Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based CompensationWe issue stock-based incentive awards to our eligible employees under the 2019 Stock Incentive Plan ("2019 Plan") and to our eligible non-employee Directors under a Director Deferred Stock Ownership Plan. The 2019 Plan permits the granting of incentive stock options, nonqualified stock options, stock appreciation rights, performance stock, restricted stock and other stock-based awards.Total stock-based compensation expense primarily related to restricted stock and unit awards was $48 million and $143 million for the three and six months ended June 30, 2022, respectively, and $31 million and $50 million for the three and six months ended June 30, 2021, respectively. For the three and six months ended June 30, 2022, stock-based compensation expense primarily related to the early vesting of IHS Markit equity awards as a result of employee terminations and restructuring efforts. During the six months ended June 30, 2022, the Company granted 0.7 million shares of restricted stock and unit awards, which had a weighted average grant date fair value of $389.62 per share. Total unrecognized compensation expense related to unvested restricted stock and unit awards as of June 30, 2022 was $264 million, which is expected to be recognized over a weighted average period of 1.8 years.
