Distribution partnerships · Prediction markets

I work on the partnership
distribution side

of prediction markets.

Day to day: finding apps that already hold funded users, working out what it takes to integrate them, and how the terms should be structured. I write about the sector in public, and I track every deal that closes.

The map

Partnerships established, and still open.

Every closed deal shares one pattern: users who already stake money, a funded balance, and no new behaviour to teach. Below are the ones that signed — and the ones that fit the same profile and haven't yet.

Deal analysis

The most recent deals set the tone.

Sleeper × Kalshi

Feb 2026 Route A · Property registered as FCM

Sleeper Markets secured NFA approval as a Futures Commission Merchant, then launched in-app markets to 10M users two days before the Super Bowl.

What Kalshi got

  • $1B+ cleared in a single day — a record, up 2,700% year over year
  • $500M+ tied to the game, against $27M the prior Super Bowl
  • Best week in company history at $2.80B; Polymarket managed $55M on the same event
  • Distribution that cost no acquisition spend — users arrived funded and verified

What Sleeper got

  • A new revenue line on an audience it already owned
  • Year-round engagement on a product that is otherwise seasonal
  • Control of the customer relationship by holding the FCM licence itself
  • Differentiation against every competing fantasy app

The strategic read: Mansour said Kalshi was “the biggest brand of the Super Bowl without running a Super Bowl ad.” That is the whole argument for distribution over marketing, stated by the winner.

Players’ Lounge × ProphetX

Jul 2026 Route B · No registration required

Players’ Lounge holds no CFTC or NFA registration. Customers open accounts directly with ProphetX, which carries onboarding, KYC, execution and settlement. Weeks to launch instead of months.

What ProphetX got

  • An audience with $250M in wagers handled since 2016 — already staking money
  • +50% in users and assets across its first 30 days regulated
  • A repeatable template — more agreements signed before NFL season
  • Positioning as “the exchange behind the exchange” rather than a competitor for users

What Players’ Lounge got

  • Revenue with no licence, no capital and no compliance function
  • A share of commission rather than a fee to pay
  • Content that fills the gap between gaming sessions
  • Optionality — register later and take more, or stay light

The strategic read: no cash changed hands at signature. The property risked nothing and gained a revenue line; the exchange paid only out of volume it received. That alignment is why these close in weeks rather than quarters — and why the model will be copied.

The day job

My strategy for working a deal.

Track A · Technical

What the API actually allows

  • Read the partner's stack and scope API access, order routing and settlement flow
  • Work out what they can support today versus what needs building
  • Size the integration honestly — weeks or months, and who does the work
  • Sit with their engineers directly rather than relaying questions
Track B · Commercial

Whether the economics work

  • Choose the route: FCM registration or unregistered tech partner
  • Model the economics — commission split, funded-account value, payback
  • Negotiate the terms that decide durability, especially lifetime attribution
  • Map regulatory exposure: state eligibility, age gating, integrity requirements

Structure, distribution, and the plumbing underneath — from partner-program fee mechanics to what each exchange actually exposes through its API.

NEW Kalshi's API: 17 Endpoint Groups, What Can Be Built on Each, and Who's Already Doing It Went through every REST group Kalshi exposes — roughly 40 open endpoints, which need no account, and what a partner can actually build on each. Nine groups are open with no credentials at all. TechnicalPart 1 of 2 NEW Don't Want to Miss the Prediction Market Boom? Partner Programs and Fee Structures, Explained What it actually costs to start earning on each venue — Polymarket from a settings page, Crypto.com via a widget embed, FanDuel by application, Kalshi behind a CFTC licence. Four venues, four completely different barriers. Fee structuresPart 1 of 3 01 Why I Think Kalshi Is Quietly Becoming a Regulated Financial Exchange Argued Kalshi ends up as financial infrastructure, not a betting app — on the licence, the derivatives roadmap, the valuation multiple and institutional flow. Kalshi Pro shipped perps, margin and hedge-fund clearing four months later. Called itThesis · Part I 02 Is a Kalshi Contract a Derivative or a Bet? Nobody Actually Knows Argued the question is genuinely unresolved — the same contract ruled a protected swap in one circuit and unlicensed gambling in another, because the statute never contemplated it. The split is still live and widely expected to reach the Supreme Court. UnresolvedLegal · Part II 03 Last Week I Said Nobody Knew What Kalshi Is. This Monday, It Published Pro Read Kalshi Pro as the company answering its own question — a terminal, perpetual futures and institutional clearing are not the roadmap of a sportsbook. Courts still haven't ruled; Kalshi decided anyway. Called itThesis · Part III 04 Test, Partner, Dominate, Acquire: Robinhood's Four Moves Into Prediction Markets Reconstructed the playbook from public data: test on borrowed product, partner for the licence, become indispensable, then buy the exchange. Rothera now clears roughly $2B a month. PlaybookDistribution 05 Prediction Markets Can't Really Run Ads. I Think That's Their Advantage Argued the advertising constraint forces the category toward distribution partnerships instead of paid acquisition. Kalshi now powers six brokerages; ProphetX calls itself the exchange behind the exchange. ArgumentDistribution

If you're building the
distribution side, let's talk.

I'm most useful to exchanges that have a licence and need flow, and to platforms sitting on funded users with no idea the category exists. Happy to share what I've mapped either way.
