U.S. proprietary trading firm Tradeify has launched Slay Markets, a new retail futures brokerage operating under its recently formed introducing broker entity Tradeify Brokerage LLC, and signed a clearing and technology agreement with NinjaTrader Clearing LLC and NinjaTrader Connect.
The retail waitlist opened today at slaymarkets.com. Early access will go to Tradeify’s existing funded traders, with broader retail availability following in the coming weeks. The move marks Tradeify’s first expansion beyond its evaluation and funded trading programs.
Tradeify Brokerage LLC is the customer-facing introducing broker, registered with the CFTC and a member of the National Futures Association. NinjaTrader Clearing LLC sits behind it as the sole CFTC-registered futures commission merchant, holding client funds, clearing and executing all trades. Customers contract with Tradeify Brokerage LLC but their money is held at NinjaTrader.
This IB/FCM separation is the standard model across most of the U.S. retail futures market. As of April 30, 2026, the NFA counted 69 futures commission merchants and 885 introducing brokers among its membership, according to NFA directory data.
The NinjaTrader arrangement
The exclusivity means NinjaTrader is the only clearing and technology partner behind Slay Markets. The agreement covers both the regulated clearing side and NinjaTrader Connect, which the company describes as an end-to-end infrastructure platform providing onboarding, funding, risk controls, and market access through a single API.
That lets Tradeify offer CME Group futures access to its trader community without building its own FCM stack or core brokerage technology.
“Tradeify was built to help retail traders develop their skills and scale their trading. Creating an easy path to take their capital to a live brokerage account when they felt they were ready was a necessary chapter in that journey,” said Brett Simberkoff, CEO of Tradeify. “With NinjaTrader handling the infrastructure, Tradeify aims to focus on creating the best possible user experience.”
Martin Franchi, CEO of NinjaTrader Group, said the move from prop firm to introducing broker “represents a natural extension for firms exploring new ways to serve traders.”
“NinjaTrader’s battle-tested infrastructure is built to support that evolution, giving firms the technology and framework to launch, differentiate, and scale a complete trading experience,” Franchi said.
