Polymarket

IWhat it does

Polymarket runs markets where each contract pays $1 if a stated event happens and $0 if it does not. A contract trading at 63 cents says the crowd puts the odds near 63 percent. Traders buy and sell these contracts with each other, and the price moves as news arrives. The firm does not take the other side of the bet in the usual case. It runs the venue and the matching engine. Popular markets include sports outcomes, elections, crypto prices and world events.¹⁰⁹

There are two Polymarket venues, and the difference matters. The first is the original international exchange, built on a blockchain and settled in a dollar-linked crypto token. It has been closed to US residents since a January 2022 settlement with the US Commodity Futures Trading Commission, the CFTC, which is the federal regulator of futures and similar derivatives.¹³ The second is Polymarket US, a regulated exchange that the company got by buying a licensed firm in 2025.³⁴

The US return came in steps. In July 2025 the company said it had closed the purchase of QCEX, a CFTC-licensed exchange and clearinghouse, for $112 million.⁶ The CFTC’s own register shows QCX LLC as a designated contract market from 9 July 2025, now trading under the name Polymarket US.⁴ In September 2025 the CFTC took a no-action position on some swap reporting rules, which the company’s chief executive described as a green light to go live.³ A no-action position means the staff does not plan to recommend enforcement for that specific point. It is narrower than a general approval.

On 24 November 2025 the CFTC signed an amended order of designation for Polymarket US.⁵ Press coverage says it lets the exchange take customers through brokers and futures commission merchants, which are registered intermediaries.⁶ I could not read the order’s text, so I cannot say what conditions it carries. A Reuters report says the exchange was opened to the public about six weeks before 26 June 2026.¹⁰

IIHow it makes money

For most of its life Polymarket charged no trading fee. That changed in 2026. Sacra, a research firm, reports that fees began in January 2026 on short-term crypto markets, then reached sports in February and a broader set in March.⁹ Sacra lists a taker fee schedule for the international exchange from 30 March 2026, ranging from 0.03 to 0.07 by category, with geopolitics free. A taker is a trader who removes an existing offer from the book. Makers, who post offers, pay nothing and get rebates. On the US exchange, from 3 April 2026, Sacra lists a flat 0.05 taker fee with a maker rebate.⁹ These are one third-party’s description of the schedule. I did not find the company’s own fee page this session.

The result is a revenue number that jumped. Reuters, citing one person familiar with the matter, reported on 26 June 2026 that annualised revenue had passed $1 billion.¹⁰ Annualised means a recent period scaled up to a year. It is a run-rate, not audited annual revenue, and a quiet month can pull it down. Sacra’s own June 2026 estimate is also $1 billion, from zero in 2025.⁹ The company is private and has published no audited accounts that I could find.¹²

Other income streams exist but I cannot size them. ICE, owner of the New York Stock Exchange, became a global distributor of Polymarket’s event data for institutional clients in its October 2025 deal.¹ The same release mentions joint work on tokenization, which means putting assets on a blockchain. No revenue figure for either is public.

As a cross-check, I estimate that a $1 billion run-rate implies something like $8 billion to $10 billion of monthly notional volume at an effective fee near 1 percent of face value. That is my estimate, built from Sacra’s note that Kalshi’s take rate is roughly 1 percent and from Sacra’s global monthly volumes, so it only shows the figures are not obviously inconsistent.⁹

Revenue and volume figures. Each row says who reported it.

IIIThe market and the competition

The main rival in the US is Kalshi, a CFTC-regulated exchange that has held a licence longer. On 29 October 2026 CNBC reported Kalshi raised $1 billion at a $40 billion valuation, co-led by Sequoia Capital and Wellington Management, after a $22 billion mark in May and $5 billion in October 2025.¹⁶ Bloomberg, as relayed by TFN, put Kalshi’s annual revenue near $1.5 billion at the $22 billion stage.⁸ On the tracker I used, Kalshi’s October 2026 volume was $98.15 billion against $14.77 billion for Polymarket US, about 6.6 times larger.¹⁴ The tracker measures reported contract volume, so it is a rough guide.

