Citi: The AI super cycle is only at "halftime," S&P 500 expected to reach 8,100 by year-end!

``` Non-farm payroll data triggered turbulence in global markets, but Citigroup goes against the tide by doubling down on bullish US equities: raising the S&P 500 target and claiming the AI bull market is only halfway through; while also maintaining the expectation of a rate cut within the year. On June 5, the Nasdaq Composite Index fell 4.18%, marking its largest single-day loss since April 2025; the Philadelphia Semiconductor Index plummeted 10.26%, with the chip sector evaporating over one trillion dollars in market value in a single day—the worst performance since the circuit breakers in March 2020. Early Monday morning, the South Korean KOSPI index tumbled over 8% at the opening, dropping below 7,500 points and triggering a circuit breaker, with Japanese and Korean stock markets both closing lower. On the same day, June 5, according to Chasing Wind Trading Desk, **Citi, based on an “unprecedented” AI capital expenditure super cycle, has raised its year-end 2026 S&P 500 target substantially to 8,100 points.** Wall Street is currently extremely divided: at the micro level, AI-driven earning momentum is reshaping US stock fundamentals at an unprecedented pace; at the macro level, inflation and employment data have forced nearly all institutions except Citi to abandon expectations for rate cuts in 2026 and even start pricing in rate hikes. Citi also warned in its report that as the index climbs toward 8,100 points, downside skew risk is accumulating. **Against the backdrop that rate swap markets have fully priced in a rate hike in December, the future trend of US equities will heavily depend on whether companies can deliver on their AI profit promises. While investors embrace AI dividends, they should be wary of valuation pressure brought by tightening liquidity.**

## Earnings Forecasts Leap Significantly: AI is a True Disruptive Force Earnings are being revised up at a rare speed, forcing Citi to reassess its full-year forecast for US equities in 2026. Citi’s base prediction for S&P 500 earnings per share entering 2026 was $320, already on the high side. Its bullish scenario of $330 was also seen as "optimistic" at the time. However, Q1 results far exceeded expectations. Actual S&P 500 earnings for the quarter were about 13.4% above market consensus, a magnitude of positive surprise seen in history only at the start of economic recoveries—and currently, there is no recession backdrop. **Citi frankly stated that it had never seen such a scenario in the past forty years.** Based on this, **Citi has raised its full-year 2026 earnings forecast to $350.** The specific path: assuming each of Q2 to Q4 outpaces consensus by about +5%, corresponding to around $81 for Q2, $88 to $93 for Q3, and $90 to $95 for Q4, implying a full-year earnings of about $355, finally trimming it slightly to $350 as a “conservative yet reasonable” point estimate. For 2027, Citi gives a preliminary estimate of $400, corresponding to about 14.3% earnings growth under the base scenario, while noting considerable uncertainty for AI’s fundamental dividend sustainability after 2027. ## It’s a Capital Expenditure "Super Cycle," Not a Traditional Cycle Citi explicitly rejects defining the current environment as a "traditional cycle," asserting that it is more accurately described as a **one-off capital expenditure super cycle.** Currently, we are in the "middle innings," which means: - Earnings growth momentum has not peaked yet, but the fastest growth phase may have passed; - Future P/E ratios will face pressure; whether trailing or forward P/E, both should be expected to contract somewhat; - Future index gains will increasingly depend on earnings growth itself rather than valuation expansion. Citi particularly points out that **the current “AI picks and shovels” (i.e., AI infrastructure providers) investment logic is already fully recognized by the market. This is exactly the reason for asymmetric downside risk: the more well-known the theme, the faster the pricing reversal once slowdowns appear.** ## Positive Surprises May Persist, But Will Narrow **In the short term, Citi believes that Q2 and Q3 may still see higher-than-normal positive earnings surprises,** mainly from two sources: First, **the analyst forecast lag effect continues.** Take Nvidia as an example: the fastest upward revisions to its forward earnings occurred at the end of 2023, with its NTM EPS revised up by as much as 285% in six months. Analysts then gradually caught up, the positive surprises narrowed, but the stock price kept rising. Currently, the six-month change in equal-weight tech sector NTM EPS continues to rise, indicating it may take one or two more quarters for collective analyst adjustments to catch up with reality. This dynamic has spread from Nvidia to memory chips, and further to tech hardware and downstream data centers. Second, **tariff refund effects may bring short-term one-off gains.** Some companies have already booked the expected refunds as receivables in Q1, while others remain on the sidelines. The former’s refunds are already on the books; the latter's actual refunds may appear as Q2 profit surprises; additionally, suppliers receiving refunds may benefit purchasing firms later in the year in the form of lower sales costs (COGS).

## Valuation Cliffs and Asymmetric Risk Despite raising its target price, Citi’s report is filled with warnings about "valuation cliffs." Citi made it clear **that future index drivers will be earnings growth rather than valuation expansion. In fact, the 8,100 target price implies a lower historical P/E ratio than before.** The market has fully recognized the “picks and shovels” trade, and likely already priced in AI-related growth to 2027. But the fundamentals transmission from 2028 to 2030—i.e., from AI providers to broader AI users and conversion to actual productivity—is still unclear. Combined with last Friday and this Monday’s big declines, investors’ positions are clear: this is a market with an extremely low margin for error. The forward P/E of growth stocks converging to the 10-year average requires little compression, but since their weight in the index is very high, this valuation has an amplified impact on the S&P 500. As Citi warned, as the index rises, earning momentum is increasingly priced in, and investors need to brace for sharp volatility in the coming months caused by emotional exuberance and rate hike bets. ~~~~~~~~~~~~~~~~~~~~~~~~ The above highlights are from [Chasing Wind Trading Desk](https://mp.weixin.qq.com/s/uua05g5qk-N2J7h91pyqxQ).
