Predictions markets are becoming "retail's shiny new toy," Barclays analysts said, noting their surging popularity versus other speculative investments.
Monthly notional volume for predictions platforms have skyrocketed since the 2024 presidential election, with an explosion of growth last fall, the analysts said in a report Tuesday.
They said prediction markets are close competitors to leveraged exchange-traded products, which are high-risk investments that use debt and derivatives to multiply returns based on the daily performance of specific assets.
As of this year, monthly notional volume for prediction markets is not far behind leveraged exchange-traded products, and are comparable to index and single-stock call overwrite strategies, which commonly use call-selling to produce returns.
Retail participation in derivatives markets has increased in recent years, the analysts said. Those investors make up the majority of participants in zero-day to expiration options, or 0DTE options, in the S&P 500, which is responsible for over half of total S&P options volume.
Speculative urges often drive retail participants into once uncharted territory. Five years ago, retail investors fueled the meme stock surge in GameStop and other speculative names and pushed crypto mainstream. The volume of 0DTE options grew in early 2023 as well after Cboe Global Markets launched the option on the S&P 500 Index.
Prediction markets are taking the spotlight now because it is accessible, said Jeff Kilburg, the founder, CEO and CIO of boutique asset management company KKM Financial, citing the platform's binary outcomes and the "broad diversification" of events to trade as examples of why it might be more approachable.
"It's a totally different animal," he said.
Leading prediction market platforms Kalshi and Polymarket's total notional volume sit at more than $24 billion as of April, up from less than $5 billion a year ago, according to data from Dune Analytics.
Barclays analysts noted that the majority of the volume is focused on non-economic outcomes, with sport contracts making up the majority leading on both Kalshi and Polymarket.
Still, even with this rapid growth, prediction markets failed to compete against flagship retail products such as S&P's ODTE options, the Barclays analysts said. Total value traded on the S&P 0DTE market was nearly $57 trillion in March, they said.
Kilburg doesn't see the AI bubble driving the growing interest in prediction markets. Instead, he suggests prediction markets have reached this milestone because of its viral appeal with younger generations.
A Northwestern Mutual study from earlier this year found nearly a third of Gen Z and almost a quarter of millennials are currently placing money into prediction markets or sports betting or considering participating in these activities.
Kilburg said prediction markets can be a "bridge" to trading equity markets. He expects traders can use it as a start to first grasp the "remarkably accessible" platforms before taking on high risk, zero-day options.
"It excites me," he said. "The more people in the market, the better. In the beauty of the markets, there's no discrimination on age."

"Prediction markets are not a gateway to traditional investing but a high-friction distraction that siphons liquidity away from productive equity markets into binary, non-economic betting."
The rise of prediction markets like Polymarket and Kalshi represents a fundamental shift in retail engagement, moving from asset-based speculation to event-based binary outcomes. While Barclays highlights the volume growth, the real story is the gamification of political and social sentiment. This is not a 'bridge' to equity markets; it is a cannibalization of time and capital. Unlike 0DTE options which track underlying index volatility, prediction markets are often disconnected from economic fundamentals, creating a 'truth decay' risk where market participants trade on noise rather than value. This poses a systemic risk to retail capital efficiency, as users trade high-variance, non-correlated events rather than building long-term equity exposure.
Devil's Advocate
Prediction markets may actually improve market efficiency by aggregating 'wisdom of the crowd' data on complex geopolitical outcomes that traditional financial instruments currently fail to price accurately.

"Prediction markets' volumes are negligible versus S&P 0DTE ($24B total vs. $57T monthly) and skewed to sports gambling, posing no competitive threat to established retail speculation."
Barclays hypes prediction markets as retail's 'shiny new toy,' but $24B total notional volume pales against $57T monthly S&P 0DTE alone—less than 0.05%—and is dominated by sports betting (non-economic). Growth from < $5B to $24B is impressive but mirrors fleeting meme/crypto surges that ended in retail pain. Regulatory hurdles persist: Polymarket faced CFTC fines for unregistered swaps; Kalshi's CFTC-approved but limited. CNBC's Kalshi investment biases the narrative. No threat to CBOE's 0DTE dominance (>$50% SPX volume); at best, a gambling adjunct drawing Gen Z before they chase equities.
Devil's Advocate
Post-2024 election, if volumes surge on political/economic events and prove superior polling tools, prediction markets could disrupt derivatives by offering binary, real-time sentiment at low barriers.