That gap is a mixed picture. Polymarket’s international exchange is outside the tracker’s US scope, and its volume is not in that table. Sacra puts the US arm at roughly a fifth of Polymarket’s global volume in spring 2026.⁹ So Polymarket is smaller than Kalshi in the US, and I cannot say from public data how the two compare worldwide.

Volume is concentrated in a few topics. Sacra says sports were about 39 to 40 percent of Polymarket volume in 2026, politics 32 percent and crypto 20 percent.⁹ A crypto-news site reports that parlay-style combination contracts, launched in August 2026, made up more than half of activity in some weeks on the US exchange, with football the main driver.¹⁵ That site’s article was produced with AI assistance and names no data provider, so I treat it as indicative only.

Other competitors are not covered by the sources I opened. Brokerages, sportsbooks and crypto exchanges have launched or announced event contracts, but I could not verify specifics in this session, so I do not rate their threat.

Rules differ across the US states. A search summary I could not confirm in a primary court document says a federal appeals court split over whether states can apply gambling law to sports event contracts, and that the CFTC has begun suing states. I treat that as unverified, but it points to the central legal question for this whole sector: whether federal commodities law overrides state gambling law.

IVThe moat and how it could be disrupted

I rate the moat as contestable. The advantage is real: a prediction market is more useful when it has many traders, because that gives tighter prices and deeper books. Polymarket built that on its international exchange and has a recognisable brand among crypto-literate users. Its US exchange now has a regulatory licence, and the company has a strategic backer in ICE, which also distributes its data.¹⁴

But none of this is hard to copy. The product is a contract and a matching engine. Kalshi has the same federal licence and is ahead on volume in the US.¹⁴ Users can hold accounts at several venues at no cost, so switching costs are low. Liquidity tends to go where the best prices and the most traders are, and that currently points to Kalshi in the US. Polymarket’s international side has a clearer lead, but it depends on a legal posture that US regulators are again examining.¹³

A disruptor does not need to be a better product. It could be a distribution partner. If a large broker, sportsbook or payment app puts event contracts in front of its existing customers, it can borrow trust and skip the work of building a trader base. Polymarket has begun to answer this with intermediated access through registered brokers, and Covers reports a multi-year partnership with PrizePicks announced in November 2025.⁶ Those partners also have other options.

The platform also has a trust risk that is specific to this business. Markets must settle on a clear, fair rule for who won. Disputes over wording and over insider trading can damage a venue. In April 2026 US authorities charged a soldier with making about $400,000 from insider bets on the offshore exchange, according to Reuters. He has pleaded not guilty.¹³ Such cases do not say the company did wrong, but they make regulators pay more attention.

VThe numbers we can see

The public record is thin. There are no audited accounts, and no ICE-style filing that gives Polymarket’s own revenue. The best primary evidence on value comes from the investor side: ICE’s press releases and its stock-exchange filings. ICE has filed a quarterly report for the period ended 30 September 2026, dated 29 October 2026, but the copy I could open would not display its text, so I could not read any carrying value or gain.¹⁹ That is a gap I would close first.

Valuation marks line up as follows. In October 2025 ICE said it would invest up to $2 billion at roughly $8 billion before the investment, with no post-money number in the release.¹ Polymarket described it as a $9 billion post-money deal, per The Block.² Pre-money of $8 billion plus the full $2 billion would give $10 billion, while $9 billion fits roughly $1 billion actually invested at that point, which is how Sacra describes the first tranche.⁹ I use $9 billion as the company-reported figure and flag the gap.

On 27 March 2026 ICE said it completed a further $600 million direct cash investment, with up to $40 million of purchases from existing holders to come. ICE said it would then have completed its obligations under its arrangement, and that it would disclose the valuation after Polymarket’s fundraising is complete.⁷ Adding the pieces gives about $1.64 billion at most, which is my arithmetic.

