About Onyx.

Onyx is building the market for people who enjoy being right. Our consumer platform lets people take positions on what happens next across sports, prediction markets, crypto, financial markets, politics, culture, and real-world events.

More than one million users have already found Onyx. Now, we’re bringing that same energy into regulated financial markets through Onyx Predictions, a CFTC-registered introducing broker and NFA member.

In June 2026, we raised a $20 million Series A led by Payward, the parent company of Kraken, valuing Onyx at $220 million less than one year after emerging from beta. Our team comes from Jane Street, DraftKings, Robinhood, xAI, SIG, HRT, and Harvard.

We’re building Onyx in New York with a small team, serious momentum, and no interest in moving slowly. The product is live. The market is growing. The category is still ours to define.

Why Onyx?

Onyx is for people with conviction.

We hire talented people, give them meaningful ownership, and expect them to use it. Our teams stay small, the work stays visible, and the distance between an idea and production stays short.

Onyx moves quickly because our markets move quickly. Titles matter less than judgment, initiative, and the quality of what you ship. Good ideas can come from anywhere, but the person willing to make the call is expected to follow it through.

We value people who are ambitious without ego, intellectually honest, comfortable with uncertainty, and energized by hard problems. We debate openly, decide quickly, and take responsibility for the result.

Come build what’s next with us.
