TRM Labs has indicated that prediction markets—platforms allowing traders to buy and sell contracts tied to the outcomes of real-world events like elections, geopolitical conflicts, economic shifts, sports results, and pop culture happenings—have evolved from niche forecasting tools into a major financial phenomenon.
Once limited to early experiments such as Intrade and blockchain pioneers like Augur, these markets now benefit from low fees, seamless composability, global access, and instant liquidity through cryptocurrency infrastructure.
According to an analysis by blockchain analytics firm TRM Labs, the sector has undergone explosive growth, with aggregate monthly trading volume climbing from $1.2 billion in early 2025 to more than $20 billion in January 2026, locking in double-digit billions as a new normal.
The surge reflects more than just bigger bets by existing users.
TRM Labs data shows unique participating wallets nearly tripled, reaching roughly 840,000 per month by February 2026.
On flagship platform Polymarket, a single-day volume record of $425 million was set in February—eclipsing even the frenzy of the 2024 U.S. election—fueled by simultaneous resolutions around Iran-related events.
One contract on whether Iran’s Supreme Leader would exit by late February skyrocketed over 1,200 percent in value within 24 hours, while overlapping markets on regional tensions drew tens of millions in open interest.
Geopolitics now dominates activity, fragmenting across dozens of granular questions on leadership changes, military actions, and diplomatic flashpoints, yet the platform functions like a “super app” by blending politics, macroeconomics, entertainment, and crypto without artificial separations.
Several converging forces powered this scaling.
A pivotal October 2024 court ruling cleared Kalshi to offer election contracts, sparking mainstream media attention just weeks before the presidential vote.
By January 2025, Kalshi expanded sports betting nationwide, and a Robinhood partnership funneled Super Bowl liquidity past $1 billion—introducing the product to millions of new users.
Institutional interest followed: in October 2025, the New York Stock Exchange’s parent company, ICE, disclosed plans for up to a $2 billion investment in Polymarket at an $8 billion valuation.
Regulatory tailwinds continued into 2026 when the CFTC withdrew restrictive proposals and granted Polymarket a no-action letter, lowering legal risks for U.S. participation.
Mainstream integration accelerated the momentum, with Google Finance embedding live odds and high-profile media appearances creating a self-reinforcing “distribution flywheel.”
TRM Labs’ on-chain examination of Polymarket’s smart-contract data reveals a maturing user base.
Mid-frequency traders (11–1,000 fills) and high-frequency market makers together account for roughly 80 percent of volume, while casual and first-time participants remain modest.
Profitability patterns vary: some wallets score big on macro convictions or algorithmic spread capture, while others capitalize on event-driven spikes. Yet the transparency that enables this growth also flags risks.
TRM identified clusters of coordinated wallets that turned modest stakes into outsized gains around sensitive Iran developments, raising questions about potential information advantages or manipulation in thinner markets.
In response, both Polymarket and Kalshi rolled out enhanced integrity measures in March 2026, including stricter rules on non-public information and blockchain-powered surveillance.
Despite regulatory pushback in states like Nevada and Arizona, prediction markets appear poised to mature into essential infrastructure for real-time information discovery and risk pricing.
Their continued expansion will hinge on balancing innovation with proper safeguards against abuse.
As TRM Labs notes, the blend of pseudonymity, composability, and global reach that fueled the boom also demands vigilant oversight to sustain trust in this rapidly evolving asset class. With volumes now measured in tens of billions monthly, these platforms are no longer on the fringe—they are reshaping how the world prices uncertainty.
