Tesla Merger Talk Could Lift S&P Global Stock And ETF Trading Plays

A potential Tesla and SpaceX merger suddenly turns index plumbing into the main story, not a footnote. If a combined giant reshapes the S&P 500, the real action could sit in the machinery that tracks, packages, and trades that benchmark. That is where index and ETF infrastructure players come in. This article walks through three stocks exposed to this news and how they might benefit if passive flows start to realign.

The stocks covered below are just a first pass, and the full screen surfaced 24 more US index and ETF infrastructure providers with equally compelling stories that are not discussed here. To identify and analyze the highest conviction ways to play this potential Tesla and SpaceX index reshuffle, go straight to the US Index & ETF Infrastructure Providers screener.

S&P Global (SPGI)

S&P Global is the index and data powerhouse behind many of the very benchmarks passive funds track, so any rethink of the S&P 500 feeds straight into its world. That is exactly what SakuraCoffee, an investor in the Simply Wall St Community, focuses on in this view.

"At the same time, there is a structural concern weighing on sentiment: the potential impact of AI on S&P Global’s data and analytics franchises."

How that one pressure plays out could end up mattering more for future pricing power and profitability than any single index reshuffle.

S&P Global is a US$135.8b index and data heavyweight. It earns US$5.2b from Market Intelligence, US$5.1b from Ratings, US$2.4b from Energy and US$2.1b from Indices, which directly ties the business to ETF and benchmark-linked activity that the screener is built around.

That pressure point is only one piece of the story, and the full narrative for S&P Global shows how S&P Global could still compound its influence as index plumbing evolves.

Interactive Brokers Group (IBKR)

Interactive Brokers Group plugs straight into the US Index & ETF Infrastructure Providers theme because its electronic brokerage platform sits where index-driven investors actually trade, and the analyst consensus Narrative on Simply Wall St focuses on how that position ties into client activity and revenue.

Interactive Brokers Group runs an automated global brokerage platform that earns about US$7.1b from brokerage services, connecting institutions and individuals to index, ETF, and other markets. The stock’s roughly US$138.4b market cap reflects its scale in that trading infrastructure.

"The successful addition of client accounts, which rose 34% year over year in Q2 2026, and growing daily average revenue trades provide a larger and more active user base that can translate into higher transaction volume and related fee revenue for Interactive Brokers Group."

What happens if one quiet assumption about how much those active clients trade around big index events starts to shift?

If that trading intensity around index moves is what you care about, read the full narrative for Interactive Brokers Group to see how Interactive Brokers Group could experience an acceleration in that activity.

Lincoln International (LCLN)

Lincoln International is an independent advisory firm that helps investors and corporations with M&A deals and portfolio valuations. This keeps it close to the capital markets plumbing that index and ETF providers rely on. It generates about US$796 million from Investment Banking Advisory and US$196 million from Valuations and Opinions, with a market value of roughly US$2.7 billion.

Lincoln International connects institutional investors and corporates to capital raising, dealmaking, and frequent portfolio valuations that inform indices and fund reporting. The firm trades on a low 8.6x P/E with ROE above 26%. Investors watching how record advisory revenue and a growing backlog reshape margins and earnings may care what happens if a single key assumption breaks.
