STX Ontario Review 2026: The Only Betting Exchange

How We Checked STX

This review is built on primary sources only, and it comes with a caveat we will not bury: STX’s public website refuses every connection we could make to it, so more of this page rests on the operator’s app listing and its own archived documentation than we would like.

• We confirmed the brand, the operating company and the categories in the iGaming Ontario directory, and the category is the story here.
• We read the operator’s current App Store description, which is where STX explains its own model.
• We read STX’s own FAQ from a dated public archive, and every figure taken from it is labelled with that date.
• We pulled the app version, release date, size and rating from Apple and confirmed the Android build on Google Play.

Everything below is dated 9 September 2026, except where a 2024 archive is named as the source.

Is STX Legal in Ontario?

Yes. STX is listed in the iGaming Ontario directory under SportsX, LLC, and the operator states it is “licensed in the province of Ontario by Alcohol and Gaming Commission of Ontario to provide Internet Sports Betting Services”.

You must be 19 or older and physically in Ontario to transact, which the operator repeats in its FAQ and in its app listing.

The Only Betting Exchange on the Register

Here is what makes STX different from every other brand on this site, and it is a matter of record rather than opinion.

The iGaming Ontario directory lists each site by category – Casino, Sports Betting, Poker, Bingo and Betting Exchange. STX is listed under Sports Betting and Betting Exchange.

It is the only one of the 35 registered sportsbooks carrying that second category. Every other book on the register is a bookmaker; this one is a marketplace.

“Canada’s First Regulated Prediction Market”

That is the first line of STX’s own app listing, and it is worth unpacking rather than repeating.

We can confirm the narrow, checkable part: STX is the only site on the iGaming Ontario register carrying the Betting Exchange category, and it is registered here. Whether it was first in Canada is the operator’s claim, not our measurement.

The phrase itself matters more than the ranking. A prediction market prices an outcome by what participants will pay for it, rather than by what a trading room decides to offer – which is the same mechanism, under a different name, as the exchange model below.

How an Exchange Differs From a Sportsbook

The distinction is not marketing. It changes who you are betting against and where the operator’s money comes from.

At a bookmaker, the house sets the price, takes the other side, and builds a margin into every line. At an exchange, other players take the other side and the operator charges a fee for running the venue.

STX puts it in its own FAQ, in one line: “Am I trading against STX? No. We do not participate in the wager. Every wager you make will be with another user on the platform. STX acts as the fiduciary.”

That last row is the one experienced bettors will care about most. In the operator’s words: “Bet your size. No one is going to cut your limits because you win too often.”

Only Pinnacle’s Ontario book makes a comparable promise on this register, and it does so as a bookmaker rather than an exchange.

Contracts, Not Odds

STX prices in contracts rather than in decimal or American odds, which takes a moment to get used to.

Every market settles YES or NO. In the operator’s FAQ: “the wager is either worth $0 for NO or $100 for YES“. What you pay for a contract is what the market thinks the outcome is worth.

The 2026 app listing calls these “event contracts” and describes buying or selling them, which is the language of a prediction market rather than a betting slip.

The practical upside is that you can sell a position before the event ends, at whatever the book is paying: “Cash out all or part of your bet whenever you want, at whatever the market is paying right then.”

What STX Charges

This is where the picture is least current, and we would rather show you the gap than paper over it.

Those are two different fee models. A charge on winnings is not the same as a charge for crossing the spread, and the newer wording points to the second.

We cannot reconcile them, because the live fee page is behind the 403. What is consistent across both is the important half: you are not paying a bookmaker’s margin, and a losing position costs you nothing beyond the stake.

Before you fund an account here, ask support what the current fee is and how it is applied. It is the single number that decides whether an exchange beats a sportsbook for you.

What You Can Bet On

The markets are the mainstream North American slate, with the depth going into player props rather than into obscure leagues.

The operator names NFL, NBA, MLB, NHL and soccer, “with player props on every major slate”, plus spreads, totals and live markets that move during the game.

We could not count markets on a fixture or measure the spread between the best buy and sell prices, because that needs an account. On an exchange those two numbers matter more than anywhere else, and we are not going to estimate them.

Prices on an exchange differ in kind from a sportsbook’s: you are matched against another bettor rather than against the house, which is why the register lists STX under a category of its own rather than alongside the other 34.

Payments and Support

STX funded accounts by Interac and wire transfer when its FAQ was archived in 2024 – two methods, with no card option listed. Our Interac betting sites guide covers which Ontario books publish their limits up front, and the payment methods guide covers the rest.

