When Do Investment Banking Internships Open? The Verified Timeline

Most recruiting-timeline advice online is guesswork, recycled year after year with the dates quietly wrong. So we checked. Every date in this post was verified in September 2026 against a primary source — the bank's own careers page, a university careers office, or dated industry reporting — and where something could not be verified, we say so rather than guessing.

The one-line summary: US investment banking internship recruiting now starts in the autumn of sophomore year, roughly eighteen months before the internship itself. If you are waiting for junior year to think about this, the window is not "approaching" — it has already opened.

Which cycle is open right now

As of September 2026, two cycles are running at once.

Summer 2027 (current juniors) is closing out its long tail. Goldman Sachs's 2027 Summer Analyst Program still showed applications open for select businesses in mid-September 2026. Adventis's tracker of 180 firms showed 113 firms had posted 2027 applications by 1 September 2026, with 67 still to come — mostly middle-market and regional names. The bulge brackets and elite boutiques, though, opened their flagship windows back in the winter and largely filled their classes by late spring.

Summer 2028 (current sophomores) has already begun. Evercore opened its US 2028 Summer Analyst applications in early September 2026, with a mid-November deadline — roughly four months earlier than its own previous two cycles, both of which opened in early January. Third-party trackers had projected Evercore would not open until December or January. It beat its own precedent by a full season, and as of mid-September it was the only major firm with 2028 applications live.

That last point is the one to internalise: the timeline is not just early, it is still moving earlier, and the projections keep being beaten.

How the last full cycle actually ran

The summer 2027 cycle is the most recent one with a complete, verifiable record. Here is how it unfolded:

• November 2025 — the early movers. Houlihan Lokey, Perella Weinberg, Rothschild and Stifel posted their first 2027 applications, per Adventis's tracker. Houlihan Lokey's New York posting went live on 20 November 2025, explicitly open to sophomores — about eighteen months before the internship would begin.
• December 2025 — the wave builds. J.P. Morgan, Moelis, Lazard and Citi posted their first 2027 applications. eFinancialCareers reported on 12 December 2025 that RBC, Rothschild, Perella Weinberg and Raine were already open — while noting that neither Goldman Sachs nor JPMorgan had their main postings live yet.
• January to March 2026 — the bulge-bracket flagship windows. Morgan Stanley's investment banking summer analyst application ran from 1 January to 15 February 2026, reviewed, in the bank's own words, "on a rolling basis". Evercore's US window ran from early January to early February. JPMorgan's main global investment banking application opened around 1 March and ran to 1 July 2026 — again rolling.

"Rolling basis" is doing a lot of work in that list. It means applications are read as they arrive, and offers go out while the window is still open. Submitting on the deadline is not the same as submitting on time.

This is sophomore-year recruiting — and it has been building for a decade

Match those dates against a university calendar and the conclusion is unavoidable: the process starts in sophomore autumn and peaks in sophomore winter. Yale's careers office says exactly that — banks recruit for junior-summer internships about a year and a half out, beginning during sophomore year, and some boutiques may open even earlier.

It was not always like this, and the one attempt to stop it failed. In 2018, Goldman Sachs and JPMorgan publicly announced they would stop interviewing sophomores for certain internships, after offers had crept to fifteen or sixteen months ahead of start dates. That retrenchment did not hold. The sophomore timeline is now the institutional norm — published as standard guidance by university careers offices, not whispered as a loophole.

For summer 2028, Adventis currently projects Goldman Sachs, Morgan Stanley and J.P. Morgan will post their first applications in December 2026 or January 2027. Treat that as a forecast, not a promise — it matches last cycle's pattern, but Evercore just showed how fast a bank can move ahead of every projection.

The year before the applications: insight programmes

The applications are not even the start any more. Banks now run structured pipeline programmes for first-years and sophomores that sit a year or more ahead of the internship process:

• Goldman Sachs Possibilities Series — an official programme for first-year undergraduates; the most recent edition was restricted to the class of 2029, with a 1 March 2026 application deadline. Goldman frames it as learning and networking rather than a guaranteed pathway — but it puts you on the radar a full cycle early.
• Citi Early ID — sophomore-only programmes for investment banking and sales & trading ran in autumn 2025, applications closing 7 November 2025, explicitly feeding the summer 2027 interview process.
• Jefferies Insight Days — class-of-2028 events with a 30 November 2025 application deadline, described by the firm as giving insight into its 2027 recruiting processes.
• Houlihan Lokey sophomore events — in-office sessions in December 2025, tied to its 2027 summer analyst recruiting.

Details like eligibility and deadlines roll over every year — university careers offices track the current editions — but the shape is stable: the banks are meeting their future analyst class in freshman and sophomore year, before a single application is read.

If you think you are already late

Two honest things at once.

First, the verified data says the cycle has a long tail: as of 1 September 2026, 67 of the 180 firms on Adventis's tracker had still not posted summer 2027 applications. Middle-market and regional firms keep opening well into the autumn of junior year, months after the bulge brackets have finished. Late does not mean over.

Second, we will not pretend to give you verified dates for off-cycle or lateral routes, because our research could not verify any — and made-up specifics are exactly the problem with most recruiting content. What is in your control is readiness: the firms still to open will move quickly when they do, and the candidates who win those seats are the ones who were prepared before the posting appeared, not the ones who started preparing when it did.

What this means for your calendar

• First year: learn the industry, build the GPA, and apply to first-year programmes like the Possibilities Series when the current edition opens.
• Sophomore autumn: applications for insight and early-ID programmes close around November. Networking should already be running. Watch for early movers posting internship applications from November onwards — and expect more banks to pull forward, as Evercore just did.
• Sophomore winter: the flagship windows historically open around January. Rolling review means the day a window opens matters more than the day it closes. Your technicals, your CV and your story need to be interview-ready before this, not polished during it.
• Junior autumn: the long tail of middle-market and regional firms is still open — if you are here without an offer, this is where the remaining at-bats are.

The uncomfortable truth underneath all the dates: by the time most people start preparing, the people they are competing with have been preparing for a year. The timeline is not fair, and it is not slowing down. But it is knowable — and now you know it.

All dates verified September 2026 against the linked sources. Banks change their timelines every cycle — always confirm the current window on the firm's own careers page before relying on it.
