Thank you, Ken. Good morning, and thanks for joining us today. First off, I'd like to welcome Jill Griebenow, our new Chief Financial Officer on the call. During her 12 year tenure at Cboe, Jill has helped held many roles across our global organization and has an incredible understanding of our business, bringing the breadth and depth of expertise needed to serve in this role. Her leadership has helped drive our vision and strategy, enabling us to become the global market powerhouse we are today, and I'm happy to have her at the helm as CFO. I'm pleased to report on strong second quarter earnings for Cboe. During the quarter, we grew net revenue 10% year-over-year to $467 million, and adjusted EPS by 7% to $1.78. These results were driven by strong volumes across our Derivatives franchise, specifically our proprietary index options products and the continued global expansion of our Data and Access Solutions business. Our Derivatives business delivered another outstanding quarter, as total organic net revenue increased 21%, driven by the strength of our index options and volatility products and continued solid volumes in multi-listed options trading. During the quarter, total net revenue in our Data and Access Solutions business increased 9% and organic revenue growth increased over 7%. Total net revenue in our Cash and Spot Markets business decreased 11% during the quarter. Cboe's efforts to achieve its environmental, social and governance goal continued to gain momentum. Last month, we published our fifth annual ESG report. In addition to disclosing our Scope 1 and Scope 2 emissions. This year for the first time, we disclosed our relevance to Scope 3 emissions in our report. We plan to continue to make strides forward each year with our ESG program. In the second quarter, we advanced our top strategic growth priorities, which include Derivatives, Data and Access Solutions and Cboe Digital, recording wins across each of these priorities during the second quarter. I will turn to Derivatives and Data and Access Solutions in a moment. But first, I want to provide an update on Cboe Digital. During the quarter, Cboe Digital recorded solid volumes with ADV of more than $50 million and $4.6 billion total traded on our spot market. We were also pleased to receive regulatory approval to expand our product offering to include margin futures contracts, which we plan to launch later this year, making Cboe Digital the first US regulated crypto native exchange and clearinghouse platform to offer leverage Derivatives products. The initial product rollout will include physically and financially settled Bitcoin and either contracts and will help enable customers to trade futures in a much less capital intensive way. We are working with our customers and the CFTC in preparation for launch and look forward to bringing this unique product to the market. As the digital asset market continues to evolve, we remain highly active in discussions with regulators and policy makers. We continue to see engagement from market participants about the opportunities this asset class affords and will continue to leverage our trusted, transparent, and regulated market structure to advance the industry forward. Our Derivatives ecosystem continue to flourish in the second quarter as traders and investors utilize our flagship VIX and S&P 500 Index Options products across an ever changing market environment. As we have evolved our suite of products in recent years, we have created flexible products that provide opportunities for customers of all dimensions to trade a contract with its right size for them on a timeframe that suits their unique needs. Together, our VIX and SVX products anchor a remarkable toolkit that is available for investors to help find opportunity and hedge their portfolios in changing market environments. During the second quarter, volume in our proprietary index options products increased 38% year-over-year, while multi-listed options increased 2%. In June, we reached new record monthly ADV of 3.9 million total index options contracts traded. SPX options ADV increased 33% to a record 2.8 million contracts during the quarter. We also continued to see strong momentum in our mini SPX options contract, known by its ticker symbol XSP, which increased 142% year-over-year. ADV for SPX options opened on the same day of expiration, otherwise called 0DTE, comprised nearly 44% of overall SPX volumes in the second quarter. As we’ve noted before, we believe there has been a fundamental evolution in how customers are trading this product and we anticipate this volume to continue. Given this strong customer interest, we continue to focus on the development of a short-term tradable product that is designed to allow customers to more effectively trade daily moves in the market. While interest in 0DTE trading has gained a lot of attention, we continue to see strong volumes in our standard monthly SPX options contract that expires on the third Friday of every month, with average open interest up 12% in June 2023 compared to one year ago. While the VIX Index remained at historically low levels during the second quarter, we saw a significant increase in trading activity in VIX options with a 53% increase year-over-year to an ADV of 778,000 contracts, our fourth best quarter on record. Given the flexibility and utility that both VIX and SPX options provide in changing market environments, we see customers utilizing both products interchangeably to manage and hedge their risk. And globally, demand for our products continued with SPX and VIX options ADV during global trading hours increasing 81% and 16%, respectively versus the second quarter of 2022. Through our strong foundation of proprietary index options products, we are able to further expand our diverse offerings with new products designed to help meet the evolving needs of our growing global customer base. Last month we launched options on our corporate bond index futures, bringing a new