#Gate股票观点挑战 ➕ $RDDT Reddit: can S&P 500 demand turn a brutal post-earnings reset into the next breakout?

The setup around Reddit has become much more interesting at roughly $150–$151. RDDT entered the S&P 500 on August 18, a major milestone that should expand its exposure to passive funds and ETFs tracking the index. Reddit itself confirmed the inclusion became effective before the August 18 market open.

But here is the part I find more important: the stock did not simply continue higher after the inclusion. Instead, the market has been aggressively repricing expectations after earnings. RDDT closed at $150.32 on August 20, down 0.92% on the day, after falling from $178.09 on August 14. On August 17 alone, the stock dropped 7.63%, and the post-earnings volatility has remained intense.

That creates a fascinating battle between two forces:

S&P 500 index demand vs. post-earnings selling pressure.

The question for me is no longer whether Reddit has growth.

It clearly does.

The real question is whether that growth is strong enough to overcome investors’ concerns about valuation, search traffic and user engagement.

THE FUNDAMENTALS ARE STILL IMPRESSIVE

Reddit's Q2 2026 numbers were objectively strong.

Revenue reached approximately $805 million, representing 61% year-over-year growth, while advertising revenue increased 64% to about $762 million. Reddit also reported its eighth consecutive quarter with revenue growth above 60%, alongside GAAP profitability and gross margins above 90%.

Those numbers make the post-earnings selloff look unusual at first glance.

If a company grows revenue by more than 60% and advertising revenue by 64%, why would investors sell it aggressively?

Because the market is not only paying for what Reddit delivered.

It is pricing what Reddit can deliver next.

AND THAT IS WHERE THE USER STORY GETS COMPLICATED

One of the biggest concerns is Reddit's traffic and user-growth trajectory.

The company has been facing uncertainty around search referral traffic, particularly as Google and AI-powered search products increasingly answer questions directly instead of sending users to external websites.

That matters because Reddit has historically benefited enormously from search-driven discovery.

Investors therefore want to know whether Reddit can convert more of its existing audience into highly engaged, directly monetizable users rather than depending too heavily on external search traffic.

Recent analysis noted that Q2 daily active user growth slowed to around 18%, compared with 21% previously, increasing concerns about the sustainability of user expansion.

This explains why the market reaction was so different from the headline earnings numbers.

The business delivered strong financial growth, but investors started questioning the durability of the growth engine.

THE AI THREAT COULD ALSO BECOME AN OPPORTUNITY

This is where Reddit's story becomes much more complicated.

AI could take traffic away from Reddit.

But AI could also make Reddit's enormous database of human conversations increasingly valuable.

Reddit says its platform contains more than 26 billion posts and comments and more than 130 million daily active uniques. The company has already built relationships around AI data licensing, turning user-generated content into a potential monetization opportunity.

That creates two opposing scenarios.

AI search could reduce traditional web traffic.

But AI companies may simultaneously pay more for access to Reddit's unique human-generated information.

The winner will be determined by which effect becomes economically larger.

THE S&P 500 CATALYST IS REAL — BUT IT IS NOT MAGIC

Reddit's inclusion in the S&P 500 is unquestionably significant.

Index-tracking funds generally need to own newly added constituents, creating additional demand around the effective inclusion date. Reports before the inclusion suggested passive funds and ETFs could require substantial purchases of RDDT shares.

That helped explain the powerful move before inclusion.

RDDT jumped 12.63% on August 14, closing at $178.09 after the S&P 500 announcement. Volume exploded to approximately 21.5 million shares, compared with only a few million shares on several normal sessions.

But then came the reality check.

The stock reached $178.34 on August 17 before closing at $164.50, then fell to $158.25 on August 18 and $151.71 on August 19.

This tells me that index demand can create a powerful short-term catalyst, but it cannot automatically overpower fundamental concerns.

THE $150 LEVEL IS NOW THE BATTLEFIELD

At approximately $150–$151, RDDT is sitting near a technically important area.

The stock previously traded around $149.51 on August 6 and $150.87 at the close that day, while the August 20 session opened near $149.61. That makes the $149–$151 region an obvious near-term area for bulls to defend.

