Polymarket is operated by Blockratize Inc., a Delaware-registered company. The international platform runs through a related entity called Adventure One Ltd, incorporated in Panama. The US platform operates as QCX LLC d/b/a Polymarket US.
The founder and CEO is Shayne Coplan. Here’s the full story.
Shayne Coplan: The Founder
Shayne Coplan was born in 1998 in New York City. He developed an early interest in financial markets — at age 14, after reading Michael Lewis’s Flash Boys, he wrote an email to the SEC about high-frequency trading practices.
Coplan studied computer science at NYU but dropped out to pursue Polymarket full-time. He and a small founding team started the company in what he described as a converted bathroom office in New York.
Polymarket launched in June 2020 with a straightforward premise: let anyone trade on real-world events using a decentralized prediction market.
Funding History
Polymarket has raised more funding than any other prediction market by a significant margin.
| Round | Date | Amount | Lead Investors |
|---|---|---|---|
| Seed | Aug 2020 | $4M | Union Square Ventures, Polychain Capital |
| Series A | Mar 2022 | $25M | Founders Fund, Dragonfly Capital |
| Series B | May 2023 | $45M | Founders Fund |
| Series C | Nov 2024 | $150M | Y Combinator Continuity, Polychain Capital |
| Strategic | Oct 2025 | $2B | Intercontinental Exchange (ICE) |
| Follow-on | Mar 2026 | $600M | ICE-led |
| Total | ~$2.8B+ |
The October 2025 investment from Intercontinental Exchange — the parent company of the New York Stock Exchange — valued Polymarket at approximately $9 billion. It was a watershed moment for the prediction markets industry: the world’s largest exchange operator betting that event-based trading is a durable market category.
The valuation has kept climbing since. The March 2026 $600 million follow-on valued Polymarket at roughly $15 billion, and by spring 2026 the company was reportedly in talks with investors at valuations as high as $20 billion — though no round has closed at that level yet.
The CFTC Settlement (2022)
In January 2022, Polymarket settled with the U.S. Commodity Futures Trading Commission (CFTC) for $1.4 million. The CFTC alleged that Polymarket had operated an unregistered swap execution facility, making its binary event contracts available to US users without proper regulatory approval.
Polymarket settled without admitting wrongdoing. As part of the settlement, the company agreed to block users in the United States — restrictions that remain in place on the international platform today.
The fine was relatively modest given Polymarket’s trading volumes, and the company continued operating internationally without interruption.
The Path Back to the US Market
After the CFTC settlement, Polymarket spent years navigating a path to legal US re-entry.
In July 2025, Polymarket acquired QCEX (also known as “QCX”) for approximately $112 million. QCEX held a CFTC-licensed exchange designation — specifically the same regulatory structure used by competitor Kalshi. The acquisition gave Polymarket the regulatory infrastructure to legally offer prediction markets to US customers.
The US platform relaunched on December 2, 2025, initially as an invite-only sports prediction app. The waitlist was dropped in May 2026, opening the iOS app to US users (Android and web are still pending). It operates separately from the international platform with its own markets, liquidity, and fee structure — see our full US status page for the state-by-state legal picture.
The two platforms are not connected. Positions, balances, and accounts are completely separate.
Business Model
Polymarket earns revenue from trading fees.
The fee structure has evolved significantly:
- 2020–2024: Minimal or zero fees while building market share
- 2025: Zero fees maintained through most of the year to compete with Kalshi’s US relaunch
- March 30, 2026: Taker fees broadly introduced across the international platform
Current taker fees vary by market category, with max fees ranging from $0.75 to $1.80 per 100 shares. Geopolitical markets are fee-free. Makers (traders who add liquidity) pay zero fees and receive rebates. The full fee breakdown is covered in the Polymarket Fees article.
Scale and Metrics
As of mid-2026, Polymarket is the dominant prediction market globally by trading volume:
- Valuation: ~$15 billion (March 2026 round), with reported talks at up to $20 billion
- Total raised: ~$2.8 billion
- Cumulative trading volume: Billions of dollars since launch
- Peak activity: 2024 US presidential election period saw record daily volumes
- Markets: Hundreds of active markets at any time, spanning politics, sports, crypto, finance, economics, culture, and tech
- Countries: Available in 160+ countries (blocked in approximately 34)
- Blockchain: Polygon (Ethereum Layer 2)
- Settlement currency: PUSD (Polymarket’s own dollar-pegged stablecoin; deposits in USDC and 21 other tokens auto-convert)
How Polymarket is Different From a Casino or Sportsbook
Polymarket holds no positions. It does not bet against its users. Unlike a sportsbook that sets odds to ensure a margin, Polymarket is a two-sided marketplace — all trading happens between users, and Polymarket earns only the fee on each transaction.
This structure means Polymarket’s revenue scales with trading volume, not with user losses. A profitable Polymarket user is not a cost to the company — they’re a source of more trading.
The Broader Polymarket Ecosystem
Polymarket’s contracts run on the Polygon blockchain using the Conditional Token Framework (CTF) — an open-source smart contract standard. This means:
- Positions are recorded on-chain, not in Polymarket’s database
- The CTF contracts are publicly verifiable
- Third-party tools can read positions and liquidities directly from the blockchain
- In principle, positions can be held and traded outside the Polymarket interface
Outcome resolution uses the UMA Optimistic Oracle — an independent protocol where anyone can propose and dispute market outcomes. Polymarket does not unilaterally decide results; the oracle system does. For a full explanation, see How Polymarket Markets Resolve.
What the Company’s Evolution Looks Like From the Trading Floor
Corporate milestones are one thing — here’s how the last year of company news has actually felt as someone who trades on Polymarket daily.
The ICE investment hasn’t changed the product — yet. Nobody trading on the platform can tell you what a $2.6 billion commitment from the NYSE’s parent company means day-to-day, because so far the experience is much the same as before. What it means longer term is genuinely hard to say. The honest read is that it’s a bet on the category, not a redesign of the platform.
The US/international split is strange from a user’s perspective. The US product is currently the weaker of the two — an iOS-only app with sports markets, while the international exchange has the breadth and the vast majority of the liquidity. As an international user I’d love to see the two unified, but my understanding is US regulations don’t allow it. Since the liquidity is mostly international anyway, the split matters less in practice than it looks on paper.
The fee rollout was rough; the fees themselves make sense. The March 2026 fee introduction was poorly communicated and buggy in its first weeks. That said, I’m genuinely glad fees exist — I want Polymarket to be a sustainable business for the long haul, and the taker-only model is the right shape: makers pay nothing and the rebate program meaningfully rewards providing liquidity. My one criticism is that some categories are priced too high — taker fees at the top end make active trading difficult in those markets, and I’d expect the schedule to be tuned again.
