Creating liquidity in private markets is not about better tech like blockchain. The core challenge is one of market structure: finding a buyer when everyone wants to sell. Without a mechanism to provide a capital backstop during liquidity shocks, technology alone cannot create a functional secondary market.

Today's market structure, dominated by High-Frequency Trading (HFT) firms, is inherently fragile. HFTs provide liquidity during calm periods but are incentivized to withdraw it during stress, creating "liquidity voids." This amplifies price dislocations and increases systemic risk, making large-cap concentration more dangerous than it appears.

Kalshi architects a healthier marketplace by differentiating its fees. Liquidity providers, who take on risk by posting orders, receive lower fees. In contrast, traders who 'snipe' mispriced odds by taking liquidity pay higher fees. This incentivizes pro-social behaviors like maintaining a stable market.

Over 95% of matched orders on Kalshi come from thousands of individuals and small shops, not large institutional market makers. These 'super forecasters' can price diverse, fast-moving markets (like politics or culture) far more dynamically than traditional firms, forming the true backbone of the exchange's liquidity.

For 99% of ETFs, liquidity and bid-ask spreads are not based on the ETF's own trading activity. Instead, they reflect the cost for a market maker to buy or sell the underlying basket of securities. An ETF holding liquid stocks can trade billions with tight spreads, even if the ETF itself is rarely traded.

Kalshi uses market makers to solve the cold-start problem and bootstrap liquidity for new contracts. However, as a market becomes more successful and organic volume grows, the percentage of market maker participation intentionally decreases. Their role is to ignite the flywheel, not to be the engine itself.

Robinhood observed that over 70% of stock token trading volume occurs outside standard exchange open hours, primarily overnight and on weekends. This volume indicates significant global demand for continuous execution when traditional markets are closed.

The rise of systematic and electronic trading has fundamentally altered credit market structure. Turnover for every dollar of bonds issued has doubled from 3.5x to 7x in a decade, creating a deeper, more resilient pool of liquidity that is less prone to disappearing in a shock.

Much of HFT is a game between market makers and liquidity takers. When a related asset moves, makers race to cancel their now-mispriced ('stale') orders. Simultaneously, takers race to execute against those same orders. This core conflict is what fuels the arms race for speed.
