Is Kalshi Peer To Peer? Who Is Actually On The Other Side
Yes, Kalshi is peer to peer: the exchange matches buyers against sellers and there is no house taking your action, so Kalshi does not win when you lose. There is also a second fact that belongs in the same breath: an affiliated firm called Kalshi Trading may be quoting the very market you are trading, and its stated business purpose, in Kalshi's own rulebook, is profitability. Most pages answering this question give you one of those facts and bury the other. This one holds both up to the light, because both are true, both are sourced, and the honest answer to "who is on the other side of my order" runs through the second one. By the end you will also know what the federal regulator thinks of that arrangement, what it has proposed to do about it, and, the most interesting part, why it decided not to simply ban it.
The Quick Answer
Kalshi is peer to peer at the exchange level. KalshiEX, the CFTC-regulated exchange, matches your order against another participant's and does not take the other side itself, so there is no house betting against you. The other participant, though, can be an ordinary user, a professional market maker, or Kalshi Trading, a firm affiliated with the exchange whose job includes quoting prices in Kalshi's markets. The CFTC has proposed, not enacted, rules to police that structure across the whole industry, at least six exchanges run some version of it, and the details of what was proposed and why are below.
Peer To Peer Is True Of The Exchange
Start with the claim itself, because it is real. On a sportsbook, the operator sets a price, takes your bet, and profits when you lose; the counterparty is the house by construction. Kalshi is built differently. It is a betting exchange in structure: every contract has a Yes side and a No side, both held by market participants, and the exchange's software matches one against the other. When your contract settles at $1, the dollar comes from whoever held the opposite side, not from Kalshi. The exchange earns fees on trades either way, which is a different business model from needing you to lose — we walk through that distinction properly in an exchange is not a sportsbook.
So when Kalshi says there is no house, that is accurate as a statement about KalshiEX, the exchange entity. Hold on to that phrase, "the exchange entity," because the rest of this page turns on it.
SO Who Is Actually On The Other Side?
Three kinds of participants can be holding the opposite side of your contract.
The first is another user like you, someone who simply disagrees about the outcome. The second is an independent market maker, a professional firm that continuously posts both Yes and No prices and earns the gap between them; that role is a normal, necessary part of every exchange, and our explainer on market makers covers why a book without them is barely usable.
The third is the one this page exists for: Kalshi Trading, a firm affiliated with the exchange itself. Per Sportico's reporting by Dan Bernstein, Kalshi's own rulebook says Kalshi Trading's "business purpose is profitability," and that providing liquidity is "part" of that model. Kalshi does not disclose how much revenue Kalshi Trading generates or which markets it participates in, so neither you nor we can say whether it is on the other side of any particular order. What is on the record is thin and worth stating precisely: co-founder Luana Lopes Lara wrote on X in November that Kalshi Trading was not profitable at that time.
Put the two halves together and the honest answer takes one sentence: the exchange has no house, and an affiliated firm run for profit may still be quoting the market you are trading. That is not an accusation. It is a structure, and it is the structure a regulator has now formally noticed.
This Is An Industry Structure, Not A Kalshi Story
Here is where a lazy version of this page would go wrong, so let us be direct: Kalshi is not being singled out, and if you finish this article thinking only Kalshi does this, you have been misled. The CFTC says it is aware of at least six exchanges that permit affiliated principal trading. Named or reported among them: Kalshi with Kalshi Trading; Novig, whose affiliated firm Manhattan Athletic Group trades on its Ludlow Exchange; DraftKings; Crypto.com; Polymarket; and Susquehanna, which holds 45% of the Rothera exchange in a joint venture with Robinhood. Far from hiding the practice, DraftKings urged the CFTC to "take a permissive approach to vertical integration" and called affiliated trading "even more compelling" than trading on independent platforms.
One disclosure of our own belongs right here, next to those names rather than in a footer: we have no affiliate or commercial relationship with Kalshi, but we do carry sign-up offers for some other prediction-market and betting platforms, including some named in this paragraph. Read anything we write comparing venues with that incentive in mind.
What The CFTC Has Actually Proposed
Now the news itself, sized exactly to what the sourcing supports. Sportico's piece, "Prediction Market Affiliated Trading Arm Rules Proposal, Explained," reports a CFTC notice of proposed rulemaking posted to the Federal Register, opening a 60-day comment period that closes October 5. Read those words carefully: it is a proposal. It is not a rule, not law, and not in force; the CFTC is not obliged to adopt any of it, and even after a final version is adopted there is a further 30 to 60 days before anything takes effect. Any page telling you the CFTC "has banned" or "now requires" anything here is wrong on the verb.
What the agency has proposed, stated as proposals:
- Last Priority In The Queue. Affiliates' resting orders would go to the back of the line at every price point, even if the affiliate got there first.
- Continuous Two-Sided Quotes. Affiliates would have to post both Yes and No prices at all times, earning only the gap between them, rather than picking spots to take one side.
- No Home-Field Advantages. No fee discounts and no latency advantage over other participants.
- Real Separation. Separate software, separate staff, separate office space from the exchange.
- Plain Disclosure. The app would have to identify the affiliate alongside every market it trades, in "plain language reasonably understandable to a non-specialist."
- Outside Eyes. Independent third-party surveillance of affiliate trading, with periodic reports to the CFTC.
One exemption is worth a line, because it is where the money is: the two-sided quoting requirement would not apply to parlays, which execute through a request-for-quote mechanism rather than a standing order book. Sportico notes parlays make up more than 30% of volume at some exchanges and are the most reliable revenue stream market makers have.
