Your platform model
Four choices drive most of the legal result. Directional risk bands, not a computation of legal status in identified jurisdictions.
What is driving your result
Which states are which? That mapping, applied to your exact rules, fee language, and funds flow, is the deliverable of a signed state-by-state legal opinion. The counts above show the shape of your footprint; the schedule of named jurisdictions, the conditions per state, and a processor-grade opinion letter are the $1,500 comprehensive engagement.
The five questions that decide your footprint
These are the levers behind the numbers above, in the order they usually kill or save a launch.
1. Is your cut a service fee or a rake?The highest-impact structural choice on the platform
When both contestants fund the prize and the operator deducts a percentage of the pooled entries, several states read the operator's role as raking wagers, selling pools, or acting as a paid custodian of stakes, and those offenses do not care that the underlying game is pure skill. A separately stated, fixed, outcome-independent per-player fee, with the winner receiving 100 percent of the combined entries, is the structure that keeps the operator outside the bet.
2. Do the players' own entry fees make it a bet?The entry-fee doctrine and its limits, in plain language
The classic rule (Las Vegas Hacienda v. Gibson and its progeny) is that an entry fee paid unconditionally to an operator who does not compete for the prize is not a bet. But that doctrine has a catch founders almost never see: it works cleanly when the operator funds the purse. When two players fund the prize with their own equal stakes, some states recharacterize the match as wagering between the players, no matter how skillful the game. Whether a state has an express exception for prizes to the actual contestants (22 jurisdictions have some version of one on my current record) is often the whole ballgame.
3. Does an operator-side offense reach you even if players are legal?Pool-selling, bookmaking, custodian-of-stakes, and internet-site statutes
The least intuitive result in this field: statutes that never mention the players can still criminalize the platform. Pool-selling and bookmaking definitions with no chance element, paid custodian-of-stakes provisions, and internet-gambling statutes that expressly cover games of skill can each reach the operator's business model directly. On my current record, materially adverse operator-side structures drive most of the 20 excluded jurisdictions, and 27 jurisdictions have some form of staking-on-skill-contest prohibition that must be analyzed against the contestants' own entry fees.
4. Who holds the money?Custody, money transmission, and the chargeback story
If player deposits settle into the operator's own account with an internal ledger, two independent problems appear: custodian-of-stakes offenses in the gambling codes, and state money-transmitter licensing for holding and transmitting third-party funds. Custody with a licensed provider or sponsor bank, with the platform transmitting only objectively determined result instructions, mitigates both and is what processor underwriting teams increasingly expect to see documented.
5. Can you actually keep excluded states out?Whitelist-only activation and per-contest geolocation
A footprint is only as good as its enforcement. Underwriting-grade programs use an affirmative server-side whitelist (everything blocked by default), a device-level geolocation check immediately before every paid contest for every participant, VPN and spoofing detection, and logging. A billing address or a checkbox is not geolocation. And one more trap: geoblocking customers does not solve the operator's own home-state exposure, which is a separate analysis.
