Reddit RDDT Stock After Hours on Dec. 18, 2025: The Late-Day Whipsaw, Insider Sale Filing, and What to Watch Before Friday’s Open

Reddit Inc. shares capped a volatile Thursday with a modest gain into the close — then held slightly higher in after-hours trading as investors digested a mix of analyst commentary, macro tailwinds, and a fresh insider trading disclosure.

RDDT ended regular trading on Thursday, December 18, 2025, around $231.34 and traded around $232.15 after hours as of 7:59 p.m. ET, according to StockAnalysis. ^[1]

Below is what mattered after the bell on Dec. 18 — and what to keep on your radar ahead of the U.S. market open on Friday, December 19, 2025.

Reddit stock price action after the bell today

Reddit stock’s day told the story of a market that’s trading headlines and positioning as much as fundamentals:

Regular-session close: about $231.34 (up roughly 1.8% on the day) ^[2]
After-hours trading: about $232.15 (up roughly 0.35% vs. the close) as of 7:59 p.m. ET ^[3]
Intraday range:$229.45 low to $246.15 high ^[4]
Volume: about 5.1 million shares ^[5]

That “high-to-close” fade is why many traders are framing Thursday as a momentum test rather than a clean breakout.

Why Reddit stock surged early and then cooled

Analysts kept the 2026 growth narrative in play

One of the biggest Reddit-specific themes circulating on Thursday was that sell-side analysts are leaning into a 2026 digital advertising story — especially around user growth, ad product improvements, and the idea that Reddit can benefit from AI without absorbing the cost burden other platforms face.

Investor’s Business Daily’s Thursday coverage highlighted a cluster of bullish commentary, including:

Piper Sandler’s third-party estimate that Reddit’s active users rose 2% month over month in November to 953 million, extending a multi-month growth streak
Jefferies lifting its price target to $325 and naming Reddit a top pick in digital advertising
Ongoing investor focus on whether shifts in Google’s AI-driven search experiences could affect referral traffic ^[6]

That combination helps explain why the stock could push to $246+ intraday before profit-taking kicked in.

A softer inflation print boosted risk appetite across tech

The broader tape also mattered. On Thursday, markets rallied after inflation data came in cooler than forecast, which helped lift rate-cut expectations and supported higher-beta growth names. Reuters reported the CPI reading came in below expectations, pushing futures higher and yields lower. ^[7]
The Associated Press also tied Thursday’s equity bounce to the inflation update and a tech rebound helped by strong Micron-related AI enthusiasm. ^[8]

In that kind of session, Reddit — which traders often treat as a high-volatility, sentiment-driven stock — tends to amplify the moves.

The headline after the bell: Reddit officer disclosed a planned sale

One of the most concrete “after-hours” developments was a newly reported insider transaction.

A Refinitiv item distributed via Reuters on TradingView says Lee Benjamin Seong, an officer of Reddit, filed a Form 4 on December 18, disclosing:

an exercise of 68,750 shares at $7.92
a planned sale of 73,755 shares at $225.99, valued around $16.7 million
the sale was executed under a prearranged Rule 10b5-1 trading plan ^[9]

Why it matters for Friday: even when sales are 10b5-1 (and therefore often scheduled in advance), large insider-sale headlines can influence short-term sentiment — especially in a stock that already trades with big intraday swings.

Operational note: Reddit reported and resolved a video-post incident

Reddit’s own status page shows the company dealt with a product issue Thursday afternoon Pacific time: video posts not displaying correctly. The incident was marked resolved by 5:00 p.m. PST after being identified earlier in the afternoon. ^[10]

This doesn’t automatically translate into stock impact, but it’s the kind of operational “trust and reliability” detail that some investors keep in mind for ad-driven platforms — particularly during periods when the market is already jumpy.

Where Wall Street price targets and forecasts stand tonight

The target range is wide — and that’s the point

Depending on the data provider, the Street’s “average” target can look different — but the more important takeaway is dispersion: analysts do not agree on what Reddit should be worth.

