availability

This product holds no money and places no orders, so who may deposit and who may trade have nothing to attach to. Unusual Whales' terms of service set out no geographic restriction and no identity check. You need an account to subscribe, and a card to pay. The terms carry a "Last updated" date of 15 June 2021, and nothing in them is written about prediction markets. The product is governed by a document written for an options-data service five years ago.

Seeing a flag and being able to trade the market behind it are separate questions. Polymarket's international venue does not serve US persons, so a US subscriber gets the whole feed and no way to act on it there. Polymarket US is a separate venue, and nothing here says its flow is covered.

Terms of service and pricing pages read on 30 September 2026.

Pricing

Free: a daily market summary, a basic market overview, "limited whale trade alerts, a taste of the full feed", and community access.

Unusual Predictions, 20 USD a month month-to-month, or 17 USD a month billed as 204 USD a year. The plan lists full potential-insider alerts, smart-money tracking across every market and every whale-trade notification. The API page says your key arrives with the subscription and its rate limits are the Predictions plan's.

Bundled. The Unusual Whales stock-and-options plans (Retail Basic at 50 USD a month, Retail Pro at 75 USD, Retail Max at 120 USD, month-to-month) each list Unusual Predictions in their contents. A reader who already pays for options flow has this. A reader who wants only this should buy the 20 USD plan and nothing else.

All sales are final. The terms say so, and the pricing page repeats it: you can cancel future renewals, not get money back. The pricing page adds that a wrong product can be swapped within 7 days.

Markets & resolution

Nothing is listed, traded or resolved here. Every market, price and outcome is Polymarket's, and Polymarket's own process decides it. What this product adds is a reading of who holds what, and since when.

Every screen is built on derived labels, and none of them is a fact about the world:

• "Smart money" is a score computed from past P&L. A wallet that was right in politics last year scores well in politics this year. Whether it keeps being right is the thing the score cannot know.
• "Potential insider" is a statistical flag for a new, concentrated, well-timed account. It is not a finding that anyone traded on non-public information, and the vendor's own label is careful to say "potential". Some flagged wallets will be exactly what they look like. Others will be a large trader's fresh address, or somebody who was lucky once.
• The landing page leads with one flagged account's win. That is one result the vendor chose to show. No false-positive rate or hit rate is published, and none has been checked here.

Integrations

An API, documented in public. 42 endpoints in seven groups, published as an OpenAPI 3.1 spec, with bearer-token authentication. It covers smart-money flow, unusual trades, per-market trades, positions, OHLC history, a live order-book snapshot and an insider-trade timeline per market. One endpoint lists the open prediction markets tied to a stock ticker, which is where this product meets the options business it sits inside.

A WebSocket. Live Polymarket fills for the markets on your watchlists, with maker and taker address, side, size, fee and timestamp.

The main Unusual Whales API also carries a smaller set of /api/predictions endpoints (insiders, smart money, whales, market positions and liquidity). Unusual Whales runs a general MCP server for its stock and options data. Nothing we read says that server covers prediction markets, so the MCP flag above is off. There is no SDK and no export beyond the API.

Limitations

One venue. Polymarket only, by the vendor's own API guide. No Kalshi and no Polymarket US.

The scores are the product, and their weights are not published. The inputs to the Smart Score are named, but how they are weighted and how a bot is told apart from a person is not. A score out of 100 invites more confidence than an undisclosed formula has earned.

A flag is not a trade idea. Everything this product emits is a label on someone else's position: a score, a Z-score, a size threshold. Acting on one means following a wallet into a market after it has already moved the price. By the time an alert reaches you, the book reflects what the flagged account did.

The terms predate the product by five years. The document dated June 2021 speaks of options, exchange fees and lifetime memberships, and nothing in it addresses prediction-market data. The footer adds that Unusual Whales is not a registered broker-dealer or investment adviser.

The old URLs moved. Bookmarks and integrations built against hashdive.com page paths now land on Unusual Whales pages. Anything that scraped the old Streamlit app has nothing left to read.

Alternatives

Polysights runs a free insider-finder screen on Polymarket with no published pricing, and PrediEdge runs a free tape of large fills tagged by price impact, with a longshot screen it also labels potential insider activity.

For trader P&L and leaderboards, Polymarket Analytics has a 20 USD paid tier and an API, Predicts.guru is free with no account, and Convexly publishes its method for judging a wallet.
