In September 2016, Markel leased the station's broadcast day to former KFNS host Tim McKernan and his company, InsideSTL Enterprises;<ref name="Sales610">"[https://radioinsight.com/headlines/106740/station-sales-week-of-610/ Station Sales Week Of 6/10]", ''RadioInsight''.

As part of the lease arrangement, the station's license was transferred to McKernan Radio Group, LLC, which was 75% owned by Markel and 25% owned by McKernan.<ref name="Sales610"/> In 2018, Randy Markel acquired total ownership under Markel Entertainment LLC. In November 2021, Markel sold all interests in KFNS to Zobrist Media LLC and it remains privately held under principal Dave Zobrist. Markel later cited the pandemic and the loss of sports content to cover as the reason for the sale, and noted in July 2024 he was interested in reacquiring the station since then.<ref>{{Cite web |last=Caesar |first=Dan |date=2024-07-05 |title=Former KFNS owner Randy Markel considers returning despite his losses: Media Views |url=https://www.stltoday.com/sports/column/media-views/former-kfns-owner-randy-markel-considers-returning-despite-his-losses-media-views/article_f64bfb36-3736-11ef-9876-8fd0b7afbed8.html |access-date=2025-03-29 |website=STLtoday.com |language=en}}</ref>

In April 2025, Zobrist announced the sale of a majority stake in the station to Big Toe Media, a consortium that included David Greene and Conrad Thompson. Big Toe's plans include broadening the station's focus to a general interest (and partially [[Brokered programming|brokered]]) [[talk radio]] station discussing "anything except for politics" and changing the station's call sign. Greene stated that he had initially been hired to shop the KFNS intellectual properties to other buyers and, after the most promising prospect dropped out of contention, agreed to buy the station from Zobrist themselves at a greatly discounted rate from its previous sale price.<ref>{{Cite web |date=2025-04-09 |title=New Owners Of KFNS-AM Promise ‘A New Direction’ for St. Louis Talk Radio. |url=https://www.insideradio.com/free/new-owners-of-kfns-am-promise-a-new-direction-for-st-louis-talk-radio/article_891a306c-7698-4fb7-9352-18237a98f073.html |access-date=2025-04-13 |website=Insideradio.com |language=en}}</ref><ref>{{Cite web |date=2025-04-09 |title=KFNS (590 AM) Sold: Longtime St. Louis sports radio station set for rebrand |url=https://www.yahoo.com/news/kfns-590-am-sold-longtime-175817596.html |access-date=2025-04-13 |website=Yahoo News |language=en-US}}</ref>
