10 large 401(k) plans sponsored from Illinois reported 1,000 to 4,999 participants on their latest Form 5500 and have a page here. All of them are listed here, ranked by active participants.

Active participants means people still building up a balance, which is the count Form 5500 reports separately from total participants.

The plans

Ranked by active participants, the same order the site publishes plan pages in. Assets are Schedule H total assets at end of plan year, in USD. Cost per participant is plan-paid administrative expense, and a filing that itemized none says so instead of showing a zero.
