US banks authorize $33B in buybacks amid $1.2T S&P 500 trend

Major U.S. banks including JPMorgan, Goldman Sachs, and Citigroup authorized $33 billion in buybacks during Q1, and the Polymarket contract on S&P 500 movement for April 16 currently sits at increases_yes.

## Market reaction

S&P 500 firm buyback authorizations are on track to reach $1.2 trillion. Trading volume in the April 16 S&P 500 movement market is currently at $0. The contract covers whether the S&P 500 sees a 15% move, priced against a backdrop of U.S. tariff policy shifts and geopolitical friction.

## Why it matters

Buybacks at this scale create a structural demand floor for equities. During the U.S. “Tariff Shock” period, this corporate purchasing acts as a counterweight to selling pressure from trade frictions and rising oil prices. The $1.2 trillion authorization pace is a concrete signal of how corporate treasuries are deploying capital, not a general statement of confidence.

## What to watch

BlackRock and Vanguard’s positioning will shape how institutional flows interact with the buyback trend. Easing bank capital regulations could further accelerate repurchase activity. The S&P Dow Jones Indices Committee’s updates and any geopolitical de-escalation developments will directly affect whether the April 16 contract pays out.

Buying YES on the April 16 market would pay if the S&P 500 closes higher, a bet that the buyback trend and loosening bank regulations outweigh macro headwinds.
