The prediction was explicitly conditional:
If you don’t see [inflation] change in the next three months, you’re going to see 75/25 for a hike of at least 25 basis points.
That is, only if U.S. inflation dynamics failed to improve materially between roughly April 11 and mid‑July 2024 did Chamath expect market‑implied odds to move to about 75% for a Fed rate hike (vs. a cut).
1. What actually happened to inflation (the condition)
- March 2024 CPI was hot: headline 0.4% m/m and 3.5% y/y; core CPI 0.4% m/m and 3.8% y/y, with the 3‑month annualized core rate around 4.5%, prompting concern that inflation was re‑accelerating. (cnbc.com)
- From April through June 2024, inflation clearly cooled:
- April: CPI up 0.3% m/m and 3.4% y/y; core 0.3% m/m and 3.6% y/y, the lowest core reading since April 2021. (cnbc.com)
- May: headline CPI flat m/m (0.0%) and 3.3% y/y; core 0.2% m/m and 3.4% y/y, also the lowest annual core since April 2021. (cnbc.com)
- June (reported July 11): CPI fell −0.1% m/m and 3.0% y/y, its lowest in over a year; core rose just 0.1% m/m and 3.3% y/y, the smallest annual core increase since April 2021. Several analyses noted that over the prior three months, inflation was running at about a 1% annualized pace, emphasizing a renewed disinflation trend. (cnbc.com)
This is a material improvement in inflation dynamics over the three months after his statement: sequential slowing in April and May, then outright negative monthly CPI and very soft core in June. The antecedent of his conditional (“if you don’t see this thing change in the next three months”) therefore did not occur.
2. What actually happened to market‑implied odds by mid‑July 2024
Even though the condition failed, we can look at real‑world pricing:
- After the soft June CPI release on July 11, 2024, CME FedWatch data (via CNBC) showed markets pricing >80% odds of a September rate cut, with investors increasing, not decreasing, cut expectations. (cnbc.com)
- Other coverage just before and around that time similarly reported FedWatch probabilities showing a strong majority chance of cuts by September and essentially no market focus on hikes. (benzinga.com)
So in the actual path of the world, odds moved in the opposite direction of his described 75%‑for‑a‑hike scenario—but that was in a world where inflation did improve.
3. Why the outcome is scored as ambiguous
Chamath’s forecast is about a counterfactual: what Fed‑funds futures would look like if inflation had stayed hot and not “changed” over the next three months. In reality, inflation cooled materially, so the condition attached to his prediction was false. Forecast‑evaluation frameworks typically treat such conditional predictions as not testable when their condition doesn’t occur.
- We can say that the world he described (high hike odds) did not match the world we got, but we cannot infer from that whether he was right or wrong about what markets would have done under his specified “no improvement in inflation” scenario.
Because the antecedent of the conditional failed, and the statement was explicitly conditional, the correctness of his specific claim about “75/25 for a hike” cannot be determined from realized data.
Hence the appropriate label is "ambiguous" rather than right or wrong.
