"The World Cup was really a proof-of-concept there." — Vlad Tenev, CEO, Robinhood Markets
Prediction markets posted $50.59 billion in combined trading volume in July 2026, an all-time monthly record, according to data aggregated by DeFi Rate from Kalshi, Polymarket, and Polymarket US. The figure represents a tenfold increase from September 2025, when combined monthly volume sat below $5 billion. Bernstein estimates total 2026 volume will reach $240 billion, a 370% increase year-over-year, and projects the sector will scale to $1 trillion in annual volume by 2030.
The structural consequence is already visible in public company earnings. Robinhood Markets (NASDAQ: HOOD) reported Q2 2026 prediction market revenue of $156 million, surpassing crypto trading revenue of $100 million for the first time in the company's history. This marks a reversal in the composition of speculative retail finance: event contracts — binary wagers on real-world outcomes — are absorbing transaction share from spot crypto trading, which has declined at Robinhood for three consecutive quarters.
The shift carries implications for the broader digital asset industry. As CFTC-regulated prediction markets formalize into a mainstream asset class, they introduce a competing demand sink for the same retail capital that has historically flowed into crypto speculation. The economic question is no longer whether prediction markets will reach scale, but whether their growth comes at the direct expense of crypto trading volumes.
Combined monthly volume across Kalshi, Polymarket, and Polymarket US reached $50.59 billion in July 2026, a 7.8% increase over June's revised $46.95 billion, per DeFi Rate. Kalshi alone recorded $37.7 billion — roughly 74.5% of the combined total — its highest monthly figure on record and a 14% month-on-month gain. Polymarket US posted $5 billion, up 54% month-on-month, its strongest month since the iOS waitlist was removed in May.
The 2026 FIFA World Cup, which concluded with its final on July 19, drove the majority of the increase. Kalshi's market on the Spain-Argentina final drew approximately $1.9 billion on a single match. Polymarket's World Cup winner contract attracted around $4 billion. Chainalysis recorded $20 billion in on-chain prediction market volume tied to the tournament since January, with close to 400,000 wallets participating.
Sports contracts accounted for 80% of volume on Kalshi and 39% on Polymarket, while crypto and politics combined for 52% of Polymarket's turnover. During the tournament, prediction markets accounted for 27% of all U.S. legal sports betting volume, up from 9% in January 2026.
For context: the total amount wagered through legal U.S. sportsbooks in 2025 averaged approximately $14 billion per month, according to Pew Research Center analysis of data from The Block. Prediction markets are now operating at multiples of traditional sportsbook volume.
Post-tournament open interest across the three venues fell approximately 40%, from around $2 billion at the start of July to $1.2 billion by month-end. Whether the World Cup-fueled surge persists without a comparable event catalyst remains the central question for the sector's second-half trajectory.
Robinhood reported Q2 2026 total net revenue of $1.31 billion, a 32% year-over-year increase, with diluted EPS of $0.62 against consensus estimates of $0.39-$0.41.
The transaction revenue breakdown tells the structural story:
| Category | Q2 2026 Revenue | Year-over-Year Change | |---|---|---| | Options | $342M | +29% | | Event Contracts | $156M | ~+1,460% | | Equities | $129M | +95% | | Crypto | $100M | -38% |
Event contract revenue grew from $10 million in Q2 2025 to $156 million in Q2 2026 — a roughly tenfold increase. By contrast, crypto revenue fell from $160 million to $100 million over the same period, declining for a third consecutive quarter. Q2 2026 crypto revenue represents less than 30% of the peak figure generated in Q4 2024. Trading volume on Robinhood's own app fell 35% year-over-year to $18 billion; combined with Bitstamp (acquired in 2025), total crypto volume was $40 billion.
Users who previously traded crypto have migrated to event contracts. Robinhood now operates 13 separate business lines each generating annualized revenue exceeding $100 million. Crypto now supplies under 8% of total net revenues.
Bernstein projects Robinhood's prediction market revenue will reach $586 million for full-year 2026, up from $150 million in 2025, representing approximately 17% of transaction-based revenues.
In January 2026, Robinhood and Susquehanna International Group acquired and rebranded MIAXdx, a Miami-based derivatives exchange, into Rothera — a CFTC-regulated Designated Contract Market (DCM) and Designated Clearing Organization (DCO). Most prediction market venues either execute trades or clear them. Rothera does both.
Live trading commenced in late May, starting with contracts tied to the FIFA World Cup and baseball. In Q2 2026, Rothera processed over 3.5 billion contracts and generated $17 million in revenue. The platform pulled in approximately $2 billion in notional trading volume during June alone, capturing roughly 7% of the U.S. prediction market share in its first full month of operation.
The strategic logic is straightforward. Previously, Robinhood functioned as a Futures Commission Merchant (FCM), routing orders to third-party exchanges including KalshiEX and ForecastEX. With Rothera, Robinhood controls execution, clearing, and fee economics on a single vertically integrated stack. CFO Jason Warnick stated during the Q2 earnings call that the company expects "most" prediction market flow to eventually migrate to Rothera.
