This older article suggests a few 100,000s annually is generated to the university from all sports camps (assuming its more now). The final piece of the puzzle is endowed funds and donations. The Hawkeye Wrestling club took in 1.37 million in FY24, though much of this goes to fund Freestyle/elite athletes (at least 790k) https://projects.propublica.org/nonprofits/organizations/237302974/202522879349301472/full. However we don't know what annually operating budget funds come from gifts, endowment or how Hawkeye wrestling club funds may offset some regular operating, etc. I would exclude huge capital gifts for Wrestling only facilities but they should be off-setting some operating from gifts, which would still show up as a budgeted expense in the figures. When put together with camps, media and conference share money, I think we are getting close to breaking even....though only at the absolute top institutions.
To be fair, D1 wrestling is not profitable as the model for profitability is D3 through tuition and enrollment enhancement---see
