The meta · researched Oct 13, 2026
Prediction markets became retail trading’s fastest-growing category in 2026. The money moved to short, repeatable price markets, while stocks stayed nearly untouched. Here’s what the numbers say, and what Tessera built from them.
Thirteen signals
Prediction markets went from $2.0B to $53.0B a month in a year
Combined Kalshi and Polymarket volume, July 2025 to July 2026, and it doubled from May alone. It is the fastest-growing corner of retail trading.
Tessera sits in the fastest-growing category, not a crowded one.
At Robinhood, prediction markets out-earn crypto and stocks
Q2 2026: a record 13.6B event contracts, more than 10× a year earlier, and $156M of revenue, ahead of equities ($129M) and crypto ($100M).
Robinhood users already trade event contracts. Tessera brings the format on-chain, on Robinhood's own chain.
Robinhood now runs its own event-contract exchange
Rothera, a CFTC-licensed exchange and clearinghouse built with Susquehanna, went live in June 2026 and has passed 3.5B contracts.
The parent company treats prediction markets as a core business, not a side feature.
Finance is empty space; combos took over sports
One Kalshi week (Sep 28 to Oct 4): $18.37B traded, $11.82B of it in combos, only $83M in financial markets.
Stock-vs-stock duels and price targets aim at the least-served category.
15-minute markets turned crypto into a growth engine
After Kalshi launched 15-minute markets, crypto went from about 2.6% to 14.5% of its volume. About $7B of $8.17B in September came from 15-minute contracts.
Rolling rounds are how the leaders bring in new players, so the house keeps them open around the clock.
Shorter wins: 5-minute markets out-traded 15-minute
On Polymarket, 5-minute markets did $2.3B against $795M for 15-minute between Feb 15 and Mar 30, 2026. Bitcoin carried 77% of fast-market volume.
Crypto rounds default to 5 minutes, and liquidity is concentrated on the flagship tickers.
Bots trade most of the fast order books
In one week of 15-minute markets, only 36.8% of wallets made a profit. Market makers took the difference from takers.
Pari-mutuel pools that close before the price is locked remove the speed edge bots have on order books.
Volume is not retention
About half of Polymarket's monthly wallets come back the next month; wallets that start in crypto markets return at only about 37%.
Short rounds pull people in. Duels, targets, streaks and profiles are what keep them.

PancakeSwap proved the mechanic, then stalled
Back-to-back 5-minute Up/Down rounds with Chainlink prices and pari-mutuel payouts: $393M lifetime, but only about $7.8M in the last 30 days.
Same proven mechanic, plus stocks, head-to-head duels, player-made markets and a social layer.
Limitless shows price markets work on an L2
Base-native, nonstop hourly and daily markets on crypto and stocks, with points seasons and full revenue rebates to market makers.
Seasons with XP and levels are the standard on-chain growth playbook; Season 0 runs on testnet first.
Showing your trades is now expected
Robinhood Social (beta, March 2026) shows verified trades and P&L, including prediction markets. Kalshi Social has feeds, following and leaderboards.
Public handles, profiles with P&L curves, badges, a live feed and share links for every duel.
Robinhood Chain prices stocks through Chainlink
Mainnet since July 1, 2026. Every Stock Token is an ERC-20 with its own Chainlink feed covering regular, pre, post and overnight sessions; feeds hold their last price when markets close.
Contracts read the same AggregatorV3 interface, and every lock and settle proves the first round after the deadline.
The chain is busy and funding builders
More than $12B of DEX volume and 150M transactions in the first month, mostly memecoins. Robinhood committed $1M to Arbitrum's 2026 Open House program for builders.
A consumer app native to a chain that needs uses beyond memecoins.
- ✓Rolling Up/Down rounds: 5 minutes on crypto, 15 minutes and 1 hour on stocks, back to back, opened on-chain by the first bettor (who earns 1%).

- ✓Bets close before the opening price is read, and settlement proves the first oracle round after each deadline.
- ✓Keeper-optional design: scheduled markets cost nothing until someone bets, and players settle and claim in one transaction.

- ✓Season 0 XP, levels, streaks, badges, public handles, profiles with P&L curves, and referrals.

Risks, stated plainly
Figures are as reported by the linked sources; Kalshi and Polymarket count contracts at $1 face value, which overstates cash at risk. “Reported” marks figures from a single secondary source.
