Smart money doesn't stay smart

A centralized exchange keeps its order flow to itself. Hyperliquid is a DEX, so every fill is public and signed by the wallet that made it. That's a strange and powerful thing: you can watch every trader on the venue, name by name, month after month. So the obvious question almost asks itself — why not just find the wallets that make money and copy them?

We ran the experiment. Each month we score roughly 108,933 wallets on BTC alone (and tens of thousands more across 260-odd other markets): how much they trade, how often they win, how much they make, and how toxic their flow is — how far the price runs against you in the minutes after they hit your quote. Then we asked the only question a copy-trader cares about: does any of it carry over to next month?

Last month's hero, next month's goat

Here's the same picture for three different wallet traits. Each grid sorts wallets into deciles by a trait this month (bottom-to-top) and asks where they land next month (left-to-right). A bright diagonal means "you stay where you were" — the trait persists. All-bright means it's a coin toss.

Rows = this month's decile (low at bottom); columns = next month's decile. Brighter = higher probability. Pooled over 10 major markets, 2025-08..2026-06, wallets active in both months.

Look at the middle panel. If trading profit were skill, big winners would stay winners and the grid would light up along the diagonal like the win-rate panel on the left. Instead it forms an X: the wallets with the largest realized PnL this month are almost as likely to plunge to the bottom decile next month as to repeat at the top. That's the fingerprint of variance, not edge — the same accounts take the biggest swings in both directions. The bright core in the centre is the quiet majority whose PnL hovers near zero and stays there. Toxicity (right) barely persists at all.

What does persist is style, not skill

Rank every trait by how strongly it carries month-to-month (Spearman correlation of a wallet with itself, one month later). The pattern is stark. The things that persist describe who a wallet is and how it trades — how much size it pushes, the fees it pays, its habitual win rate. The one thing that doesn't persist is the thing you'd actually want to copy: whether it makes money.

Trading volume is almost perfectly sticky (ρ ≈ 0.81) — whales stay whales. Win rate is moderately sticky (ρ ≈ 0.22), but a high win rate is a style: scalpers bank many tiny gains and take rare large losses, so a wallet's win rate tells you how it trades, not whether it profits. Realized PnL (ρ ≈ 0.08) and 5-minute toxicity (ρ ≈ 0.01) are essentially memoryless. Copying last month's leaderboard is copying a coin flip.

The shape of the crowd

Two more facts explain why the leaderboard is so noisy. First, most wallets lose: in every full month, 54% of the wallets trading BTC finish the month with negative realized PnL. The distribution is fat-tailed and roughly balanced around zero — a few big winners, a few big losers, and a huge pile clustered near break-even before fees.

Second, volume is extraordinarily concentrated. A handful of accounts do almost all the trading, and the long tail barely moves size. So a naive "top PnL" ranking is dominated by whoever happened to take the biggest position into the biggest move — survivorship and variance wearing the costume of skill.

Where the edge actually is

So is wallet data useless? The opposite — but the edge isn't in any single column, and it isn't in copying winners. It's in the interaction of many weak, orthogonal behaviours (they share a mean absolute correlation of only ≈0.11). No one of them forecasts next month; combined in a non-linear model, they do. That's the claim we validated: a tree that scores every wallet's next-month PnL and toxicity, out-of-sample the hard way.

The validation survives the tests that kill most "smart money" claims. We measure walk-forward, only scoring months the model was fit before. We hold out whole coins — leave-one-coin-out — so the reported skill is on markets the model never trained on, and it replicates. A no-shared-wallet variant, where train and test wallets don't overlap, actually strengthens it: the model learns behaviour, not a memorized list of addresses. And the tell-tale negative control — whether the same signal predicts the coin's price return — comes back at ≈0. This forecasts wallet behaviour, not the market.

See it for yourself

Everything above is built from Hyperliquid's public signed fills. We don't expose that per-wallet feed ourselves — it's public, if you'd rather wrangle it raw — but we do ship its market-level distillation: order-flow OHLCV, funding and positioning, cleaned, checked and served as Parquet or over the API.
