The stock market has repeatedly reinvented itself — from the Amsterdam Beurs to electronic ECNs. The next transformation is already underway. See History of Stock Markets for the full arc.
70%+ of US public equity volume is executed by algorithmic or high-frequency trading (HFT) systems. HFT firms co-locate servers at exchange data centers to achieve microsecond (and nanosecond) execution advantages. Strategies: market making, statistical arbitrage, latency arbitrage.
Key risk: Flash crashes. The May 6, 2010 Flash Crash saw DJIA plunge ~1,000 points in minutes before recovering. SEC implemented circuit breakers and 'limit up/limit down' rules in response.
Robinhood's 2013 zero-commission model forced the entire industry to eliminate trading fees by 2019. Revenue shifted to payment for order flow (PFOF). GameStop (January 2021): retail investors via Reddit's WallStreetBets drove a 1,700% short squeeze, exposing structural tensions between retail and institutional markets.
Blockchain enables tokenized securities: fractional ownership of stocks, bonds, real estate, and private equity on-chain. Benefits: 24/7 settlement, instant global transfer, fractional access. BlackRock's BUIDL fund tokenized $500M+ of US Treasuries on Ethereum (2024). JPMorgan's Onyx network processes $1B+ in daily repo via blockchain.
US exchanges currently operate 9:30am-4:00pm ET. Extended-hours trading exists but has low liquidity. NYSE and Nasdaq are actively building 24/7 trading infrastructure — driven by global retail demand and crypto market norms.
Projected trajectory: AI-driven market making replaces human specialists entirely. Tokenized securities settle instantly on public blockchain rails. Global retail investors access any market, 24/7, from any device. Traditional exchange monopolies erode as decentralized exchanges (DEXs) capture private market share. Regulatory frameworks will be the key battleground. See Black Monday for context on how past technology-driven disruptions reshaped markets.
