AI fever is spilling out of chip stocks and into the plumbing of the market itself, as trading venues, data vendors and brokers feel the ripple effects of CoreWeave’s 168% Q3 revenue jump, Nvidia headlines and Anthropic’s giant IPO plan. That mix of hype and scrutiny is pulling fresh volume, fees and volatility into market-structure players. This article walks through 3 stocks exposed to that news and explains why they may warrant closer attention at this time.
The three stocks below are just a starting sample. The full screen surfaced 12 more listed market-structure and trading-infrastructure providers with equally compelling narratives that are not covered here.
Head straight into the Listed Market-Structure & Trading-Infrastructure Providers screener to identify, analyze, and size up the highest-conviction ideas for your own watchlist.
Bolsas y Mercados Argentinos (BASE:BYMA)
Bolsas y Mercados Argentinos runs Argentina’s main exchange and market plumbing, so it sits squarely in this market-structure theme and, as the analyst consensus Narrative on Simply Wall St argues, its future is tied to how liquidity and product depth evolve from here.
"The planned launch of a local market maker program and the first ETF tracking the S&P Merval Index is aimed at improving liquidity in local equities. This can lift equity trading volumes, support higher exchange revenue and improve operating leverage."
What happens if a single assumption about how that liquidity builds over time proves too optimistic or too cautious for Bolsas y Mercados Argentinos?
Bolsas y Mercados Argentinos operates Argentina’s main stock exchange and related post trade services, connecting local investors and issuers, and carries a market cap of about ARS1,509.9b.
If that liquidity path matters to you, read the full narrative for Bolsas y Mercados Argentinos and see how different volume scenarios could reshape fees, multiples and long term upside risk.
flatexDEGIRO (XTRA:FTK)
flatexDEGIRO is closely linked to the Listed Market-Structure & Trading-Infrastructure Providers theme through its online brokerage and securities IT platforms across Europe, with a market value of about €2.4b.
The analyst consensus Narrative on Simply Wall St presents flatexDEGIRO as a pure play on how active European investors want to trade, save and move money through low friction platforms.
"The strong inflow of new and existing customer funds is still visible, with assets under custody now above €100b and over €5b of fresh money added in the six months to July 2026, which supports future revenue on both transaction and asset based income lines."
The key issue is how one unresolved pressure on its business model will influence the balance between customer growth, pricing power and long term margins.
That pressure point on flatexDEGIRO’s model is the real story, and the full narrative for flatexDEGIRO shows whether accelerating customer inflows can offset it.
GMO internet group (TSE:9449)
GMO internet group plugs into this market-structure theme from the plumbing side, providing domains, hosting, payment rails and online financial services that can support trading and data platforms behind the scenes.
GMO internet group runs a broad suite of online infrastructure and financial services, with internet infrastructure contributing about ¥186.8b, internet finance ¥43.7b, security ¥23.5b, and advertising and media ¥34.7b, against a market value of roughly ¥297.0b.
"The launch and growth of the net security GMO project, including high unit price penetration testing and cryptographic services, aim to capture rising cybersecurity demand and support higher margin recurring revenue."
What really shifts the story for GMO internet group is how one less visible funding and risk constraint shapes the payoff from those higher margin ambitions.
That funding constraint is the crux, and the full narrative for GMO internet group shows how GMO internet group could still turn its security push into accelerating, higher quality earnings power.
