Top-Three Operator Worldwide" Is a £14,000m Revenue Floor. We Read the Filings.

£23,291 million.

That is the combined most-recent-filing revenue of the four English-market operators we hold on our desk's audit file. It is the answer to the question almost nobody asks when a new launch announces it will be a "top-three operator worldwide" — what number, on the public record, does that sentence have to clear?

When the press release crossed our desk announcing the former BetVictor chief executive's new venture, 21.com, with the stated ambition of becoming a "top-three operator worldwide," we did what we always do at this desk. We pulled the filings of the operators that currently occupy those slots. The marketing claim is one document. The filings are the other. The gap is where this piece lives.

A concession before the teardown begins. The iGaming market in 2024 is large enough, in principle, to support a new top-tier entrant. H2 Gambling Capital puts global iGaming gross gaming revenue at $94bn. Operators have been built from a standing start inside fifteen years — DraftKings was founded in 2012 and filed $4,770m in FY2024 revenue. The market is not closed. The route is not impossible.

The "top three" claim is something different. We walked it back through the public filings.

Methodology

This investigation is grounded in the most recent publicly filed annual reports and regulator-published enforcement notices for four operators that any reasonable definition of "top three worldwide" would put inside the contention set: Flutter Entertainment, Entain, Bet365 and DraftKings. We pulled FY2024 revenue, active user counts, regulated-market revenue percentages, tier-1 licence footprint and recent enforcement settlements from each operator's annual report and from the UK Gambling Commission public register. Flutter's revenue and segment data come from the Flutter investor results centre, verified 2025-03-04.

We do not hold 21.com's own filings on our desk. The operator is a new launch with no comparable public document set at our cutoff date. Every claim about what 21.com would have to accomplish to displace one of the four operators above is grounded in those four operators' own disclosures — not in inferences about 21.com itself. Where the data does not cover a claim, we say so. Where a comparison requires a figure we do not have, we omit the claim. The investigative weight here sits on what the existing top operators have on the public record, and what a new entrant would need to match.

Finding #1: The Revenue Floor Is Higher Than the Claim Implies

Flutter Entertainment filed FY2024 revenue of $14,048m. That is one operator, one fiscal year. The Entain plc Annual Report 2024 records group revenue of £4,833m across 27 brands and 28 million active customers. Bet365 — privately held, Coates family-controlled, registered in Stoke-on-Trent — filed FY2024 revenue of £3,388m through its Companies House filings. DraftKings filed $4,770m USD in FY2024 revenue, twelve years after founding.

If "top three worldwide" is measured by group revenue, the third slot sits somewhere around the $3.4bn–$4.8bn range depending on FX and how the question is framed. The first slot is currently $14bn. Whatever 21.com is at launch, it is not those numbers. Reaching them is not a sprint. PokerStars cost Flutter $12.2bn in the 2020 merger — the price of buying a global poker player base in a single transaction. The capital required to compress organic growth into a few reporting cycles is on the public record, and it is the size of a mid-cap acquisition, not a marketing budget.

There is a softer reading. By active jurisdictions. By a particular vertical. By GGR rather than reported revenue. We accept those readings exist. We note that the launch press release did not specify which one was meant. In the absence of specification, the most common reading — group revenue across the regulated estate — produces the floor above. The reader can pick another definition. The numbers in that definition will still be in the filings.

Finding #2: FanDuel Is the Reason Flutter's Number Is What It Is

This is the cross-reference any "top three worldwide" claim has to confront. Flutter's FY2024 US segment revenue was $6,180m. That single segment is larger than Entain's entire group revenue. Within that segment, FanDuel commands 43% of the US online sportsbook market, is live in 22 states, and contributed 44% of Flutter's total group revenue in FY2024. FanDuel held a 28.5% share of New Jersey's sportsbook market on the most recent NJDGE filings. The US online sports-betting market itself is sized at $13.7bn.

A new operator targeting "top three worldwide" in 2026 has two paths to dislodging Flutter: take meaningful US market share from FanDuel, or build a footprint elsewhere that exceeds FanDuel's contribution. The first path runs into the fact that Flutter completed its NYSE secondary listing on 2024-01-29 — capital was raised at scale against precisely the strategic position that makes FanDuel difficult to displace. The second path runs into the fact that 52% of global iGaming gross revenue sits in regulated markets, that the US is the largest of those, and that no operator without a US presence is in the current top three by revenue.

There is the Entain reading of the same problem. The BetMGM joint venture — Entain and MGM Resorts International, structured 50/50 — gives Entain exposure across 26 US states without owning the brand outright. A new entrant in 2026 does not have a comparable US JV on the public record yet. Until one exists and is filed, the US revenue gap between any new launch and Flutter is structural rather than competitive.

Finding #3: The Grey-Market Shortcut Doesn't Exist Anymore

Entain's FY2024 annual report records that 88% of group revenue now comes from regulated markets. The 12% that does not is the part the operator has been actively reducing. The reason that number moves the way it moves is on the public enforcement register, and the dollar amount is the kind of figure that ends careers.

In August 2022, the UKGC issued a £17m regulatory settlement to Ladbrokes Coral — Entain-owned brands — for what the regulator described as failure to carry out sufficient customer interactions with high-risk players, failure to adequately identify players showing signs of problem gambling, and AML controls inadequate for customers with unusual deposit patterns. In March 2023, the regulator fined the Sky Betting and Gaming licensee inside Flutter UKI £1.17m for social responsibility and AML failings. In December 2022, Bet365's Hillside licensee was fined £582,120. Entain entered a Deferred Prosecution Agreement with the UK CPS in December 2023 worth £585m, relating to the former Turkey-facing business of Headlong Limited — a subsidiary the group had already sold in 2017.

