As the clock ticks toward the February Consumer Price Index (CPI) release, a new kind of "game day" ritual is taking over the morning routines of young investors. Forget the NFL playoffs or the NBA finals—for the 24 million active users on Robinhood (NASDAQ: HOOD), the most exciting play of the season is the "Macro Stack."

In January 2026, Robinhood officially launched its "Custom Combos" feature, a revolutionary addition to its Prediction Markets Hub that allows users to bundle up to 10 different event outcomes into a single, high-leverage contract. With the potential for payouts exceeding 40-to-1 on "Goldilocks" economic scenarios, the feature is effectively gamifying macroeconomics for a demographic that treats Jerome Powell’s press conferences with the same fervor as a Super Bowl halftime show. Currently, the market is pricing in a 91% probability that the Federal Reserve will hold rates steady in March, but the real action lies in the "long-shot parlays" where traders are betting on a surprise rate cut paired with a core inflation miss.

The Market: What's Being Predicted

At the heart of this frenzy is the Robinhood Prediction Markets Hub, which has rapidly evolved since the platform’s first foray into election contracts in late 2024. The "Custom Combos" feature operates on a Request for Quote (RFQ) system powered by MIAXdx, the CFTC-regulated exchange in which Robinhood (NASDAQ: HOOD) acquired a 90% stake in early 2026. This vertical integration allows Robinhood to offer seamless, near-instant settlement on complex, multi-leg event contracts.

Unlike traditional prediction platforms like Polymarket or Kalshi, which typically focus on single binary outcomes, Custom Combos allow for "horizontal betting" across categories. A typical high-volume combo in early February 2026 might include:

• The CPI Leg: Predicting February YoY CPI falls below 2.3%.
• The Fed Leg: Predicting a "Pause" at the March 18 FOMC meeting.
• The Tech Leg: Predicting that Nvidia (NASDAQ: NVDA) will close the month above $1,800.
• The Political Leg: Predicting a specific outcome in a 2026 U.S. Midterm primary.

Because every "leg" of the parlay must hit for the contract to pay out at its full $1-per-share value, the cost of entry is remarkably low—often just pennies per share—creating the "lotto ticket" appeal that has long driven the success of sports betting parlays. Trading volume on the Hub has already surpassed 11 billion cumulative contracts, with "Custom Combos" accounting for an estimated 30% of new activity.

Why Traders Are Betting

The surge in "Macro Parlay" activity is driven by a cultural shift Robinhood executives call "Information Finance." For Gen Z and Millennial traders, the traditional 60/40 portfolio feels antiquated. Instead, they are using Custom Combos to express complex views on how the world works, often using these markets to "hedge their lives."

"I'm long on tech stocks, so if the Fed hikes and the market crashes, my portfolio takes a hit," explains one viral trader on X whose 5-leg "Recession Hedge" combo recently turned $200 into $8,500. "By betting on a 'Triple Threat'—high CPI, a Fed hike, and an unemployment spike—I'm basically buying insurance that pays out if my day job or my stocks are in trouble."

This "hedging life" mentality is frequently augmented by Robinhood’s "Cortex AI" assistant, which suggests "Optimal Combos" based on real-time news sentiment. If a major retailer like Walmart (NYSE: WMT) reports sluggish guidance, Cortex might prompt a user to "add a leg" predicting a dip in retail sales data, further increasing the potential payout. This creates a feedback loop where news consumption is immediately monetized, shifting the investor's role from a passive observer to an active, high-velocity speculator.

Broader Context and Implications

The timing of the "Custom Combo" craze is no coincidence. On February 4, 2026, the Commodity Futures Trading Commission (CFTC) made a landmark policy reversal, withdrawing a 2024 proposal that sought to ban "gaming" and sports-related event contracts. This move has been hailed as a "Green Light" for the prediction economy, signaling that federal regulators now view event contracts as legitimate financial derivatives rather than prohibited gambling.

However, the rise of these markets has reignited the debate over the "gamification" of finance. Critics argue that by mimicking the structure of sports betting—complete with "boosted odds" and viral "gain porn" screenshots—Robinhood is encouraging risky behavior among inexperienced traders. Proponents, meanwhile, argue that these markets serve as a "truth engine," providing more accurate forecasts than traditional pundits or polling.

Historically, prediction markets have shown remarkable accuracy in forecasting FOMC decisions and election outcomes. By aggregating the "wisdom of the crowd" into a tradable price, Robinhood is creating a real-time sentiment gauge that institutional players are beginning to watch closely. The convergence of sports betting mechanics with macroeconomic data is not just a feature; it’s the birth of a new asset class where "knowledge of the world" is the primary currency.

What to Watch Next

The immediate focus for the market is the February 13 CPI print. "Nowcast" models from the Cleveland Fed currently project a 2.34% YoY headline increase, but the spread on Robinhood suggests retail traders are split between a "cool-down" and a "sticky inflation" narrative. Any significant deviation from the 2.34% mark will likely trigger massive payouts—or liquidations—for thousands of "Macro Stacks."

Looking further ahead, the March 18 FOMC meeting remains the "Anchor Leg" for most custom combos. While a "Hold" is the overwhelming consensus at 91%, the 9% of traders betting on a cut are looking at astronomical payouts if the Fed pivots early. Additionally, as the 2026 Midterm election cycle heats up, expect Robinhood to introduce "Political-Economic Combos," where users can bet on how specific election results might impact localized economic data or sector-specific stock prices.

Bottom Line

Robinhood’s "Custom Combos" represent a fundamental evolution in how retail investors engage with the world. By lowering the barrier to entry for complex derivative trading and wrapping it in the familiar, high-adrenaline interface of a sportsbook, Robinhood has successfully turned the "dismal science" of economics into a viral entertainment product.

While the risks of high-leverage parlays are real, the success of the Prediction Markets Hub suggests that the demand for "Information Finance" is here to stay. As the CFTC moves toward a more permissive framework and MIAXdx provides the institutional-grade plumbing, the "Macro Parlay" may soon become as common in the American household as the Sunday night football bet. In this new era, the Federal Reserve isn't just a regulatory body—it’s the most watched team in the league.
