Lit Market
A trading venue where orders are publicly displayed in a visible order book before execution.
What is Lit Market?
A lit market (or lit venue) is a trading venue where orders are pre-trade transparent — meaning bids and offers are publicly visible in the order book before they are executed. This transparency allows all market participants to see available prices and quantities, contributing to accurate price discovery. The major national stock exchanges — NYSE, Nasdaq, and Cboe — operate as lit markets. Lit markets contrast with dark pools and over-the-counter venues where orders are not publicly displayed before execution. While lit markets provide transparency, large institutional orders displayed on lit venues can signal trading intentions and move prices against the order, which is why institutions often prefer dark pools for block trading.
Example
A limit order to buy 1,000 shares of Microsoft at $415 placed on Nasdaq is immediately visible to all market participants through the consolidated order book. Any trader can see this bid, assess its impact on the market, and decide whether to sell. This pre-trade transparency is the defining feature of lit markets — as opposed to a dark pool where the same order would be invisible until execution.
