- DRW posted a prediction‑market trader job listing, demanding real‑time monitoring of Polymarket and Kalshi, detection of cross‑platform price gaps, and sub‑second arbitrage execution.
- Wintermute announced hiring algorithmic traders with prediction‑market experience, expanding its market‑making into binary‑event contracts.
- IMC similarly listed openings for quantitative traders to run desks on Polymarket and Kalshi, signaling broader proprietary‑trading interest.
- Polymarket processed $22‑$40 billion in total 2025 volume, with sports markets alone generating >$730 million across the UEFA Champions League, NBA, and NHL events ahead of the 2026 World Cup.
- Betfair priced the “Next UK Prime Minister” market at $0.50 while Polymarket lagged at $0.24, creating a cross‑exchange arbitrage window that a quant could exploit for profit.
- HyperLiquid is being built as an on‑chain exchange to support prediction‑market trading ahead of major events, providing the infrastructure needed for high‑speed arbitrage.
Why it matters: Institutional quant firms gain new profit streams from short‑term arbitrage, while specialized sports‑betting groups continue to drive market accuracy, meaning the influx of capital tightens spreads and boosts liquidity without improving outcome forecasts and the cross‑currency settlement complexity underscores the advantage of large trading firms with sophisticated infrastructure.
