Polymarket Acquires DeFi Startup Brahma to Expand Its Onchain Stack

Polymarket has acquired DeFi infrastructure startup Brahma, marking the prediction market platform’s third acquisition in roughly six weeks as it moves to build out its onchain capabilities in-house. Financial terms of the deal were not disclosed.

The acquisition, announced on March 18, 2026, brings Brahma’s smart account infrastructure under Polymarket’s roof. Brahma, founded in 2021 by Alessandro Tenconi, Akanshu Jain, and Bapi Reddy Karri, has processed over $1 billion in cumulative transaction volume across its DeFi products, according to a Fortune exclusive that first reported the deal.

Brahma will wind down all existing projects with other companies following the acquisition, signaling a full integration into Polymarket’s stack rather than a partial talent hire.

What Brahma’s Infrastructure Solves for Polymarket

Brahma’s core technology targets friction points that prediction market users encounter regularly: wallet creation, deposit conversion, token redemption, and cross-chain operations. These are the exact pain points that slow onboarding and limit liquidity on platforms like Polymarket.

Polymarket CEO Shayne Coplan framed the deal in infrastructure terms.

The $1 billion-plus in transaction volume Brahma has processed serves as proof that the team can operate DeFi infrastructure at scale, not just in test environments. For Polymarket, which is valued at approximately $20 billion, that operational track record matters more than Brahma’s specific product lineup.

One concrete use case: Brahma’s technology could help bring liquidity to smaller, niche prediction contracts on Polymarket. Thinner markets have long been a weak point for the platform, and streamlined onchain execution could lower the barrier for market makers to participate across a broader set of contracts.

Three Acquisitions in Six Weeks Signal a Strategy Shift

Brahma is not a one-off deal. Polymarket acquired two other companies in February 2026: Dome, a Y Combinator-backed startup, and Lunch, a boutique executive search firm. Three acquisitions in approximately six weeks points to a deliberate M&A-driven consolidation strategy.

The pattern reveals what Polymarket is building toward. Dome likely addresses product infrastructure, Lunch solves executive recruiting at scale, and Brahma fills the DeFi plumbing layer. Together, they suggest Polymarket is preparing for a phase of rapid expansion that requires owning, not renting, its core infrastructure.

This comes at a time when macroeconomic uncertainty and a crypto market sitting at a Fear & Greed Index score of 26 have not slowed Polymarket’s appetite for deals. The prediction market giant appears to be building aggressively while others pull back.

The Race to Own the Onchain Stack

Polymarket’s move fits a broader trend in crypto: major platforms are vertically integrating their infrastructure rather than relying on third-party providers. The logic is straightforward. Platforms that control their own onchain execution, wallet abstraction, and cross-chain operations can iterate faster and reduce dependency risk.

For prediction markets specifically, the stakes are high. User experience during high-volume events, such as elections or major policy decisions, depends on infrastructure that can handle surges without degradation. Polymarket’s 2024 U.S. election cycle demonstrated both the platform’s potential and its growing pains.

Brahma co-founder Alessandro Tenconi described the initial contact from Coplan as a late-night Telegram message in September, characterizing it as “builders talking to builders.” That timeline suggests Polymarket had been planning its infrastructure buildout months before the current market volatility set in.

With Brahma’s team now fully dedicated to Polymarket and its third-party commitments winding down, the integration represents a meaningful bet that prediction markets will compete on infrastructure depth, not just market breadth. Whether Polymarket can execute on that thesis will likely become visible in the platform’s product updates over the coming months.