In April 2026 Bloomberg reported talks to raise $400 million at about $15 billion post-money, with a round that could reach $1 billion.⁸ In August 2026 Bloomberg reported a target of more than $20 billion and said ICE could consider joining, per its chief executive.¹¹ On 31 August 2026 Bloomberg reported 1789 Capital was leading a round of about $1 billion at $21 billion post-money, adding about $300 million.¹² I could not open Bloomberg directly, so I rely on follow-up coverage. One outlet says the round had closed, and another says final terms could still change. I treat it as unconfirmed.

Ownership: a third-party estimate says ICE holds about 23 percent of outstanding shares and about 14 percent fully diluted after March 2026.⁹ Another report says about 22 percent.¹² These differ by a point and neither is from a filing I could read. Sacra also says ICE recorded a $389 million upward adjustment to its carrying value, and that adjustment is unconfirmed.⁹

On multiples: $21 billion over a $1.0 to $1.1 billion run-rate is about 19 to 21 times. For Kalshi, $22 billion over about $1.5 billion is about 15 times at that point.⁸ Kalshi’s $40 billion mark came in October 2026, and the article I opened did not give revenue for it.¹⁶ Revenue for both firms is event driven, so these ratios flatter or punish depending on the month chosen.

Valuation history, as reported

VIWho runs it and who owns it

Shayne Coplan is the chief executive and the company’s public face. He spoke for the firm on both the QCEX deal and the CFTC no-action position.³ In November 2024 the FBI searched his New York home as part of a Justice Department inquiry, and in July 2025 he said the CFTC and Justice Department had closed their probes. Neither agency commented, according to Reuters.¹³

Known holders include ICE (see above), Founders Fund, Vitalik Buterin and Polychain Capital, per TFN.⁸ The round reported in August 2026 is led by 1789 Capital, the venture firm partly associated with Donald Trump Jr., which was reported to put in about $300 million on top of around $200 million earlier.¹² A crypto-news article adds that Trump Jr. also advises Kalshi and that House Judiciary Committee Democrats are looking at 1789’s growth. No wrongdoing has been shown.¹² I note it because political ties can cut both ways for a business whose rules depend on regulators.

The company is young and its fortunes are tied to one founder-led team and one regulatory relationship, so a loss of either key people or the licence would matter more than at an older firm. That is my reading, not a reported fact. I could not find headcount, board makeup or the founder’s stake in the sources I opened, so I cannot judge how much control insiders have or what founders can take out.

VIIValuation: is the last price supported?

Equity value in US$ billions. Not a share price: a private company has none. Latest mark: primary round, post-money (press-reported, close unconfirmed).

What the last valuation assumes

At $21 billion, my model says a buyer needs about $3.4 billion of revenue in 2030 at a 14x multiple, or about $4.8 billion at 10x, to earn 20 percent a year after 15 percent dilution. In plain terms, revenue has to grow three to five times, regulators have to leave both venues alone, and Polymarket has to stay a clear number two or better against Kalshi. Those can happen together, but by my rough multiplication the odds are well under even.

Bear, base and bull

• Bear. 2030 revenue of $1.0 billion, flat from the June 2026 run-rate¹⁰, as regulation or competition cut volume. Terminal multiple 6x revenue (my assumption). Discount rate 20 percent a year for four years (my assumption for a private, regulation-exposed firm). Dilution 15 percent. Plus $1.5 billion net cash (my estimate, unverified). Result about $4.0 billion, from the model.
• Base. 2030 revenue of $3.2 billion, about 34 percent a year from $1.0 billion¹⁰, as the US exchange grows. Terminal multiple 10x revenue (my assumption), below Kalshi’s roughly 15x at its $22 billion mark⁸. Same 20 percent rate, 15 percent dilution and $1.5 billion cash. Result about $14.6 billion, which I round to 15.
• Bull. 2030 revenue of $6.0 billion as Polymarket keeps both venues and wins share. Terminal multiple 14x, near Kalshi’s mark at the $22 billion stage⁸. Same rate, dilution and cash. Result about $35.9 billion, rounded to 36.

