We note your response to comment 2, however we continue to believe that you should disclose the number or percentage of your customers that are Instacart+ members for prior periods, particularly given your disclosure comparing the changes in the percentage of your total GTV generated from orders from Instacart+ members over time. Where you include such disclosure, you may also disclose how the changes in the percentage of customers that are Instacart+ members may not necessarily be indicative of overall trends, performance, or growth, to the extent accurate 4. Please tell us why you believe it is appropriate to highlight a compound annual growth rate for average monthly gross profit of 45% from year 1 to year 3, as you do on page 101. We note that this is largely driven by the 2019 cohort, which is the only cohort included in each of the three years presented. We note that the percentage increase in year 1 to year 2 is significantly larger for the 2019 cohort than other cohorts. Please revise to present a more balanced picture of the changes in average monthly gross profit for your cohorts overall. Market Share among Digital-First Platform, page 154 5.