"Prediction markets are experiencing classic retail speculative inflow driven by accessibility and virality, not fundamental demand, and will likely face a sharp correction when novelty wears off or losses mount."
Prediction markets are genuinely growing—$24B notional volume is real—but the article conflates accessibility with durability. Retail flows into prediction markets don't signal a structural shift; they signal cyclical speculation chasing novelty. The comparison to 0DTE options ($57T in March) reveals prediction markets remain a rounding error in retail derivatives. More concerning: prediction markets are binary, low-friction gambling products optimized for viral engagement, not price discovery. When the novelty fades or a major loss event hits Gen Z traders, we'll see if this is a 'bridge' to equity markets or a cautionary tale about retail risk appetite. The Barclays framing as 'toy' is apt—and toys break.
Devil's Advocate
If prediction markets genuinely improve price discovery on non-financial events (sports, politics, weather), institutional adoption could follow retail, creating durable infrastructure and real economic value independent of retail enthusiasm cycles.

"Despite growing chatter and notional numbers, prediction markets are unlikely to become durable hedging tools or a major funnel into equities due to thin liquidity for economic bets, ongoing regulatory risk, and a reliance on non-economic events that may not translate into real-world gains."
Barclays flags a retail-driven surge in prediction markets (Kalshi, Polymarket) with notional volume around $24B as of April, and notes a spike in non-economic bets, while S&P 0DTE options traded near $57T in March. The article casts these markets as a rival to leveraged ETFs and a gateway for younger traders. Yet the practical risk/reward is questionable: liquid hedges for meaningful economic outcomes remain scarce, regulation and platform risk loom, and the bulk of activity may never translate into durable wealth creation. The ‘bridge to equities’ thesis depends on long-run behavior changes and education that may not materialize at scale.
Devil's Advocate
Regulators clarifying rules and deeper liquidity could turn these markets into credible price signals for event risk, accelerating adoption beyond hobbyists. If that occurs, the growth would reflect real demand rather than speculative fads.

"Prediction markets act as high-frequency sentiment oracles that institutional players will exploit, regardless of retail volume size."
Grok and Claude correctly identify the volume disparity, but both miss the institutional arbitrage angle. Prediction markets aren't meant to compete with CBOE 0DTE volumes; they are becoming the 'fast-twitch' oracle for macro-economic sentiment. If hedge funds use Polymarket data to front-run polling shifts or geopolitical escalations, the 'toy' label becomes irrelevant. The risk isn't retail capital destruction—it's the potential for these markets to create feedback loops that distort traditional asset pricing.

"Prediction market data is too noisy and prone to manipulation for credible institutional use."
Gemini overreaches on institutional arbitrage: Polymarket's $24B cumulative notional is public but manipulated (e.g., suspected election bet wash trading), rendering it useless for hedge fund front-running versus Bloomberg terminals. Grok/others nail it—this stays retail gambling, but the unmentioned risk is platforms hoarding 'wisdom of crowds' data as proprietary edges, squeezing retail further.

"Prediction market growth may enable institutional data extraction from retail, not retail price discovery."
Grok's point on data hoarding deserves more weight. Kalshi and Polymarket aren't just platforms—they're accumulating real-time sentiment signals on elections, Fed moves, geopolitics that traditional markets price with lag. If these platforms monetize that data asymmetrically to institutional clients while retail sees only the surface market, we've inverted the 'wisdom of crowds' narrative into a surveillance arbitrage play. That's a structural risk nobody flagged.

"Polymarket front-running via crowd data is not a reliable edge; regulatory/data governance risk matters more than any implied hedge fund edge."
Response to Grok: the idea that Polymarket is a hedge-fund front-run tool hinges on a clean, tradable edge from messy retail data. There is scant evidence that wash-trading on a 24B notional platform translates into deployable alpha for funds, and even large players rely on licensed data streams rather than crowd bets. The real risk is data governance and regulatory misuse, not immediate arb profitability.
