Flags “fresh” or previously dormant wallets making large, concentrated bets shortly before major news breaks, using a Z-Score system to rank how statistically unusual the activity is compared to normal market behavior.
Unusual Predictions Review 2026: The Insider-Detection Tool Formerly Known as Hashdive
Unusual Predictions is a Polymarket analytics platform built to flag insider-style trading, track whale activity, and rank top-performing wallets by niche. If the name doesn’t ring a bell yet, the product does: Unusual Predictions is the rebrand of Hashdive, the standalone Polymarket and Kalshi analytics tool that merged into Unusual Whales in January 2026. This Unusual Predictions review covers what changed in that merger, what the prediction markets tool does now, what it costs, and whether it’s worth using.
Quick Verdict on Unusual Predictions
Unusual Predictions is an analytics layer that sits on top of Polymarket, built to surface potential insider trades, whale positioning, and top-performing wallets by category.
The single best reason to use it: its Insider Detection module and Z-Score ranking system are built on years of Hashdive’s own data work, now backed by Unusual Whales’ much larger surveillance infrastructure and community.
The biggest limitation is scope. Where Hashdive originally covered both Kalshi and Polymarket, Unusual Predictions currently covers Polymarket only, so Kalshi traders get nothing here.
Our take: if you trade Polymarket and want a data-driven way to spot unusual or informed-looking bets before they resolve, Unusual Predictions is worth adding to your workflow. If you split your trading toward Kalshi, or you were using Hashdive specifically for its Kalshi coverage, this rebrand is a downgrade for you.

What Is Unusual Predictions?
Unusual Predictions is Unusual Whales’ analytics product for Polymarket, built around spotting unusual or potentially informed trading activity before a market resolves. It’s one of several Polymarket analytics tools on the market, but its foundation is different from most: it was built on Hashdive’s existing data infrastructure, following a January 2026 announcement that Hashdive was joining Unusual Whales to build the product together.
Hashdive itself had spent years refining wallet scoring and market-flow analytics with an active trading community stress-testing the approach before the merger. Unusual Whales, founded in 2020 as a self-funded, small options-flow and dark-pool data platform for retail traders, brought its own years of experience flagging insider-style activity in equities and politician trading disclosures to the new product. That combined background is a real trust signal in a niche where plenty of tools have no verifiable data pedigree at all.
Key Features of Unusual Predictions
Unusual Predictions organizes its analytics around three core modules, plus the API access it inherits from the wider Unusual Whales platform:
Insider Detection
Whale Tracker
Surfaces large positions on Polymarket, along with the historical track record and profit and loss of the accounts behind them, so you can judge whether a given whale has actually been profitable before treating their position as a signal.
Smart Money
Ranks top-performing wallets by category, including politics, sports, and crypto, letting you filter for specialists in a specific niche rather than sorting through a single undifferentiated leaderboard.
Market Scoring Tags
Individual markets get tagged with signals like Contrarian Whales (large bets against prevailing sentiment), Momentum (large bets aligned with the current price direction), and Closing Soon (markets resolving within seven days), which helps prioritize what to look at first.
API Access
Developer access to Unusual Whales’ broader data API is available as a separate paid add-on, useful if you want to build your own alerts or automation on top of the underlying data rather than relying on the dashboard.
How Unusual Predictions Works
The core mechanic worth understanding is the Z-Score system behind Insider Detection. Rather than just showing you every large trade, Unusual Predictions compares a wallet’s current behavior against its own historical pattern (or the absence of one) and assigns a score based on how anomalous the activity looks. A dormant or brand-new wallet that suddenly places a large, concentrated bet tied to a specific, imminent news event scores higher than a routine trade from an active, diversified trader.
For example, in the tool’s own launch materials, a newly created wallet placed a small number of large, concentrated bets tied specifically to a geopolitical event shortly before it happened, then saw that position pay off substantially once the news broke. That’s the pattern the Z-Score system is designed to catch and flag for other users, rather than something you’d need to notice manually by scanning wallet histories one at a time.
Supported Platforms and Markets
| Platform | Supported | Market Categories Covered | Notes |
|---|---|---|---|
| Polymarket | ✅ Yes | Politics, sports, crypto, and other active Polymarket categories | Primary and currently only platform covered |
| Kalshi | ❌ No | Not covered | Covered under the original standalone Hashdive product; dropped in the move to Unusual Predictions |
This is the most important change to understand if you used Hashdive before the merger. Hashdive’s own tool covered both Kalshi and Polymarket. Unusual Predictions, as relaunched under Unusual Whales, is built and marketed specifically around Polymarket. If Kalshi coverage was the reason you used Hashdive, that functionality isn’t part of this product as of this writing, and it’s worth checking Unusual Whales’ own site directly to confirm whether that’s changed before assuming otherwise.
