The [[Ansari X PRIZE|Ansari XPRIZE]] for Suborbital Spaceflight was the first prize from the foundation. It successfully challenged teams to build private spaceships capable of carrying three people and fly two times within two weeks to open the space frontier. The first part of the Ansari XPRIZE requirements [[SpaceShipOne flight 15P|was fulfilled]] by [[Mike Melvill]] on September 29, 2004, On [[SpaceShipOne]], a spacecraft designed by [[Burt Rutan]] and financed by [[Paul Allen]], co-founder and former CEO of Microsoft. On that ship, Melvill broke the 100-kilometer (62.5&nbsp;mi) mark, internationally recognized as the boundary of [[outer space]]. [[Brian Binnie]] [[SpaceShipOne flight 17P|completed the second part]] of the requirements on October 4, 2004, winning the prize. As a result, US$10 million was awarded to the winner, but more than $100 million was invested in new technologies in pursuit of the prize.

Awarding this first prize gave XPRIZE as much publicity as the winners themselves. After the 2004 success there was ample media coverage to afford both Scaled Composites and XPRIZE additional support for them to expand and continue to pursue their aims. Following this early success several other XPRIZES were announced.

The Ansari XPRIZE won the [[Space Foundation]]'s [[Space Foundation#Douglas S. Morrow Public Outreach Award|Douglas S. Morrow Public Outreach Award]] in 2005. The award is given annually to an individual or organization that has made significant contributions to public awareness of space programs.<ref>{{cite web|url=http://www.nationalspacesymposium.org/symposium-awards |title=Symposium Awards &#124; National Space Symposium |date=February 3, 2009 |access-date=January 31, 2012 |url-status=usurped |archive-url=https://web.archive.org/web/20090203060101/http://www.nationalspacesymposium.org/symposium-awards |archive-date=February 3, 2009 }}</ref>

The participants of this competition developed robotic systems that allow operators to see, hear, and interact with a remote environment in a way that feels as if they are truly there. On the other hand, people in the remote environment were given the impression that the operator was present inside the avatar robot. At the competition finals, held in November 2022 in Long Beach, CA, USA, the avatar systems were evaluated on their support for remotely interacting with humans, exploring new environments, and employing specialized skills.<ref>{{cite arXiv|last1=Behnke |first1=Sven |last2=Adams |first2=Julie A. |last3=Locke |first3=David |title=The $10 Million ANA Avatar XPRIZE Competition Advanced Immersive Telepresence Systems |date=2023 |class=cs.RO |eprint=2308.07878}}</ref>

====2006–2013 Archon Genomics XPRIZE====
{{main|Archon X Prize}}
The Archon Genomics XPRIZE, the second XPRIZE to be offered by the foundation, was announced on October 4, 2006. The goal of the Archon Genomics XPRIZE was to greatly reduce the cost and increase the speed of [[human genome]] sequencing to create a new era of personalized, predictive, and preventive medicine, eventually transforming medical care from reactive to proactive. The $10 million prize purse was promised to the first team that can build a device and use it to sequence 100 human genomes within 10 days or less, with an accuracy of no more than one error in every 100,000 bases sequenced, with sequences accurately covering at least 98% of the genome, and at a recurring cost of no more than $1,000 per [[genome]].

If more than one team attempted the competition at the same time, and more than one team fulfilled all the criteria, then teams would have been ranked according to the time of completion. No more than three teams would have been ranked and would have shared the purse in the following manner: $7.5 million to the winner and $2.5 million to the second place team if two teams were successful, or $7 million, $2 million and $1 million if three teams are successful.

Actual competition events were originally scheduled to occur twice a year, with all eligible teams given the opportunity to attempt, starting at precisely the same time as the other teams. This was changed to a single competition scheduled for September 5, 2013, to October 1, 2013, which was canceled on August 22, 2013. The CEO articulated the rationale for the change, "companies can do this for less than $5,000 per genome, in a few days or less – and are moving quickly towards the goals we set for the prize. For this reason, we have decided to cancel an XPRIZE for the first time ever."<ref>{{cite news | work = Huffington Post | date=August 22, 2013 | author= Peter Diamandis | title=Outpaced by Innovation: Canceling an XPRIZE |url=https://www.huffingtonpost.com/peter-diamandis/outpaced-by-innovation-ca_b_3795710.html}}</ref> A public debate concerning the validity and potential implications of the cancellation was published March 27, 2014.<ref name="debate">{{cite web |url=http://genomics.xprize.org/blog/2014/03/27/cancellation-archon-genomics-xprize-public-debate

====2007–2018 Google Lunar XPRIZE====
{{main|Google Lunar X Prize}}
The Google Lunar XPRIZE was introduced on September 13, 2007. The goal of the prize was similar to that of the Ansari XPRIZE, to inspire a new generation of private investment in space exploration and technology. The challenge called for teams to compete in successfully launching, landing, and operating a rover on the [[lunar surface]]. The prize would award $20 million to the first team to land a rover on the Moon that successfully roved more than 500 meters and transmitted back high-definition images and video. There was a $5 million second prize, as well as $5 million in potential bonus prizes for extra features such as roving long distances (greater than 5,000 meters), capturing images of man-made objects on the Moon, or surviving a lunar night.

On January 23, 2018, the prize ended when no team could schedule, confirm, and pay for a launch attempt. The XPRIZE Foundation announced that "no team would be able to make a launch attempt to reach the Moon by the March 31, 2018 deadline... and the US $30 million Google Lunar XPRIZE will go unclaimed."<ref name=sn20170123>{{cite news |last=Foust|first=Jeff |url=http://spacenews.com/google-lunar-x-prize-to-end-without-winner/ |title=Google Lunar X Prize to end without winner |work=[[SpaceNews]] |date=January 23, 2018}}</ref><ref>{{cite web |title=AN IMPORTANT UPDATE FROM GOOGLE LUNAR XPRIZE |date=January 23, 2018 |publisher=XPRIZE Foundation |url=https://lunar.xprize.org/news/blog/important-update-google-lunar-xprize}}</ref>
