Crypto narratives usually arrive as a promise. This one arrived as a revenue line.
At Robinhood, prediction markets generated $156 million in the second quarter of 2026 against $100 million from crypto — event contracts out-earned the entire crypto business at a platform that has been a major crypto venue for years. That single comparison explains why every board in the sector is now paying attention.
The growth, measured
Metric | Figure |
|---|---|
Q2 2026 sector volume | Around $111 billion, representing roughly 1,764% year-on-year growth. |
2025 full year | Volumes grew nearly fourfold sequentially to around $64 billion. |
2026 run rate | On pace to exceed $325 billion, with some analysts projecting the sector quadrupling to around $240 billion for the year and reaching beyond $1.1 trillion by 2030. |
Monthly comparison | March 2026 closed at roughly $25.7 billion — an almost thirteenfold increase on the $2 billion recorded in March 2025. |
Weekly peak activity | Weekly notional volume reached around $12.1 billion, with more than 341,000 active markets across platforms. |
Open interest | Sector open interest passed $1.11 billion on 1 May 2026, with Kalshi at roughly $630 million and Polymarket around $450 million — together about 98% of the total. |
Single-event scale | Jefferies reported the World Cup generated around $20 billion in prediction volume. Kalshi saw more than $1 billion on Super Bowl Sunday alone. |
A category that did $2 billion in a month last year did $25.7 billion in the same month this year. Crypto has not produced a growth curve like that since 2021.
Who is actually buying — the real signal
Volume can be manufactured. Capital commitments from institutions with reputational exposure are harder to fake, and the past year has produced a land grab.
Institution | Commitment |
|---|---|
Coatue Management | Led a round of over $1 billion into Kalshi in March 2026 at a $22 billion valuation — roughly double its December 2025 valuation of $11 billion. Kalshi was reported at around a $1.5 billion annual revenue run rate. |
Intercontinental Exchange | The parent of the New York Stock Exchange completed a $2 billion commitment to Polymarket. Polymarket has separately been reported as raising around $1 billion at a $20 billion-plus valuation. |
DraftKings | Volumes reportedly quintupled between April and July, with around 600,000 users, an $11 billion annualised figure and a reported $200–300 million investment. |
Coinbase | Reported at around a $100 million run rate. |
Robinhood, Crypto.com, Fanatics, Meta | All entered or expanded. Fanatics launched across 24 states; Crypto.com posted $629 million in March, up 58.5% month on month. |
Kalshi and Polymarket jointly | The CEOs of the two arch-rivals jointly backed a $35 million venture fund targeting the same sector. |
When the owner of the New York Stock Exchange puts $2 billion into a prediction market, the category has stopped being a crypto-native experiment. Kalshi also secured a licence to offer margin trading to institutional clients in March, which tells you where it thinks the growth is: institutional money, not retail.
Why it won where crypto narratives usually stall
Four reasons, and they compound.
It has a use case people already understand. Explaining a prediction market takes one sentence. Explaining why a rollup needs its own token takes twenty, and most people stop listening at three.
It generates revenue immediately. Fees on volume, from day one, with no token emissions subsidising activity. Polymarket collected around $29 million in fees in April alone despite trailing Kalshi in volume.
There is a regulated path. Kalshi operates as a CFTC-registered designated contract market. That is a recognisable, licensable structure that an institutional allocator can underwrite — unlike most of what crypto has offered.
The demand turned out to be additive. This is the finding that changed the industry’s posture.
The 1% overlap
Research indicates roughly 1% customer overlap between sportsbook users and prediction market users.
Read that carefully, because it inverts the obvious assumption. Prediction markets were expected to cannibalise sports betting. Instead they appear to be reaching a substantially different audience — which is why DraftKings went all-in with a reported $200–300 million investment rather than lobbying to shut the category down.
For an incumbent operator, a product that grows the addressable market rather than splitting it is not a threat to be litigated. It is a segment to be acquired.