Pricing of Unusual Predictions
Unusual Predictions is sold as a standalone subscription, separate from Unusual Whales’ broader options-flow and dark-pool plans:
- Monthly plan: $20/month, giving full access to Insider Detection, Whale Tracker, and Smart Money.
- Annual plan: $204/year, which works out to roughly $17/month, a modest discount over paying monthly.
- What’s included: Both plans unlock the same feature set. There’s no lower-tier, limited version of Unusual Predictions itself; the difference between the two options is purely monthly versus annual billing.
- Free tier: No free tier is confirmed specifically for Unusual Predictions. Unusual Whales’ broader platform has historically offered a limited free plan for its options and equities tools, but that doesn’t extend prediction-markets access.
- API access: Sold as a separate paid add-on from the core subscription, for anyone who wants programmatic access to the underlying data.
At $20/month, Unusual Predictions is priced in line with, or slightly below, several other paid analytics tools in this cluster, and the annual plan is worth considering if you already know you’ll use it past the first couple of months.
Getting Started with Unusual Predictions
Setup runs through Unusual Whales’ existing account system rather than a standalone signup flow. Estimated total setup time: under 5 minutes if you don’t already have an account.
- Create an Unusual Whales account at unusualwhales.com, or log in if you already use the platform for options or equities data.
- Subscribe to Unusual Predictions for $20/month or $204/year.
- Navigate to the Predictions section of the dashboard to access Insider Detection, Whale Tracker, and Smart Money.
- Browse flagged markets and wallets using the built-in tags (Contrarian Whales, Momentum, Closing Soon) to prioritize what to look at.
- Drill into a specific wallet or market for full trade history, position size, and Z-Score detail before deciding whether to act on it.
No wallet connection is requested at any point in this flow. Unusual Predictions reads public Polymarket blockchain data and displays it inside your Unusual Whales account; it doesn’t ask for a crypto wallet, private keys, or trade-execution permissions.
Is Unusual Predictions Legit and Safe to Use?
Yes, based on everything publicly verifiable, Unusual Predictions is legit. It isn’t run by an anonymous team. Unusual Whales has been publicly operating since 2020 as a self-funded, small team with a well-documented track record in options flow and dark-pool data, and it carries a large, established following on X and a public LinkedIn presence. Hashdive, the product Unusual Predictions is built on, was founded by data engineer Niko Kudriastev, and that team’s work is what Unusual Whales specifically cited as the foundation for the new product’s scoring system.
On the access side, there’s nothing to hand over. Unusual Predictions doesn’t request a crypto wallet connection or any trade-execution permission. It’s a read-only research layer built on public Polymarket blockchain data, viewed through a standard subscription account, so the usual custodial-versus-non-custodial risk questions that apply to trading bots simply don’t apply here.
The one thing worth watching, and disclosing plainly: this is a genuine product consolidation, not a simple renaming. Hashdive’s original site remained active only through a transition window after the January 2026 announcement, and its Kalshi coverage didn’t carry over into Unusual Predictions. If you’re evaluating this tool based on older information about Hashdive, some of what you read may no longer apply. We evaluate every tool in this cluster against our own prediction market tools methodology, weighing transparency, functionality, and real editorial testing rather than manufactured review scores.
Pros and Cons of Unusual Predictions
Pros
- Backed by Unusual Whales, a publicly identified, multi-year operator with a real track record in flow and insider-activity data, not an anonymous crypto-native startup.
- Inherits years of wallet-scoring and market-flow refinement from Hashdive's original, community-tested approach.
- Z-Score-based Insider Detection surfaces genuinely hard-to-replicate signal: fresh or dormant wallets making concentrated, well-timed bets.
- Read-only by design. No wallet connection or trade-execution access requested anywhere in the product.
- Market tags (Contrarian Whales, Momentum, Closing Soon) help prioritize what to look at instead of scanning a flat, undifferentiated list.
- API access available for anyone who wants to build automation on top of the underlying data.
- Transparent, straightforward pricing at $20/month or $204/year, with no confusing tier structure to sort through.
