New York Stock Exchange
The scoreboard, not the game: dark pools execute 51%+ of trades, but NYSE sets reference prices. Value shifted from execution to data ($9.3B ICE revenue) and legitimacy signaling.
Dark pools now execute more trades than the NYSE. In the last quarter of 2024, public exchanges handled less than half of all US stock trades for the first time in history—dark pools captured 51.8% of volume by January 2025. The iconic trading floor—where traders in blue jackets wave paper slips—is now heritage theater. Real price discovery happens in server farms in Mahwah, New Jersey, where microseconds determine billions. ICE acquired NYSE in 2013, recognizing that the exchange's value isn't in executing trades (commoditized, margin-compressed) but in data, listings, and brand. ICE generated $9.3 billion in revenue in 2024, mostly from data subscriptions and connectivity services rather than trading fees. NYSE still commands premium IPOs because going public on the Big Board signals legitimacy—costly signaling that companies pay for in higher listing fees, though NASDAQ now wins more IPOs by count (79 vs 15 in the first half of 2025). The existential question remains: if more than half of trading occurs off-exchange, what exactly is a stock exchange? NYSE's answer: we're the scoreboard, not the game. Prices set here become the reference point even when trades execute elsewhere. That's keystone species logic—remove the reef and the fish still swim, but they lose their orientation.
NYSE's trading floor is mostly theatrical—real trading happens in data centers in Mahwah, NJ. But the floor generates media coverage and brand value worth more than the trades it actually executes.

Biological Parallel
NYSE functions like a coral reef—it doesn't catch the most fish (dark pools do), but it provides the structure around which the entire ecosystem orients. Fish may hunt elsewhere, but they navigate by the reef. If the reef degrades, the whole ecosystem destabilizes even though individual hunting happens independently. NYSE's price discovery anchors the system even when trades execute in dark pools. That's keystone species logic: remove it, and the system loses coherence.