Support and complaints both run by email, at contactus@stxapp.io and, for disputes, contactus@on.stxapp.ca. We found no live chat and no phone number.

A two-method cashier and an email-only support desk are thin by the standards of this register. Both figures come from a 2024 page, so treat them as the last documented position rather than today’s.

The STX App

STX is an app-first product, and that is not a criticism – it is how an order book is meant to be used.

Twenty-three ratings is a small sample and we will not oversell it. What the dates do show is a product being worked on: both builds shipped within days of this review.

Android Arrived After the Documentation

The 2024 FAQ answers the sign-up question with “Our product is currently available on iOS“, and tells you to download from the App Store.

Today there is an Android build, updated two days before this review. So the app has moved on while the written documentation has not, which is the same pattern as the fees.

Responsible Gambling and the 19+ Rule

The tools sit in a section STX calls Player Protection, and the asymmetry is the right way round.

Player Limits can be made more restrictive at any time, while a limit can “only increase after the associated timeframe has passed”. Cool Off starts at a minimum of one day and logs you straight out for the duration.

If you want your money back during a cool-off, the FAQ tells you to email support rather than leaving it stranded – a small thing, and better than silence.

One point of real credit: STX publishes an unusually long list of help resources, including ConnexOntario, Gamblers Anonymous Toronto, Gamtalk, Credit Canada and Talk Suicide Canada. Most books on this register publish one line. This one publishes seven, including services for debt and for crisis rather than gambling alone.

The two that stand out are Credit Canada and Talk Suicide Canada. Neither is a gambling service, and listing them is an acknowledgement of where gambling harm actually lands.

The archived footer also carries a Gaming Labs Certified mark, which is testing-house certification of the platform.

Final Verdict

STX is the most interesting product on the Ontario register and the hardest one to check. It is the province’s only registered betting exchange, it does not take the other side of your bet, and it says plainly that it will not cut your limits for winning.

What holds it back is not the model but the paperwork around it. The public site is closed to us, the published fee is two years old and no longer matches the app’s own wording, and support is one email address.

Overall we place STX at 3.5 out of 5 for Ontario bettors. The idea is the best on the register; the documentation around it is the least accessible we have met.

Who It Suits Today

STX suits a bettor who already understands exchanges: someone who wants to see the whole book, take a price rather than accept one, trade out at half-time, and not be limited for winning.

It suits you less if you want a familiar bet slip, a wide choice of payment methods, or the ability to read the terms and the fees before you register.

If you are new to exchanges, start small. Paying for a contract is not the same as staking on odds, and the difference is easiest to learn with money you can afford to lose.

STX FAQs

• Is STX legal in Ontario?

  Yes. STX is listed in the iGaming Ontario directory under SportsX, LLC, in the Sports Betting and Betting Exchange categories, and states it is licensed by the AGCO. You must be 19 or older and physically in Ontario to transact.

• What is a betting exchange?

  A marketplace where you bet against other users instead of the house. The price comes from an order book rather than from a bookmaker, and the operator earns a commission rather than a built-in margin on every line.

• Do you bet against STX itself?

  No. Its own FAQ states: We do not participate in the wager. Every wager you make will be with another user on the platform, with STX acting as the fiduciary that keeps play fair.

• What does STX charge?

  Its archived 2024 FAQ said up to 5% on winning settlements, with no fee on losses. Its 2026 app listing instead describes a small fee for taking liquidity. Ask support which applies before funding an account.

• Does STX have an app?

  Yes, on both platforms. The iOS app is rated 4.6 out of 5 from 23 ratings and was updated in September 2026. Android arrived later: the 2024 FAQ still says the product is iOS only.

• Can you cash out on STX?

  Yes, in full or in part, at whatever the market is paying at that moment. Because prices come from an order book, cashing out means selling your position rather than accepting a figure the house offers.

Alternatives to STX

No other registered Ontario site is an exchange, so there is no like-for-like swap. These two come closest on the things that draw people to one.

Pinnacle is the nearest match in spirit: a bookmaker built on low margins that publishes a policy of not restricting winning accounts, though it has no cash out and no app.

TonyBet’s Ontario board gives you the deepest conventional board on the register, with cash out including between the legs of a multiple, and it publishes every cashier number on a public page.

No other registered site holds an exchange licence, so every alternative is a conventional book. The closest in spirit is Pinnacle, which charges no commission on winnings and publishes a policy of not restricting the accounts that beat it.