Cons
- Kalshi coverage was dropped in the move from Hashdive to Unusual Predictions, so Kalshi-focused traders get no value here at all.
- No dedicated free tier confirmed for Unusual Predictions itself, so you can't test it without paying.
- As a recently merged product, some documentation and third-party coverage still describes the older, separate Hashdive rather than the current Unusual Predictions feature set.
Who Is Unusual Predictions For?
👍 Use it if you:
- Trade Polymarket regularly and want a data-driven way to flag potentially informed or unusual bets before a market resolves.
- Already use Unusual Whales for options or equities data and want prediction-market coverage inside the same account.
- Want wallet-level whale tracking with real historical performance, not just a raw feed of large trades.
⚠️ Look elsewhere if you:
- Trade primarily on Kalshi, since Unusual Predictions doesn’t cover it at all.
- Want to test the tool for free before committing, since no free tier is currently available.
Unusual Predictions Alternatives
Unusual Predictions isn’t the only option for deeper Polymarket and Kalshi analytics, especially now that its own Kalshi coverage has gone away. Here’s how it compares to a few other tools worth knowing about.
| Tool | Category | Platforms | Pricing | Best For |
|---|---|---|---|---|
| Unusual Predictions | Analytics & Dashboards | Polymarket | $20/month; $204/year | Insider-style detection and whale tracking on Polymarket |
| Polymarket Analytics | Analytics & Dashboards | Polymarket | Free plan; $20/month premium | Broad Polymarket wallet leaderboards and market discovery |
| Kalshinomics | Analytics & Dashboards | Kalshi and Polymarket | Free | Traders who need coverage on both platforms in one dashboard |
| Stand.Trade | Aggregators & Terminals | Polymarket and Kalshi | Free | Trading both platforms from a single terminal rather than a research dashboard |
Polymarket Analytics covers similar ground to Unusual Predictions on wallet leaderboards and market discovery, and it remains free at its core tier, though it doesn’t carry the same insider-detection framing.
Kalshinomics is the pick if Kalshi coverage matters to you, since it’s free and covers both Kalshi and Polymarket in one place, unlike Unusual Predictions’ current Polymarket-only scope.
Stand.Trade is worth a look if what you actually want is a place to place trades across both platforms, rather than a pure research and detection layer sitting alongside your regular trading flow.

Final Verdict
Unusual Predictions does one thing well: it takes years of Hashdive’s wallet-scoring and market-flow work and backs it with Unusual Whales’ much larger surveillance infrastructure and audience, producing a genuinely useful Z-Score system for spotting unusual, potentially informed Polymarket activity. What holds it back is the transition itself. Kalshi coverage is gone, and there’s no dedicated free tier to try it risk-free before paying $20/month. If you trade Polymarket and want a credible, well-backed way to flag unusual wallet activity, Unusual Predictions is worth using. If you need Kalshi coverage, you’ll want to pair it with, or choose instead, one of the alternatives above.
Is Unusual Predictions legit?
Yes. Unusual Predictions is built and operated by Unusual Whales, a self-funded data analytics company that’s been publicly operating since 2020, on a foundation built by Hashdive, whose founder and community had already spent years refining the underlying wallet-scoring approach. It doesn’t request wallet connections or trade-execution access, since it only reads public Polymarket data.
No. Unusual Predictions costs $20/month, or $204/year if billed annually. There’s no free tier confirmed specifically for this product, so you’ll need to subscribe to access Insider Detection, Whale Tracker, and Smart Money.
No. Unusual Predictions reads public Polymarket blockchain data and displays it through a standard Unusual Whales account login. It never asks you to connect a crypto wallet or grant trade-execution access.
No, not currently. Unusual Predictions covers Polymarket only. This is a change from the original standalone Hashdive product, which covered both Kalshi and Polymarket before the January 2026 merger into Unusual Whales.
For active Polymarket traders who want a credible, well-backed way to flag unusual or potentially informed wallet activity, yes, especially at $20/month. It’s less worth it if you need Kalshi coverage, since that’s no longer part of the product.
Cancellation runs through your Unusual Whales account settings, since Unusual Predictions is billed as a subscription tied to your Unusual Whales login. Confirm the current cancellation steps directly on unusualwhales.com before subscribing, since specific account flows can change.
Yes. API access to Unusual Whales’ underlying data is available as a separate paid add-on from the core subscription, for developers who want to build their own alerts or automation on top of it.