If buyers repeatedly defend $150 and volume begins expanding on rebounds, the market could be building a base.

The first recovery zone I would watch is approximately $158–$161, followed by $164–$166.

Above that, the $175–$178 region becomes a much bigger test because that is where the recent S&P-driven rally stalled.

A sustained break above $178 would materially improve the technical picture.

But there is another side.

If $150 breaks decisively with heavy selling, the market could revisit the $140–$145 region, with the late-July low around $135 becoming a deeper downside reference.

BULLISH CASE: INDEX DEMAND MEETS REAL GROWTH

My bullish scenario is straightforward.

If S&P 500-related demand continues to provide a liquidity floor while Reddit maintains 60%+ revenue growth, advertising remains strong and AI partnerships develop into meaningful revenue streams, RDDT could eventually rebuild momentum.

The technical confirmation I would want is:

$150 holds → $160 reclaimed → $165 breaks → $178 resistance challenged.

A clean move through $178 with strong volume would be the first convincing sign that the post-earnings selloff has been absorbed.

At that point, the market could begin looking toward the $185–$200 region.

That is a scenario, not a guaranteed target.

BEARISH CASE: THE MARKET WANTS PROOF, NOT PROMISES

The bearish argument is equally compelling.

RDDT has already shown how quickly investors can punish the stock when expectations change. Following Q2 earnings, shares dropped around 21% amid concerns about search referral traffic and user growth despite the strong financial results.

If search-driven traffic continues weakening, daily active growth slows further, or AI tools increasingly replace Reddit visits, the market could compress the valuation even if revenue continues growing.

In that scenario, $150 would become a critical line rather than a launchpad.

A decisive breakdown below $150 would weaken the rebound thesis.

MY TRADING FRAMEWORK

I would not chase RDDT simply because it is now an S&P 500 constituent.

The better setup, in my view, is confirmation.

Bullish entry idea: wait for $158–$161 to be reclaimed with improving volume, then watch $165 and $178.

Breakout setup: a strong close above $178 could signal that buyers are finally absorbing the post-earnings supply.

Pullback setup: if $150 holds and the stock forms a higher low, the risk/reward becomes more interesting.

Invalidation: a sustained break below $150 would make me defensive, with $140–$145 and then the ~$135 area becoming important downside references.

These are analysis levels, not guaranteed outcomes.

THE BIGGER QUESTION IS NOT THE INDEX

S&P 500 inclusion can create demand.

It can increase institutional visibility.

It can improve liquidity.

It can put Reddit in front of a much larger universe of passive investors.

But none of those factors permanently replace business fundamentals.

The next major catalyst is therefore not simply another index rebalance.

It is proof that Reddit can continue monetizing its enormous audience while navigating the biggest structural change to internet search in years.

If Reddit turns AI from a traffic threat into a monetization engine, the current valuation debate could look very different later.

If AI instead becomes a structural reason for users to stop visiting Reddit directly, the earnings growth rate could eventually slow.

That is the real investment battle.

MY VERDICT ON RDDT

At around $151, I see a stock caught between exceptional financial growth and elevated expectations.

The numbers are difficult to ignore:

61% Q2 revenue growth.

64% advertising growth.

$805M quarterly revenue.

$762M advertising revenue.

S&P 500 inclusion.

But the risks are equally real:

Search traffic uncertainty.

Slower user-growth momentum.

High expectations.

Aggressive post-earnings selling.

AI competition for web attention.

That makes me cautiously bullish rather than blindly bullish.

For me, $150 is the line to watch.

Hold it, build a base and reclaim $160–$165, and the rebound case starts becoming much more convincing.

Break $178 with volume, and the market may finally prove that S&P 500 inclusion was not just a temporary catalyst.

Lose $150 decisively, and patience becomes more attractive.

The S&P 500 gave Reddit a bigger stage.

Now Reddit has to prove that its growth deserves the valuation.

My view: RDDT can recover, but I want confirmation above resistance rather than chasing the stock at $151 simply because the index inclusion story sounds bullish.
