=== Data analysis after NASA ===
NASA funding and sponsorship of the program ended on <time datetime="2008-09-30">30 September 2008</time>, but GP-B secured alternative funding from [[King Abdulaziz City for Science and Technology]] in Saudi Arabia<ref name = "Gugliotta2009"/> that enabled the science team to continue working at least through <time datetime="2009-12">December 2009</time>. On <time datetime="2008-08-29">29 August 2008</time>, the 18th meeting of the external GP-B Science Advisory Committee was held at Stanford to report progress. 

The Stanford-based analysis group and NASA announced on <time datetime="2011-05-04">4 May 2011</time> that the data from GP-B indeed confirms the two predictions of Albert Einstein's general theory of relativity.<ref>{{cite web |url=https://news.stanford.edu/2011/05/04/stanfords-gravity-probe-b-confirms-two-einstein-theories/ |title=Stanford's Gravity Probe B confirms two Einstein theories |website=Stanford News |publisher=Stanford University |date=4 May 2011}}</ref> The findings were published in the journal ''[[Physical Review Letters]]''.<ref name=PRL>{{cite journal | author=Everitt | display-authors=etal | date=2011| title=Gravity Probe B: Final Results of a Space Experiment to Test General Relativity| journal=Physical Review Letters| volume = 106 | issue = 22 | page=221101 | doi = 10.1103/PhysRevLett.106.221101 |arxiv =1105.3456 | bibcode=2011PhRvL.106v1101E | pmid=21702590| s2cid=11878715 }}
