3 U.S. Market Platform Stocks Worth Watching as Volatility Lifts Trading Activity

AI and tech stocks have just taken a sharp hit, politics are tilting toward tighter rules, and traders are suddenly bracing for more Fed rate hikes. Volatility itself has become the story. When markets lurch, investors who understand how exchanges and trading platforms react can often spot underappreciated openings. This piece walks through three U.S. market infrastructure stocks exposed to these shocks and why they may deserve a closer look right now.

The stocks highlighted below are just a sample, and the full screen surfaced 32 more U.S. market infrastructure companies with similarly detailed stories that are not covered here. To identify and analyze the highest conviction volatility and derivatives platform ideas for your watchlist, head straight into the U.S. Volatility and Derivatives Market Platforms screener.

Intercontinental Exchange (ICE)

Intercontinental Exchange is one of the purest plays in this screener on how volatility turns into fees. It sits where futures, options, clearing and data meet when trading activity spikes across markets.

Intercontinental Exchange generates most of its US$13.6b revenue from Exchanges at about US$8.9b, with Mortgage Technology at roughly US$2.2b and Fixed Income and Data Services near US$2.6b. The stock’s value sits around US$97.2b.

"The continued expansion and integration of ICE's global electronic trading platforms across asset classes, including growing futures and options open interest and higher NYSE transaction activity, points to further scaling of transaction revenues and operating leverage feeding into earnings."

The real swing factor is how one large investment push feeds through to costs now and to potential margin strength when volatility bites again.

When that investment spend starts to bite less into margins, read the full narrative for Intercontinental Exchange to see how Intercontinental Exchange could be repricing its volatility leverage.

Piper Sandler Companies (PIPR)

Piper Sandler Companies is an investment bank and institutional broker that connects large investors, corporations, and public entities to equity, fixed income, and over the counter derivatives tied to U.S. market volatility. It generated about US$2.1b from brokerage activities, almost entirely in the U.S., and has a market value near US$4.5b.

Piper Sandler gives you direct exposure to institutional trading, hedging, and deal flow that often picks up when markets swing, backed by a 20.5% ROE and high-quality earnings but funded entirely through external liabilities. The key question is what happens if that volatility driven revenue mix collides with a more expensive funding base.

That funding squeeze is the real swing factor, so check the 3 key rewards and 1 important warning sign to see how Piper Sandler’s volatility engine interacts with that balance sheet.

Marex Group (MRX)

Marex Group plugs straight into this volatility focused theme, since its whole platform is built around clearing, market making and hedging services that tend to get busier when clients need to trade more, manage risk faster and move exposure across commodities, financial contracts and digital assets.

Marex Group runs a broad trading infrastructure platform across commodities, financial markets and digital assets, providing clearing, execution, liquidity and hedging tools that tie directly into derivatives and volatility flows. The business carries a market value of about US$4.7b.

"Expansion of Marex Group’s higher margin infrastructure activities, with clearing, prime services and financing now contributing roughly 70% of group profitability and around $150m of the $188m profit before tax increase between 2023 and 2025, supports the view that a richer mix of recurring revenue can continue to lift adjusted margins and earnings levels."

The real hinge for Marex Group is how that higher margin mix behaves if one pressure point suddenly changes the cost of keeping those markets open.

That cost pressure is exactly what the full narrative for Marex Group unpacks, revealing how Marex Group’s margin mix could accelerate or stall as liquidity stress and client risk appetite shift.