We flag the DPA specifically because the size of it is the implicit answer to the question every "top three worldwide" claim contains. What is the price of having grown through grey markets and then having to walk that growth back into compliance? £585m, six years after the divestiture, is one operator's answer on the record. The grey-market route is a route to the top of the leaderboard via the bottom of the regulator's docket. The cost has been documented.

Finding #4: 90 Million Registered Users Is the Mountain Behind the Numbers

Bet365's most recent filings put registered customers at approximately 90 million, across roughly 170 countries served. Entain's annual report records 28 million active customers across 27 brands. Flutter records 14.1 million active customers across an 18-brand portfolio. These are decade-plus user bases — built across boom periods in regulated-market expansion, through acquired brands (PokerStars, Ladbrokes, Coral, FanDuel), and through marketing budgets the size of which is not broken out at the line-item level in the filings we trust here.

The jurisdictional footprint adds to the mountain. The AGCO records 49 licensed iGaming operators in Ontario as of late 2024. The UKGC public register holds 268 active UK-licensed online operators. Germany's regulator, the GGL, enforces a cross-operator monthly deposit cap of €1,000 per user that tracks combined deposits across all German-licensed operators. That means revenue-per-user in Germany has a statutory ceiling that the operator cannot work around by adding a second brand. The room at the top of each regulated market is crowded. The ceiling on revenue-per-user in some of those markets is fixed by statute. Neither condition existed when Bet365 was building its 90-million user base through the 2000s and 2010s.

We are not saying a new operator cannot acquire users. We are saying "top three worldwide" requires a particular order of magnitude of user base that the four operators in our dataset have spent decades building, under regulatory conditions that have since materially tightened.

Where the Numbers Sit Right Now

The table is what "top three" looks like on the public record today. Any new entrant claiming the slot needs filings denominated in the same units. A serious attempt would be visible inside three to five reporting cycles.

What This Does NOT Prove

We do not have 21.com's own filings on our desk. We have the launch press claim and nothing else. The investigation above does not say 21.com will fail to reach the top three. It says the top three on the public record is a specific revenue range, user base order of magnitude, and licensing footprint, and that any claim to occupy one of those slots can be checked against the filings of the operators currently in them. When 21.com files something comparable, we will read it.

We also acknowledge that "top three" admits multiple definitions. By GGR rather than reported revenue, by a particular vertical, by registered users in a specific region, by jurisdictional count — each definition produces a different leaderboard. The founder may have a specific definition in mind that the press claim did not articulate. We can only walk back the claim against the most-cited public meaning of the phrase. The reader can pick another and we will rerun the maths.

The Takeaway

"Top three worldwide" on the public record is a $3.4bn–$14bn FY revenue band sitting on a multi-decade user base behind a tier-1 licensing wall — and the route to reaching it through grey markets has been documented in nine-figure settlements. The founder presumably already knows.

FAQ

What does "top three operator worldwide" actually translate to in 2026 filings?

On the public record, the third revenue slot among English-market operators currently sits between Bet365's £3,388m FY2024 revenue and DraftKings' $4,770m FY2024 revenue, depending on FX assumptions. The first slot is Flutter Entertainment at $14,048m. Any claim to be a "top three" operator is implicitly a claim to file revenue inside that band within a defined window. The 21.com launch press claim we are responding to did not specify the window or the measurement, which means the claim cannot yet be checked against a filing.

Why doesn't the grey-market route to scale work the way it used to?

Because the enforcement record now exists in writing on the UKGC public register and in court-published DPA documents. Entain agreed to a £585m DPA with the UK CPS in December 2023 over a Turkey-facing subsidiary sold in 2017 — meaning the regulator and prosecutor are willing to walk back operator conduct from six years prior. The Ladbrokes Coral £17m and Sky Betting and Gaming £1.17m settlements covered failings inside fully UK-licensed brands. The route is not closed. The price of taking it has been quantified.

How long did the current top operators actually take to get there?

Flutter, in the lineage that runs through Paddy Power Betfair to Flutter Entertainment, traces back to 1988. Bet365 was founded in 2000 by the Coates family in Stoke-on-Trent and remains privately held. Entain was incorporated in 2004. DraftKings — the youngest of the four — was founded in 2012 and reached $4,770m in FY2024 revenue twelve years later, listing on NASDAQ on 2020-04-24 and acquiring Jackpocket for $750m in 2024 to add a lottery vertical. Twelve years from incorporation to top-tier filing is the fastest grounded path we currently hold.

Does a new operator need US exposure to credibly claim "top three worldwide"?

On current revenue distribution, the US is the largest single iGaming and sports-betting market by a wide margin: $13.7bn in US online sports betting alone, contributing $6,180m to Flutter's group revenue via FanDuel and giving Flutter a structural lead over Entain. Entain itself reaches the US through the BetMGM JV — a 50/50 structure with MGM Resorts International announced in 2018 and live in 26 states. An operator targeting "top three" in 2026 without a US sportsbook brand, a US JV, or a credible roadmap to one is targeting at most second-tier on the existing revenue ladder.

What would 21.com actually need to file to make the top-three claim defensible?

A filed group revenue figure inside the £3bn–£5bn range at minimum, a regulated-markets revenue percentage in the upper bracket where Entain sits at 88%, an active user base in the tens of millions across multiple tier-1 jurisdictions (UKGC, MGA, AGCO, NJDGE) with the licences visible on each regulator's public register, and an enforcement record clean enough that the regulator-cost-of-growth ratio does not consume the revenue. Until any of those numbers exists on the public record under 21.com's name, the claim sits where every operator's pre-launch ambition sits — in the press release.
