A duopoly is a form of oligopoly where only two companies dominate the market.#

  • Companies in a duopoly tend to compete with each other, reducing the likelihood of monopoly market power.
  • Visa and Mastercard are examples of the duopoly that dominates the payments industry in Europe and the US.
  • One of the disadvantages of duopolies is that consumers have a small choice of products.
  • Another disadvantage of duopolies is that two players can collude and raise prices for the consumer.