A Worked Example: Your Order And The Affiliate's
To see what the queue-priority proposal changes, picture a market where you and an affiliate both want to buy Yes at 60¢. Today, orders rest in a queue and fill in the order they arrived: if the affiliate posted its 60¢ bid before you posted yours, the next seller at 60¢ trades with the affiliate, and you keep waiting. Under the proposal, the affiliate goes behind you at that price no matter who arrived first. Every seller who comes through fills your order before the affiliate's. The affiliate still gets to quote, still earns the gap between its Yes and No prices, but it can no longer stand in front of you at your own price. That is the shape of the whole proposal in one rule: the affiliate may make the market, but it must eat last.
Why The Regulator Chose To Limit, Not Ban
This is the part a suspicious reader should sit with, because it explains the whole design. The CFTC did not propose banning affiliated trading arms. It says an outright prohibition would be "the most disruptive" option and might leave markets too thin for users to get in or out anywhere near a reasonable price. Remember the market makers from earlier: without someone continuously quoting both sides, a peer-to-peer book is an empty room, and liquidity is the thing that decides whether you can trade at all. Kill the affiliates and some of these markets may simply stop functioning; let them run loose and the exchange is refereeing a game its own family member is playing in.
The agency said that second part itself, and its framing is worth quoting: "[An] exchange's self-regulatory functions run directly against its commercial interest in the affiliate's trading." That sentence is the entire issue in a single breath. The proposal is an attempt to keep the liquidity while caging the conflict, and whether the final rule lands there, somewhere stricter, or nowhere at all is exactly what the comment period will fight over.
What You Can And Cannot Know Today
Zoom back out to the question you searched. Is Kalshi peer to peer? Yes: the exchange matches participant against participant and takes no side, which also means Kalshi the exchange earns its money from fees rather than your losses — how the exchange itself earns on every trade is its own subject and we keep it on its own page. Is there a house? No. Might a profit-seeking firm affiliated with the exchange be on the other side of your specific order? Possibly, and here is the honest boundary: Kalshi does not disclose which markets Kalshi Trading participates in, so nobody outside the company can tell you whether it was your counterparty, and you should distrust any page that claims otherwise in either direction. What you can know is the structure, the regulator's stated concern, and the proposed remedies, all of which are public. For what it is worth, Kalshi remains a CFTC-regulated exchange with broad, state-specific availability under federal oversight, and the regulation question has its own full treatment in is Kalshi legit.
We come at this with our own skin in the game, so take the disclosure plainly: Stokastic trades these markets and holds positions in them, and our public log of how these markets work is a record of a strategy we are not yet claiming works — every position in it is graded against the market's written settlement rule once a contract resolves Yes or No, wins and losses alike. Trading them has a shape worth respecting before you touch it: selling an unlikely outcome collects a small premium while risking most of a dollar, and roughly speaking one loss erases the premiums from about 14 wins, which makes position sizing the whole game.
Is Kalshi Peer To Peer FAQ
Who am I betting against on Kalshi? Another market participant: an ordinary user who disagrees with you, an independent market maker quoting both sides, or possibly Kalshi Trading, the exchange's affiliated trading firm. Never Kalshi the exchange itself, which only matches orders and collects fees.
Does Kalshi have a house? No. The exchange takes no side of any trade and does not profit when you lose. The nearest thing to a house is Kalshi Trading, an affiliated firm that quotes markets for profit — but it is a participant that can win or lose on its positions, not a counterparty built into every bet the way a sportsbook is.
What is Kalshi Trading? A firm affiliated with Kalshi that trades on the exchange, providing liquidity as, per Kalshi's rulebook, "part" of a business whose stated purpose is profitability. Kalshi does not disclose its revenue or which markets it trades, and a co-founder said in November it was not profitable at that time.
Who makes money on Kalshi? The exchange earns trading fees. Market makers, including affiliated ones, aim to earn the gap between Yes and No prices. Traders make money when they exit for more than they paid, minus fees — whether by selling the contract to another participant before settlement or by holding it through a result that settles their way.
Is Kalshi peer to peer betting or trading? Structurally it is peer-to-peer trading in CFTC-regulated event contracts: the mechanics are an order book and matched counterparties, the same architecture as a financial exchange. Whether you call the activity betting or trading is a fair fight, but the plumbing is an exchange, not a book.
Did the CFTC ban affiliated trading firms like Kalshi Trading? No. It proposed rules — queue priority, mandatory two-sided quoting, separation, disclosure, outside surveillance — in a notice with a comment period closing October 5. A proposal is not a rule, the agency may adopt none of it, and nothing takes effect until 30 to 60 days after any final version.
The Answer Worth Keeping
The peer-to-peer claim survives scrutiny; it just needs its second sentence attached: no house, and a family member at the table whose hands a regulator is deciding how tightly to bind. The practical thing to watch once the comment period closes October 5 is which two proposals survive, because they would change what you can actually see. If the queue rule makes it, the affiliate quoting your market waits behind you at your own price; if the disclosure rule makes it, the app has to name that affiliate beside every market it trades. Either would move a fact from the category this page calls unknowable into plain sight, and that migration, not any headline, is how you will know whether this proposal grew teeth.

Disclosure and fine print. Stokastic trades Kalshi weather markets and holds positions in them; where a settled position is described, we were the seller. We have no affiliate or commercial relationship with Kalshi. We do carry sign-up offers for some other prediction-market and betting platforms, including some named on this page, and comparisons should be read with that incentive in mind. Kalshi contracts are CFTC-regulated event derivatives traded on a designated contract market, not sportsbook wagers, and a position can lose its full value; selling an unlikely outcome collects a small premium and risks most of a dollar, and one losing sale can hand back the premiums from about 14 winning ones. 18+, available where Kalshi operates; eligibility and availability are state-specific and change. Nothing on this page is trading advice, a pick, a play, or a recommendation to enter any market, and no price shown here is a live quote.
