Kalshi Partners With Coinbase Custody to Strengthen U.S. Event-Based Trading Infrastructure
Kalshi, the largest regulated prediction market platform in the United States, has announced a major partnership with Coinbase Custody to secure the USDC reserves used across its event-based contracts.
The move, announced on November 13, marks a significant upgrade to the security, compliance, and institutional trust behind Kalshi’s fast-growing trading ecosystem.
USDC Now Secured by Coinbase Custody
Under the new agreement, Coinbase Custody will hold the USDC that backs Kalshi’s markets, offering:
- Cold storage protection
- Segregated accounts
- Institution-grade compliance standards
Kalshi says the partnership will give traders stronger confidence that deposited funds remain safe and stable, even during periods of high trading volume or political volatility.
Prediction markets depend heavily on trust, especially when users are wagering on outcomes such as elections, economic reports, or sports events. Kalshi says combining its CFTC-regulated exchange framework with Coinbase’s custody infrastructure brings event contracts closer to mainstream financial products.
USDC remains the platform’s core settlement asset due to its price stability and fast on-chain settlement, making it ideal for real-time trading. With Coinbase Custody now safeguarding these reserves, Kalshi expects user confidence to continue rising.
Follows October Integration With Base
The custody expansion comes shortly after Kalshi integrated with Coinbase’s Base network in late October—an update that reduced fees and accelerated USDC deposits for new users entering the platform.
A Breakout Year for Kalshi
Kalshi’s 2025 growth has been rapid and widely watched:
Explosive Valuations
- October funding offers valued Kalshi at over $10 billion, doubling a separate $5 billion valuation from another $300M round earlier that same month.
- In June, Kalshi raised $185 million at a $2 billion valuation, bringing total funding to $415 million.
Competitors such as Polymarket have also attracted major investment, reflecting massive momentum across the event-based trading sector.
Mainstream Visibility
- On November 6, Google Finance began displaying real-time odds from Kalshi and Polymarket, a major milestone for prediction markets entering traditional financial tools.
- Kalshi’s political markets drew national attention after the platform forecast Donald Trump’s election victory hours before traditional media projections.
Building for Long-Term Stability
Kalshi says its partnership with Coinbase Custody is a foundational step toward building a more secure, more trusted market structure capable of supporting the platform’s accelerating growth.
With custody upgrades, Base integration, and expanding mainstream visibility, Kalshi is positioning itself as the core infrastructure provider for the future of regulated event-based trading in the United States.
