Crypto markets are serving as the entry point for hundreds of thousands of new users, but sports are where they stay. The latest data shows a sector that has grown approximately 130-fold in two years and is now drawing regulatory fire across multiple US states.

Global prediction market trading volume reached $25.7 billion in the most recent monthly period, according to data reported by The Block on April 29, 2026, cross-verified against a CoinSpectator and Bitget Wallet Q1 2026 analysis. The figure reflects a sector that has expanded rapidly on the back of retail participation, with crypto-native users accounting for a disproportionate share of first-time activity on decentralized platforms like Polymarket.

A Q1 2026 analysis by CoinSpectator, drawing on Bitget Wallet data covering 1.29 million Polymarket wallets, found that 82.3% of accounts traded less than $10,000 during the quarter. Among the least active users, who are typically the newest to the platform, crypto markets represented close to 40% of all trading volume. Median trade sizes for Bitcoin and Ethereum contracts came in at $2 to $3. The pattern points to crypto markets functioning as a familiar, low-barrier starting point rather than a primary destination. As users gain experience, their activity shifts toward sports: sports volume share climbs from 22.7% among newer users to 29.2% among more active ones.

Polymarket, which operates on the Polygon and Ethereum blockchains and requires only a crypto wallet and USDC (a dollar-pegged stablecoin) to use, recorded $10.57 billion in volume in March 2026 alone. That was its first month above $10 billion, a 33% increase from February. Its Q1 2026 total of $26.2 billion represented a 90% jump from the previous quarter. In October 2025, Intercontinental Exchange and the New York Stock Exchange made a $2 billion strategic investment in Polymarket, an institutional milestone that underlines the platform's growth trajectory. The sector also set a single-day volume record of $425 million on February 28, 2026, driven almost entirely by Iran-related markets resolving on the same day. Combined volume across Polymarket and its US-regulated rival Kalshi (Polymarket is a decentralized, blockchain-native platform, while Kalshi holds a federal license from the US Commodity Futures Trading Commission) reached roughly $60 billion through mid-April 2026, according to Bernstein research cited by CoinDesk. The sector's full-year 2025 volume totalled approximately $51 billion. For context, monthly volume was below $100 million as recently as early 2024. Analysts at Bernstein project total prediction market volume will hit $1 trillion by 2030, underpinned by an estimated 80% compound annual growth rate, driven by regulatory clarity and blockchain-based global liquidity.

Kalshi has moved aggressively to capture mainstream users. A distribution partnership with Robinhood, announced in March 2025, gave the platform access to 27 million brokerage account holders. According to TRM Labs, prediction markets have become Robinhood's fastest-growing product line by revenue, with 11 billion contracts traded by over one million customers. Kalshi's market share has risen from 3.3% in 2025, per Business of iGaming, to approximately 52.6% by early 2026. The company is also reportedly planning to offer crypto perpetual futures, a move that analysts describe as part of a broader convergence between the prediction market and crypto sectors. Sports is the largest single category across the broader market, accounting for roughly 64% of overall volume, with Polymarket recording $10.1 billion in sports trading during Q1 2026 alone.

The growth is not without legal complications. Wisconsin filed a lawsuit in late April 2026 against Kalshi, Polymarket, Coinbase, Robinhood, and Crypto.com, arguing that event contracts constitute unlawful gambling under state law. Wisconsin Attorney General Josh Kaul summarized the state's position plainly: "Thinly disguising unlawful conduct doesn't make it lawful." Courts in Nevada and New York have already issued similar rulings. The central dispute is whether CFTC federal authority overrides state-level gambling regulations, a question legal experts say could eventually be decided by the US Supreme Court. Coinbase, Robinhood, and Crypto.com have formed a Coalition for Prediction Markets to coordinate their response.

Outside the United States, the picture varies sharply by region. Kenya and Nigeria are among the more accessible emerging markets. Polymarket's wallet-only model means Kenyan users can participate without a US bank account, and the platform's low minimum entry aligns well with the small-value, high-frequency transaction norms of mobile money ecosystems like M-Pesa. Nigeria, with an estimated 168.7 million registered sports bettors and established mobile payment infrastructure, has a ready-made audience. TechCabal has also highlighted prediction markets as a potential tool for crowd-sourced economic intelligence within Africa's startup ecosystem, a framing that positions the sector well beyond pure speculation. Platforms like Predicta Markets are already building Africa and Asia-specific prediction products, with integrations for M-Pesa, Nigeria's Opay, and India's UPI payment system. India itself, however, is a notable exception. The Promotion and Regulation of Online Gaming Act 2025 has led authorities to block ISP access to Polymarket nationwide, cutting off one of the world's fastest-growing crypto markets (South Asia recorded 80% year-on-year growth in crypto adoption per the TRM Labs Q1 2026 Global Crypto Adoption Index, with India cited specifically) from the sector's primary decentralized platform. Elsewhere in South Asia, countries including Pakistan, Bangladesh, and Sri Lanka show regional crypto adoption trends that suggest latent prediction market interest, but platform-specific data for those markets remains limited and the regulatory picture continues to develop.

Bernstein's 2026 sector revenue forecast stands at roughly $2.5 billion, with Robinhood's prediction market business already running at an annualised revenue rate of approximately $350 million, providing concrete grounding for that sector-wide projection. Whether the broader forecast holds depends partly on how courts in Wisconsin and other states resolve the jurisdiction question, and partly on whether platforms can convert the hundreds of thousands of crypto-native users now making $2 trades on Bitcoin markets into habitual participants across sports, politics, and geopolitical events. One structural risk for that conversion is already visible in the data: according to a Financial Times study cited by TRM Labs, 58% of Polymarket wallets are currently in the red, a figure that underscores both the platform's retail reach and the losses many of those newcomers are absorbing.
