The Global Prediction Markets Race Has Begun.
$31.2 billion in a single month. ~300× growth since early 2024. Kalshi is now valued at $22 billion. The US market is effectively locked. Here is where the real operator opportunity is.
June set a new record. The trend line is steeper than the headline
Prediction markets hit over $50 billion in combined volume in June 2026, a new monthly record up 75% from May, driven by the FIFA World Cup. The entire year 2025 produced $63.5 billion in total volume. June 2026 alone eclipsed that full annual pace. Since early 2024, the category has grown approximately 300 times over.
The platform picture is more concentrated than the total suggests. Kalshi holds $33 billion (66% share) in June, its highest absolute figure and its widest margin over Polymarket, which posted $14 billion (28%). Rothera, Robinhood's venue, added roughly $2 billion (4%). The remainder is fragmented across smaller platforms.
One number operators should note: Kalshi's annualized revenue run rate crossed $1.5 billion, driven almost entirely by sports volume. That makes it one of the fastest growing revenue lines in financial technology, and it still has no licensed local competitor in any market outside the US.

The platforms that defined June
The most consequential development this month is not the volume record. It is who is doubling down in the US, and why that makes every other market more open, not less.
Surpassed FanDuel's parent Flutter in valuation. Now approved for institutional margin trading. Publicly pursuing the "Robinhoods of each major country" internationally, acknowledging that markets outside the US require local partners to access them.
Both incumbents are guiding $200–300 million each into prediction market app buildouts for 2026. They hold the US user base, the licenses, and the marketing infrastructure. The entry window for a US challenger is closing fast.
Crossed one million prediction market customers, then went further: acquired LedgerX (a CFTC licensed derivatives exchange) with Susquehanna, moving from Kalshi distribution partner to direct competitor with its own clearinghouse. The fastest growing revenue line is now vertically integrated.
All three launched prediction market products as a layer on existing platforms, not as new apps. The same architectural choice made by every major entrant: add a new trading vertical on top of an existing user base. Combined, these platforms reach hundreds of millions of users in exactly the markets Shift operates in.
Mark Zuckerberg announced Meta is building a standalone prediction market app (codenamed Arena). It will use Llama to auto-generate questions from trending topics, launching with a play-money model. Meta has not ruled out a real-money platform. With 3+ billion monthly active users, the entry signal is clear: prediction markets are moving from fintech niche to mainstream consumer product.
Every major entrant kept the same brand, the same users, and added prediction markets as a new revenue vertical on top. For operators outside the US, this same architecture is available, and the local infrastructure advantage is yours.
Sports is the engine and it maps to the traders you already have
Sports contracts now account for 89% of Kalshi's 2025 fee revenue. In June 2026, Kalshi posted $10.4 billion in sports volume versus $174 million for elections, a 60× ratio. The 2024 election was a spike in a fundamentally sports-driven product. Kalshi is a sports trading business with a diversified category layer on top.
The practical implication for operators: the sports prediction market user is the active trader you already have: someone with a short time horizon who already trades macro data releases, crypto events, and FX moves. Prediction markets formalize that behavior into a structured, monetizable product without a new acquisition budget.
The World Cup running through July is the clearest near term catalyst. Prediction market volume tied to the tournament is projected at $2.5 billion, a concentrated window of activity in the sports vertical already proven at scale. Operators with the product live during the final rounds capture the spike. Those without will watch their users find it elsewhere.
The longer trend: open interest in finance and macro markets grew 7× across 2025. Fed decisions, inflation prints, and jobs reports are becoming consistent recurring volume drivers, distinct from the event driven spikes of 2024. This is what a maturing category looks like.
The biggest opportunity is in markets the current platforms don't serve
Every platform in the June leaderboard was built for a dollarised, English first user. None holds a local license for Africa. None has local payment rails in Southeast Asia. None is regulated for MENA. The demand in those regions routes today to offshore venues that no local operator monetizes.
Young, mobile first, crypto fluent, sports obsessed demographics. Event market demand is real and is met today only through offshore venues. No licensed local operator has entered either market in prediction markets.
Football mad, with fast rising crypto adoption. Polymarket is blocked or absent in key markets. Demand leaks to offshore venues with no local currency support and no regulatory standing.
Licensed brokers already operate here. Event markets are effectively unserved. A localized, regulated operator has a wide open lane, with the regulatory relationships already in place.
The acquisition math is what operators are underestimating
Acquiring a funded FX or CFD account costs $200–800 in most markets. In Tier 1 markets (UK, EU, UAE) that can reach $1,850. Prediction market entry benchmarks at $30–300, skewing to the low end on organic, event driven activity.
The mechanics: under 3 minutes from signup to funded, $10 minimum deposit, $10–50 new user incentive versus $1,000+ sportsbook welcome bonuses.
Robinhood crossed one million prediction market customers by activating its existing base, not new acquisitions. Every major event is a reengagement trigger for lapsed traders in your database at near zero incremental CPA, then a channel back into the higher LTV CFD or crypto book on a single wallet.
What this means if you run a trading platform
$50 billion in a single month answered the demand question. The question now is structural: who builds the operator layer outside the US, and how much does that window cost to reopen once it closes?
The advantage is the infrastructure FX brokers and crypto exchanges have spent years building: local licenses, local payment rails, local currencies, local trust. Kalshi's technology is excellent. What it cannot replicate in your markets is the infrastructure you already have.
Your users are already speculating on macro events, sports outcomes, and price movements. Prediction markets formalize that into a monetizable product without a new acquisition budget. The Kalshi of Africa, Southeast Asia, and MENA does not exist yet. Every quarter of waiting roughly doubles the cost to capture the same position.
Key takeaways
Group stage play drove prediction market spikes that validated the sports thesis. Tournament volume is tracking toward the $2.5 billion projection, confirming that concentrated sporting events move the volume floor in a way no other catalyst has.
Both incumbents pushed prediction market app development into full build mode through Q2. US CAC is now measurably higher across all their acquisition channels as a result. The cost to compete in that market is resetting upward with each quarter.
Kalshi has publicly stated it needs "the Robinhoods of each major country" internationally. No licensing or white label deals were announced outside the US in Q2. The international operator layer remains structurally open.
Institutional margin went live in Q2. Early uptake signals whether traditional finance treats prediction markets as a real hedging instrument and whether institutional flow can lift the volume floor beyond what retail alone drives.
Add prediction markets to your platform.
Shift provides the operator infrastructure. Your brand, your users, your revenue. Live in weeks.
