DraftKings Inc. (DKNG) stock is falling Tuesday, extending a monthly decline.

Two regulatory developments are weighing on the online betting sector: Brazil's ban on online sports betting and a House committee's expanded insider trading investigation.

House Probe Expands

On Tuesday, Rep. James Comer, chair of the House Oversight Committee, sent letters to the CEOs of Hyperliquid Labs, Crypto.com and Aristotle Exchange Inc., which owns PredictIt.

CNBC first shared the letters. Comer said the committee is investigating "whether these platforms are fulfilling their legal obligations and doing enough to identify and prevent insider trading before it happens." DraftKings was not named.

Brazil's Ban Pressures Flutter

Flutter Entertainment Plc (FLUT), which owns FanDuel, halted its Brazil betting and iGaming operations after the ban took effect September 25.

The order needs congressional approval within 120 days. Flutter estimated a prolonged shutdown could cost about $70 million in 2026 revenue.

DraftKings has no direct exposure to the order, and its stock fell Monday likely in sympathy with Flutter.

Technical Analysis

DKNG is in a longer-term downtrend, and the moving-average stack reinforces it: the stock is trading 10.6% below its 20-day SMA ($23.00) and 20.8% below its 200-day SMA ($25.97). The bearish crossover structure also remains in place, with the 20-day SMA below the 50-day SMA and a "death cross" (50-day below 200-day) that first appeared in October 2025.

Momentum is also leaning against the bulls right now: MACD is below its signal line and the histogram is negative, which points to fading upside pressure versus the prior upswing. In plain English, when MACD sits below its signal line, it often means rebounds are losing steam unless buyers can quickly reclaim control.

From a levels perspective, the chart is compressing between nearby inflection points:

• Key Resistance: $24.50 — a nearby ceiling that lines up with a prior pivot zone and sits below the 100-day SMA ($24.79), where rebounds can stall
• Key Support: $20.50 — a near-term floor sitting just above the 52-week low ($20.35), making it a high-visibility "line in the sand" for dip buyers

DKNG Price Action: DraftKings shares were down 4.54% at $20.20 at the time of publication on Tuesday. The stock is trading at a new 52-week low, according to market data.
