Davis Giangiulio
Davis Giangiulio reports on prediction markets and their growing role in finance, using trader odds on platforms and derivatives markets to explain how investors price in economic data, central bank decisions and political events for CNBC. His coverage sits at the junction of event contracts and traditional markets, translating percentage probabilities into clear narratives about risk, regulation and market sentiment. Alongside this specialty, he produces fast-turn market stories on equity moves and analyst calls, giving a real-time view of how news and forecasts move stocks and indices.
Prediction Markets as a Lens on Finance and Policy
Giangiulio’s core beat is prediction markets, and he treats them as a window into how traders and speculators understand future events in finance and public life.
He has written about platforms such as Kalshi requesting permission from regulators to offer margin trading, explaining how allowing users to buy contracts with borrowed funds would change the leverage and risk profile of these markets. In stories on Polymarket, he reports on how the company restructures its marketing and governance and seeks Wall Street liquidity, framing those moves as part of an effort to professionalize event-based trading ahead of expected growth.
He regularly covers how prediction markets track Federal Reserve decisions, detailing odds on rate hikes or pauses across multiple platforms and comparing them to fed funds futures and other traditional indicators. One story on the September Fed meeting walks through changing probabilities after a central banker’s speech, showing how odds on Kalshi and Polymarket shifted as traders digested the commitment to fight inflation and recalibrated expectations for a quarter-point move.
In another, he uses weak jobs data and CME FedWatch probabilities to explain why traders assign a lower chance to a near-term rate increase while still leaving the door open for tightening later in the year.
Giangiulio also follows prediction markets into politics and sports, examining how state laws on election betting apply to event contracts and how that uncertainty affects platforms that list political markets.
He has covered a letter from a major sports league calling for certain sports-related betting contracts to be banned, using that episode to show how established stakeholders in sports gambling are responding to the spread of novel trading products. Across these pieces, he treats prediction markets as financial instruments embedded in legal and cultural frameworks, not just curiosities, and he spends reporting time on statutes, regulators and institutional responses as well as odds and payouts.
Real-Time Market Moves and Trader Positioning
Beyond event contracts, Giangiulio writes frequent “stocks making the biggest moves” pieces that track premarket and midday action in individual names, tying price moves to catalysts such as earnings, analyst upgrades or downgrades, executive changes and clinical trial results. In one recent midday story, he covers sharp moves in MongoDB, Boeing, Kodiak Sciences, Roblox and Nvidia, linking each swing to news such as a CEO departure, a brokerage downgrade or a successful Phase 3 study in eye treatments. Other rundowns list stocks like Rogers, United Therapeutics, Moderna, FormFactor and various large-cap names, giving a concise explanation for why each ticker is moving more than the broader market.
He contributes to broader market wraps that describe how major indices respond to macro data and yield moves, such as pieces on the S&P 500 starting October higher as Treasury yields retreat, or stocks rising after soft jobs data with Nvidia leading the Nasdaq to an intraday record. In coverage of U.S. Treasury yields, he highlights the benchmark 10-year yield’s reaction to weaker-than-expected nonfarm payrolls and connects the move to shifting expectations for the Fed’s October decision.
These stories show a consistent approach: pairing index and yield levels with specific data points and trader expectations to explain why markets are moving, rather than simply recording the moves.
Single-Stock and Sector Calls from Wall Street
Giangiulio also writes about analyst calls and corporate developments that shape investor sentiment toward specific companies and sectors.
In a piece on a cruise line operator, he outlines Bank of America’s view that the stock’s roughly 26% decline from its recent peak is overdone, explaining the upgrade to a buy rating and the implied upside from the bank’s price target. He uses that call to place the stock’s drop in context and signal how major sell-side firms are positioning in travel-related names.
Another story focuses on a cybersecurity company that one research firm calls the likely winner in the AI “agentic” era, summarizing the rationale for that view and connecting it to broader themes in artificial intelligence and security spending. In coverage of Citadel’s unwinding of more than 80% of the risk tied to a portfolio of assets acquired from Leopold Aschenbrenner’s Situational Awareness, he draws on a client letter to quantify the block trades and performance of the firm’s multistrategy fund.
These pieces show his comfort translating analyst notes and hedge fund communications into clear, data-driven articles that emphasize positioning, risk reduction and forward-looking narratives for investors.
Range of Work and Background
Giangiulio holds an associate producer/writer role at CNBC and covers prediction markets in a cross-platform capacity, a job that builds on earlier markets reporting work at the same masthead. His author biography notes that his work on the economy, politics, culture and more has been featured in both local and national outlets, reflecting a broader reporting background beyond financial markets.
In his professional summary, he describes six years of experience reporting and writing on business, politics, policy, health, culture and other topics, with stories ranging from breaking news and quick-turn dailies to research-heavy enterprise features.
Before focusing on prediction markets, he freelanced on economics, politics, education and culture, with work appearing in national and regional outlets such as Business Insider, MarketWatch, Teen Vogue and The Philadelphia Inquirer. That history informs his current beat: he treats prediction markets not only as trading tools but as instruments that intersect with elections, sports, regulation and the broader cultural conversation around risk and speculation. His own description of the role emphasizes that these platforms are seeping into financial institutions and the wider zeitgeist, and that coverage is still being defined, which aligns with his mix of daily odds tracking, regulatory reporting and enterprise pieces on how these markets are organized and governed.
