The former chancellor, sacked from the Government by Theresa May when she became Prime Minister in July, has been paid more than £80,000 a go for some of his recent speaking engagements.
The figures, revealed in the latest register of MPs' financial interests, show Mr Osborne expects to receive payments of £81,174 and £60,578 from JP Morgan for two speeches delivered at the start of October - a total of seven hours work.
Mr Osborne signed up to the Washington Speakers' Bureau after he left Government and he is due to be paid £80,240 from Palmex Derivatives for a speech in New York he gave on October 27 - which he recorded as a total of two hours work.
Mr Osborne also expects to be paid £69,992 by the Securities Industry and Financial Markets Association (SIFMA) in return for a speech on September 27 and October 18.
Meanwhile, the former chancellor is due to be paid £28,454 for a speech on October 17 from the Hoover Institution at Stanford University.
The latest register of interests also show Michael Bloomberg paid for Mr Osborne and his wife to attend a dinner for the former mayor of New York City in Paris.
The value of the travel, accommodation and dinner in the middle of October was estimated at £4,086.
Mr Osborne has previously disclosed two helicopter trips in the register of interests: one in November 2015 to the Forest of Dean Conservative dinner and another to Ripon North Conservatives' Summer Reception in July this year.