options on futures functionality to Cboe Futures Exchange which we can leverage for additional products in the future. This quarter we also anticipate that FINRA will receive regulatory approval for new margin requirements recently adopted by Cboe related to cash settled index options written against ETFs that track the same index underlying the option. Specifically, customers who are writing options against indices that are offset by an underlying ETF, for example XSP versus long SPY stock, will receive margin relief enabling greater capital efficiencies in their trading. And in partnership with S&P Dow Jones Indices, we plan to launch a new Cboe S&P 500 Dispersion Index next month. Dispersion is recognized as one of the fundamental metrics of market risk. A strategy that is predominately traded in the over-the-counter market, this new index aims to standardize the measurement of S&P 500 dispersion. Additionally, we are preparing for the launch of single stock options on our Cboe Europe Derivatives Exchange in the fourth quarter of this year, with active engagement from market participants and other members of the ecosystem who share our vision of growing the market and delivering a simpler and more efficient pan-European trading and post-trade experience. We look forward to providing an update on these initiatives during our next earnings call. Turning to our Data and Access Solutions business. We continue to see solid growth, with total net revenue increasing 9%, up 7% on an organic basis during the quarter. The second quarter results build on the strong demand we see globally from customers for our high quality data and access to our markets. As we look to the second half of the year, we anticipate new opportunities across our Data and Access Solutions ecosystem will help drive further growth, including demand for Australian equity market data now that Cboe Australia has migrated its exchange technology to Cboe’s uniform trading platform. As we continue to leverage our global footprint and expanded customer base, we also see opportunity to expand our reach of our proprietary data products, such as our Cboe One data feeds and Cboe Global Indices offering. We continue to focus on our sales and marketing efforts in new regions to introduce market participants to the unique value proposition of our unrivaled data offering. During the second quarter, we announced the launch of Cboe Global Listings, a first-of-its-kind global listings network which aims to facilitate worldwide access to capital and secondary liquidity for companies and ETFs. Our new listings offering draws on our deep markets expertise, regional experience in all the jurisdictions where we operate, and the combined strength of our global equities exchange network to provide locally optimized and centrally coordinated listing services and support for issuers. The expansion of our listings business rounds out our global equities offering, helping to enable market participants around the globe to utilize Cboe markets for more uniform access to equities trading, market data and listings. Performance in our Cash and Spot Markets reflected the overall muted volumes we saw across all global equity markets in the second quarter. In Europe, the Cboe Europe Equities business increased second quarter market share by one percentage point year-over-year to 23.8%. Additionally, Cboe BIDS Europe experienced another strong quarter with 35.8% market share and remained the largest European block trading venue. Cboe Clear Europe market share grew to 33.8% in the second quarter, up from 31.3% in the prior year quarter. During the quarter, Cboe Clear Europe also announced plans to introduce securities financing transactions, or SFTs, in 2024 subject to regulatory approvals. Cboe aims to bring this new service to the market to help ease capital requirements for market participants through a centrally cleared service for stock lending. SFT is yet another example of Cboe taking market feedback, leveraging our expansive ecosystem, and building tangible solutions for our customers. Turning to Asia-Pacific. Cboe Australia market share grew to 18.2% in the second quarter, up from 17% in the previous year. In Japan, equities market share was 4.1% during the second quarter, up from 3.5% in the second quarter of 2022, and we remain on track for the Cboe Japan technology migration and expected launch of Cboe BIDS Japan in the fourth quarter of this year, subject to regulatory approval. With the launch of Cboe BIDS Japan, the BIDS network will now extend to seven of the top 10 global equity markets, creating a one-of-a-kind global equity block trading network. In our global FX business, net revenues were up 7% year-over-year in the second quarter as the business expanded spot market share to a record 19.5%, up from 17% a year ago. Our NDF offering, which trades on Cboe SEF, our swap execution facility, continued to see strong results with volumes increasing 23% during the second quarter with ADV of $937 million. To meet this increased customer demand, we launched a new London matching engine for Cboe SEF during the second quarter. With Asia currency pairs accounting for a significant portion of Cboe SEF volumes, this new matching engine is expected to enhance our service to customers based in Asia and Europe, further diversify order flow on the platform and create greater matching opportunities for our clients. In summary, Cboe delivered another solid quarter, building on our record first quarter results. With our strong foundation of Derivatives, Cash and Spot Markets, coupled with our Data and Access Solutions, we have the ability to continue to harness the power of these markets to create new products and services that deliver innovative products to our customers. We will continue to plant the seeds of opportunity that will help allow us to harvest investments across all seasons to drive consistent growth and value for our shareholders. With that, I will turn it over to Jill.