This creates a competitive tension with Kalshi. If Robinhood's 28.4 million funded accounts increasingly route through Rothera rather than Kalshi, the latter loses a material retail distribution channel. Kalshi, which raised $1 billion at a $22 billion valuation, derives approximately 74.5% of industry volume but remains dependent on aggregator and partner distribution.
The prediction market sector is consolidating around three tiers of participants.
Kalshi commands roughly 74.5% market share by volume as of July 2026, driven by sports contracts (87% of its March 2026 volume). The platform's $22 billion valuation, following a $1 billion raise, exceeds Flutter Entertainment and DraftKings. Its single-charter federal model under CFTC regulation gives it nationwide reach without state-by-state licensing — provided courts and regulators continue to classify event contracts as financial instruments rather than gaming.
Polymarket operates as the primary on-chain venue, posting $7.08 billion in May volume (down 21% from its March peak). ICE/NYSE invested up to $2 billion in October 2025 at an $8 billion valuation. Polymarket's category mix skews toward crypto and politics (52% of turnover), differentiating it from Kalshi's sports-heavy book. Polymarket US, the regulated domestic arm, posted $5 billion in July.
Coinbase crossed $100 million in annualized prediction market revenue within two months of its January 2026 launch. Prediction market contracts and revenue more than doubled quarter-over-quarter in Q2 2026, crossing $100 million in annualized revenue. This diversification is material for a company that posted a $359 million net loss in Q2 on $1.2 billion in total revenue, with trading fee compression continuing.
Cantor Fitzgerald launched prediction market trading for institutional investors in August 2026. The institutional entry signal underscores the sector's maturation beyond retail speculation.
The CFTC's approach to prediction markets underwent a significant shift in early 2026. In February, the Commission formally withdrew a prior proposed rulemaking from the previous administration that would have broadly classified political and sports-related event contracts as "contrary to the public interest."
On March 12, 2026, the CFTC issued an Advanced Notice of Proposed Rulemaking (ANPRM) seeking comment on event contract derivatives. On June 10, the Commission published a full proposed rulemaking suggesting comprehensive amendments to Regulation 40.11, establishing a three-step analytical framework for evaluating whether event contracts warrant heightened scrutiny.
The proposed rule defines factors for assessing public interest, including manipulation risk, settlement integrity, and information leakage by insiders. It articulates distinct treatment for sports contracts and considers whether prohibiting specific contracts would push trading to less-regulated offshore markets. The public comment period closed July 27, 2026.
Enforcement actions have established precedent. In April 2026, the CFTC brought an action against a U.S. Army service member who traded on classified intelligence via a Polymarket contract — establishing that informed trading on prediction markets triggers regulatory liability regardless of whether the venue is domestic or offshore.
The critical unresolved question: are prediction markets financial instruments or gambling? The answer determines whether platforms operate on a single federal charter or require 50 state licenses. Legal challenges are pending in 14 states, and four congressional bills remain in play.
The prediction market migration coincides with structural fee compression in crypto trading. Coinbase's consumer take rate fell from approximately 1.4% in 2021 to below 0.5% by late 2025. The entry of traditional brokerages accelerates this trend.
Charles Schwab launched Schwab Crypto in May 2026, offering BTC and ETH trading at 75 basis points across its 39.9 million accounts and $13.04 trillion in client assets. On August 27, Schwab announced plans to add SOL, AVAX, and LINK. Morgan Stanley's E*Trade platform charges 50 basis points. Fidelity sits at 100 basis points.
The fee stack for spot crypto trading is converging toward traditional equity brokerage margins. For platforms like Coinbase, whose Q2 2026 trading revenue declined 19% year-over-year, prediction markets represent both a diversification opportunity and a competitive threat — the same retail capital that might have traded meme coins is now wagering on World Cup matches at higher velocity.
Robinhood's Q2 data makes the substitution effect explicit: event contract revenue rose $146 million year-over-year while crypto revenue fell $60 million. The net gain to Robinhood's transaction business from this rotation was $86 million.
The prediction market sector's trajectory from a $5 billion monthly niche in September 2025 to a $50 billion monthly category in July 2026 represents one of the fastest scaling curves in financial product history. The structural driver is not speculative exuberance — it is regulatory formalization, institutional infrastructure buildout, and the integration of event contracts into existing brokerage distribution channels.
For the Web3 ecosystem, the implications are direct. Every dollar of retail capital wagered on a World Cup match or an election contract is a dollar not traded on a crypto exchange. The substitution is not theoretical — Robinhood's Q2 2026 earnings quantify it precisely. Whether this competition ultimately reduces crypto trading volumes or whether both markets expand in parallel will depend on whether the aggregate pool of retail speculative capital grows or merely reallocates.
The regulatory outcome will determine scale. If the CFTC's proposed framework holds and courts affirm federal jurisdiction, prediction markets operate as a single-charter national product. If state gaming commissions prevail, the sector fragments. Kalshi's $22 billion valuation and Bernstein's $1 trillion projection both assume the former.
