Foreign buyers have quietly become huge players in US equities, with roughly $942b flowing into American shares and funds over the 12 months to July and a record $426b in Q2 2026 alone. That kind of demand can reshape how custody, clearing, and capital markets infrastructure stocks trade, creating both tailwinds and pockets of risk. This article walks through three stocks exposed to this foreign flow story and explains why each might be worth closer inspection now.
The three stocks covered next are only a starter sample, and the broader screen surfaced another 25 US custody and capital markets infrastructure providers with equally compelling narratives that are not unpacked in this article. To see the full field and quickly identify which businesses best fit your own thesis, head straight to the US Custody and Capital Markets Infrastructure Providers screener.
Virtu Financial is one of the clearest plays on the screener theme, operating in the core infrastructure of equity and ETF trading where foreign flows interact with US market structure.
Virtu Financial earns most of its revenue from Market Making at about US$2.7b, with Execution Services contributing roughly US$667m, and the stock carries a market value near US$8.2b.
“Virtu Financial’s moves into digital assets, including an EU MiCA license and participation in on chain repo, still require meaningful client volumes and fee pools that have not yet materialised. If adoption of these market structures is slower than implied by current expectations, the company may face a drag on returns from underutilised technology investment and limited revenue diversification.”
What really matters next is how one less visible pressure shapes the balance between fresh trading opportunities and the profitability you may be relying on.
That pressure point is exactly what the full narrative for Virtu Financial unpacks, showing where foreign flows could accelerate liquidity while digital bets risk masking Virtu Financial’s core earning power.
WisdomTree gives foreign investors a straightforward way into US equities through its ETFs, which plugs it directly into the cross-border flow story powering this screener and raises a broader question about how its newer digital rails might reshape that role.
“WisdomTree’s early investments in blockchain, tokenization, and stablecoin-powered digital asset infrastructure are enabling new product and revenue streams (such as tokenized funds and scalable net interest income), aligning them with the expanding adoption of digital finance, which is likely to boost both top line and margin expansion.”
