Shopify shares closed at $170.85 on October 9 after a strong seven-session advance, yet the stock's next-twelve-month price-to-earnings ratio had fallen to about 82 times from roughly 95 times in September 2025. The reason was not a cheaper share price. Forward earnings estimates rose faster than the stock.
How a rising stock can get cheaper on forward earnings
A forward P/E divides today's share price by estimated earnings over the next 12 months. The multiple can fall when analysts lift profit forecasts more quickly than the share price rises. It can also decline as the 12-month window rolls away from lower-earning quarters and includes later periods with higher expected profit.
The source reported next-twelve-month normalized EPS near $2.10, up from about $1.70 at the end of 2025, while Shopify's share price rose only about 6% over that shorter period. It also reported that consensus 2027 revenue estimates had increased by nearly 15% from their September 2025 level.
The operating results support higher estimates
Shopify reported second-quarter 2026 revenue growth of 34%, or 33% in constant currency, and an 18% free-cash-flow margin. Gross merchandise volume, which measures the value of orders processed through the platform, also grew by more than 30%.
Management guided third-quarter revenue to a low-thirties percentage increase and free-cash-flow margin to the high teens or low twenties. Those targets explain why investors are focused on the November 3 report: the current valuation assumes that growth and cash conversion remain unusually strong.
Forward and trailing P/E tell different stories
The source put Shopify's trailing GAAP P/E near 115 times, up from 83 times, because reported diluted EPS declined over the measured period. Its forward calculation used normalized earnings, which exclude some investment gains and losses. Investors should not compare those two multiples as if they used the same earnings definition.
The lower forward P/E therefore represents estimate growth, not a low absolute valuation. At 82 times expected earnings, a small change in the growth outlook can still produce a large change in the share price.
What could justify the premium
Shopify can support the multiple if merchant activity stays strong, larger brands continue migrating to the platform and incremental revenue produces durable cash flow. AI-enabled commerce tools may strengthen the platform's value, but investors should judge that claim through merchant adoption, revenue growth and margins rather than product language alone.
The downside case is equally clear. If third-quarter revenue lands below the low-thirties guidance range or the free-cash-flow margin slips below the guided band, analysts may reduce estimates. A lower earnings denominator would push the P/E back up unless the share price falls.
BTI's conclusion is that Shopify became less expensive relative to rising forecasts, not inexpensive. The November report must show that estimate growth is being earned through revenue and cash flow rather than simply assumed.
