Prediction Markets: Retail’s Newest Asset Class Is Quadrupling
Event contracts — tradable yes/no markets on real-world outcomes — are becoming a mainstream retail asset class, with volume on pace to quadruple in 2026.

What are prediction markets?
Exchanges where you trade contracts on real-world outcomes — elections, Fed decisions, sports results — that pay out if the event happens. In 2025–2026 they jumped from niche to mainstream: total volume is on pace to roughly quadruple to $240 billion in 2026, from $51 billion in 2025, with industry forecasts reaching $1 trillion in annual volume by 2030.
How did event contracts go mainstream?
- 2020–2023 — the regulatory wilderness. Event markets exist at the edge of US legality; volumes are tiny, participants are hobbyists and academics.
- 2024 — the election proof-of-concept. A presidential cycle makes prediction-market odds a nightly media fixture. Regulatory wins establish that US customers can legally trade event contracts. Volume explodes around the election — then, crucially, doesn’t die afterward.
- 2025 — the brokerage integration. Robinhood partners with Kalshi to put event contracts inside a mainstream brokerage app; $51 billion in annual volume; sports and Fed contracts prove the demand is continuous, not election-cyclical.
- 2026 — the asset class phase. Volume pacing toward $240 billion; Robinhood’s prediction revenue grows ~50% quarter over quarter ($104M → $156M); contract counts hit 13 billion in a single quarter. Wall Street starts modeling it as a permanent retail product line.
The adoption curve rhymes with options in the 2010s: a product once considered exotic becomes a standard tab in the retail app, and the platforms that own the flow monetize a structurally higher engagement level.
Which stock is the pure-play?
Robinhood. Its prediction-markets partnership became a primary engagement driver in 2026: contract volume grew from 9 billion contracts in Q1 to 13 billion in Q2, with prediction-market revenue jumping from roughly $104 million to $156 million quarter over quarter — alongside record overall results. After a 280% run across 2024–2025, the stock now trades at a premium (roughly 37x sales) that leaves no room for error.
Coinbase also entered the category, and the largest dedicated venues (Kalshi, Polymarket) remain private — meaning public-market exposure is concentrated in one name.
The metrics that matter
- Quarterly contract volume and prediction revenue at HOOD — the growth curve everyone is underwriting ($104M → $156M QoQ is the pace to beat).
- Volume seasonality — the bear question is how much volume is event-driven (elections, playoffs) vs. continuous. Watch off-cycle quarters for the answer.
- The Kalshi–Robinhood relationship — Robinhood drove over half of Kalshi’s volume, then began routing to an affiliated exchange (Rothera), turning partner into competitor. The economics of who owns the exchange layer are unsettled and material.
- Regulatory jurisdiction fights — event contracts sit between market and gaming regulators; state-level challenges and any adverse federal ruling are the tail risks.
- New contract categories — each added category (economic data, entertainment, weather) expands TAM; blocked categories mark the regulatory ceiling.
- Kalshi/Polymarket IPO signals — an IPO would create the first pure exchange play and re-rate the whole category.
Second-order plays
| Expression | Names | Angle |
|---|---|---|
| Distribution | Robinhood (HOOD) | The only liquid pure-ish play; prediction is its fastest-growing line |
| Crypto-adjacent | Coinbase (COIN) | Entered the category; second-order exposure |
| Private leaders | Kalshi, Polymarket | The exchanges themselves — IPO candidates that would define the category |
| Legacy exchanges | CME Group (CME) | Runs its own event contracts; the institutional incumbent watching the upstarts |
The bear case, steelmanned
First, regulatory fragility: event contracts exist in contested jurisdiction; gaming regulators, state attorneys general, and consumer-protection advocates all have live challenges, and one adverse ruling could shut categories (especially sports) that drive most volume. Second, the volume quality question: quadrupling volume during a period stacked with elections and sports seasons may overstate steady-state demand — engagement products look like secular growth until the novelty cycle turns. Third, HOOD-specific concentration: at ~37x sales, Robinhood prices in flawless execution across prediction markets AND crypto AND equities; its prediction economics also depend on exchange relationships (Kalshi → Rothera) that are being renegotiated in real time. Fourth, the social criticism: a product line this close to gambling invites political attention that pure investing products don’t.
The bull rebuttal: the same criticisms tracked options and sports betting for a decade while both became enormous, permanent markets. Flow products that increase engagement rarely reverse once embedded in the retail app.
The options-boom analogy
The closest rhyme is retail options adoption from 2015–2021: an instrument professionals used, repackaged into a one-tap retail product, dismissed as gambling, then normalized into the largest retail flow business in history. Prediction markets are running the same curve faster. The lesson from options: the durable winners were the platforms that owned the customer, not necessarily the exchanges — and the product survived every "this is gambling" news cycle. The caveat: options had decades of regulatory settlement behind them; event contracts are building that foundation live.
What are the risks?
Three, in order: regulatory reversals (contested jurisdiction), partner economics (routing changes could turn Kalshi from partner into competitor), and valuation — a 37x sales multiple prices in years of flawless execution.

Investability Verdict
Watch closely — this is what an emerging trend looks like before the crowd fully arrives: quadrupling volumes, a single liquid pure-play, and private leaders (Kalshi, Polymarket) whose eventual IPOs would expand the investable set. The trade today is HOOD or nothing, and its valuation makes timing matter enormously.
Frequently Asked Questions
How fast are prediction markets growing?
Total volume is on pace to roughly quadruple to $240 billion in 2026 from $51 billion in 2025, with industry forecasts of $1 trillion in annual volume by 2030.
What is the best prediction market stock?
Robinhood (HOOD) is the only meaningful public pure-play as of August 2026 — its prediction-market revenue grew ~50% quarter over quarter to $156 million. The largest dedicated venues, Kalshi and Polymarket, are still private.
What are the risks of investing in prediction market stocks?
Regulatory uncertainty (contested jurisdiction between market and gaming regulators), concentration (one public pure-play at ~37x sales), and shifting partner economics between platforms and exchanges.
Are prediction markets just gambling?
They occupy the contested space between markets and gaming — economically they aggregate information like futures markets, while sports contracts feel like betting products. The unresolved classification is precisely the regulatory risk, and the historical rhyme is retail options, which survived the same criticism to become a permanent asset class.
What would expand the investable universe?
A Kalshi or Polymarket IPO — either would create the first pure exchange play, likely re-rate the category, and give investors an alternative to concentrated exposure through Robinhood.
Why did Robinhood and Kalshi become competitors?
Robinhood drove over half of Kalshi’s volume, then began routing contracts to its affiliated exchange (Rothera) — converting a distribution partnership into vertical competition for the exchange economics. How that resolves determines who captures the category’s margin.
