Polymarket fonctionne comme un march\u00e9 de pr\u00e9diction d\u00e9centralis\u00e9 construit sur la blockchain Polygon. Le principe de fonctionnement est relativement simple mais ing\u00e9nieux.<\/p>

Les utilisateurs peuvent acheter et vendre des actions repr\u00e9sentant la probabilit\u00e9 qu’un \u00e9v\u00e9nement futur se produise. Ces actions sont toujours valoris\u00e9es entre 0,00 $ et 1,00 $ en USDC.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Le syst\u00e8me fonctionne sur un mod\u00e8le binaire \u00ab\u00a0Oui\/Non\u00a0\u00bb o\u00f9 chaque paire d’actions est enti\u00e8rement collat\u00e9ralis\u00e9e par 1 USDC. Si vous achetez des actions \u00ab\u00a0Oui\u00a0\u00bb \u00e0 0,60$ et que l’\u00e9v\u00e9nement se produit effectivement, chaque action vous rapporte 1$, soit un b\u00e9n\u00e9fice de 0,40$ par action. \u00c0 l’inverse, si l’\u00e9v\u00e9nement ne se produit pas, vos actions deviennent sans valeur.<\/p>

L’architecture d\u00e9centralis\u00e9e de Polymarket pr\u00e9sente plusieurs avantages par rapport aux march\u00e9s de pr\u00e9diction traditionaux. Les utilisateurs ne parient pas contre \u00ab\u00a0la maison\u00a0\u00bb mais contre d’autres utilisateurs de la plateforme. Cette approche peer-to-peer permet aux traders de vendre leurs actions avant la r\u00e9solution de l’\u00e9v\u00e9nement. Offrant, ainsi, la possibilit\u00e9 de s\u00e9curiser des profits ou de limiter les pertes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

L’histoire de Polymarket est indissociable de celle de son fondateur, Shayne Coplan. N\u00e9 en 1998, Coplan a \u00e9tudi\u00e9 l’informatique \u00e0 l’Universit\u00e9 de New York avant d’abandonner ses \u00e9tudes pour se consacrer aux cryptomonnaies et aux march\u00e9s pr\u00e9dictifs. D\u00e8s 2014, alors qu’il n’\u00e9tait encore qu’adolescent, il avait particip\u00e9 \u00e0 l’ICO<\/a> d’Ethereum.<\/p>

Coplan s’est inspir\u00e9 des th\u00e9ories de l’\u00e9conomiste Friedrich Hayek sur les syst\u00e8mes d’information d\u00e9centralis\u00e9s. Il a \u00e9galement \u00e9tudi\u00e9 les travaux de Robin Hanson sur la Futarchie. C’est ainsi qu’il a fond\u00e9 Polymarket en 2020. L’entrepreneur reconna\u00eet lui-m\u00eame que les d\u00e9buts ont \u00e9t\u00e9 difficiles. En 2020, il \u00e9tait \u00e0 court d’argent. Il vendait les meubles de son appartement du Lower East Side pour payer son loyer. Il dirigeait l’entreprise depuis son bureau de salle de bain improvis\u00e9.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Gr\u00e2ce \u00e0 sa t\u00e9nacit\u00e9, Coplan a r\u00e9ussi \u00e0 lever 250 000 dollars lors d’un premier tour de financement. Puis 500 000 dollars suppl\u00e9mentaires pendant la pand\u00e9mie de COVID-19. Blake Robinson de BlockTower Capital se souvient de cette \u00e9poque : \u00ab\u00a0Il m’a dit que Polymarket allait faire de lui un milliardaire, et je l’ai totalement cru\u00a0\u00bb. Cette pr\u00e9diction s’est av\u00e9r\u00e9e exacte en octobre 2025, lorsque Intercontinental Exchange (ICE), la soci\u00e9t\u00e9 m\u00e8re du New York Stock Exchange, a investi 2 milliards de dollars dans Polymarket, valorisant l’entreprise \u00e0 8 milliards de dollars.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Le parcours de Polymarket n’a pas \u00e9t\u00e9 sans emb\u00fbches, particuli\u00e8rement sur le plan r\u00e9glementaire. En janvier 2022, la Commodity Futures Trading Commission (CFTC) a inflig\u00e9 une amende de 1,4 million de dollars \u00e0 la plateforme pour avoir propos\u00e9 des d\u00e9riv\u00e9s non enregistr\u00e9s aux utilisateurs am\u00e9ricains. Cet accord a contraint Polymarket \u00e0 bloquer l’acc\u00e8s aux utilisateurs am\u00e9ricains et \u00e0 nommer J. Christopher Giancarlo, ancien commissaire de la CFTC, comme pr\u00e9sident de son conseil consultatif.<\/p>

