Which force addresses how easy it is for new competitors to enter the market and threaten incumbents?

• A. Threats of new entrants
• B. Competitive Rivalry
• C. Power of Customers
• D. Substitute Products

Answer: (A)

The main idea here is about how easy it is for new players to come into a market and challenge the firms that are already there. In Porter’s framework this is captured by the Threat of new entrants. When barriers to entry are low—low startup costs, little access to distribution channels, weak brand loyalty, minimal regulation, or little need for specialized assets—new competitors can join quickly and put pressure on prices, margins, and market share. Incumbents may face accelerated price competition, need to invest more to defend their position, or need to innovate faster to maintain their advantage. When barriers are high, new entrants find it harder to compete, and the threat to incumbents is reduced.

To understand why the other forces don’t fit as well: Competitive Rivalry focuses on how intensely existing firms compete against each other rather than on how easy it is for outsiders to enter. Power of Customers looks at how much bargaining power buyers have, which affects margins but not entry barriers themselves. Substitute Products gauge the risk from alternative solutions outside the current market, not the ease of entering the market.

So, the correct concept is the Threat of new entrants, because it directly measures how easily new competitors can enter and threaten incumbents.
