Something unusual has been happening in prediction markets this year. While the narrative has focused on volume records and meme coin frenzies, a cohort of quant funds and algorithmic traders have been quietly building position s– not on crypto price action, but on Fed meeting outcomes, tariff announcements, and geopolitical escalations. The volumes were not small.
This is the quietest big shift in crypto market structure this year.
Polymarket's announcement this week of the most comprehensive infrastructure overhaul in its history – new contracts, a rebuilt order book, a proprietary collateral token, and a rebuilt client SDK – landed with fanfare in crypto circles. But the deeper signal was hiding in the fine print. EIP-1271 signature support, which enables smart contract wallets and opens the door for algorithmic execution. Builder codes for onchain order attribution, allowing sophisticated participants to track their positions and strategies with precision. These are not features for retail traders arguing about politics on X. These are the plumbing changes that attract quant desks.
The numbers explain the urgency. Polymarket has processed over $20 billion in cumulative volume. Weekly trading has sustained above $900 million. ICE, parent of the New York Stock Exchange, has now committed $1.6 billion across two funding rounds. When the NYSE's owner is writing nine-figure cheques into a prediction market platform, the signal is clear: it is financial infrastructure being built in public
The regulatory architecture is following suit. The CFTC approved Kalshi's election contracts in late 2024, clearing the path for regulated prediction markets on U.S. soil. Crypto.com's CDNA exchange launched OG.com in February, offering prediction contracts with institutional-grade entry fees. These are complementary rails serving an audience that is increasingly sophisticated about how prediction markets work as information discovery mechanisms.
The interesting structural question is what happens to that information as the audience professionalizes.
Prediction markets derive their edge from the "wisdom of the crowd," which is the idea that a sufficiently diverse set of participants, each with their own information and incentives, produces forecasts that are hard to beat systematically. That edge is theoretically maximized when participation is broad and participants are genuinely informed about different things. The concern among researchers who study these markets is that as algorithmic and institutional participants dominate volume, prices begin reflecting the views of a narrower, and potentially correlated, set of actors. The crowd gets smaller and more homogeneous even as the money flowing through it gets larger.
Polymarket's infrastructure changes are designed, at least partly, with this tension in mind. Opening up to smart contract wallets and providing better tools for algorithmic execution expands the set of participants who can interact with the platform on their own terms. Whether that broadens or narrows the information ecology is an open empirical question.
What is not in question is the direction of travel. Circle's partnership with Polymarket — which underpins the new Polymarket USD collateral token, replacing bridged USDC.e with a native, platform-controlled stablecoin backed 1:1 by USDC, signals a desire for infrastructure ownership. When you control your collateral token, you control your settlement rails. That is a different ambition than operating a frontend on top of someone else's DeFi primitives.
The broader prediction market ecosystem is fragmenting into distinct layers. At the top, platforms like Polymarket are building proprietary, regulated-adjacent infrastructure with institutional ambitions. Below that, smaller crypto-native markets are competing on transparency, novel contract types, and community governance. Below that, traditional financial exchanges are beginning to offer regulated prediction products to audiences that will never touch a crypto wallet. Each layer serves a different user, and the arbitrage between them is itself becoming a source of opportunity.
None of this means prediction markets are "solved" or that their information is reliably superior to other forecasting methods. The record on election markets is mixed; economic prediction markets have a history of trending toward consensus too early and then overcorrecting. But the infrastructure being built underneath them – the contracts, the collateral rails, the execution clients – is starting to look less like a crypto experiment and more like the kind of plumbing that attracts serious capital.
The crowd is getting bigger. Whether it is getting wiser is the question that quant funds are now paid to answer.