Les probl\u00e8mes r\u00e9glementaires ont resurgi de mani\u00e8re spectaculaire en novembre 2024, quelques jours apr\u00e8s l’\u00e9lection pr\u00e9sidentielle am\u00e9ricaine. Le FBI a perquisitionn\u00e9 l’appartement de Shayne Coplan \u00e0 Manhattan, saisissant son t\u00e9l\u00e9phone et ses appareils \u00e9lectroniques dans le cadre d’une enqu\u00eate. Les autorit\u00e9s soup\u00e7onnaient que Polymarket continuait \u00e0 accepter des utilisateurs am\u00e9ricains contournant les restrictions g\u00e9ographiques.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Cette controverse a pris une dimension politique lorsque Coplan a qualifi\u00e9 l’enqu\u00eate de \u00ab\u00a0repr\u00e9sailles politiques\u00a0\u00bb de la part de l’administration sortante. Cependant, l’enqu\u00eate a \u00e9t\u00e9 officiellement close en juillet 2025. Co\u00efncidant avec l’arriv\u00e9e d’une nouvelle administration jug\u00e9e plus favorable aux cryptomonnaies. Donald Trump Jr. a m\u00eame rejoint le conseil consultatif de Polymarket, et le fonds 1789 Capital est entr\u00e9 au capital de l’entreprise.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

L’\u00e9lection pr\u00e9sidentielle am\u00e9ricaine de 2024 a marqu\u00e9 un tournant d\u00e9cisif pour Polymarket. La plateforme a g\u00e9n\u00e9r\u00e9 plus de 3,3 milliards de dollars de volumes uniquement sur cette course. Cet \u00e9v\u00e9nement est devenu le plus important de son histoire. Ce succ\u00e8s a propuls\u00e9 Polymarket sur le devant de la sc\u00e8ne m\u00e9diatique internationale et a d\u00e9montr\u00e9 le potentiel des march\u00e9s pr\u00e9dictifs d\u00e9centralis\u00e9s.<\/p>

La pr\u00e9cision des pr\u00e9dictions de Polymarket a particuli\u00e8rement impressionn\u00e9. Contrairement aux sondages traditionnels qui donnaient une course serr\u00e9e entre Donald Trump et Kamala Harris, Polymarket pr\u00e9disait une victoire de Trump avec 66% de probabilit\u00e9 la veille de l’\u00e9lection. Cette pr\u00e9diction s’est r\u00e9v\u00e9l\u00e9e exacte, validant l’efficacit\u00e9 des march\u00e9s pr\u00e9dictifs par rapport aux m\u00e9thodes de sondage conventionnelles.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Un aspect particuli\u00e8rement m\u00e9diatis\u00e9 de cette \u00e9lection a \u00e9t\u00e9 la participation d’un trader fran\u00e7ais. Surnomm\u00e9 \u00ab\u00a0Th\u00e9o\u00a0\u00bb, il a mis\u00e9 environ 70 millions de dollars sur la victoire de Trump et a empoch\u00e9 un b\u00e9n\u00e9fice de 85 millions de dollars. Cette op\u00e9ration spectaculaire a soulev\u00e9 des questions sur la possibilit\u00e9 de manipulation des march\u00e9s, bien que Polymarket ait affirm\u00e9 n’avoir trouv\u00e9 aucune preuve de tentative de manipulation.<\/p>

L’impact de cette \u00e9lection sur Polymarket s’est ressenti bien au-del\u00e0 des volumes de trading. Le nombre d’utilisateurs actifs mensuels a atteint un pic de plus de 191 000 en octobre 2024. Cependant, apr\u00e8s l’\u00e9lection, les volumes ont chut\u00e9 drastiquement, divis\u00e9s par trois, soulevant des questions sur la capacit\u00e9 de la plateforme \u00e0 maintenir son activit\u00e9 en dehors des \u00e9v\u00e9nements majeurs.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