Comparables used

Where I come down

The latest reported price of $21 billion is above my base of $15 billion and about 40 percent above it. It is near the upper part of my range between base and bull, and I could not tie it to audited numbers. The market may be right for reasons the data does not show. A strategic investor like ICE can pay for data distribution and optionality, not only for fees. Event-contract volume is growing quickly, as the October 2026 records on both venues show.¹⁴ A hot sector can also support high prices for a long time even when fundamentals lag. I cannot rule out that Polymarket’s offshore volume is larger than I can see.

What I cannot judge

I used no sourced public-company multiples because I could not retrieve any this session. My 6x, 10x and 14x terminal multiples are assumptions, with Kalshi’s private mark as the only anchor, so treat the range as wide. I could not read ICE’s quarterly report, Bloomberg’s original articles, the text of the CFTC amended order, or the company’s own fee page and accounts. I do not know current cash, share classes, preferences, or international volume. The $21 billion round may or may not have closed.

VIIIThe IPO

No IPO plan reported. I found no report of a listing plan, banker mandate or filing for Polymarket in the sources I opened. Kalshi’s chief executive reportedly said an IPO would not come before 2027, per CoinDesk, which gives a sense of sector timing.¹⁷ ICE, the NYSE owner, is both an investor and a possible listing venue, but I found no report linking the two on that point.

What to watch

• The final close, size and investor list of the $21 billion round
• Any CFTC enforcement action or settlement over the 2022 order
• Court rulings on state power over sports event contracts
• ICE’s filings: carrying value, gains and stake
• Polymarket US monthly volume against Kalshi
• Disclosed audited revenue, if any
• Reports of banker mandates or a confidential filing

IXWhat could go wrong

Regulatory risk is first. Reuters reported on 27 and 28 October 2026, citing two sources, that the CFTC is again examining whether Polymarket broke its 2022 settlement. It is looking at how the firm verifies where customers are, its US advertising, and the US platform’s onboarding and customer protections.¹³ Polymarket says it revamped its controls and bans the use of VPNs, which are tools that hide a user’s location. Neither the company nor the CFTC commented on the report. A probe is not a finding. Many do not lead to enforcement. But an adverse outcome could restrict the offshore exchange, which holds most of the volume, or put the US licence at risk.¹³

Second, the state-versus-federal fight. If courts decide states can bar sports contracts, a large share of volume is exposed, since sports were about 40 percent of volume in 2026.⁹ I could not verify the court record, so I cannot put odds on it.

Third, the revenue may not hold. The run-rate of just over $1 billion came six weeks after the US exchange opened, and during busy sports and election news.¹⁰ Volume is cyclical. Sacra’s global numbers show a peak in March 2026 of $10.5 billion and $8.9 billion in May, so it already fell once.⁹ Fees also invite competition, and Kalshi’s take rate is lower per Sacra.⁹

Fourth, what has to go right together. For the base case I need four things at once: regulators do not restrict the main venues, state challenges do not cut off sports, the US exchange keeps growing against a stronger rival, and fees hold. Each of these looks plausible alone. If I give each a rough 70 to 80 percent chance, which is my guess and not a data point, the four together land near 25 to 40 percent. That is why my base is below the latest price and my margin of safety is 25 percent below base.

Fifth, the owner’s view. A buyer of private stock gets a minority stake with little information and no easy exit. A stake is only worth what a later buyer, a listing or an acquirer pays, and the newest investors may hold senior rights that I cannot see. For the same dollar, a listed exchange operator with audited accounts and cash flow is a simpler alternative, though it would not have Polymarket’s growth. This is research, not advice.