StockAnalysis, citing analyst data sourced via Benzinga, lists:

Consensus rating:Buy
Average price target:$220.04
Low target:$75
High target:$325 ^[11]

That kind of spread usually signals a market still debating:

how durable Reddit’s ad momentum is,
how much incremental monetization runway exists internationally,
and how AI-driven changes to search and content discovery will affect traffic.

Recent notable analyst actions cited in current data feeds

StockAnalysis’ “latest forecasts” table also flags several recent updates, including:

Jefferies:$300 → $325 (maintained bullish stance) dated Dec. 11, 2025
Citigroup:$250 → $265 dated Nov. 3, 2025
JPMorgan:$190 → $227 (hold) dated Oct. 31, 2025 ^[12]

Separately, a Barchart write-up tied a recent Reddit move to RBC Capital Markets lifting its target to $250 while maintaining a Sector Perform stance. ^[13]

Financial forecast direction: growth expectations remain aggressive

StockAnalysis also summarizes forward-looking expectations (noting forecasts may reflect non-GAAP conventions), including:

Revenue forecast for FY 2025: about $2.19B, up sharply from FY 2024
Revenue forecast for FY 2026: about $3.03B
EPS forecast for FY 2025: about 2.32
EPS forecast for FY 2026: about 3.79 ^[14]

Even if you don’t take any single forecast as gospel, the direction is clear: the market is currently pricing Reddit like a company expected to keep compounding quickly.

What to watch before the market opens Friday, Dec. 19, 2025

Here are the key items that could move Reddit stock when U.S. trading resumes:

1) Triple witching volatility and options positioning

Friday, Dec. 19 is the year’s final major derivatives expiration day. The NYSE trading calendar explicitly flags Dec. 19 as a “Triple Witch” date. ^[15]
These sessions can bring heavier volume and faster moves — and stocks with higher volatility profiles can see exaggerated swings near the open and into the close.

2) Scheduled U.S. economic releases and Fed-related headlines

Macro can still dominate the opening tone. The BLS schedule lists several Friday releases at 10:00 a.m. ET, including Real Earnings and Consumer Expenditures annual releases. ^[16]
MarketWatch’s U.S. calendar also highlights scheduled items for Friday morning, including the Philadelphia Fed manufacturing survey and Fed-speaker listings. ^[17]

If rates move sharply on the back of any macro surprise, high-beta growth names like RDDT can react quickly.

3) Follow-through on the insider-sale headline

The Form 4 disclosure is out now, but trading impact often shows up the next morning as headlines circulate more broadly. Watch whether traders treat the sale as:

routine 10b5-1 activity (often shrugged off), or
a reason to fade Thursday’s intraday spike. ^[18]

4) Key price zones traders are likely watching

Based on Thursday’s tape and the widely cited “breakout” discussion:

Resistance zone: the $240–$246 area (Thursday’s surge and intraday high) ^[19]
Near-term support: the $229–$231 area (Thursday’s low-to-close neighborhood) ^[20]

If Reddit reclaims the upper band early Friday, momentum traders may lean in; if it loses the lower band, the next move can get fast.

5) Holiday schedule clarity for next week

For investors planning liquidity around year-end: Reuters reported that major U.S. exchanges will remain open on Dec. 24 and Dec. 26, sticking with the standard schedule (including the usual early close on Dec. 24). ^[21]

Bottom line for Reddit stock heading into Friday’s open

Reddit stock finished Thursday’s session green but choppy, with after-hours trading slightly higher — a setup that often precedes another volatility-forward day when you combine (1) momentum narratives, (2) a fresh insider-sale filing, and (3) triple-witching market mechanics.

For Friday, the most practical lens is this: RDDT is still trading like a stock where positioning and sentiment can override the day’s fundamentals. If you’re watching it into the open, focus on the overnight price reaction, derivatives-driven volatility, and any incremental analyst or filing headlines that hit the tape before 9:30 a.m. ET. ^[22]
