Founder Scott Hughes (GitHub @scott-c-hughes) built Onyx to treat prediction markets like traditional financial markets, addressing what he identified as missing primitives in existing Polymarket UIs: lack of basic execution tools, high UI latency, and no support for stop-loss orders. The product was publicly debuted on Hacker News on December 8, 2025 ('Show HN: Onyx – Trading Terminal for Polymarket'). The production interface lives at onyxterminal.xyz with a 'pro' tier surface at pro.onyxterminal.xyz, and the open-source repository is at github.com/scott-c-hughes/polymarket-terminal. On the Polymarket Builder leaderboard Onyx Terminal ranks #336 all-time at $644 cumulative across 4 unique users — early-stage builder volume from a recently launched product.
Onyx Terminal is a Bloomberg-style web trading terminal purpose-built for Polymarket. The product was created by Scott Hughes (GitHub @scott-c-hughes) to address what he publicly described as three missing primitives in existing Polymarket UIs: lack of basic execution tools, UI latency that punished active trading, and absent stop-loss support. The terminal frames prediction markets like traditional financial markets — fast order entry, dense panel layouts, news/OSINT integration, and global event tracking.
The product debuted publicly on Hacker News on December 8, 2025 ('Show HN: Onyx – Trading Terminal for Polymarket', item 46197660). The codebase is open-source at github.com/scott-c-hughes/polymarket-terminal — described as a 'Bloomberg-style terminal for monitoring Polymarket prediction markets with news, OSINT, and global tracking,' written in JavaScript (90.6%), CSS (7.2%) and HTML (2.2%), with a Vercel deployment mirror at polymarket-terminal-lemon.vercel.app. The repository has light star/fork activity (1 star, 13 commits as of recent snapshot), consistent with a recently launched solo-developer project.
The production product runs at onyxterminal.xyz with a 'pro' tier at pro.onyxterminal.xyz. WebFetch of both surfaces returned thin content (just 'Onyx Terminal' title), suggesting an SPA-style architecture where the meaningful product copy is rendered client-side and not visible to text-extraction crawlers — common for trading terminals.
Leaderboard traction is early-stage: rank #336 all-time at $644 cumulative routed across 4 unique users. The post-launch on-chain footprint is small but consistent with a December 2025 launch that has not yet scaled. No funding round, pricing tier, or team beyond Scott Hughes is publicly disclosed; the project is at the Show HN / open-source-solo-dev stage of maturity.
