Polymarket Hits $220 Million in Trading on Single-Stock Bets from 31,000 Traders

Prediction markets are getting serious about stocks. Polymarket International crossed $220 million in trading volume on share-price contracts tied to companies like Nvidia, Alphabet, Apple, and Tesla — pulled from roughly 31,000 traders who apparently don’t want to buy shares outright but still want to bet on where they go.

The numbers are big. Nearly 60% of that volume came from single-stock contracts alone. The rest spread across broader market indices and exchange-traded funds, but the clear winner in terms of trader interest was individual company bets. That’s a lot of speculative money moving through a platform that operates offshore and blocks — or at least claims to block — US users entirely.

How These Contracts Actually Work

It’s pretty simple on the surface. A trader picks a company, say Apple, and bets yes or no on whether the stock hits a specific price by a set date. No shares change hands. No dividends. No voting rights. If the contract resolves in your favor, you get paid. If not, nothing. And if you change your mind before resolution, you can close the position early.

One wallet caught the attention of Allium, a blockchain research firm. That single wallet ran up $175,000 in volume across roughly 1,300 trades tied to Apple. The strategy was built to generate a small profit either way — whether the outcome landed yes or no. Allium didn’t disclose further details on exactly how the strategy was constructed, so the mechanics there are still murky.

The contracts themselves are specific. Two contracts that look nearly identical on paper can resolve differently because of small variations in observation times or settlement rules. A trader betting on Nvidia at a certain price by a certain hour might win while another trader with a similar view loses, just because the contracts had different cutoff windows. That kind of precision matters a lot, and it’s probably one reason the platform attracted traders who know what they’re doing.

None of the four companies — Nvidia, Alphabet, Apple, Tesla — responded to inquiries about their involvement or their views on markets that let people speculate on their share prices. No comment from any of them. That leaves a gap in understanding how these firms think about platforms that essentially turn their stock performance into a yes-or-no game.

SEC and CFTC Are Watching Closely

Here’s where it gets complicated. In the US, contracts that reference individual company stock prices are generally treated as security-based swaps. The SEC oversees those, and they’re mostly restricted to professional market participants. Not retail traders sitting at home. Polymarket International runs offshore, and its US-regulated exchange — the one that operates under CFTC oversight — doesn’t offer individual stock markets at all. That separation is deliberate.

But the line between what’s a commodity-linked event contract and what’s a security-based swap isn’t clean. In June, the SEC and CFTC put out a joint request for public input specifically on that regulatory boundary. They want to figure out where equity-linked event contracts land and which agency has jurisdiction over them. The outcome of that review is still pending.

It’s not a small question. The answer will shape whether platforms like Polymarket can ever offer these products to US users legally, and under what framework. Right now, the offshore structure keeps Polymarket International operating in a gray zone — technically outside US reach, but attracting serious trading volume that regulators can see.

What the Volume Says About Demand

$220 million is hard to ignore. It’s not just a number — it’s a signal that there’s real appetite for this kind of instrument. Traders want exposure to stock price movements without the friction of actual ownership. No brokerage account required. No options chain to navigate. Just a binary bet with a defined payout.

And it’s not casual money. The Apple wallet alone — one wallet, 1,300 trades, $175,000 — points to traders running structured strategies, not just guessing. That’s the kind of activity that makes regulators nervous, because it starts to look like a derivatives market operating outside the rules that govern derivatives markets.

The CFTC already regulates Polymarket’s US exchange. But that entity doesn’t touch individual stocks. The offshore arm does, and that’s the one doing $220 million in volume with 31,000 participants. Whether those participants are actually all non-US is something the platform says it enforces — but enforcement of geographic restrictions in crypto-adjacent markets has always been a soft spot.

Broader context: prediction markets have grown fast across Asia and other regions where access to traditional financial products can be limited or expensive. Single-stock speculation through binary contracts fills a gap. Polymarket International isn’t the only platform exploring this space, but it’s generating some of the most visible numbers right now.

The SEC and CFTC’s joint review in June was the clearest sign yet that regulators aren’t ignoring equity-linked event contracts. The agencies solicited public input, which means they’re building a record before making a formal determination. That determination will probably define the next phase of this market — who can offer these products, to whom, and under whose watch.

Polymarket International’s offshore operation generated $220 million before regulators even finished asking the public what they think.
