She told the BBC she also planned to share the Turner Prize - but felt she could only make such a public proclamation once. "This is something that can happen much more discreetly between the four of us," added Marten.
'Extraordinary range'
Accepting her prize from poet Ben Okri, Marten said she "wasn't expecting" to win and that she could not think of "a more brilliant and exciting shortlist of artists to be part of".Marten, who is from Macclesfield but now lives in London, faced competition from Anthea Hamilton, Michael Dean and Josephine Pryde for the Turner Prize, the aim of which is to "promote public debate around new developments in contemporary art".
Marten was nominated for projects including Lunar Nibs at the 56th Venice Biennale and her solo exhibition Eucalyptus Let Us In at Greene Naftali in New York.
Speaking at the ceremony, she said: "Our global outlook is becoming ever more precarious and from the stripping of arts and creative writing programmes in schools syllabuses to the ever prominence of alt-right groups gaining a very visible and frightening political platform for a xenophobic, homophobic and racist outlook on the world.
"I think as artists today and as people in this environment, we are deeply, deeply privileged to be sitting here, with a community whose lifeblood is a sort of diversity and exuberance."
The runners-up each receive £5,000 prize money.

Addressing the ceremony, Sir Nicholas Serota, outgoing director of the Tate galleries, said: "The strength of the Turner Prize is that encourages us to think about the world in new ways.
"At a time when there are fears that we in the UK may be becoming more insular and more inward-looking as a nation, the Turner Prize reminds us that art opens us to new ideas.
"We need to encourage such openness in a society that faces many challenges." He stressed arts and humanities need to play a central role in the UK education system and should not be "pushed to the margin", adding the arts were "part of our DNA as a nation".
Marten's installations shown at the Tate as part of the Turner Prize exhibition, which runs until January, included works made from cotton buds, marbles, snooker chalk and bicycle chains.
The Tate said that "her collage-like gatherings of objects and images have a playful intent, creating poetic visual puzzles that seem to invite us into a game or riddle".
The jury said her work "is outstanding for its extraordinary range of materials and form" and that they admired its "poetic and enigmatic qualities which reflect the complexities and challenges of being in the world today".
They added that Marten is "making an exceptional contribution to the continuing development of contemporary visual art".
