Polymarket's Real Scoreboard: 69% of Retail Wallets Are Underwater

Galaxy Research just put a number on something every degen already suspected. 69.2% of retail Polymarket accounts finished below break-even.

That's not a vibe. That's 2.9 million wallets and $338.9 million in combined losses. The chain doesn't lie.

The Setup

Here's how the study came together. Galaxy pulled Polymarket's full on-chain settlement record. Every trade, every payout, every wallet. The oracle network Stork curated the data, which matters because this isn't a survey and it isn't self-reported. It's the actual ledger.

The scope matters too. This only covers the international platform, which still runs separately from the US app.

So what does the distribution actually look like? Roughly seven out of ten retail wallets ended in the red. The winners exist. They always do. But they're a small minority, and the money they pulled came straight out of everyone else's bags.

Prediction markets look like skill. Mostly they're a confidence tax.

The Damage

Let's talk about who got hurt.

$338.9 million. That's the aggregate hole. Spread across 2.9 million wallets, it averages out to something like $115 per account. Which sounds small until you remember these are retail traders. People aping $50 here and $200 there, chasing a tournament upset or an election shock.

But the average hides the real story. The losses aren't evenly spread. A big chunk of that red belongs to a smaller pool of wallets that went large and went wrong. Meanwhile the top decile of accounts, the whales who move size and price real information, they're sitting on the other side of the trade.

Real talk: if you're a retail trader on a prediction market, you aren't competing against other casuals. You're competing against people running models, bots, and an information edge you can't see.

And honestly? Polymarket's interface makes it feel easy. Pick a side. Watch the odds move. Cash out. It's built to feel like a game you can win. The settlement data says most people don't.

Why does this matter beyond one platform? Because prediction markets keep getting pitched to the public as the next big thing in information and finance. The pitch is that they aggregate truth. The data says they also aggregate losses for the people least equipped to absorb them.

What to Watch

The US app is the next frontier. It runs separately and it's regulated. That changes the math. Higher compliance costs, fewer markets, an order book that looks more like a sportsbook than an offshore casino.

Watch the next quarterly volume prints. If US retail piles in at the same rate, expect a similar pattern to show up on a regulated book within two quarters.

Watch Stork's data pipeline too. If Galaxy's methodology holds up under scrutiny, other researchers will run the same study on every competing venue. The number won't be identical. The shape of the curve will be.

And watch the wallets that keep winning. If a small cohort consistently beats break-even across thousands of markets, that's not luck. That's an edge. That's the signal.

Look, prediction markets aren't broken. They produce real information, and the sharp money is doing real work. But "retail can play too" was always a marketing line, not a thesis. The settlement record just priced it out in public.

69.2% of people lose. That's the number. Plan accordingly.
