Problem

Prediction markets are becoming increasingly fragmented across exchanges such as Kalshi, Polymarket, and other venues. Liquidity is scattered, identical contracts are difficult to match, and traders must navigate different interfaces, fee structures, rules, and settlement risks. The result is market inefficiency, slower time-to-trade, and operational overhead that is especially painful for serious traders and teams.

The killer use case is for systematic traders, market makers, and high-volume individuals who need to identify cross-venue pricing discrepancies and execute quickly at scale. Without shared infrastructure, these users must build and maintain separate exchange connectors, data pipelines, risk systems, and trading interfaces, creating a substantial barrier to entering or scaling in prediction markets.

Product / Service

Valence is a unified prediction-market trading terminal and API layer. Its web-based terminal consolidates order books, positions, balances, P&L, charts, blotters, and risk information, while its execution system routes and shards orders across venues to seek the best available price. It supports both manual and systematic trading, allowing users to trade across multiple exchanges from one workspace rather than juggling separate accounts and interfaces.

For more advanced users, Valence provides standardized APIs, cross-platform ticker matching, historical and proprietary data for backtesting, and tools for deploying automated strategies. The product is delivered as a volume-priced software service with Pro, Premiere, and Automated tiers, including increasingly advanced execution, risk controls, integrations, API access, and support; the company advertises no monthly minimums and custom pricing for larger traders.

Market

Valence competes in the emerging prediction-market trading infrastructure and aggregation category. Its venue-level substitutes include trading directly on Kalshi, Polymarket, or Crypto.com, while other emerging tools include multi-venue terminals such as Stand and Polymtrade. Valence differentiates itself by combining cross-venue execution, unified data, low-latency infrastructure, portfolio monitoring, and systematic-trading capabilities in one product. Trading firms can also choose to build comparable connectors and infrastructure internally.

The company appears commercially live rather than pre-revenue: its site advertises volume-based fees, reports more than 1 billion contracts traded, and cites $200 million-plus in monthly volume, 99.9% uptime, and live trader testimonials. YC materials report growth from 7 million contracts in September to 250 million in December 2025, a top Kalshi trader executing more than 100 million contracts per month through Valence, and one team scaling P&L fivefold after adopting the platform. These are company-reported traction figures, and no revenue total was disclosed in the reviewed materials.