The information function is real — and being used
There is a genuine argument underneath the speculation, and it deserves to be stated rather than dismissed.
Prediction markets have demonstrated the ability to surface more precise event probabilities than polls or expert forecasts, on the reasoning that monetary skin in the game produces better calibration in real time.
That function is now being consumed institutionally. TS Imagine has been embedding prediction market probabilities into institutional risk workflows — which is the point at which a market stops being entertainment and becomes a data product.
It shows up in market commentary too. When analysts write that traders assign a 32% probability to Bitcoin reaching $100,000 this year, that number comes from a prediction market. It is now a routinely cited input, quoted the way implied volatility or futures pricing is quoted.
The problems, stated plainly
This is where a promotional version of this article would stop. There are four serious issues.
WHAT THE GROWTH STORY OMITS Concentration in sports. Sports has accounted for between roughly 76% and 90% of trading volume depending on the week and platform. The information-aggregation argument rests on elections and economics; the revenue rests on games. Legal exposure. The New York Attorney General has sued Kalshi in an action reported at $36 billion, and multiple state gaming regulators have taken enforcement action. Federal courts have ruled both ways on whether state gambling law is preempted. Platform concentration. Kalshi and Polymarket hold roughly 98% of sector open interest. Kalshi alone has reached over 90% weekly market share. This is a duopoly, not an ecosystem. Product drift towards gambling. Operators are adding parlay-style contracts and multi-leg products — which move the offering closer to a sportsbook, not further from one, at exactly the moment the legal distinction matters most. |
That last point is the one worth watching. Every step towards parlays strengthens the argument of the state regulators arguing this is wagering in a different wrapper. The industry is expanding into the products most likely to lose it the legal fight it depends on.
Is this even a crypto narrative?
Here is the question the sector avoids asking itself.
Kalshi — the largest platform by volume and market share — is a CFTC-regulated designated contract market. It is a derivatives exchange. Its growth has come from sports, its capital from Coatue and traditional finance, its ambitions from institutional margin trading. There is very little about it that is crypto.
Polymarket is on-chain, settles in stablecoins, and is genuinely crypto-native in architecture. But its largest backer is the owner of the New York Stock Exchange.
Prediction markets became the crypto narrative at roughly the moment they stopped needing crypto. That is either the sector’s greatest success or a sign the value is leaving.
Both readings are defensible. The optimistic one is that crypto incubated a product that reached mainstream scale — which is what infrastructure is supposed to do, and stablecoins tell a similar story. The pessimistic one is that the value accrued to a derivatives exchange, a stock exchange operator and a sportsbook, none of which needed a token.
What to watch
Volume composition. If non-sports categories grow as a share of total volume, the information-market thesis strengthens and the legal risk falls. If parlays lead growth, the opposite.
The New York litigation and the broader preemption question. With federal courts split, this is heading somewhere higher, and the outcome is existential for the US business.
Whether the duopoly cracks. Ninety-eight percent of open interest in two venues is fragile to a regulatory event affecting either one.
Institutional data adoption. If more risk platforms embed prediction market probabilities, the category acquires a revenue stream independent of trading volume.
Whether the 1% overlap holds as the category scales. If it converges with sportsbook users, the additive-demand argument weakens and incumbents’ posture may change.
The bottom line
Prediction markets became the dominant narrative because they did what crypto narratives usually promise and rarely deliver: real users, real revenue, a licensable structure, and growth measured in multiples rather than roadmaps. A sector that traded $2 billion in a month last March traded $25.7 billion this March.
But the honest reading of why it worked is uncomfortable for the industry claiming it. The winning platform is a regulated derivatives exchange, the money came from Wall Street, the volume comes from sports, and the legal foundation is contested in courts that have ruled both ways.
It is the most successful thing to emerge from crypto in years, and it is succeeding by looking as little like crypto as possible.
