Thanks, Rebecca, and hello, everyone. I hope you had a chance to read my shareholder letter, where I highlighted yet another strong quarter for Instacart. Our performance reinforces how central we are in helping families save time, money and effort when it comes to putting food on the table and the vital role we play in building the technology that will power the future of grocery together with our partners. While this is my last earnings call as Instacart's CEO, I can't imagine a better time to step aside. The strength of our business and the opportunities ahead make me incredibly confident in the future we've built for these companies. It's clear our business is firing on all cylinders. We've extended our supply advantage by building innovative technologies that make our service easier to use and more affordable, while deepening our retail partnerships and helping retailers grow faster. This includes launching personalized shopping services, family accounts, loyalty integrations and digital flyers to higher frequency offerings like our restaurant partnership with Uber Eats and industry-leading $10 minimum basket size for Instacart+ members to get wave delivery fees. Together, our efforts are driving strong user growth and higher order frequency while also delivering better retention, especially among new 2025 customers compared to last year. Paid Instacart+ members are also growing and their engagement as a percent of monthly users continues to deepen, too. We're also fulfilling orders more quickly and accurately, an exceptionally tough challenge when it comes to big basket grocery shopping. This is where our technology, operating scale and data really set us apart, whether it's AI-driven inventory prediction, new personalized replacement models, store planograms or real-time receipt scanning to catch issues, we are relentlessly improving every step of the process from helping you place your order to when it arrives on your doorstep. In addition, experienced shoppers who've completed a median of over 1,000 Instacart orders now shop for nearly 2/3 of our orders. Together, over the past 4 years, these advantages have helped us complete orders approximately 25% faster while achieving all- time highs in sound and fill rates. Fulfilling customers' desire for convenience while ensuring they get more of what they order keeps customers coming back to our service and gives us a strategic advantage that is incredibly hard for competitors to replicate. Another one of our biggest strengths is our interconnected ecosystem. Improvements we make on our marketplace fit directly into our enterprise solutions and vice versa, creating a virtuous cycle. This allows us to offer scalable, flexible tools that help retailers innovate and compete, especially at a time when the rate of technological change is only increasing. This is evident in the velocity at which we're onboarding new storefront partners, and our capabilities are also benefiting big B2B players, too, like Costco business centers across North America. With in-store technologies like Caper Carts and Carrot Tags, we're creating omnichannel solutions that bridge digital and physical shopping. Caper Carts, for example, are now deployed in over 15 states and are growing globally with retailers like ALDI and Kohl's. It's still early, but I'm incredibly optimistic about the role Instacart will play as the retail enablement partner that will transform omnichannel retail and accelerate growth across our ecosystem. Because of all our key advantages, Instacart continues to be the clear share of sales leader amongst digital-first players based on third- party data. To put a finer point on this, our share of sales is more than 3x larger than the next player, and we continue to attract the most new GTV to the online category. Our leadership position is driven by our ability to meet customers' full grocery needs, which means winning at big basket, $75 and up because this is where 75% of grocery sales and even more of the profits consistently lives. We continue to activate big basket customers at rates multiples higher than others, and we are also far more effective at converting small basket customers into big basket customers. When looking at our top 20 retailers that have gone nonexclusive, we see that growth on other platforms eventually plateaus that grocery basket sizes remain under $75, and we remain the share of sales leader among digital-first players at these retailers. This indicates to us that these players are fundamentally serving a different use case and further reinforces the importance of our deep retailer integrations and enterprise advantage. Sprouts, in particular, is a retailer that is more leaned into our services. And based on third-party data, we continue to fuel the strong majority of their online sales while helping them grow faster than our overall platform, too. Based on what we've seen to date, even if all our retailers were to sit on other marketplaces, we remain very confident in our ability to remain the clear category leader amongst digital-first players. Overall, the strength of our operating model reinforces our ability to deliver value for retailers and customers in addition to strengthening our Instacart Ads platform. Over the last 4 years, we scaled advertising and other revenue to now over $1 billion in annual run rate while expanding from now over 4,000 active brand partners to over 7,500. By continuing to deliver leading performance and attracting more brands to our ecosystem, we are making our platform more resilient, and we're driving more value to Carrot Ads partners and extending our scale advantage as a top 5 retail media network. Beyond our platform, we're also helping brands more effectively attract customers on partner sites like Google, Meta, Pinterest, The Trade Desk in addition to now monetizing our consumer insights data, which we believe will become even more valuable as AI transforms our business operates. Our strong financial foundation and operational discipline drive all of this. We've grown gross profit per order to over $8 in Q2. We've achieved this through our relentless focus on scale and efficiency, which includes batching more orders and shaving seconds and pennies off of our delivery cost per order. At the same time, we've made aggressive but disciplined reinvestments into our business as well as deliberate capital allocation decisions. We've made strategic acquisitions to accelerate the growth and capabilities of our enterprise offering. And cumulatively, as of the end of Q2, we've bought back over $1.6 billion worth of shares, clearly demonstrating our confidence in our ability to execute. Finally, I have to highlight AI once again because it's built into our DNA as a company, improving our customer experiences, enabling faster product launches and making our teams more impactful. More than 80% of the code we deployed in Q2 continues to be AI-assisted. And now we've also seen the volume of code deployed per engineer grow significantly with average merges per engineer up 30% year-over-year. We're also using AI to automate code reviews and reduce tech debt while transforming nontechnical functions. For example, our sales team has tripled account outreach to high-priority accounts, which resulted in twice as many meetings booked and our legal team is spending significantly less time triaging weekly e-mails. Becoming an AI-first company has fundamentally changed how we operate, and we're just getting started. As we look ahead, I could not be more confident in Chris Rogers as he steps into the role of CEO. He has played a pivotal role in everything we've accomplished from scaling ads and enterprise partnerships to developing new growth strategies. Our business would not be what it is today without him, and that's why he's a perfect person to lead Instacart into its next chapter and to further accelerate our lead in the years ahead. I know he's looking forward to stepping into the role and meeting with investors over the coming weeks, and I can't wait to see the impact that he has in this seat. I want to say a deep thank you to all our shareholders for your confidence and support. It's been an immense privilege to serve as CEO over the last 4 years. Thank you. And now I'll pass it over to Emily to cover our financials.
