I\u2019ve traded on both for about a year now, so here\u2019s the version that skips the marketing comparison tables. The short version: they\u2019re not interchangeable, and which one you can even use often gets decided for you by where you\u00a0live.<\/p>\n
The fee structures aren\u2019t even measured the same way. A standard sportsbook prices in roughly 5.3% margin on a typical two-way line (1.95\/1.85 odds). Kalshi charges per contract instead\u200a\u2014\u200aa cent or two depending on price, no flat percentage. The terminal I use on Polymarket\u2019s liquidity charges a flat 1% of volume. Three different units, which makes \u201cwhich is cheaper\u201d depend entirely on how you trade, not just which platform you\u00a0pick.<\/p>\n
Kalshi is a CFTC-regulated Designated Contract Market\u200a\u2014\u200aa federally regulated exchange, which is exactly why it\u2019s legal in states like Texas where traditional sportsbooks aren\u2019t. Polymarket isn\u2019t CFTC-registered the same way, which is part of why its US access situation is closer to \u201crestricted\u201d than Kalshi\u2019s \u201cregulated and\u00a0open.\u201d<\/p>\n
That regulatory gap shows up in practice as two different products with overlapping goals. Kalshi\u2019s federal registration means it can operate openly across most US states without the geoblocking Polymarket applies. Polymarket\u2019s advantage runs the other direction\u200a\u2014\u200adeeper liquidity specifically in sports and esports categories, built up over a longer operating history in that niche, even without the same US regulatory clearance.<\/p>\n
Kalshi fees run roughly $0.01\u2013$0.02 per contract depending on where the price sits, and the charge doesn\u2019t change by which state you\u2019re trading from. For high-volume, low-price trades this adds up differently than a percentage-of-volume model\u200a\u2014\u200aworth actually running the math for your own trading pattern rather than assuming one fee structure is universally cheaper.<\/p>\n
Run your own trade volume through both fee structures before picking one\u200a\u2014\u200aa cents-per-contract model and a percentage-of-volume model cross over at different points depending on contract price and size. There\u2019s no single answer that holds for every trader; the comparison only means something once you plug in your own\u00a0numbers.<\/p>\n
Robinhood has moved into event contracts too, layering prediction markets onto an app most people already have for stocks. It\u2019s worth knowing about as a comparison point\u200a\u2014\u200aone more sign this category isn\u2019t a niche experiment anymore, it\u2019s attracting mainstream brokerages, not just crypto-native platforms.<\/p>\n
\u201cBest\u201d depends entirely on what you\u2019re optimizing for. Regulatory clarity in the US points toward Kalshi. Sports and esports market depth is where a terminal built on Polymarket\u2019s liquidity\u200a\u2014\u200alike the one I use\u200a\u2014\u200atends to have the edge, since that\u2019s specifically what it\u2019s built around rather than being one category among many alongside politics, economics, and\u00a0culture.<\/p>\n
Anyone answering \u201cwhich is best\u201d without asking what you\u2019re trading is skipping the part of the question that actually determines the\u00a0answer.<\/p>\n
An app being polished doesn\u2019t tell you about liquidity depth in the specific category you actually trade. A clean interface with a thin order book in your market of interest is worse than a rougher one with real volume behind it\u200a\u2014\u200acheck the book before judging the\u00a0app.<\/p>\n
DraftKings, a sportsbook by origin, has been moving into prediction-market-style contracts too\u200a\u2014\u200athe reverse direction from Kalshi and Polymarket, which started as exchanges and are picking up sports coverage. Worth watching which direction the category consolidates toward.<\/p>\n
Kalshi is the most-discussed. Robinhood and DraftKings are newer entrants approaching from different starting points\u200a\u2014\u200aa brokerage and a sportsbook respectively. None of them are identical products; they\u2019re solving overlapping but not identical problems, and lumping them together in one \u201cbest of\u201d list obscures more than it explains.<\/p>\n
Picking between them isn\u2019t really about finding \u201cthe winner\u201d\u200a\u2014\u200ait\u2019s about matching the regulatory situation and category depth to what you\u2019re actually trying to trade. Someone focused on US election markets has different priorities than someone focused on NFL game outcomes, and the right platform for one isn\u2019t automatically right for the\u00a0other.<\/p>\n
If Kalshi doesn\u2019t cover a market you want, or you\u2019re outside its accessible regions, a terminal on Polymarket\u2019s liquidity is the alternative\u200a\u2014\u200aspecifically strong on sports and esports coverage rather than the broader mixed-category approach Kalshi\u00a0takes.<\/p>\n
Canada\u2019s situation is easy to get wrong. Wealthsimple, a major Canadian brokerage, got regulatory approval to offer event contracts to Canadian users\u200a\u2014\u200abut sports was explicitly excluded from that approval. That\u2019s the detail most coverage skips: Canadians can access some Kalshi-style event contracts through Wealthsimple, just not sports\u00a0ones.<\/p>\n
For sports specifically, that gap is exactly what a sports-focused terminal fills. It\u2019s a distinction worth being precise about, because a Canadian reader searching \u201cKalshi Canada\u201d is likely to land on coverage that talks about event contracts generally without mentioning that the one category they probably care about\u200a\u2014\u200asports\u200a\u2014\u200aisn\u2019t part of what\u2019s currently permitted through that specific\u00a0channel.<\/p>\n

overdog.bet<\/a> is what I use for sports and esports specifically. My trade history sits on the proof page\u200a\u2014\u200apublic.<\/p>\n Is Kalshi legal in Texas? Yes\u200a\u2014\u200aKalshi is a CFTC-regulated federal exchange, which puts it outside Texas gambling law entirely, unlike a state-licensed sportsbook.<\/p>\n Is Kalshi legal? Legal federally as a CFTC-regulated exchange, available in most US states. A handful of states have pushed back on specific contract categories, so availability isn\u2019t perfectly uniform everywhere.<\/p>\n Is Kalshi legal in Canada? Not directly as Kalshi\u200a\u2014\u200abut Wealthsimple offers similar event contracts under its own regulatory approval, with sports specifically excluded from what\u2019s currently permitted.<\/p>\n Responsible gambling isn\u2019t a line to skip. If trading stops being a deliberate decision and starts being a way to cover a budget gap, that\u2019s a reason to pause, not size\u00a0up.<\/p>\n Kalshi vs Polymarket 2026: Fees, Liquidity, Legality and Which You Can Actually Use<\/a> was originally published in Coinmonks<\/a> on Medium, where people are continuing the conversation by highlighting and responding to this story.<\/p>","protected":false},"excerpt":{"rendered":" I\u2019ve traded on both for about a year now, so here\u2019s the version that skips the marketing comparison tables.
