Brahma, founded in 2021, has processed more than $1B in transactions through its unified on-chain smart account system, which automates complex crypto operations and bridges traditional finance with DeFi payment rails.

As part of the acquisition, Brahma’s products will sunset in 30 days with full fund access retained, and its team and technology will now focus on scaling Polymarket’s stack and ecosystem, according to a Wednesday statement.

The acquisition aims to improve the user experience by simplifying wallet setup, deposits, and token redemptions, and increasing liquidity for small wagers. It follows previous Polymarket expansions through the Dome and Lunch acquisitions.

Polymarket is building a full-stack prediction market platform by uniting crypto rails, liquidity tools, and real-time surveillance systems.

The firm is collaborating with Palantir Technologies and TWG AI to deploy an AI-powered surveillance and compliance system built on Vergence AI. The system will provide real-time trade monitoring, anomaly detection, participant screening, and automated reporting to ensure fairness and transparency.

Polymarket intends to integrate this infrastructure into its US-regulated trading venue under the Commodity Futures Trading Commission, reinforcing its position in the regulated market alongside competitors like Kalshi.

The two prediction market giants are in early-stage fundraising discussions that could value them near $20 billion, doubling prior valuations, though outcomes are still uncertain due to increasing scrutiny.
