How many internships should I apply to? Summer 2027

Every piece of internship advice says to apply to a lot of roles, but a lot is never a number. We counted what is actually open, how much is added each week, and how quickly it closes, so you can set your own.

What we measured

On November 8, 2026, we took every U.S. internship tagged for Summer 2027 on the SimplifyJobs internship tracker, the feed behind Arial's job board: 4,594 postings added since March, 2,173 of them still open. The tracker records the day each posting was added and whether it is still open, so we counted open roles by field, new roles by week, and the share of each week's additions that has since closed. We did the same for the new grad tracker.

How many Summer 2027 internships are open

A few large employers hold a big share of the open roles: TikTok had 153 open Summer 2027 internships, Waymo 56, ByteDance 42, Marvell 41, Booz Allen 38, and NVIDIA 36. Most companies have far fewer: 270 of the 604, 45 percent, had exactly one. The 50 companies with the most open internships hold 44 percent of them; the other 56 percent are spread across 554 smaller employers, so a list of famous names misses most of the market.

How many new internships go up each week, and how fast they close

Additions peaked the week of August 31, at 645, and have held near 265 a week since early October: about 115 in AI, machine learning, and data, 80 in software engineering, 45 in hardware, 15 in product, and 10 in quant. Closings follow fast. More than half of every week's additions from late August through September are already closed, about a third of the internships added the week of October 26 closed within two weeks, and 13 percent of the ones added between November 2 and 7 were already gone by November 8. Between the tracker files of November 6 and November 8, 85 of 2,187 open Summer 2027 internships closed and 62 new ones were added.

New grad roles close even faster

The new grad tracker had 2,694 open U.S. roles at 967 companies on November 8, 981 of them in software engineering, and about 334 new roles went up a week since early October, 135 in software. 71 percent of the new grad roles added between August 1 and October 24 were already closed, against 56 percent of the Summer 2027 internships added in the same weeks.

What that means for how many to apply to

• Apply to every role you fit, not a quota. Even if you fit only a third of the 715 open software engineering internships, that is more than 200 applications.
• Apply within days of a posting going up. Only 19 percent of open Summer 2027 internships went up in the past two weeks, and more than half of the ones added in September are already closed.
• Look past the famous names. More than half of open Summer 2027 internships are at companies outside the 50 biggest posters.
• Keep going. About 265 new internships a week were still going up in early November.

Students are already sending more applications and getting less back. NACE found that the Class of 2025 sent an average of 10 job applications, up from six for the Class of 2024, and received fewer offers. On Handshake, postings fell more than 16 percent between August 2024 and August 2025, while applications per role rose 26 percent.

Let an AI agent apply to jobs for you

Hundreds of applications is where an AI agent that applies to jobs for you earns its place. A typical tech application form asks about 18 questions, and Workday makes you create an account for every employer. On Arial, the job board lists new internships as the tracker adds them, about every two hours, and when you tap Apply on a job hosted on Greenhouse, Ashby, Workday, Oracle, or Indeed, the agent fills in the employer's form from your resume and profile, creates the account a site needs, and submits it. Applying the week a role posts takes a tap instead of an evening. You still choose the roles.

The right number of internship applications is the number of roles you fit, and for most tech students that is more than they send. The roles are there; the hard part is reaching them before they close.
