The bond, which will pay a fixed gross rate of interest of 6.50% a year until 2022, was on sale from 24 April to 6 May.
David Armstrong, the club's chief executive, said the response had been "very positive" and offered stability for the club's future.
Wasps play in the Aviva Premiership at the Ricoh Arena in Coventry.
The club moved to the 32,600-seater stadium from Adams Park, High Wycombe, in December 2014.
"The funds raised [from bond sales] will enable us to restructure our balance sheet and pay down our existing debt, including the loans we acquired with the Ricoh Arena," Mr Armstrong said.
"We now have a solid foundation for the long-term future of the club and look forward to the future with confidence."
Minimum initial investment in the bond was £2,000 - which, like any investment, has risks involved. There are plans for it to be tradable on the London Stock Exchange's Order Book for Retail Bonds.
The bonds will be guaranteed by the two key operating companies, Wasps Holdings and Arena Coventry Ltd, including the Ricoh Arena.
Interest will be paid on 13 November and 13 May in each year with the investment due to be paid back in full on 13 May, 2022. Trading in the bonds is earmarked to start on 14 May.

Foundation surgeon Peter Grossman carried out the reconstruction surgery.
Aisha was widely photographed and filmed earlier this week receiving the Enduring Heart award at a benefit ceremony staged by the foundation.
She was given the award by California first lady Maria Shriver, the wife of California Governor Arnold Schwarzenegger.
"This is the first Enduring Heart award given to a woman whose heart endures and who shows us all what it means to have love and to be the enduring heart," Ms Shriver said.
Aisha - whose surname has not been revealed - replied: "Thank you so much."
The 18-year-old was reportedly given away by her family in childhood as a "blood debt" and was subsequently married to a Taliban fighter.
His family abused her and she ran away but was recaptured and mutilated by her husband.
Aisha's case has been used in the West to illustrate the fear of what will happen if US, British and other international forces leave prematurely.
Some critics questioned the tone of the Time cover arguing that it was using emotional blackmail and gender politics to justify continued US involvement in Afghanistan.
