Crossover Markets Raises $31M in Series B Funding at $200M Valuation to Grow Institutional Crypto ECN

The quiet power move in markets rarely comes with fireworks. It usually shows up as infrastructure. Pipes. Rails. The kind of thing most people never see but every serious player depends on. This week Crossover Markets just reminded everyone that the future of institutional crypto trading will look a lot more like FX than the chaos casino that dominated the early years.

Crossover Markets locked in $31M Series B at a $200M valuation, led by Tradeweb Markets, with participation from DRW Venture Capital, Illuminate Financial, Ripple, Virtu Financial, Wintermute Ventures, and XTX Markets. When firms like that show up with capital, it is not sightseeing. These are the builders of global liquidity, the operators who care about microseconds, execution quality, and market structure that actually scales.

Credit where it is due. Congratulations to Brandon Mulvihill, Co-Founder and CEO, Vladislav Rysin, Co-Founder and CTO, and Anthony Mazzarese, Co-Founder and CCO. This trio did not stumble into digital assets from the hype cycle. Their roots run deep through electronic FX. Brandon Mulvihill ran global FX prime brokerage at Jefferies. Vladislav Rysin engineered some of the fastest matching technology in the FX world at FastMatch and Euronext FX. Anthony Mazzarese spent years building institutional distribution at Jefferies and Citibank. In other words, people who understand how real markets behave when billions move through the pipes.

The product is CROSSx, an execution only institutional ECN for digital assets. No custody games. No broker conflicts. Just pure execution. The engine runs out of Equinix LD4 with sub-20 microsecond latency and the ability to process millions of messages per second. Institutional participants can interact through tailored liquidity pools that account for trade size, spread sensitivity, and toxicity. For the traders reading this, that detail matters more than marketing copy ever could.

Since launch, CROSSx has already matched more than $50B in notional trading volume across roughly 12M trades and brought close to 100 institutional participants onto the venue. That traction tells a bigger story about where the digital asset market is heading. Institutions do not want noise. They want structure, performance, and rulebooks that look familiar to the electronic markets they already trust.

That is exactly why the Tradeweb piece here is so interesting. Tradeweb built one of the most important electronic marketplaces in global finance. Their clients are asset managers, hedge funds, central banks, and dealers that move serious size. Plug that ecosystem into an institutional crypto ECN and suddenly digital assets start speaking the language of traditional markets.

There is a lesson here for founders watching from the sidelines. The companies attracting serious capital right now are not chasing attention. They are solving market structure problems with technology that professionals respect.
