**Market making** = providing liquidity by simultaneously placing buy and sell orders, profiting from the bid-ask spread. Market makers are the **wholesalers of financial markets** — always ready to buy or sell at quoted prices. **Why market makers exist 2026**: 1) **Provide liquidity**: instant execution for traders. 2) **Tight spreads**: competition narrows bid-ask. 3) **Price discovery**: continuous quotes establish fair value. 4) **Reduce volatility**: absorb temporary imbalances. 5) **Get paid**: through spreads + exchange rebates. **How market makers profit 2026**: 1) **Bid-ask spread**: buy at $100.00, sell at $100.01 = $0.01 profit per share. 2) **Volume**: millions of shares per day = millions in profit. 3) **Exchange rebates**: get paid by exchanges for providing liquidity. 4) **Adverse selection**: profit only when not picked off by informed traders. **Top market makers 2026**: 1) **Citadel Securities** ($7B+ revenue, ~30% of US equity volume). 2) **Virtu Financial** ($1.5B+ revenue, public company). 3) **Jane Street** ($15B+ revenue, ETF specialist). 4) **Susquehanna International** (options market maker). 5) **Optiver** (Dutch options MM). 6) **IMC Trading** (Dutch). 7) **Hudson River Trading**. 8) **DRW Trading** (futures/commodities). **Designated Market Makers (DMMs) on NYSE**: 1) **Citadel Securities**: largest DMM on NYSE. 2) **Virtu Financial**: second largest. 3) **GTS**: significant DMM. 4) **DMM responsibilities**: maintain orderly markets, opening/closing auctions. 5) **DMM benefits**: capital requirements, parking spots on trading floor. **Market making strategies 2026**: 1) **Quote both sides**: bid + offer simultaneously. 2) **Adjust spread**: based on volatility (wider in news, tighter in calm). 3) **Manage inventory**: avoid being too long/short. 4) **Hedge rapidly**: with futures, options, ETFs. 5) **Skew quotes**: adjust based on order flow. 6) **Layer the book**: multiple price levels. **Inventory risk 2026**: 1) **Definition**: risk of accumulating too much of one position. 2) **Example**: Market maker buys 100,000 AAPL at $200. Stock drops to $190 before they can sell. Loss: $1M. 3) **Mitigation**: hedge with options, futures, related stocks. 4) **Why spreads widen in volatility**: protects against inventory risk. 5) **Smart MMs**: predictive hedging. **Adverse selection problem 2026**: 1) **Informed traders**: hedge funds, insider info. 2) **Pick off MMs**: trade against stale quotes. 3) **MM defense**: faster quote updates. 4) **Spread protection**: pad spread for adverse selection cost. 5) **Trade-off**: MMs lose to informed, win from uninformed. **Market making vs HFT 2026**: 1) **Market making**: a strategy (provide quotes). 2) **HFT**: a speed (microseconds). 3) **Many HFT firms do market making**: Citadel, Virtu. 4) **Some do other strategies**: arbitrage, momentum. 5) **Overlap exists**: most modern market makers use HFT tech. **Retail "market making" 2026**: 1) **Limit orders**: technically you provide liquidity. 2) **Get exchange rebates**: through brokers like Interactive Brokers Pro. 3) **Negative commissions**: rare but possible. 4) **Limited scope**: cannot quote both sides like institutional MMs. 5) **Better focus**: directional trading. **How market makers affect retail 2026**: 1) **Tighter spreads**: lower costs for you. 2) **Better fills**: instant execution. 3) **Edge protection**: MMs profit from your "noise" trades. 4) **PFOF**: your retail flow goes to MMs (Robinhood → Citadel). 5) **Competition good**: more MMs = better prices. **Bottom line**: Market makers are essential to modern markets.
